IVAeris Oy – General Terms and Conditions

Valid from 1 January 2024. Updated 8 March 2026.

IVAeris Oy reserves the right to amend these terms and conditions unilaterally. Amendments take effect immediately for new orders. Each order is governed by the terms and conditions in force at the time the order is placed, as published on the IVAeris Oy website. Changes required by law take effect immediately unless the law provides otherwise.

1. Scope and Definitions

1.1 Scope of Application

These general delivery, maintenance and contract terms apply to agreements between IVAeris Oy and the Customer where these terms have been referred to or have otherwise become part of the agreement. These terms form an integral part of the agreement between the parties. These general terms are not intended to deviate from mandatory consumer protection legislation applicable to consumer transactions.

1.2 Mandatory Consumer Protection Provisions

These terms apply to consumer customers to the extent they do not conflict with the Consumer Protection Act (38/1978) or other mandatory consumer protection legislation. Under no circumstances do these terms narrow or remove a consumer's statutory rights. In particular, the consumer's statutory rights prevail in the following situations: warranty periods and liability for defects, complaint periods for latent defects, and unfair contract terms in consumer agreements. For B2B customers these terms apply in full, and YSE 1998 serves as a supplementary dispute resolution framework to the extent agreed in these terms.

1.3 Confirmations via Communication Channels

IVAeris Oy does not accept verbal orders. All orders, changes and contractual amendments must be made in writing (email, text message, WhatsApp or other permanent communication channel). A written order is a prerequisite for the formation of a contract. Orders and confirmations given by email, text message, WhatsApp or other written communication channels are considered legally binding.

1.4 Definitions

Equipment: Refers to equipment manufactured by IVAeris Oy or its principal, as well as spare parts and accessories supplied by IVAeris under these terms.

Spare Part: Refers to spare parts and accessories manufactured and supplied by IVAeris or its principal.

Software: Refers to the operating software of the equipment and its associated controller maintained or supported by IVAeris under these terms. This definition does not cover customer-specific adaptations or modifications, or third-party software.

Service: Refers to maintenance, upkeep, equipment support, installation, consulting, training and/or other expert service as defined in the agreement.

Delivery Date: Refers to the date on which IVAeris has completed the installation or maintenance work in accordance with its specifications, or, if the Customer installs the equipment, the date on which the equipment is handed over to the Customer.

2.6 Changes

IVAeris Oy reserves the right to change prices and delivery terms without prior notice. The Customer must review the current delivery terms before placing an order.

IVAeris Oy treats all customer data as strictly confidential and does not disclose personal or customer data to third parties. For the purpose of fulfilling an order, the Customer's contact details (name, address, phone number) are passed to Posti Group Oyj. This processing is based on the performance of a contract (GDPR Art. 6(1)(b)) and does not require separate consent.

When placing an order, please provide all relevant details as accurately as possible.

2.7 Ordering

Available products and services are listed on the IVAeris website. Orders should preferably be placed by email or message. When ordering via the online store, add products and services to the shopping cart and complete the order by paying through the checkout. By placing an order you accept these delivery terms, product prices and delivery charges. An order confirmation is sent by email listing the ordered products and price.

3. Execution of Work, Delivery, Installation, Cleaning and Liabilities

3.1 Delivery Changes

Any observations or changes to an order must be communicated no later than two (2) weeks before the scheduled delivery. Changes may be submitted by phone on 010 206 3000 or by email to info@aeris.fi.

3.2 Delivery Time

IVAeris delivers equipment at the agreed delivery time or, if no delivery time has been specified, within a reasonable time after the agreement enters into force. The start date and time of services are agreed separately.

3.3 User Manuals

One copy of the current documentation for the equipment is included with delivery. User manuals are in Finnish unless the manufacturer provides documentation only in English.

3.4 Delivery Terms

Unless otherwise agreed in writing, the delivery term for equipment is ex IVAeris warehouse in Espoo. Transport costs (freight and insurance) from the IVAeris warehouse to the delivery location are charged by IVAeris in accordance with its current pricing.

3.5 Equipment Installation

Unless otherwise agreed in writing, the Customer is responsible for installing the equipment, in which case delivery is deemed to have occurred when the equipment has been delivered to the Customer. The Customer may separately order installation services from IVAeris for equipment whose installation is the Customer's responsibility; IVAeris will then provide the service in accordance with its current terms and pricing. If IVAeris is responsible for installation, delivery is deemed complete when IVAeris has finished the installation work in accordance with its specifications, unless the equipment order and installation order were placed separately. If there are two separate orders, the installation does not affect the terms of the equipment order.

3.6 Installation Readiness and Workplace Preparation

The smooth execution of every job requires clear ground rules. IVAeris Oy always strives to act fairly and in a customer-oriented manner, but a successful outcome requires responsibility and forward planning from both parties.

By ordering the work, the Customer accepts these terms and understands that workplace preparation, unobstructed access and protective measures are the Customer's responsibility unless otherwise agreed. IVAeris Oy is liable for damage caused by the work only if it results from gross negligence or intentional conduct, and under the insurance terms only if the damage is sudden and unforeseeable. Long-term, gradual or latent damage (such as moisture or mould damage, accumulation of dust, hidden defects) that does not result from a single sudden event is not covered by the liability insurance and does not fall within IVAeris Oy's liability.

3.6.1 Unobstructed Access and Workplace Preparation

• The Customer must ensure that the equipment can be moved to the installation location without obstruction.

• If the equipment cannot pass through a door, corridor or other access route to the installation location, IVAeris Oy is not liable for any resulting delays or additional costs.

• The Customer must ensure that ventilation ducts, electrical work and other preparatory measures have been completed before installation.

• If the equipment cannot be installed due to inadequate preparation of the Customer's premises, an hourly standby charge per installer will be invoiced from the time the crew departs from the office until they return.

3.6.2 Surface and Environmental Protection

The work should not cause significant soiling indoors, but the Customer is responsible for ensuring that particularly sensitive items – such as rugs, decorative objects and electronics – have been removed from the work area before work begins.

If heavy machinery or other specialist equipment is used, the Customer must protect floors, walls and other surfaces against potential damage unless otherwise agreed in writing.

3.6.3 Handling of Workers' Equipment

The work crew's clothing and footwear may carry adhesive, oil or other substances. The Customer must provide a space where workers can remove their equipment without risk of damage to the Customer's property.

3.6.4 Measurement and Balancing

Where the installation carried out by IVAeris includes measurement and balancing of the ventilation system, this is performed as a differential pressure measurement by measuring airflows from the terminals in accordance with the ventilation design.

• If no ventilation design is available, IVAeris will perform the balancing using airflow values calculated on the basis of the floor area and volume of the dwelling.

• The Customer must ensure that the ventilation ducts are clean and free of leaks or blockages.

• If ventilation terminals have been painted onto or otherwise fixed to wall materials, IVAeris is not liable for any wall damage that may arise from removing them.

3.6.5 HVAC Duct Cleaning (Duct Sweeping)

Where ventilation duct cleaning is performed or duct sweeping has been agreed as part of the installation, the work is carried out using a negative-pressure vacuum. The aim is to remove dust, dirt and any blockages accumulated inside the ducts to achieve the best possible result.

Each ventilation duct is treated individually where possible using a mechanical rotating brush. IVAeris Oy does not guarantee that all ducts can be fully swept due to the following reasons:

• Fragile duct materials: In some cases the duct material cannot withstand mechanical cleaning. For example, flexible corrugated pipe, old cardboard ducts or thin plastic ducts may be damaged during cleaning. In such cases cleaning is carried out using lighter methods or left partially uncompleted.

• Obstructions and actuators in ducts: Dampers, ventilation terminals, silencers and other actuators may prevent the brush from passing through the duct system. Cleaning is carried out as far as possible, but if obstructions cannot be removed the sweeping will be partial.

• Inadequate cleaning hatches: Cleaning hatches are essential for thorough duct sweeping. If the Customer does not order the installation of cleaning hatches, or if their installation is structurally impossible during the work, cleaning is performed from available hatches and terminals as best as possible.

3.6.5.1 Interruptions and Best-Effort Performance

If sweeping is interrupted due to structural problems, the work is considered completed to the best possible standard without a separate credit.

• If ducts have collapsed, are blocked or damaged, IVAeris Oy may provide the Customer with recommendations for further action such as replacing ducts or adding cleaning hatches.

• If ducts cannot be cleaned for technical or structural reasons, the Customer is still obliged to pay for work already done and for work preparation.

3.6.6 Liability Questions

IVAeris Oy is not liable for damage caused to unprotected surfaces, furniture or other objects, such as soiling, surface scratches, staining, accumulation of dust or indentations left by tools.

It is the Customer's responsibility to ensure that surfaces and objects in the work area are adequately protected before work begins. If the work requires special protection (e.g. covering floors for heavy tool use), the Customer must arrange it themselves or agree it separately with IVAeris Oy.

IVAeris Oy is, however, directly liable for serious and foreseeable damage resulting from gross negligence or intentional conduct. This limitation of liability does not apply to damage caused by the gross negligence or intentional conduct of IVAeris Oy's personnel – for such damage IVAeris Oy is fully liable. For other damage, liability is limited to the value of the service performed and does not cover indirect damage such as loss of profit, loss of earnings, third-party claims or other consequential costs.

3.6.7 Electric Vehicle Charging and Energy Costs

If an IVAeris Oy electric vehicle is charged from the Customer's building electricity supply during the work, the procedure is agreed separately at the time of the service visit. For consumer customers, charging always requires explicit consent. For B2B customers, whether charging is available or declined is notified at the start of the job. If charging is not possible, the service travel charge is increased by EUR 10 (incl. VAT 25.5%) per visit as an energy cost. If energy consumption is higher than usual, this is agreed separately before work begins.

3.7 Customer-Specific Adaptation

Customer-specific adaptation of equipment to the customer environment is not included in the delivery or in IVAeris's equipment installation. The Customer accepts that it may be necessary to dismantle cabinets or cover panels around the equipment, and that rebuilding these is not part of the installation performed by IVAeris.

Structural modification work to the installation site or ventilation ducts is likewise not part of equipment installation. IVAeris may order such work from a subcontractor when separately agreed in writing at the prices in its then-current price list.

The Customer is responsible for all dismantling, construction or finishing work not expressly included in the delivery or agreement.

3.8 Acceptance Inspection

Unless a separate acceptance test has been agreed in writing, the Customer must carry out an acceptance inspection of the equipment within seven (7) days of the Delivery Date. The Customer must notify IVAeris in writing without delay of any defects or deficiencies observed at delivery.

The delivery of equipment and/or work is considered accepted:

• when the Customer has expressly accepted the delivery;

• when IVAeris has corrected defects and deficiencies reported in writing by the Customer during the acceptance inspection or acceptance test that prevent acceptance;

• if the Customer does not make a written observation of a defect or deficiency preventing acceptance within seven (7) days of the Delivery Date; or

• if the Customer puts the equipment into use.

If the Customer fails to carry out the inspection within the deadline, the delivery and work are considered accepted in all respects. For consumer customers, the 7-day acceptance period applies only to immediately observable defects. The consumer's right to complain about latent defects is determined by the Consumer Protection Act.

3.8a Documentation of Initial Condition

IVAeris Oy documents the condition of the site before work begins through photography, measurement results and written observations. This documentation constitutes the description of the initial condition on which IVAeris Oy's liabilities and warranties are based.

The Customer has seven (7) days from the Delivery Date to dispute the content of the documentation in writing. If no written dispute is submitted within the deadline, the documentation is considered accepted as the description of the initial condition in all respects.

If defects, deficiencies or deviations observable before work begins are identified at the site that do not fall within the agreed scope of IVAeris Oy's work, IVAeris Oy is not liable for correcting them or for any consequences arising later. For consumer customers, the provisions of the Consumer Protection Act on complaints regarding latent defects apply to the extent required by law.

3.9 Correction of Defects

Deficiencies or defects that do not materially impair the use of the equipment do not prevent acceptance of the delivery, but IVAeris is obliged to correct them without undue delay under the warranty.

Features that are part of the normal operation of the equipment but which the Customer finds undesirable are not covered by the warranty.

It is the Customer's responsibility to familiarise themselves with the equipment's features, user manual and operation before purchase. If the Customer has not read the user manual and the equipment operates in accordance with the manufacturer's specifications, this does not constitute grounds for a warranty repair or complaint.

Defects repaired under warranty or a complaint are covered only to the extent they constitute a manufacturing defect, installer error or deficiency within the scope of the warranty terms.

3.10 Use of Third Parties

IVAeris has the right to use appropriately trained third parties in providing services, maintenance and equipment installation, and, under supervision, trainees from partner schools (Taitotalo, Omnia and Stadin Ammattiopisto).

IVAeris Oy is responsible for all work by subcontractors and trainees as if it were its own, unless otherwise agreed in writing.

4. Prices and Payment Terms

4.1 General

Where no price for a service or piece of equipment has been agreed in the contract or otherwise, the price shall be in accordance with IVAeris's current price list.

If a service is performed at the Customer's request outside the scope of the principal service, IVAeris has the right to charge supplements in accordance with its current price list.

IVAeris also has the right to charge additional costs arising from incorrect information provided by the Customer or other reasons attributable to the Customer.

IVAeris has the right to charge the Customer additional fees such as travel costs, overtime supplements or other service charges for services performed at the Customer's request outside normal working hours or as work not included in the agreement.

Additional and variation work is only performed on a written order unless otherwise agreed.

A discount granted, a campaign price or a customer-specific special price is solely a commercial gesture and does not alter the agreed written scope of work. The content, scope and applicability of the work is determined solely by the written order, offer or order confirmation. If the Customer considers that a particular work step or location is included in the order, the Customer must demonstrate this in writing before work begins. Granting a discount does not under any circumstances extend the scope of work to cover work or locations not expressly agreed in writing.

4.1a Verbal Orders and Billing Basis

If the Customer orders work or a service by phone or other verbal means, IVAeris Oy will send the Customer a written order confirmation by email or other written channel before work begins, or immediately thereafter if the work has been started before the confirmation was sent due to urgency. The confirmation includes a description of the agreed work and the billing basis.

If the Customer does not dispute the content of the order confirmation in writing before work begins or within twenty-four (24) hours of receiving it, the confirmation is considered accepted and the billing basis becomes binding.

If no written price or billing agreement has been made before work begins, billing takes place automatically in accordance with IVAeris Oy's current price list. The Customer may not subsequently dispute the billing basis solely on the grounds that no prior written agreement was made, provided IVAeris Oy has acted in accordance with its current price list.

4.2 Billing for Fixed-Price Services

Fixed-price services are invoiced in advance unless otherwise agreed. If payment has not been made by the time of the scheduled service, the service will not be started.

The duration and content of IVAeris Oy's fixed-price services are stated separately. If a service takes longer than stated in the service description, the excess hours are billed at the current hourly rate.

The hourly rate is calculated per technician per hour, rounded up to the next full hour. The billing basis is always stated in the order confirmation.

If materials needed for the service are procured through IVAeris Oy, these material costs are invoiced after the service has been completed. Material prices are based on the list prices of wholesalers (Onninen, Ahlsell or Dahl) plus VAT.

4.3 Billing for Hourly-Rate Services

Hourly-rate services are invoiced in accordance with the agreed payment schedule, or if no schedule has been agreed, upon completion of the work.

The hourly rate is calculated per technician per hour, rounded up to the next full hour. The billing basis is always stated in the order confirmation.

Billing for hourly work begins from the moment the technician leaves the office and ends upon their return.

The hourly charge is an all-inclusive service price covering all time necessarily associated with the service, including transit time, supervisory tasks, customer communications and statutory rest breaks. All unavoidable costs of service delivery are included in the hourly rate.

In the Helsinki Metropolitan Area a fixed service travel charge applies; elsewhere a per-kilometre charge is added to the fixed travel charge for the distance from the office to the site and back.

Work agreed on an hourly basis is also subject to site costs in accordance with the current price list. The minimum charge for hourly work is always two hours, and urgent work carries a 100% surcharge.

Billable working time includes all work required for the service regardless of whether it is carried out at the Customer's site or at IVAeris Oy's office. This includes, among other things, measurement and inspection work on site, plugging and sealing work, calculation and sizing work, drafting of records and reports, and other work directly related to the service. Reporting and documentation are not separate or additional activities but an integral part of professionally performed service, and are billed on an hourly basis in accordance with the current price list.

4.4 Value Added Tax and Other Public Charges; Payment Terms

Unless otherwise agreed in writing, the prices stated in the agreement include all public charges imposed by authorities in force on the date the agreement is signed, with the exception of value added tax.

If the amount or basis of public charges imposed by authorities changes as a result of legislative amendments or changes in tax practice, the prices of equipment and services will change accordingly.

Payment terms are fourteen (14) days net from the invoice date; late payment interest is as provided under the Interest Act. IVAeris has the right to charge reminder and collection costs arising from an unpaid instalment.

If the Customer's payment is overdue by more than thirty (30) days from the due date, IVAeris has the right to suspend its performance without liability until the Customer has paid all overdue amounts.

5. Ownership, Right of Use and Risk

5.1 Ownership

Ownership of equipment purchased by the Customer transfers to the Customer only when the full purchase price has been paid in full to IVAeris Oy. Until payment is made, ownership remains with IVAeris Oy, which has the right to repossess the equipment without liability if the Customer materially fails to comply with the payment terms.

5.2 Risk

Risk for the equipment passes to the Customer when the equipment has been handed over to the Customer, delivered to the Customer's premises, installed, or otherwise transferred to the Customer's control in the agreed manner. Thereafter the Customer bears all risk of damage, loss, destruction or other risk.

5.3 Customer's Obligations

Until IVAeris Oy has received full payment for the equipment:

• The Customer must not move the equipment or allow it to be moved from its installation location without IVAeris Oy's written permission;

• The Customer must keep the equipment in good condition, insure it for its full value, and bear all risk of damage that may occur to it;

• The Customer must not make modifications to the equipment without IVAeris Oy's written consent and must permit IVAeris Oy's representative to inspect the equipment when necessary.

The Customer is responsible for ensuring that the equipment is properly maintained and protected until ownership has transferred.

If the equipment is moved, modified or damaged before ownership has transferred, IVAeris Oy has the right to claim compensation for the resulting damage or costs.

6. Warranties and Complaints

6.1 General Warranties

Unless otherwise agreed in writing, IVAeris Oy applies the equipment manufacturer's warranty. Warranty periods and terms for services and equipment are determined by the terms given by the relevant manufacturer and/or importer. The warranty covers only equipment in its original and unmodified condition. The warranty is valid for the original customer only and is not transferable unless otherwise agreed in writing.

All installation, cleaning, sweeping, maintenance, inspection and consulting work, as well as equipment and spare parts, are covered by the warranty only if the work or delivery has been carried out in accordance with Finnish laws and regulations in force, SFS standards, the RT construction guidance library (e.g. RYL), the HVAC guidance library and the manufacturer's instructions, as well as generally accepted professional practice in the HVAC industry.

No warranty or credit is granted solely on the basis of the Customer's subjective dissatisfaction, expectations or personal preferences if the work meets the objective requirements stated above.

6.1a Complaint Obligation and Loss of Rights Due to Delay

The Customer must complain about an observed defect or deficiency without delay upon discovering it or when they should reasonably have discovered it. If the Customer knew or should have known of a defect and has not complained within a reasonable time, the Customer loses the right to invoke that defect.

For B2B customers the reasonable complaint period is no more than fourteen (14) days from discovery of the defect. A consumer customer's right to complain is determined by the Consumer Protection Act, and this clause does not restrict the consumer's statutory rights regarding latent defects or defects that emerge later.

6.2 Equipment Warranty

Unless otherwise agreed in writing, the warranty period is twenty-four (24) months from the date the service is performed or from the Delivery Date of the equipment, or for the warranty period given by the equipment manufacturer. The mandatory provisions of the Consumer Protection Act apply to a consumer customer's warranty and liability for defects to the extent required by law.

IVAeris Oy will arrange the repair of a defective piece of equipment, part or component about which the Customer has notified IVAeris in writing without delay during the warranty period. The Customer must report and, if necessary, demonstrate how the defect manifests itself.

Equipment warranty repairs are carried out primarily at the Customer's premises in Finland unless otherwise agreed or required by the equipment manufacturer. To enable repair, the Customer must make the equipment available to IVAeris Oy or the manufacturer for the necessary period during normal working hours. Repair may also be effected by delivering a replacement unit to the Customer.

If the warranty repair is carried out at IVAeris Oy's premises, the Customer must deliver the equipment there for repair. IVAeris Oy pays the costs of delivering and returning the equipment for warranty repair if the defect is covered by the warranty.

6.3 Spare Parts Warranty

Unless otherwise agreed in writing, the warranty period is six (6) months from the Delivery Date of the spare part. For consumer customers, the defect liability provisions of the Consumer Protection Act apply.

IVAeris Oy or the equipment manufacturer will repair a defective spare part or component about which the Customer has notified IVAeris in writing without delay during the warranty period. The Customer must report and, if necessary, demonstrate how the defect manifests itself.

Spare part warranty repairs are carried out primarily at the Customer's premises in Finland unless otherwise agreed. Repair may also be effected by delivering a replacement spare part to the Customer. If the warranty repair is carried out at IVAeris Oy's premises, the Customer must deliver the spare part there. IVAeris Oy pays the costs of delivering and returning the spare part for warranty repair if the defect is covered by the warranty.

6.4 Installation Warranty

IVAeris Oy provides a six (6) month warranty on installation work from the handover date unless otherwise agreed in writing or a longer liability period is required by law. For consumer customers, the defect liability provisions of the Consumer Protection Act apply to the extent required by law.

The warranty covers only the technical installation quality of the work and the achievement of the agreed installation result. The warranty does not cover manufacturing defects in the equipment or damage caused by incorrect use of the equipment or system, failure to carry out maintenance, use contrary to instructions, external damage or structural deficiencies in the Customer's premises.

The warranty also does not cover deficiencies arising from installation conditions that are the Customer's responsibility (e.g. defects caused by moisture, dust or other harmful substances).

Installation warranty repairs are carried out primarily by IVAeris Oy and require the Customer to report the defect immediately upon discovery and to give IVAeris Oy the opportunity to correct it within a reasonable time. All modifications or repairs made by the Customer and consequences of inadequate installation readiness are excluded from the warranty.

Installation work is always carried out in accordance with applicable SFS standards, HVAC guidelines, RT guidelines and manufacturer requirements. The accepted quality of the work is assessed against these regulations and good HVAC industry practice, not against the Customer's subjective expectations. If the work meets all regulations and guidelines, dissatisfaction alone does not entitle the Customer to a warranty repair.

6.4a Subsequent Work by Third Parties at the Same Site

If, after IVAeris Oy has completed its work, the Customer has ordered or permitted a third party — such as another contractor, supplier or other party — to work in the same duct system, plant room, technical space or other area within the scope of IVAeris Oy's work, IVAeris Oy's warranty and liability lapse to the extent that the third party's actions may have affected IVAeris Oy's original work performance.

Lapsing of liability requires IVAeris Oy to demonstrate a connection between the third party's actions and the observed defect or deficiency. For consumer customers, the mandatory provisions of the Consumer Protection Act nonetheless apply.

6.5 Warranty for Cleaning, Sweeping and Maintenance Work

IVAeris Oy is responsible for ensuring that cleaning, sweeping and maintenance work is carried out in accordance with the current guidelines, regulations and good professional practice. The warranty covers the technical execution of the work and the provision of a report on the measures taken to the client.

The warranty does not, however, cover subsequent soiling of the duct system, emergence of structural defects, latent damage or problems arising from the characteristics of the system (e.g. original malfunction of the ventilation system or operating errors).

If damage, obstructions or deviations are found in the system during the work that prevent full or partial completion, IVAeris Oy will inform the Customer without delay and carry out the work as far as possible, after which the work is considered completed to the best possible standard without any obligation to provide a credit.

Cleaning, sweeping and maintenance work is carried out in accordance with the HVAC guidance library, the RT construction guidance library, Finnish building regulations and applicable standards. Dissatisfaction following the work does not constitute warranty grounds if the work is documented as having been carried out in accordance with regulations and guidelines.

6.6 Warranty for Inspection and Measurement

A warranty for inspection and measurement services is granted only for the correctness of the measurement or inspection carried out under the conditions prevailing at the time. IVAeris Oy is responsible for ensuring that measurements and inspections are carried out in accordance with applicable standards and professional practice.

The warranty does not, however, cover subsequent changes in conditions, indirect damage arising from use of the measurement result, or latent deficiencies in the system that cannot be established by conventional means. Measurement and inspection reports are provided to the client without separate liability for how the client interprets the results.

Measurements and inspections are always based on Finnish regulatory requirements, SFS and HVAC standards and the RT guidance library. Subsequent customer dissatisfaction or interpretation does not constitute warranty grounds if the measurement was carried out in accordance with standards and industry practice.

6.7 Warranty for Consulting and Expert Services

IVAeris Oy warrants that consulting and expert services are carried out carefully and in accordance with the information and assignment provided by the Customer. The warranty covers only the justification of the consulting and recommendations given in accordance with current legislation, regulations and general professional competence.

The warranty for consulting and advice does not cover the client's decisions, implementation solutions or subsequently emerging circumstances not known to IVAeris Oy at the time of the assignment. The client is responsible for all measures taken on the basis of the consulting. IVAeris Oy's liability for consulting services is limited to the price paid for the service.

Consulting and expert services are always based on current Finnish legislation, HVAC industry guidelines and generally accepted professional practice. If the recommendations given meet these criteria, dissatisfaction alone does not entitle the Customer to a complaint.

6.8 General Warranty Exclusions

The warranty, and maintenance or upkeep services provided during or after the warranty period, do not cover:

• normal wear and tear of the equipment or its consumables,

• modification, refurbishment or relocation of the equipment,

• repair of defects or errors or replacement of a spare part caused by:

• an external cause such as an accident, electrical or air conditioning fault, lightning damage, fire or water damage;

• incorrect use, negligence or failure to maintain the equipment, or failure to follow operating, maintenance or cleaning instructions;

• use of equipment, original filters or spare parts not supplied by IVAeris Oy, or modification or repair of the equipment by a party other than IVAeris Oy or its authorised representative — provided that such action contributed to the observed defect;

• failure to follow the equipment's operating instructions, installation requirements or environmental requirements.

The warranty does not cover indirect damage or damage that arises gradually, latently or over time, unless the matter concerns an installation or work defect identified and complained about during the warranty period.

The warranty does not under any circumstances cover subjective feelings or expectations if the work or delivery meets the objective quality requirements of the industry and legislation stated above.

6.9 Costs Outside the Warranty

If it is established that the defect or error reported by the Customer is not covered by the warranty, IVAeris Oy has the right to charge for searching for and locating the defect or error in accordance with its current price list.

IVAeris Oy also has the right to charge the Customer for correcting a defect or error not covered by the warranty if this has been separately agreed with the Customer.

6.10 Limitation of Liability

IVAeris Oy's liability for defects and errors in equipment, services, installation, cleaning, inspection and consulting is limited to fulfilment of the warranty terms stated above. After the warranty expires, IVAeris Oy's liability is limited to obligations under any applicable maintenance or upkeep agreement.

IVAeris Oy's maximum liability is always limited to the amount paid for the service or equipment. IVAeris Oy is not liable for indirect damage such as loss of earnings, loss of profit, third-party claims or damage arising gradually or over time, unless mandatory legislation provides otherwise. This limitation of liability does not apply to damage caused by the gross negligence or intentional conduct of IVAeris Oy's personnel. The liability insurance covers only sudden and unforeseeable damage in accordance with the insurance terms.

7. Impediment, Force Majeure and Release from Liability

7.1 Force Majeure

IVAeris Oy is not liable for delays, failure to fulfil delivery or contractual obligations, or damage resulting from a sudden and exceptional impediment (force majeure) that is beyond IVAeris Oy's control, could not reasonably have been foreseen at the time of contracting, and whose consequences could not reasonably have been avoided or overcome.

Force majeure events include, among others, natural disasters, exceptional weather conditions, war, rebellion, acts of authorities, epidemics/pandemics (e.g. COVID-19), traffic disruptions, fire, industrial action, strike, boycott, supply chain disruptions, exceptional illness, third-party insolvency, IT system problems, technical failure, sabotage and any other similar impediment, regardless of whether it affects IVAeris Oy, a subcontractor or another party responsible for fulfilling the agreement.

In the event of force majeure, the affected party has the right to postpone delivery or work or service performance until the impediment has been removed. The party whose performance is affected must notify the other party of the impediment and its estimated duration without delay. During force majeure a delay does not entitle either party to damages, termination of the agreement or other sanctions.

7.2 Subcontractor Force Majeure

If a subcontractor of IVAeris Oy is affected by a force majeure event that prevents the subcontracted work from being carried out as agreed and no substitute performance is available on reasonable terms, this also releases IVAeris Oy from its contractual obligations for a corresponding period.

7.3 Epidemics and Pandemics (e.g. COVID-19)

Official orders, travel and movement restrictions, workforce quarantines, supply chain disruptions, problems with the availability of supplies, raw materials or equipment, and sudden and significant price increases caused by an epidemic, pandemic or comparable health threat are considered force majeure.

If COVID-19 or a comparable situation causes IVAeris Oy unreasonable delays, impediments, difficulties or additional costs, IVAeris Oy is not liable for delays or their consequences for as long as the impediment persists. This release from liability also covers all indirect and consequential effects, such as schedule changes, price and resource fluctuations, workforce absences and logistics problems.

8. Cookies and Data Protection

IVAeris Oy's website uses cookies to improve and speed up the visitor experience and to develop the functionality and usability of the site. Users may block the use of cookies in their browser settings, but this may mean that not all website functions can be guaranteed.

Personal data is processed in accordance with data protection legislation and IVAeris Oy's privacy notice. The privacy notice is available at www.aeris.fi. Customers have the right to view and correct their personal data and to prohibit its use for direct marketing.

9. Cancellation Terms (Consumer Customers)

A consumer customer has the statutory right under the Consumer Protection Act to cancel an order within fourteen (14) days of receiving the order confirmation. Cancellation must be made by phone or email to the supplier's contact person.

The right of cancellation lapses when the work has been started at the consumer's express request before the cancellation period has expired; in that case, only the work steps completed and costs incurred up to that point are charged.

If the customer cancels later than 24 hours before the agreed start of work and the work has not yet been started, IVAeris Oy has the right to invoice for actual costs arising from the cancellation, such as the installer's reserved time, up to a maximum of EUR 250 (incl. VAT 25.5%) per unit/work site.

Business customer orders are always binding unless otherwise agreed in writing.

10. Dispute Resolution

Any disputes arising from the agreement shall be resolved primarily through negotiation.

If agreement cannot be reached, YSE 1998 general conditions of contract (General Conditions for Building Contracts) serve as the dispute resolution framework.

A consumer customer has the right to refer disputes to the Consumer Disputes Board or the European Commission's Online Dispute Resolution platform.

Otherwise disputes are resolved primarily in the Espoo District Court. However, a consumer customer always has the right to bring an action in the district court of their own place of domicile.

11. Validity of Terms and Conditions

These terms and conditions are valid indefinitely and supersede all previously published and separately agreed general terms and conditions.

IVAeris Oy reserves the right to amend the terms unilaterally. Amendments take effect immediately for new orders. Each order is governed by the terms in force at the time of ordering. The current terms are always published at www.aeris.fi.

Changes required by law take effect immediately unless the law provides otherwise.

12. Limitation of Liability for Damages and Insurance Cover

IVAeris Oy's liability for damages is limited to a maximum of the purchase price of the service or equipment delivered, and does not cover indirect damage (such as loss of earnings, loss of profit, damage caused to third parties or other consequential costs) unless mandatory legislation provides otherwise.

IVAeris Oy's liability insurance covers only sudden and unforeseeable damage in accordance with the insurance terms. Gradually arising, latent or long-term damage (such as moisture damage, mould damage, accumulation of dust in structures) is not covered by the liability insurance unless the damage results from a single sudden event. Customers are themselves responsible for any damage that does not meet the conditions of the insurance terms.

13. Data Protection

All processing of personal data takes place in accordance with the EU General Data Protection Regulation (GDPR, 2016/679). The privacy notice is available at www.aeris.fi.

14. Subcontracting and Trainees

IVAeris Oy may use appropriately trained third parties and, under supervision, trainees from partner schools (Taitotalo, Omnia, Stadin Ammattiopisto) in providing services, maintenance and installations. IVAeris Oy is responsible for their work as if it were its own.

15. Termination of Agreement

Either party may terminate the agreement on grounds of a material breach of contract if the breach is not remedied within a reasonable time despite a written notice.
