Why choose IVAeris?
We are not a large organization with a hundred technicians ready to go. We are a small, selective team. We don’t take on every job, because then we couldn’t maintain our quality. But when we do take a job, we do it properly.
Often we are called in only after others have already given up. Then we don’t just solve the problem—we make sure the system works in the long term. If you want work that is done carefully, takes the time it needs, and is based on an honest analysis of what is wrong and how it should be fixed, we are the right partner. What matters most to us is that the end result works and that you can rely on it for years to come.
Completed projects
Browse our references: choose the year of completion, service, or location. Each project tells a story—not only about how we improved indoor air quality and energy efficiency, but also how we did it and how customers have been satisfied.
What our customers say
★★★★★
“I received excellent advice and help with my problem quickly. Customer service was truly knowledgeable and friendly, genuinely trying to find real help in a problem situation.”
— Mikko R.
“They contacted me immediately when I reached out and came to look at my problem on site! Other ventilation companies didn’t even respond to me. We received a quote and the price held even though the job was demanding and grew as the project progressed. When the work was done excellently, we also received a final report that is very comprehensive.”
— Arto A-W.
“We were left with a very good and high-quality impression of your work. I am especially happy with your communication, which is exceptionally good compared to most operators in a housing company environment. We knew at all times where things stood and what would happen next.”
— Jari H.
“They don’t fear challenges, but see them as a source of extra motivation. Strong recommendation!”
— Nemanja S.
“Good and professional service, the work went well and quickly on schedule!”
