Why Acex
I’m Gennadi Biriouk. I have worked in HVAC since 1997 — close to 30 years of repairing, installing, and taking care of home heating and cooling systems.
When you message Acex, you reach me. I come to your home, look at the system, and explain what I find in plain language. Then we decide what to do together. Estimates are always free.
Our mascot
