Our story
Why I started AQC
Between 2015 and 2018, I worked as an HVAC technician for a local company. My job included repairs and installation of furnaces, air conditioners and ventilation ductwork for residential and some commercial clients.
During those years, I noticed that most households had HVAC equipment that was greatly oversized and improperly installed. That led to premature equipment failure and higher utility bills for homeowners. Another common problem was poor indoor air quality, which caused excessive humidity, biological growth and uneven temperatures inside the home.
In February 2018, after getting all the necessary licensing and paperwork, I established AQC Services Inc. to bring real solutions to these underlying problems in the industry.

In our old house, Ross replaced both our air conditioner and furnace. From the beginning, we were impressed by how knowledgeable, honest, and trustworthy he was. … We recently hired Ross again to replace the HVAC systems in our new house. Obviously, no one looks forward to spending money on a new furnace and air conditioner, but I genuinely felt comfortable making such a significant purchase because I knew we were working with someone we could trust.
