We were having problems with our commercial building HVAC system, heating and cooling. Our old vendor assured us that our problem was at the furnace……”you need a new blower or you need a new controller and if that won’t fix it we’ll need to replace the whole unit!” Our symptom was low air flow at the registers in the offices and before I went to that expense I wanted a second opinion. Comfort Air and Heating came in and diagnosed the problem. Turns out the problems were all with our duct work system, kinks, disconnected ducting, dampers not working properly. Now everything is working wonderfully for us, we have had hot days and not gotten over 72-73 degrees in our offices. Thanks for a great job!
