"No findings, no solution, no explanation… collected the fee… the issue is still there. I had Triad Mechanical Company for our HVAC issue that the outdoor unit is not running. I told Paul, the assigned technician, that we had tried resetting the power to the outdoor unit but that only brought the unit back on running for a few days before it stopped running again. I asked Paul’s help diagnose the issue for the root cause. However, when I came to the property just a few minutes later than Paul, he told me that he had done his work already, well, by simply resetting the power to the unit! (although I told him that we already tried that but it didn’t work!)… He didn’t have the patience to explain to me what diagnosis he had done (within that a few minutes) and he didn’t even bother to come off his truck to show me but saying “go ask your tenant”. He collected the fee and left. I will never trust nor use Triad Mechanical Company again!"

"The guys from Economy Heating and Air helped us with a emergency situation with our old furnace, including a replacement of the unit with a new heat pump. They were the only company I called that could come out immediately to look at the problem. Overall, I felt very comfortable with their HVAC knowledge. They answered all of my questions and left the jobsite clean after their work. I highly recommend."

"I highly recommend this business. The technician, Pierer, and his colleague were true professionals and incredibly courteous. Even though I was their last appointment of the night, they went above and beyond to source a replacement part that wasn't stocked on their truck. I truly appreciate their dedication to getting our HVAC unit running late in the evening. Thanks to them, my family was able to sleep comfortably with the heat restored."
