"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!"

Premier HVAC Mechanical Corporation is a second-generation, family-owned HVAC company serving Metro Atlanta with over 35 years of trusted experience. Led by owner Steve West—a highly seasoned custom home builder and HVAC professional—we bring a rare depth of building-science knowledge to every service and installation. We specialize in residential and light commercial heating, air conditioning, and indoor air quality, and proudly service all makes and models, including Amana, American Standard, Bryant, Carrier, Goodman, Heil, Lennox, Rheem, Ruud, Trane, and Whirlpool. Our Comfort Maintenance Program (CMP) offers priority service and savings, and we focus on honest guidance—not pushy sales. For us, it’s personal—from the first call on, we treat our customers like family, take a sincere interest in your comfort, and work hard to earn your trust.”

"Their tech came to our townhome for the HVAC heat pump issue, spent more than 3 hours diagnosing the issue and then told us that we had to replace the zoning control board and the thermostat at $1400 in total. We were charged $390.00 for the diagnosis. We were not convinced by what he told us. Then, we called another HVAC contractor from different company to look at the issue. He was able to pin point the issue with the unit in 15 minutes and fixed it by refilling refrigerant at around $300! What a difference! I will never trust and use Premier HVAC Mechanical Corporation again!"
