This family-owned and -operated HVAC service has responded promptly to calls in the Greater Metro Atlanta area for more than 20 years, offering the best value from certified technicians.

"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!"

"We had a full HVAC system replacement for both floors of our home, and we are truly grateful for the service we received from Weather Masters. From the beginning, the owner was understanding of our situation and worked with us on the pricing in a way that no other company was willing to do. He adjusted the cost significantly — almost as if we were paying cash — which meant so much to our family during a stressful time. The installation was done professionally and efficiently, and the team was respectful and organized throughout the entire process. It’s rare to find a company that combines professionalism with genuine care for their customers. We truly appreciate Weather Masters and highly recommend them. Thank you again for helping our family."

"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."

"My appointment was on Monday 1/5/2026 to fix a leaky shower faucet that had continuous running water. Jordan Benavides responded and came to the job ill-prepared and without the proper tools to complete the work. He went to Home Depot, came back and still didn't do anything. He had one excuse after another and spent more time at his truck than on the job. I have him on videotape going to his truck 15 times, even sitting idly one time for 15 minutes. He charged $530 for the job and tried to price-gouge me for more business. After 2 hours of him stalling, I called dispatch and sent him on his merry way. I was left with a leaky faucet and a damaged shower handle which was working before. I called another company to fix the handle and solve my problem. If Jordan is indicative of the caliber of technicians Casteel employs or subcontracts, I will not be doing any further business with Casteel. "
