Therma Tech installation team leader and members completed the job right on schedule. They were on time, courteous, patient in answering our questions, and kept the work area clean.

We would recommend Therma Tech to our friends and neighbors w/o hesitation.

I had an excellent experience with Henry from ThermaTech. My HVAC system stopped working properly…read moreafter another company had spent about two hours diagnosing it and quoted me more than $3,000 for a new control board, contactor, transformer, surge protector, and maintenance plan. Henry arrived, clearly explained each step of his diagnostic process, and quickly identified that the transformer and contactor were the actual issues. He completed the repair in about an hour and charged me $540 total, saving me roughly $2,500 compared with the previous quote. What impressed me most was Henry's honesty, expertise, and transparency. He did not try to upsell me or replace parts that were not needed. He took the time to explain what had failed, why the system was not powering on, and what he was doing to fix it. It is rare to find an HVAC company that combines strong technical knowledge with fair pricing and integrity. I would absolutely recommend ThermaTech to anyone looking for an honest and skilled HVAC professional.

Dennis Sushko and Slava (Comfort Advisor) came to my house to walk the site, review the scope of work, and thoroughly address all of my concerns. Jessica in the permit department was fantastic with scheduling--she was incredibly proactive, kept me updated every step of the way, and even helped fill out the paperwork for local rebates. On installation day, Tony and Adam showed up right on time. Both were extremely professional. Because of tight space constraints on my wall, they had to work extra hours to complete the installation in a single day so I wouldn't be left without power overnight. They also did a spotless job cleaning up the workspace before leaving. I strongly recommend Freon Service to anyone looking for HVAC work or an electrical panel upgrade!

So much so that it gave me the confidence to buy my first home without A/C because I knew I could just call Calvey. A few years later I did just that. Damn, it's been a couple of months now and I've been able to control the climate of my entire house from my phone, optimizing the temperature and sometimes making it as low as 66F to just enjoy the air being crisp. The install has been fantastic quality and the crew listened to everything I wanted every step of the way. They mounted rat spikes where I wanted, they put the lines and the units exactly where I asked and I've had no issues at all. I truly believe with home price comparisons in my area that I made money off of the install because it increased my home value.

He worked around my schedule, kept things stress-free, and was friendly and easy to talk to from start to finish.
