    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.

    Henry is the reason why Therma Tech supersedes all the other HVAC businesses. We have an ancient…read morefurnace-condenser system. We had no idea when it was last serviced or if it had ever been serviced at all. Henry gave us a very fair and competitive price for a tune up. Upon Henry's arrival, he was friendly and professional. He opened the furnace and showed us the burner. He explained it was in great condition considering the age of the unit and it didn't need servicing; although, he did clean up around a few areas around the burner. The blower motor was slightly wobbly, and once again, he explained it was still in good shape considering its age. He proceeded to the back patio where the condenser was located. He noted the unit was very old and that particular Freon is no longer available for servicing; however, he stated the unit did not need to be replaced just yet as long as it's blowing cold. Henry indicated despite our units being way past their anticipated life expectancy, they were clean and blowing hot & cold just fine. Therefore, no servicing was recommended and he did not charge us anything. We are impressed not only by Henry's friendliness and professionalism, but also by his transparency and integrity. Many other companies would have hopped on the opportunity to upsell the service or even sway us to replace our system right away, but Henry gave us peace of mind to give us time and to save up for an inevitable replacement in the future with Therma Tech. Thank you so much, Henry! We will definitely contact you again in the future and recommend you to all our family, friends and coworkers.

    Years ago the apartment complex I lived at contracted Calvey to install mini-split A/C in the…read moreapartment I was in. The install was amazing quality! 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. My golden retriever is happy, I am 100% happy and I will see you guys again next home upgrade. :)
