We needed to replace our 35 year old AC unit that was on its last leg. We went through quite a few…read moredifferent estimates to migrate to a heat pump. Fuse came in significantly lower priced than everyone for a superior system. We wanted to add an additional vent on the main floor, and some dampers for a few of the vents and everything went like butter. Lex and Maxat were the nicest people, arrived on time, left at 6pm each day leaving the house clean. It was a 3 day install and they finished on the third day. Beyond what they needed to do, Lex walked through things that would be checked by the inspectors even on work they didn't do (GFCI plugs close to where the old unit was), and walked me through why they did some of the things they did because I was curious. We're 3 days in so far, but the installation experience was great, and the daikin system is cooling the house great (and I can already see from the energy monitoring systems we have, it's so much more efficient!).

Since we have solar installed on our roof, we opted for the Carrier heat pumps and new air handlers which don't use natural gas for heat.

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. :)

These guys may be ok, but I'll never know and I'll never call them again because they're very unprofessional. They misrepresent 'free estimates'... liars. Find someone else is my recommendation! Bad service, zero communication. FAIL.

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.

When the AC unit in our daughter's house started leaking, she called a company she saw in commercials. Their quote was astronomical and i could tell there was som BS going on. We called David to come take a look. Of course there was an out of season heat wave and he was very busy but was able to come out in just a couple days. He was able to repair the system rather than replace it and for a fraction of what the other company wanted. He even was bantering with the grandkid while working. He is a life saver. Prompt, professional, knowledgeable and not trying to sell you something you don't need. Thank you David!!!

He said he'd help me with my existing cooling system that uses Freon and then a few days later told me he won't work on anything with Freon after agreeing to come next week. I tried to patiently explain to him that existing units were fine and could be serviced until 2030 in California and he started mocking me and telling me to do the job myself because I know it all. He doesn't know anything about state law and I patiently tried to educate him, since he didn't attend law school and was completely incorrect. I cited the law so he would know, but he lost it. Obviously, this "grumpy" doesn't want any new business and will probably not show up to give you a quote. He stated a nasty message exchange with me and probably needs a number of psychotropic medications and therapy. If people want to threaten me, they don't want new business. What irritates me is that I tried to help him so he would understand and was very patient. This business should be renamed "Grumpy Rage" HVAC.
