HVAC Service San Jose

  Its hot and these guys care!  I am so thankful for you guys going out to take care of my tenant's needs so fast given his family 2 poor dogs were not happy int his heat.  Truly appreciate your prompt response and fix!   You guys ROCK!

  My AC gave up in the middle of the heat wave. Thermal tech was incredibly responsive and had the most reasonable diagnosis rate. The owner Henry gave me the most honest diagnosis. He was knowledgeable about my unit and encouraged me to look into my warranty. It was under warranty. He even waived the diagnosis charge because he could not help me fix it. If I ever had anything to fix I would not hesitate to use them.

  Henry and his team are the best. Came over same day (during a heat wave surge) when no other companies would, and, on top, saved us over $2000 by being an honest businessman. The first technician we called to see our AC unit (from a different company) was dishonest in his assessment and tried to take advantage of the situation. Henry explained the problem and made it clear that we were given erroneous information and were getting price gauged.

Give your business to Henry. You won't regret it.

  I just had yet another exceptional experience with ThermaTech.  Henry has serviced my ancient HVAC system several times, and he is always fantastic. At a service visit last week, he said he could do another repair if I wanted (this time there was a freon leak), but at this point he felt it would be better to consider replacing my old inefficient system.  He did not pressure me into the decision -- he went over the projected costs of keeping my old system going versus installing a new one.  I decided that it made economic AND environmental sense to invest in a new HVAC system, and ultimately decided to replace the furnace as well as the A/C.   ThermaTech gave me a fair quote, and I felt 100% confident giving them the job.  

Mark and Gustavo did an exceptional job installing the new furnace and A/C today.  They were very knowledgeable and personable; arrived on time; and worked diligently throughout the day.  At the end of the day, everything was up and running perfectly, and they gave me a tutorial on the new system.  They also left my house and yard spotless, and wore booties inside the house -- another plus!   Delighted with my new A/C -- works SO much better than my old system.  

Highly recommend ThermaTech once again!

  Our AC fan died on one of the hottest days of the year.  It was during a heat wave so we assumed (correctly) that most AC repair services would be booked up.  We called between 6 and 8 places and the earliest they could get a technician out was the following week... some were saying almost two weeks.

Therma Tech responded the same day and had a technician stop by our home that evening as his last call.  Henry was great--professional, honest, and a great communicator.  He repaired our issue in less than an hour and got us up and running again.  Highly recommended!

  During a heatwave, my upstairs AC unit stops cooling.  Two other local HVAC companies didn't return my call.  I called ThermaTech and left a voicemail at 2:10pm and received a call back within 15 minutes scheduling a visit for noon the next day.  Henry arrived early and gave me a text update letting me know he was on his way.  He was knowledgeable and took the time to make sure I understood the components and my repair options.  We were lucky that it was a simple capacitor replacement but he still gave 2 options (standard replacement or replacement plus an extra component that could extend the life of the compressor).  There was no pressure to choose either option.  
I will call Henry again in April to schedule preventative maintenance that we all ignore until there's a problem.

  Every positive comment made here by others using this company is absolutely true and verified by my own experience.  My AC failed at the peak of the September 2022 heat wave...and on Friday! I called another diamond certified company but received no call back...ever!  On the other hand, Vickie, at the Therma Care office answered immediately was very polite, calm, extremely helpful in attempting to trouble shoot my problem via the phone. When it was determined that the issue required an on-site diagnosis, she managed to work in an emergency appointment which would not interfere with my preset commitment.  I received a text message as notification that the technician was in route, insuring arrival time would be at the earliest end of the window promised.  Henry quickly diagnosed the issue and gave a clear description of what was needed and the cost of repair.  I was very impressed with Henry's straight forward manner and obvious professional skill delivered with kindness and respect for the customer.  Henry and the Therma Care staff went out of their way to accommodate my need and I am immensely grateful!  I have no hesitation in employing and recommending this company to others for HVAC service.

  I would definitely recommend this business to anyone who has an issue with their A/C. I had our unit replaced by Therma Tech almost 10 yrs ago. I've had a few issues during that time but Henry (owner) was always ready and willing to take care of the issue in a timely manner and honor the warranty with no questions asked. Henry is a man of integrity and you can rely on him to do you right! I would definitely give him your business...you won't be disappointed!!Thanks again Therma Tech for your speedy repair time and honesty which is rare these days!!!

  I called ThermaTech and received a call back within 15 minutes.  They scheduled a visit for the next day and replaced the capacitor in 15 minutes. Henry took the time to explain what he was doing and made sure I understood the components involved.  He was efficient and did not pressure me to make a decision.  Ten days after his visit (and successful repair of my upstairs AC unit),  my downstairs unit stopped working.  I called ThermaTech on Monday morning and received a call back within 10 minutes.  Henry provides reliable service!  I'll call him again!

  Professional, knowledgeable and friendly service with an owner who stands by his company's work. After a recent heatwave, the fan on my HVAC system would not turn off. Henry determined that I had a bad controller board and was back to replace it a couple of days later. After he completed the work, that night I noticed that the fan would not stay on (yes! the exact opposite of the original issue). It would run for about 2~3 minutes, then shutoff. I texted Henry at 8 PM and he immediately texted me back. I was honestly not expecting to get a response until the next day at the earliest. He patiently worked with me for over an hour as we tried to debug the issue, but he eventually concluded that he needed to come back. Henry was back at the house early the next morning and he discovered that the capacitor on the fan motor had failed. It was an problem unrelated to the original issue, so it was not an oversight on his part. So, clearly not a "smooth" service, but these things happen. However, I was most impressed and pleased with the responsiveness that I got from Henry. It's clear to me that he has professional integrity. I would highly recommend Therma Tech to anyone looking for HVAC service.
