HVAC Service San Jose

  Therma Tech is the most reliable HAVC I have consulted. Henry came for free quote of a brand new AC almost immediately after we texted him. He checked the environment and current facilities and then explained his professional thoughts about the project, what must to do and, what better to do, what optional to do and told us all processes of city permit, which means quote includes city permit and HERS testing. We have consulted more than three HVAC companies and Henry is the most honest and professional one so that we referred him to our friends even our project was not finished. Our new AC project should be very simple to install in the very beginning, however, it took more time than our expectation to get the city permit because of covid and our old outdated furnace infrastructure. Henry, his team, and his staffs were all patient and proactive to follow up every defects that city inspector pointed out (all about furnace rather than AC.) Thank god we have Therma tech. Strongly recommend!

  I called to see if I could get a HVAC maintenance person to come out and they were booked a week out. Vickie who answered the phone took me through a list of questions to see if there was something I could do on my end to troubleshoot the problem. After she exhausted the list she asked me for my number and said she would call within an hour to see if there was anything she could do. She called me bach within 15 minutes and said she was able to get Henry (owner of co.) To come out within 2-3 hrs.. When Henry showed up he was wearing a mask and gloves. Henry asked me a few questions, went around the house into the basement to complete a diagnostic test. He discovered the issue, told me the cost for the part and told me I could get it cheaper and how much I would save. I told him to go ahead and fix our HVAC. Henry was very efficient (entire job 15 mins.), knowledgeable, and professional.
He also looked at the entire unit and reviewed some additional items, up to including the age of our HVAC, how long they last, and the cost of a replacement.
I highly recommend Therma Tech.

  Yesterday my AC/heater started behaving all crazy, the fan would run continuously even after the thermostat turned off. I reached out to Therma Tech and was quickly set up with an 8-10am window for the next morning. Henry arrived this morning, well within the window, after an update came over text message to track his arrival time, a very neat feature. He proceeded to fix the issue within 2mins of being on site (there was a sneaky reset switch inside that had flipped) and wouldn't even take my money for the fix!

To see this kind of generosity in these hard times really warmed my heart and I thank Henry for keeping my family warm during these cold months! Thank you for being a great human being and and giving exemplary service to your customers! I cannot recommend Therma Tech enough!

  I called and got an appointment for the sa.e day. Techinican showed up on time. I got a text with ETA. Worked quickly and safely to diagnose problem with furnace. Would use Therma Tech again.

  I've used these folks several times, and their service is always great. One time they came out, looked at my system, and said I didn't need anything. No change!  How honest is that. Highly recommended.

  When our heating stopped working in December, I called several HVAC repair companies. Most did not call us back, and many of them did not have availability for several weeks. Therma Tech was the exception. Therma Tech responded quickly, and was able to come out that same day! They were prompt, professional, competitively priced, and fixed our issue quickly. We will definitely be using them again. Thank you!

  They showed up on time, found the problem quickly and had our heater up and running in less than a half hour. This was a 2nd diagnosis as another company looked at it 4 days earlier and said to not use it until they replaced a part that wasn't due to arrive until after Christmas. Being 53 degrees in the house we decided to get a second opinion and Therma tech came out within a few days of calling. Will definitely be contacting Therma Tech with any other problems or when it's time to replace our  current unit. We would highly recommend using them from this experience.

  I was able to get a same day appointment for service on our heater. Henry Elia was able to stop by sooner than the afternoon appointment time, so they called and verified the soon time was okay. Henry found the problem quickly and then offered repair options. He suggested the option that was the least expensive, but still effective, even though it meant a return visit with purchased parts would not be needed. Bottom line is that he recommended a solution that was a good choice for the customer but meant less money for him and the company.

I'm very impressed with this customer first approach and the honesty that is required to provide that type of service.

  My heater went out and they were able to come out and fix it quickly. I appreciated that they applied the cost of the inspection as a credit to the repairs.

  Henri and his team were quite professional. Quote was close to the lowest we got, while work quality, punctuality, and customer service has been just fantastic.

We had them install a three headed mini-split system for us about 6 months ago, and the system has been working flawlessly.
