Therma Tech is my repeat HVAC company I have zeroed in on after experiencing many other HVAC companies from 1-2 person outfit to nuch larger. I started with them with troubleshooting an old furnace in our first home. They fixed and charged small amount to my pleasant surprise. Next I used their service at my condo rental and they fixed in less than $100 when another company was clueless and suggesting major replacements. Then while shopping for extension of existing heat pump duct system, they came in very competitive in pricing and actually the system performs better than how the other company (another outfit well reviewed on Yelp) had installed it 10 years ago. So I trust Henry and his entire staff with any job from super small to entire systems. Every person we have dealt with are absolutely phenomenal. And no, I am not compensated in any way to write this. read more

Replacement of evaporator coil to prevent leak through secondary outlet I would like to wholeheartedly acknowledge the outstanding job done by Therma Tech. The estimator Henry was very thorough in his analysis and prioritizes my needs as a customer and proposed an elegant, cost effective solution The implementation team executed the installation with precision, skill and efficiency. I wish the Therma Tech team much success in the future. read more

Therma Tech upgraded my furnace from a single unit gas furnace to a two floor heat pump system about 4 months ago. My desires were for a quieter system and one that could fix the large temperature extreme between my first and second floor. Therma Tech did an excellent job in both areas and gave me the best price by far over all their competitors. I am extremely happy with the results and love my new system. The job involved removing my existing gas furnace and associated AC. They added a heat pump compressor outside and separate air handlers for both the first and second floors (one in place of the old furnace and one in the attic). The system is significantly quieter and I really enjoy the independent control of temperature for each floor. As a bonus powering the heat pump takes significantly less energy than before, and the energy is provided by my solar system. Lar, their sales engineer, spent a significant amount of time up front with me outlining options and trade offs. And he was there thru the entire installation process, in case I had any questions or concerns. The installers were a great crew. Very smart. Extremely courteous. Proactive in making sure I knew what they would be doing and when. And they kept everything clean after each day was over. Their customer support group is also as good as any I've seen. They were quick and responsive during the installation and permit process, and didn't forget about me after the job was done. For example, after I was running for a couple months I had a question about a smell, that I thought came from the air handler. They took my concerns seriously and had someone out in a day. On site, the tech support person went through my concerns and resolved everything. I'd highly recommend Therma Tech! read more

Therma tech was awesome, 10/10! It was my first time reaching out to AC vendors due to a cooling issue found during inspection. The receptionist who helped with the reservation was very prompt and professional. And the technician was awesome. Although I had a pancake unit that they don't work on typically, he patiently explained and even kindly helped me replace the old filter. All in all I'm super happy with the experience. Highly recommended and thank you so much again for the work! read more

Very impressed with the knowledgeable and professional technician assigned for my inspection, Samantha. She really went above and beyond at inspecting our duct work and she obviously knew what she was doing. Henry, the owner, is really finding great people for his company! Thanks again, ThermaTech! read more

Great service. Always on time and great follow through. They installed the whole HVAC system in our house in 2017, 1st floor with furnace and the 2nd floor with heat pump. It was a whole new system which works great and since then they have been a great partner. Just today I contacted them for checkup as winter is coming and they did the whole tune up and changed some critical components. I like their membership scheme too. Good value. Highly recommended! read more

They are very responsive and knowledgeable. We had a problem with stalled AC unit on a "sunny Sunday afternoon", called them at 8am Moday and got a technician at our property at 9:45 same morning. Problem was identified and fixed within 20 min. Thumbs up! read more

Samantha was outstanding. She was literally outside standing because she arrived at our place earlier than scheduled. She had to wait a bit since it was the day before Thanksgiving. We had scheduled for 11, but she showed up before 10:30. I have no issue with punctuality--I'm the same way. But I was out doing groceries. Now, let's talk about the service. Samantha looks young, but she's super professional--a solid role model for the younger generation. She got straight to work and explained the issue clearly. I have an ancient gas heater, one of those that needs to be lit with a match or a lighter. Basically, she just needed to light the thing, but it took a while. While she was doing her thing. In my head, I'm thinking, this heater's gotta be replaced. It's over 40 years old. It's so old that Samantha doesn't even know the brand. As of writing this, the flame went out this morning, so maybe it's finally time to replace it. But Samantha did tell me what to do when the flame goes out, so I'll try to re-light it. Fingers crossed I don't burn the house down. TL;DR: 5 stars for Samantha. read more

We had an excellent experience from start to finish on our project! The initial estimate for a complete home installation of Heat Pump, Mini-Split, and new ducting, was priced competitively. The owner personally came to my home with his team to discuss the plan and ensure the correct components would be installed correctly. The installers were on time for work everyday and were professional and polite. They respected my home without causing damage or an unnecessary mess. The work was performed quickly and the results were flawless. No complaints. Great job. Thank you. read more

My service tech was efficient and honest. He checked the fuse and found that part was the problem. Other company tech didn't even examine the fuse; he simply said the whole AC system would have to be replaced. Quoted $18K. read more

Had a furnace which needed replacement. Therma Tech was one of the companies who provided me a quote. Loved working with their team from the very onset. I had a heat pump installed(A/C + heater). The team patiently answered all my questions(over email and phone), were quick to make updates to the quote when I changed requirements slightly and were overall very knowledgable, professional and polite. The install was super smooth and looks terrific as well :). They took care of the asbestos abatement, and took care of my old furnace and all the associated ducting. Would definitely recommend speaking to Therma Tech, if you have any HVAC requirements! A big thank you to the entire team - Adrian, Pablo, Chris, Lar and Vickie, for a job very well done. read more

Amazing service and follow up by Lar. He went above and beyond for us. Better pricing than some of other competitors we called. Therma Tech is our only go to from now on. read more

The installers just left my home. Julio and John did an outstanding job and did everything. Henry had said they arrived 15 minutes ahead of schedule and we're done early afternoon. They were courteous, explain things well and left my house clean as when they came I would recommend this company wholeheartedly. read more

Therma Tech installed our new central AC system today and I couldn't be happier. We've been using them for several years and it finally got to the point where replacement was the only option. Henry and his team were above and beyond expectations. Fair, friendly, very knowledgeable experts, answered all of our questions, clean installation, and didn't over sell us. We love working with local businesses, and Therma Tech didn't disappoint one bit. read more

Therma Tech - Heating & Air Conditioning/HVAC Near Me - San Jose, California

See all

I'm really disappointed in the treatment I've received from Therm Tech in recent weeks. While they initially did an excellent job on installation last year, I requested a quote for further work/adjustments to optimize our cooling situation. We scheduled a tech to come out, but they never showed up. Which was fine, they called right away explaining the situation and that the tech was on their way, just late. They never showed up and they apologized, and one of their guys had a phone consult with me instead, and emailed me some quotes. I followed up with follow-up questions as they had not yet seen the scope of the project I was referring to, and they never responded. I followed up a week later last month and never heard back. It's frustrating to say the least when they seemed so reliable upon installation. read more

The service and professionalism of all the techs who worked on our AC replacement was outstanding. I called at 4pm on Friday, and even though it was late in the day Yvonne called me back and said that Henry would be here at 8am on Saturday. Henry showed up right on time and soon found the problem. We needed to replace our existing AC. On Thursday Adrian and Pablo were here at 8am and had all the work done by 3pm.We are very pleased with the service we received from Therma Tech. read more

I now fully understand why ThermaTech has such a fantastic Yelp. Lar Heng, just finished an hour long "$88 Furnace Tune-Up" that included a cleaning, change of filters, plus a complete and thorough examination of every single critical component of our furnace and overall heating system. I can't overstate Lar's impressive work ethic, professionalism, honesty, and obvious commitment to customer satisfaction. Simply stated, my family has for decades been a loyal customer of a highly rated competitor of Therma Tech, but Lar Heng has personally demonstated that Therma Tech is not only superior to our former furnace company, but also that Therma Tech is truly deserving of its hundreds of nearly perfect Yelp ratings read more

Therma Tech was absolutely incredible. SUPER fast response, totally on time and they know how to fix even the hardest problem. Within the past 10 years, they've been our go-to for all heating and AC for my family and we trust and value their work. They have the best and most polite people on answering the phone and willing to go above and beyond to help. Henry, is always, so professional and knowledgeable. He cares about his customers. They are quick to figure out the problem and have all the tools to fix it right there on the spot. Their prices are absolutely reasonable, NEVER price gouge at all (which they can do given our circumstances). They are an honest business who we will continue to support! Thank you!! read more

When my less than one year old AC began blowing heat rather than cool air, I called Therma Tech from who I purchased the system. Their response was immediate and an example of A+ customer service. I cannot speak highly enough of the technician who arrived to diagnose the issue! Edwardo was not only knowledgeable and skilled in addressing the functioning of my heat and air conditioning units, but he was very respectful, kind, and fully invested in keeping me informed on what and why he was doing whatever he was checking. Edwardo was intent on making sure I understood not only what he was doing and why, but also comprehended how the AC should be functioning. The quality and genuineness of care was reassuring and refreshing ! I highly recommend this company and certainly value the service Edwardo provided to me. S. Sutton read more

'Twas the week before Christmas, my house was so cold. My furnace had died; it was thirty years old. I called Therma Tech with top ratings on Yelp. Owner Henry came and said he could help.
