Henry is the reason why Therma Tech supersedes all the other HVAC businesses. We have an ancient furnace-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. read more

Had a new furnace installed by a different company and they aren't able to adjust airflow. We weren't feeling much airflow after installation. Called the MFG and saw their list of experts. Decided to call a few for a quote and connected with ThermaTech. They were very responsive and easy to set up, confirmed that they know to work around the specific model. Miguel text when he was on his way, showed up right on time and was equipped and wore shoe covers. Professional - talked me thru what he was going to do and was ant to make changes and asked me to confirm the airflow was good. Was very patient and let me check all the air vents multiple times - a very thorough job. Paid right when he left and at a very reasonable price. Will definitely call ThermaTech again and highly recommend! read more

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

I was incredibly happy with the service from Therma Tech. Jose did a fantastic job on the work and did it in a way that was far better than what I expected. I had several HVAC companies / contractors come out to bid, and few even understood what to do. I would not hesitate to work with Therma Tech again. Very trustworthy and they did an outstanding job. read more

Miguel was friendly and efficient. No complaints. He made sure my air conditioner was working well for the summer.

Wow. I've gone through so many HVAC companies, and finally, I found Therma Tech who are the ultimate pros. They came in with a highly competitive quote and incredibly professional---from scheduling to get asbestos removed, heat pump installation, to ensuring everything is up to code and scheduling the inspection. Amazing. read more

Great overall experience and competitive price. The process from overall quote, to installation, clean-up and communication was excellent.

Simple. Excellent in all ways. Honest fair quote and fast installation. The best. Highly recommended

Super fast response times and were able to come out the same day within an hour! Fixed our AC issue and repaired very promptly and with care. Also offered us a quote for recommended future services which was appreciated. read more

My experience with Therma Tech was exceptional. They were able to get me in as an emergency appointment, which was greatly appreciated. Their customer service was fantastic; very helpful and kind. The service technician, Miguel, texted 15 minutes before his arrival and was exactly on time and within the timeframe window I was given when the appointment was made. He quickly assessed what the problem was with my air-conditioning unit and was able to fix it within 20 minutes. He was friendly, knowledgeable, and prepared to fix the problem. The repair cost was affordable, and he gave me a few options - I appreciated that. I will only be using Therma Tech going forward for my heating and cooling needs. Thank you! 10/10! read more

I had a great experience with Therma Tech. They recently replaced my condenser and coil, and the entire process was smooth from start to finish. Both technicians were extremely respectful, professional, and clearly knew what they were doing. What really stood out to me was how they went above and beyond--they took care of a few small additional tasks without me even asking, and didn't charge extra for it. They also took the time to cover the flooring to keep everything protected and made sure everything was thoroughly cleaned up before they left, which I really appreciated. Overall, I'm very impressed with their workmanship and customer care. I would highly recommend them to anyone in need of HVAC services. read more

Miguel came very promptly for both the diagnostic and returned early the next day to fix it. Very professional, nice, easy to do to business with. Would definitely recommend your service to others read more

Their maintenance service is great! The technician explained his findings after the maintenance. And today we had a minor issue and they made extra effort to come same day. No scare tactics or anything like that. They are our default go-to. Response and service is top notch - Highly recommend! read more

Therma Tech should be every Bay Area homeowner's starting point in the search for an HVAC contractor. The AC at my parents' 2-story house went out in May and I surveyed every reputable HVAC contractor in the area. I wanted a system that would do a better job of handling the temperature difference between the top and bottom floors of the house than the old system did. To my surprise, each contactor I talked to offered vastly different approaches and a good number pushed for solutions that were clearly compromised at a very uncompromised price point. We ultimately went with Therma Tech and their suggestion to put separate Carrier 2-ton air handlers for each floor (one in the attic and one in the garage) with a heat pump compressor outside. Generally, this is the best performing but most labor and equipment intensive way to go about it, yet Therma-Tech's quote still came in lower than a lot of the other contractors who just wanted to replace the existing unit with another unit, usually of a cheaper brand, and perhaps add a zoning system. When it came to doing the work, the crew was exceptionally professional, clean, and patient with me even when I got excessively nit-picky, which I admittedly did constantly. The workers were smart and knowledgeable, explained everything I needed to know and offered options when there were different ways to go about things. They asked countless times if we were happy with everything and followed up after the job was done. I simply could not ask for better quality service. Six months later, the system is working like a dream. Whisper quiet, even temperatures between floors, and the house is more comfortable than ever. Most importantly, the parents are happy. I cannot recommend Therma Tech enough. read more

Great experience with owner who di work himself when on a cold day the furnace stopped working.

We had our annual service and the technician Samantha was incredible. She did a detailed tune-up of the whole system, checked every single thing, replaced filters, and was super polite and helpful. Great service. Highly recommended. read more

Therma Tech was great from start to finish. The quality of work and the people were professional and very knowledgeable. They had solutions other companies missed. I would recommend Therma Tech to everyone that wants an HVAC system. We got a great value and saved even more because they were able to correct any problem we had themselves. read more

Had new furnace and ductwork done and they came in and went right to work. Their work was top quality and I would highly recommend Therma Tech if you want quality work at a fair price. read more

Henry was on time , explained the problem and the options clearly. The problem was fixed very quickly. I will definitely be using them in the future read more

Therma Tech was super knowledgeable, respectful and quick to diagnose the issues with our heater. The rep gave us estimates for multiple options without pressuring us to choose one over the other. He was also very informed about the available energy incentives and upfront about the pros/cons of various technologies. We had previously had other companies out for estimates and Therma Tech was very aligned with the other companies. The installation was painless. The guys showed up on time, were respectful of our home, and kept us informed of their status. They ended up needing to come back a separate day to complete the installation due to some weird wiring but again, very communicative and professional. Will definitely call them again for maintenance/repairs. The system works perfectly now! read more

Jared gave us outstanding service! He was punctual, which is very important to us, and very knowledgeable. Any questions I had would be resolved with an answer and explanation he provided. He walked us through every course of action he took. He kept checking in with us to see if we had any other questions or concerns that he could attend to. Over all GREAT customer service. I'm glad he is our technician that will be keeping up with our AC maintenance unit. read more

My A/C suddently stopped working - it was still blowing air, but it was no longer cold. Jerod from Therma Tech stopped by and diagnosed the issue within minutes. He was extremely knowledgealbe, and took the time to let me know some things I can do to keep my A/C unit running longer. He also told me some thing to watch our for with my A/C unit. I was extremely impressed with how helpful and knowledgeable Jerod was! Fortunatly it did not take much to fix my A/C unit and get it working again. Jerod was honest and happy to spend as much time as necessary to get everything right. If you're looking for someone to take care of you A/C unit, be sure to setup an appointment wtih Therma Tech, and hopefully you will get Jerod! 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

Yesterday a Therma Tech crew, led my Jose Robles, completed replacement of both my 28-year old furnace and AC units with new ones. It took a team of two people to replace the furnace in one day and a team of three to replace the AC unit, also in one day. They were competent and efficient, and did high-quality work. There were also pleasant to work with and were willing to answer questions and explain things. On the front end, prior to placing my order with them, when I was exploring various options, their office staff were prompt and responsive in their communications. On the pricing side, they were within 10% of other quotes (they were higher), but appeared more professional and inspired in me greater confidence in the quality of their work. However, I would recommend to prospective customers that, before they commit to any particular technical solution, to explore all other solutions, along with their pros and cons, including repair vs replacement. For example, if you are considering a heat pump to replace your AC + furnace, understand it not only from the standpoint of initial capital costs, but in view of operating costs in the long term, i.e. gas-operated furnace vs electrically-powered heat pump operating costs, as gas is cheaper than electricity for the same amount of energy. I do not feel that these were explained to me at the front end of my discussions with them -- but should have been. Nevertheless, I do recommend them, as they do know what they are doing. 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

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

Tech Jared is great! Courteous, professional and kept me informed the entire time. Thank you!

They were wonderful replacing our ducts. Great communication and pricing. Highly recommend them.

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

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

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

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

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 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
