Henry is incredibly knowledgeable and was great help troubleshooting HVAC system. Would highly recommend.

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

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

Henry was amazingly efficient! He has updated some AC units in my condo, which made it super easy for him to go to the unit and fix all in the same day. I went from a hot 85 temp home to a nice 75 temp within an hr. Very happy with the service and support from Therma Tech! read more

We just had our gas furnace and A/C replaced with a heat pump. Henry was spot-on in recommending the latest Carrier model, even ensuring it was one that works efficiently in colder zones.

Straightforward service with no games. read more

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

Air conditioning service call. Wonderful service. Diagnosed quickly and performed service without any high pressure sales talk. Courteous.

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

Signed up for annual maintenance. Tech checked 2 AC condensers but didn't check the AC filters.

Therma Tech was able to fit me in, same day on the hottest day of the year (so far). The tech arrived 1.5 hours early and had diagnosed and fixed my AC within 30 minutes. I am very happy with the service I received, read more

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

Our AC quit working when it was 98 degrees yesterday. Unit is 6 years old. I called Therma Tech at 8 am today and scheduled Henry to come out 2-3pm. He had it running in no time. The capacitor failed due to high heat. He replaced it and added another part to keep that from happening again. We are so grateful. read more

Quick, easy and inexpensive. The tech arrived on time, actually a few minutes early, found the problem and fixed it.

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

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

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

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

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

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

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

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

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

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

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

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