HVAC Service San Jose

  I received an estimate for an HVAC system replacement from Therma Tech. The estimate was $11,000 for a 2 ton system replacement which was $2500 more than the highest of 3 other estimates I received from other 5 star on Yelp HVAC companies. The estimate was hand written and didn't include the details of the other estimates I received such as the make and model of the replacement system or the break down of costs. Maybe they do good work but the price is too high.

  1 day before moving out, I saw water dripping from my AC Coil Tray. Called several companies and only Therma Tech was available to come same day.
I was quoted $120 to come out for diagnosis (which would be waived if I hire them to fix the issue).
The owner came out himself! Spent 10 minutes following the drain lines only to see the end of the line was not accessible.
However there was an air vent. He blew into it and immediately cleared the clog. We could hear the water draining out. Leak stopped! AC still works, and he didn't charge me ANYTHING. My Hero!!

  Can't say enough positive things about Henry and his team. Super responsive and presented me with all the options and pricing for a furnace/cooling unit and A/C upgrade. He and the team showed up promptly, observed social distancing and safety equipment protocol. The work was done thoroughly and I was contacted during the day with progress updates or is there were questions and issues. If you need heating or cooling repair or replacement, don't hesitate to call Therma Tech. Fair, friendly, hard working. Professional. What more do you need?

  OMG
Henry is the most knowledgeable and brilliant technician I have ever used. I can't recommend highly enough. Diagnosed and gave me all the options I needed, then completed the work in 15 minutes. And if that's not enough, an extremely generous bill. Thank you so much. You are my HVAC guy for life!

  I originally had Therma Tech install air conditioning at my condo back in April 2019. The coiler sits on top of our heater and since the heater was so old it also needed to be replaced. Henry was very responsive in helping to work with my HOA on the approvals. His price was also very competitive against other vendors I had contacted. His team was very fast and efficient in installing and verifying that it was functioning correctly. A few days after the installation our hot water stopped working. Their team was working next to the water heater during the installation and so I contacted Therma Tech and they immediately sent someone out to check on it. It turned out the pilot just went out. They treated it as a courtesy visit and didn't charge for it. Now that it's winter (Dec 2019) I tried to turn on the heater for the first time since installation and it wasn't turning on or staying on. Again I called Therma Tech and they sent someone out same day to take a look. Turns out our filter was already full of pet hair and wasn't letting the vent pull the air in. The filter was replaced and is now working perfectly. Again Therma Tech treated it as a courtesy visit and didn't charge for it. I am amazed by how wonderful their customer service is. Would highly recommend for anyone looking for Air/Heating at great prices with excellent service!

  Two days ago, a solar company installer made a mistake while doing the electrical wiring, and overloaded several circuits in my house.  We later discovered the furnace was no longer working.  Very bad timing as the weather had become colder and here we are, senior citizens, sheltered in place during this Covid crisis, trying to avoid getting sick and now our house feels like an igloo.  I started calling around and John, at Global Heating & Cooling, wasn't available but referred me to his friend Henry, at Therma Tech, who I called next.  He answered immediately and said he was available.  He set up an appointment for a few hours later, showed up on time (wearing a mask and gloves, which was considerate under the circumstances and I appreciated that), and quickly diagnosed the problem -- needed to replace the transformer.  I had mentioned that I would be asking the solar company to reimburse me for having to fix this problem that they caused, so Henry said that they, the solar company, would be able to replace that transformer if I wanted to wait and have them to do it.  Yes -- think about THAT for a second -- possibly against his own interest, he gave me an option I would have been unaware of!  Not a lot of businesses would do that.  He quoted me his price, which I felt was very reasonable, and we wanted our heat back on immediately, so we opted to have him do the repair right away.  Took him less than a half hour and it was all fixed.  His office also has a very quick and efficient system of appointment notification and invoicing, so the whole experience was smooth and easy.  No wonder he gets so many five-star reviews.  It's all about providing great, reliable service.  Thanks again, Henry ... you saved the day!

  My 24 year old furnace started acting up late last week so I called these guys to come check it out. The first tech sent out determined it was a filter issue so I replaced it with a new one, but it was still having the same problems. Another new tech was sent out to me Friday and determined it was the gas valve switch and a loose fan. Said they could order the parts but as it was an old unit and the company was out of business, I decided to just order a new one.

They ordered a new one right away on the Friday afternoon; Monday (today) they came and replaced the whole thing and added new insulation and a new wooden base. The 2 guys doing the installation were very polite and extremely efficient in their work! Left no mess behind at all and kept my hardwood floors scratch-free (bonus!). My new furnace is amazing and I'm SO grateful to have proper heat again!

Most definitely recommend these folks, they really did an outstanding job! Thank you!!

  My AC stopped blowing cold air. The condenser and coil wasn't on and the breaker was tripped. Who you gonna call? Therma Tech! Called and came out the same day. Inspected and diagnosed the issue quickly. Thought I was going to be told I needed a new Condenser but Henry, the owner/tech just said the contacts failed (they were melted) He replaced these and cleaned the unit (my bad) and it was up and cooling again.

He thought it might need Freon but checked and said it was ok (again so honest).

I highly recommend if you are looking for what is a rarity today... an honest repair company!

  Henry and Therma Tech did a great job. And I would recommend them in a heart beat. Fast, Friendly and Honest.

  Very happy with my service from Henry of Therma Tech. Responsive and thorough. Will definitely use them again.

  Best customer service!!

Our A/C broke down the beginning of summer. I had a consultation from another A/C service company who had already charged me $175 for 5mins of consultation and lot of upselling and to buy a new A/C unit.

I called Therma Tech for second opinion. They were able to accommodate me for consultation at short notice.

Henry was on time and provided expert opinion without any upselling. In my case, it was indeed old broken A/C that would need replacement. But Henry didn't charge me for that quick visit.
He would get my repeat service because I didn't feel like it was rip off to pay hundreds of dollars for a quick assessment, also he was honest and didn't try to gouge me with too many service subscriptions.

  We used Therma Tech a year ago. Because we were impressed with their fast response, service, professionalism, quality, I decided to contact them again for another need. This time it was for our air conditioning unit. Henry quickly responded to my inquiry and triaged my A/C the next day. That was Tuesday. They ordered a new part and had it fixed on Monday!  (I was expecting the part to take a week or two.) They even came early to repair it and had it repaired 15 minutes before 1p (they were scheduled to arrive bet 1-3p).  I highly recommend using the Yelp app to contact them for best service. If you need your AC or heating unit checked, please contact ThermaTech!

  I am seriously impressed with Therma Tech. We used them years ago to replace our AC unit, and all was good. Then today, in the middle of COVID lockdown on a warm afternoon, we tried starting our AC for the first time in a while. Problem - only blowing warm air. Called Henry and team and literally within minutes he was on the phone then at our doorstep (masked) willing to take a look. Incredible service, and the air now blows cool again. Yes, we were lucky he was in the neighborhood, but how often does that happen? Big kudos to these guys.

  I highly recommend Therma Tech hands down...for best customer service, promptness, and most importantly knowledgeable staff that saved me and my family from resent heatwave that just hit us in San Jose.  Our AC suddenly just stopped working two days ago while temperatures were above 100 degrees in shade.  So I searched for a local company in San Jose with high customer ratings and found few of them ....as ThermaTech was on top of my list of companies to contact .  So the next day I called them hoping to get service as soon as possible (like same day) however the scheduling lady (forgot her name..sorry)who answered the phone told me that the next available technician can visit us within the next two days at earliest due to high volume of service requests.  As I explained that we have our elderly parents living with us and If all possible can put a priority/rush on our service request...it would be much appreciated and helpful... so she noted my situation but said can't promise anything and schedule a visit for next two days. So I passed along our appointment information and date of our service call to my wife.  So I tried other companies as hoping for sooner appointment and got no sooner availability anyway.  Well surprisingly we got a call on same day around 6:30pm from Therma Tech and sure enough we were told a technician will be arriving within 30 minutes and if is okay with us?  OMG we were so happy to hear that and said please ...please...yes....for sure we are home.  At 7:00pm we had a technician by name of Henry who showed up and basically solved and fixed our AC unit in less than 10 minutes and as I was paying our service bill Thanked Henry so much and also asked him if he can give me his bosses name or email that we can send our gratitudes regarding our pleasant experience with both company and specially you Henry....so he smiled and said it was his pleasure ...as he gave me his business card for contact information (well Henry is the company owner) !!! WOW now that I call a true company with greatest leadership.

  Wanted to replace my 28 year old central Air Conditioning.  Requested a quote on Yelp and received a response within a few minutes.  Scheduled someone to come provide a free estimate the next morning.  They called about 15 minutes before arriving to let me know they were on their way.  They were honest about not needing to replace my evaporator coil since it had been replaced 13 years earlier.  I ended up getting 6 estimates and Therma Tech was the cheapest without a new coil, and they offered the best warranty on labor.  They are very honest and I highly recommend them.

  Another great experience w/Therma Tech!!  Therma Tech is a serious professional organization.  Henry (the owner) was very responsive thru Yelp and was able to provide a diagnostic and quote the next business day.  On the day of work, Chris and another staff member showed up on time and was already fully briefed by Henry about all the project specifics including some last minute changes I wanted to make.  I was able to track the crew online before they showed up so I knew exactly how much time I had left to prep the house.  The crew  was done in half a day and were very friendly, knowledgable, professional and answered all my questions in detail.  Most amazing of all this crew left the cleanliness of my house exactly the way it was despite doing a good amount of work in the attic  (the dirtiest place in the house).  Seriously there wasnt a speck of dirt on any of the carpets when they were done and out of here.  Literally the cleanest contractors Ive ever worked with hands down!!

Also everything is done online or via ipad / email /Yelp messaging with them.  You can pay by credit card/Square when the jobs finished - truly efficient and easy.

Vickie in the office is also very friendly and helpful!  Top notch organization all around from owner to workers and staff.  Highly recommended!

  I definitely recommend Therma Tech! We called right after they opened and they were able to make it out to fix our AC unit that same morning! Henry was very professional, efficient, and knowledgeable! We will be using Therma Tech in the future if we have any other issues!

  Henry with Therma Tech showed up to troubleshoot why my blower motor wasn't working at 8:30am and was done by 8:50am.  He was knowledgeable and efficient.  Turns out the flux capacitor failed and needed to be replaced.  Lol

  We had to have our old Ac and furnace replaced and after searching on yelp I decided to contact Henry with Therma Tech. He came out the very same day to look things over and gave us a diagnosis. He was very knowledgeable and honest about what was going on...I was impressed and felt comfortable giving him the job.

We are extremely pleased with the work that Henry and his crew (Chris and Leo) did. They were super knowledgeable, friendly and true professionals.

Thank you so much...you guys are awesome!
I highly recommend Therma Tech.

  Our Air conditioner quit working.These folks are great! Vicki made getting an appointment easy.  Henry showed up 2 hours early and had the problem diagnosed in a matter of minutes. Very professional and reasonable.

  I researched and received quotes from a few HVAC companies before going with Therma Tech. I went with them because they gave me options to what I was looking for AND they were responsive to my calls/questions. I had a new furnace and AC unit installed and this team is great. Henry, Vicky, Chris and his team were all professional and worked with me throughout the entire process. Chris and his team finished on time and cleaned up afterward. This team made this process easy for me. Much appreciated.

  Loved how Vicky kept her promise to hook me up with Henry, the boss. They have a pretty good scheduling system via email and SMS. Henry is nice enough to give me a run down of what diagnosis he'll perform and how much each procedure costs and oh, he won't push you to install a new system. This guy is just as good as DG, but I ended up not to go with Therma Tech  due to the timing. I definitely encourage ppl to give them a call.

  We had ducting work done by them today. Impressive work and professional crew. This co knows their trade and were very easy to work with. The crawl space was tight and it was not easy but the technician Chris did not complain. He was polite, detailed and thorough inspite of a long day and subsequent commute. We were in a time crunch and they could have seized the opportunity but the quote was consistent with no tacky add-on fees.

I highly recommend Thera Tech and will be using them for all our future HVAC needs.

  Excellent service, awesome people to work with. I had an excellent technician visit my place. The problem was my furnace made huge sound like an aircraft taking off. And I dragged calling someone to fix it for quite a long time.  

Any HVAC person you call, there is a fee just to come to your place.  Good thing about Therma Tech is that they will deduct this cost from your bill if you get the work done from them.

In my case the technician said that the furnace is in very good shape. The sound is normal but its loud because of improper filter used.  We changed the filter ourselves based on his suggestion and it worked !!!  

He didn't even charge for the diagnosis/visit fees saying that he didn't do anything.  Will definitely call Therma tech for any future furnace or A/c issues.

  This is a follow up to my previously posted review. I appreciate the owner's following up with my review. Although the problem with my A/C was a new one and not related to the part your company replaced, you insisted on compensating me an amount that was double the repair bill. This shows your sincerity and focus on customer satisfaction. I appreciate that. Since I still feel that you do not owe me this compensation, I donated it to a needy 3 year old girl who needs inner ear replacement operation in China. You can count it as your donation in spirit too. God bless

  My encounter started with a call to Vicky at their office and she was wonderful and refreshing.  Let me explain, Its 96 degrees in San Jose, Ca.  My AC went out!  I was in NEED OF A FIX!  I knew places would be busy, so I planned on being told I would have to wait.  I was looking through YELP and I saw the reviews here and I was like okay lets try this place.   Vicky answered,  like I said, I was "expecting to be told it would be a day or two" but NO! She was so nice and patient with me and she surprised me by letting me know that there was a 1pm appointment that same day.  I was like WHOA!!! YES please.  She made the whole conversation and scheduling easy and I had even forgot that I was in a sweat box.  She even let me know that my tech was Henry and he was the owner, so not to worry.  She was just so personable, I really didn't even want to hang up the phone with her.  

I received an email notification about the appointment, then a text notification letting me know when Henry was coming, YUP I could see the estimated time Henry would be here. That is way better than "UBER".  Sure enough the doorbell rings, the dogs bark, I grab my mask and open the door and there is Henry with his mask. I was delighted. I see he was social distancing, or I would have hugged him. He asked me to let him in the back yard to see the AC unit.

Let me tell you something, Henry was very honest and I liked that.  He told me my unit is still under warranty and I CAN call them and they COULD come out to fix it for free, or he could fix it for a fee.  I was in a dilema.  But its HOT and Im too sweet to be in heat. SO I said FIX IT.  He did and he changed out my filter too.  I appreciated his sense of humor, help, professionalism and honesty.  Even though I paid it was money well spent and it was a great team that did the work.   Thank you.

  We just purchased a new home in San Jose, which had central heating but no central air. We called Therma Tech for a quote among about 4 other companies. Henry came out to the house, gave us a quick and competitive quote, and told us he could have our new AC installed in a couple of weeks.

As promised, Henry showed up on time with his coworker Chris. Together, they were incredibly professional, got everything installed on time, and even had to deal with an unexpected part failure on site. Because the part wasn't something that we were expecting to have to replace, Henry was incredibly fair in working out the cost for that issue. I know there are a lot of HVAC contractors to choose from in the area, but we are so grateful to have found Therma Tech - they are professional, fair, and honest. I highly recommend Henry and his team!

  Great team, careful, polite and clean. We just got a new AC and Heater installed. Arrived at 8:30am, done by 2:30pm. We got a few quotes, this company and owner seemed the most honest and knowledgeable. We'll hire them going forward.

  Our AC and thermostat were in need of some updates and Henry from Therma Tech arranged to come out and fix them within short notice. The service was quick, professional, and clean. Definitely recommend Therma Tech for all HVAC needs.

  These guys are great. Heater was acting up. Took a while to get them out, but it is busy season so very understandable. Quick to call back and great communication prior to the visit. Fast diagnosis and very fair/ helpful. I would not hesitate to refer them or call again.
