HVAC Service San Jose

  My AC went out this week and it was hard finding someone to fix it.  I called at 10am and Henry came out at 1:45pm... fixed by 2pm!  He immediately knew what was wrong.. I honestly felt dumb.  Lol.  Awesome service and definitely would use again.  Thanks to the Therma Tech team for getting it running again.

  Like many reviewers here I was skeptical of a business getting top notch ratings and reviews across the board. Turns out my skepticism was totally unfounded. During the recent heat wave, every AC repair shop including the ones who had a maintenance contract on my unit since the previous owner, was not available to come by any time soon. Fortunately, I came across Therma Tech's ad on Yelp (1st time I have ever clicked on a sponsored listing). Next thing I know I am scheduled for a diagnostics test with Henry who generously offered to stop by on his way home. He was on time (I was late on the other hand), literally took 3 minutes to accurately diagnose the issue and told me upfront what it would cost me if I did the repair myself vs if I asked him to do it. No BS, no upsell. I was very impressed with his knowledge & honesty and I decided to ditch my current company (who couldn't even be bothered to give me the time of the day) and sign up with him for annual maintenance of my heating and cooling. Outstanding service, period.

  Give Henry ten stars.  He not only came out on a Saturday, he did so within an hour of my call.  I'd just been given a $9000 estimate from another AC repair company, and was in a state of shock.  I told Henry all the other guys had said, including their assessment that I would have to replace the capacitor and most of a five-year-old system.  Within a few minutes he'd ascertained that the breaker had switched off, and then started up the fan.  He also replaced a small part.  Then he refused to take any money.  "For what?" he asked.  He acknowledged the system had some years on it and would need to be replaced, but not yet.  He again refused to take any money.  I deeply appreciate Henry's honesty and quick attendance to my problem.  I don't think I've encountered a more intelligent and honest businessman.

  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!!

  Professional and courteous service. They came out to my place twice, and were always on time as scheduled.

  Great services from Henry and his team.  They came and gave me free estimate and were  honest about what went wrong with my heating system without any expectations  of trying to sell their services.  When I made the decision to use Henry's company, they came right away and replaced a new furnace because the house was super freezing without heat.  Highly recommend Therma Tech and ask for Henry. Thank you all again for  being so prompt about everything!

  Professional, courteous. Showed up on time and got the job done. Replaced a blower motor and capacitor in my Carrier system.

  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.

  I called and made an appointment the same day. Henry stop by checking unit. He provided profession suggestion, and answered all questions regarding maintenance and replacement. Awesome service!

  Therma Tech got us in their schedule ASAP.  Upon arrival they quickly assessed and solved our A/C leakage issue with a very efficient solution, and suggested some very useful tips for DIY-ers like myself.  Will certainly use them again, thanks!

  Just had AC installed last week by Therma Tech. The job was done quickly and professionally. Henry and his crew are very responsive and very knowledgeable.

  Same ol' story - heater fails, my usual team is suddenly unreliable, hit Yelp for multiple quotes and to talk to the owners and techs. Prices don't usually vary too much but the conversation allows me to determine who is easy to work with. I made a great choice with Henry - the man is upfront, concise, and friendly. We agree to terms, set the date to start and sign the contract.

Then we hit out first hiccup - the techs scheduled for my day get the flu (not that one). Bad sign. This is usually where a lesser company would fail, make excuses, be defensive, and push our schedule so far out to summer I may as well buy winter coats (for CA, right?).

Luckily, I got Vicki - Henry's super office do-it-all - who owned the situation, quickly setup a new appointment, and kept me in the loop so often I began to feel she cared more about us getting heat than I did.

The job was completely with excellence, care, and speed. Impossible to ask for more. I already have this team up for another heating situation on another home. It's the start of a great new relationship.

Thank you Henry, Vicki, and your staff.

On to the next job.

  I called thermatech on a Friday and Henry have us an appointment for Saturday. He diagnosed the issue with our AC right away, fixed it in a couple of minutes and for a reasonable price. He also gave us advice for the future on our system and regarding city codes. Overall a quite pleasant experience. Will definitely go to him again if we have any other issues.

  The best. On time. The technician was great. Repaired our air conditioner in a short amount of time at a reasonable rate. Thanks. Would highly recommend and would call them again

  I am very pleased with my experience with Therma Tech.  

They came out promptly to give me an estimate on replacing both the furnace and AC unit.  The estimator was honest and straightforward with me, letting me down gently when he said I'd have to replace both units.  The price quoted was very competitive.

They managed to schedule the work for the following week, despite being during one of the hotter spells during the summer.  The technicians who did the work were prompt, polite, and very efficient.  Two techs took one day to install both units.

A couple of small hiccups during the city's first inspection, which they fixed almost immediately.  For the second inspection, Therma Tech co-ordinated schedules to send a tech out to talk on the spot with the city inspector and the work passed.

It doesn't get much better than this.

  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.

  I really appreciate the quick and professional response! My AC was blowing warm air, I checked the filter and it was dirty, but removing it didn't fix the problem, so I called Therma Tech (top rated local company on yelp!). They offered to come out the same day, but my schedule didn't allow so we set up the appointment for the following day (Friday) in the afternoon. They called to confirm on Friday morning and arrived 10 mins ahead of schedule.

As suspected, the Freon (R22) was low on the unit. It took 4 lbs! which was pretty expensive at $100/lb, but a few minutes later the system was blowing cold air again. I hope the system doesn't have a big leak, there's really no way to tell. The tech gave me a list of options before doing the repair and showed me the scale and pressure readings since I was interested... I appreciate that too!

Thanks again for a quick and painless service!

  Therma Tech (and Henry, in particular) is off the charts, hands- down one of the best appliance companies I've ever worked with in terms of knowledge, timeliness, friendlessness, and also incredibly humble about the extent of his knowledge.  "I'm just doing my job" he said when I complimented him on the amazing service.  Our AC broke due to the recent heat wave, so I turned to Yelp.  Therma Tech has the best reviews (and also the highest NUMBER of reviews) so initially (similar to a few other people who also mentioned this on the site) I was skeptical.  I gave them a call with the goal of trying to set up an appointment ASAP, which given the 100 degree weather I assumed would be 1-2 days due to the high demand.  "How about if I say I'll be there in half an hour?" was the response I got on the phone from Henry.  Sure enough, he arrived right on time, professional, respectful, honest, and ready to get down to business!  He diagnosed our problem right away, gave us a few different options to choose from, and then wrapped up the job in 10 minutes.  We were completely blown away.   If you have any AC issues at all Henry is the man.  Don't even think twice about giving Therma Tech a call.  We feel so incredibly grateful for finding Therma Tech!  Thanks, Henry!

  Our AC went out last week, and I know we needed to upgrade both that and the furnace unit. I called ThermaTech and was contacted almost immediately, and Henry came out a couple days later. He was even early to our appointment. Henry was extremely informative and professional. I am waiting to get one more bid just to do my due diligence, but I am pretty sure we are going to go with ThermaTech.

  Our central AC stopped "dead" during a heat wave.  We called and Henry, the owner, came out the same morning.  Henry immediately identified our problem and by that evening we were up and running again.  The cost was much less than we expected.  He was efficient, very knowledgeable, and very respectful.  Well if we ever need AC work again we're calling Henry!!!  Rex Naden, Blossom Manor

  We worked with Therma tech to install a new A/C unit. We found them to be extremely professional and courteous. They responded to our inquiry quickly, understood our needs, and had a new a/c installed within a week. After installation, when we noticed the unit making a lot of noise, they came back promptly and installed additional ducts which completely solved the noise issue. They refused to charge extra for the additional work and all the extra ducts.

  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!

  Henry Elia/THERMA TECH is AMAZING!
Here is my story:
- Our AC died. A different HVAC company diagnosed it as not fixable, and charged us "diagnosis fee".
- Called THERMA TECH for cost estimate of a new AC system installation.
- Henry came. He first looked at the old AC. He checked the wire connections, did whatever "magic", and the old AC started working!
- Instead of selling us an expensive new AC, he said, "Your problem is solved! Call me if any problem."
- NO charge!
- None of the other sales people looked at the old system. They just wrote new estimates!
- I found out that Henry is the owner of the company! I see how he built this business: Honestly. By treating client's money as he would treat own money!
- I know that I will go to only Therma Tech in future!
- If only all service companies were this good......!

  Technician came out very quickly even in the middle of high demand. Our system was knocked out by a power surge - no display on the thermostat. I had tried the reset procedure with no improvement. Technician took one look at this and said it was likely the low voltage transformer.  He then checked that and it was blown. He put a new one in and the A/C is back on.  Perfect!

  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.

  I've had Therma Tech out to my house a couple times in the last couple years to service my old AC unit. They tell it like it is and fix it like it should be at a good price. When I have to get my AC repaired or replaced, I call Therma Tech.

  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!

  We got extremely lucky! I called and Henry was literally at our house within 5 minutes. He came in diagnosed the problem, had the part in his van, replaced it and off he went. Great service friendly technician. Made some recommendations for upgrades but didn't do a hard sell. Will recommend. 5 stars all the way!

  My furnace went on and off sporadically with and without heat for a few days before just blowing cold air. I tried few quick fix tips from YouTube but didn't work so I called a furnace company that had 5 star review on Yelp. He came to run diagnostics and replaced pressure switch but didn't work. At the end, he thought it was the circuit board. He wasn't completely sure since he would have to get a working board to test it. He said it would cost $800-$900 to replace and install. His other suggestion was since it wasn't a good brand and was 2003 model, I should think about just replacing it. I knew many of the articles I've read confirmed this so I decided to consider this option. He gave me his estimate of about 5k. He said he would waive $95 diagnostic fee if I got the board or replaced the furnace. I told him I would get back to him after getting other bids. What I didn't agree with was that he charged me $95 even though it wasn't confirmed definitely that it was the board that was the issue. I understand he would have to buy or have a working board to be 100 percent sure but even I guessed it was most likely the board after awhile. So I don't agree he should charge me for a diagnostics he's not completely sure about. I really didn't like that he would even charge for diagnostic but another company said they charge $140 so I thought it was a common practice. Any way, I called another company with good Yelp review to get estimate on a new furnace. I figured if I can get it down close to 4K, I might consider getting a new furnace. I called and they booked an appt to have someone out to give me estimate. I did find it a little odd they didn't ask any questions on why I'm looking for one.
Then I called Therma Tech. Vikki answered. She was pleasant to talk to. I told her I needed estimate and asked if she could give me a ballpark figure if it was a basic installation. She said she would let me talk to an installer for more detailed info. Henry answered. He is the owner of the company. He asked me why I was looking for a new furnace. I told him my issue. He then told me that though it's an old model and confirmed it wasn't the best brand, he didn't believe it was old enough to warrant a new furnace without first checking out the issue with the furnace. He wanted to look at it to see if he can diagnose the issue. He asked if I can wait two days for him to come out. He said if not, he can send one of his technicians the next day. Truthfully, I was impressed with his willingness and confidence to come out to fix it without having to replace the whole thing. And he wasn't going to charge me for a diagnostics. So I said I'm willing to wait for him to come out even though temp has been 50-55 at night with 3 kids. So, here is the customer service and his work I felt really separated his company apart from other companies in general. I got text and email with appt schedule. Appointment day, I received text with their location tracking info saying they are on their way. He came on time and was very personable and professional. Even before entering my house, he was putting cover over his shoes to come inside. I told him it wasn't necessary.  But I did appreciate him doing this. As soon as he started testing the furnace, I felt like he could solve the problem without replacing it. He knew his stuff. He went through testing after testing without any hesitation. He confirmed it was the board. He showed me how he tested to confirm it was the board. He said he would order the part to replace the board. He felt confident I did not need to replace the furnace. He said even though brand wasn't the best and it was an older furnace, it was still in good working condition. He said he can replace it for $595. And he said if it wasn't the board, he would not charge me for anything. He said he would have his technician come out the next day to replace it. Again, I received an email confirming my appointment. The following day, I received a text notification notifying me that a technician with his name included is on his way with location tracker included in the text. Barsin came on time and replaced it. He, like Henry, put shoe cover before coming in but I told him it wasn't necessary. They are very consistent in their practice on how they do things and how they treat customers. He fixed it in less than 30 minutes. I was very impressed from the beginning to end. Therma Tech will be my first choice and go-to company for all HVAC issues in the future. I believe this is only my second or third review on Yelp but I am more than happy to do it. And at no time did Henry or his technician ask me to do this which made me want to do it even more. Thank you Therma Tech! You guys are professional, personable and affordable!

  I have a room in my house that always runs hot even with the AC on full blast. It can be Antarctica in the other bedrooms, but that one little room is a sauna. It also happens to be the room I rent out, so it's a big problem.

I called Thema tech, and they had someone come and check it out for free. He climbed up into the ceiling to take a look, and explained what was going on. The vent in that room was smaller, and it was ducted in a way that it wasn't getting much airflow. He gave me a reasonable quote for re-ducting the house, but also recommended that I consider other options such as a fan.

I really appreciated that they were willing to give me the best solution, even if it meant not getting my business. The fact that the diagnosis was free is a huge plus.

If I ever decide to move forward with re-ducting, I will definitely call Therma Tech.

(Tip: call them soon if you're thinking of having them come out to your house, since they do get booked up!)
