HVAC Service San Jose

  Henry did an amazing job. Our AC wasn't blowing cool air but he was able to fix it in a timely matter. Originally, our appointment was scheduled in the afternoon, which is usually the time our house gets into warm uncomfortable temperatures. However, Henry was able to come in the morning. I was so relieved because I thought my baby would have another day of restless naps. I highly recommend this company because they're efficient, followed the masking protocols, and trustworthy.

  Excellent customer service and professional service repair. Alin knew exactly what was wrong with our ac unit. Worked fast, safely and had honesty and integrity. I will definitely be contacting  agin for future heating and cooling needs.

  This HVAC company is amazing. Started off with Vicky who answered the phone, so helpful and sweet. Called on Friday they sent someone Monday. Henry was fast and even saved me money   highly recommend everyone to use this company. Thank you Therma Tech

  Yet again, another piece of exceptional service!

My AC stopped emitting cold air all of a sudden. Called them and Vicky was able to provide an appointment for the same day! I couldn't make it due to my conflict, so got the first appointment for the next day!

Henry showed up, fixed the AC, in and out in under 10 minutes! Since the AC was under warranty (installed by Therma Tech), there was no cost to me!

Yet again, extremely reliable company to work with!

  The good, the bad and the great in using YELP and Therma Tech:  I don't have furnace problems very often, therefore when I do, I go to YELP to search for possible contractors.  I like to select possible contractors who have a 4 to 5 star rating and also contractors who will provide a "free estimate" for my job.  However, what I learned is that just because a YELP contractor has a high star rating and is willing to provide a free estimate does NOT guarantee a fair price for my job.  My first YELP 5 star contractor arrived at my home on time, and gave me 3 free estimates between $1,300 and and $4,500 to repair my furnace. [Tip 1: after getting the estimates, always ask about how long will it take to do the job?]  In this case. the contractor said it would take between 30 minutes to 1 hour.  [Tip 2:  does it seem reasonable to pay $1,400 for 30 minutes of work and replacing only 2 inexpensive parts, a capacitor and motor?]  Time to call Therma Tech who does not give a free estimate but was willing to give me 2 quotes over the phone and apply the cost of estimate if they came to my home to do the work.  I gave Henry a description of the problem over the phone and he gave me his opinion and estimate for replacing each of the two parts that could be causing the problem.  [Tip 3:  Be prepared to explain what is the situation with you furnace.  Don't just say it is broken!]  Henry identified the two parts and gave me an estimate on the phone for each part.  His estimates were LESS than 75% of the quotes received from the first contractor!  I gave the go ahead and Henry showed up in 20 minutes, inspected my furnace, and gave me a revised quote that was $200 LESS than what he had quoted on the phone!  I gratefully accepted; furnace was operational in less than 15 minutes and Henry was ready to go home.  I had a big smile on my face when I gave a check to Henry for less than $200 and I once again had a warm home.  [Tip 3:  be willing to spend some time and effort to get more than only 1 quote especially if the first quote seems unreasonable to you.]  Needless to say, I highly recommend Henry and Therma Tech; in fact my son will be calling him next week to check their furnace.  What a happy ending to Thanksgiving, hope you enjoy my story, Joe.

  Henry was so quick and efficient! I called at 7:30am and he was here within an hour. He found the problem and fixed right away. Extremely happy with the service we received. Thank you!

  had AC installed, two ducts added and the old furnace replaced in a house built in 1907.  this outfit is unusually good!  they stand behind their work.  nailed the city inspection/permit first go round.  Thank you, Henry, Vicky, and crew.

  I don't like to give a negative review especially since I watched them work at my neighbor's house where they did Excellent work installing AC to an existing furnace and assisting an Energy Company do an Energy Audit.

That said I was willing to wait a few days for Henry to show up to ascertain why my AC wasn't working.

Henry was able to get the AC to work at the furnace. He diagnosed a broken conductor in the cable between the wall thermostat and the attic furnace and suggested I contact an Electrician to rewire the thermostat.

After Henry left I noticed an extra conductor in the thermostat cable which could have been used???

Taking two trips into the attic and a twisted nerve I was able to replace the cable.
In checking the old cable I found that all of the conductors in the cable were fine???

Needless to say I felt I needed to contact another HVAC company.  I was able to get a referral from an neighbor and they responded the next day.

The HVAC Technician used the new cable and rewired my thermostat and rewired the furnace by removing all of the conductors on the terminals and starting over.

The HVAC Technician was able to get the AC working again.  Heat and AC working fine now.

Unfortunately, no real cause found for the AC not working.

  Can yelp please create a 10 star button!! Omg, let me just start by saying that just calling in and scheduling someone to come out was an ease. Vicky was on point with full all around best customer service ever, she tried to work with me on scheduling even though they were so booked up (I can see why!!). She was able to get someone out the very next day. Henry, came out right on time, and I kid you not, being the expert that Henry is, he was able to troubleshoot our issue in less than 5 minutes!!  I came back out after turning on the AC unit, which wasn't blowing out cold air, and my husband was saying bye to Henry! You can't beat this kind of service! Booked mark for all my future AC/heater needs!! Thank you Vicky and Henry as I'm sitting here in my office room with cold air 🙂 !!!!!

  Henry was on time, very efficient, pleasant & honest. Highly recommend...used them before great company!

  Needed a service on our AC... Henry came out and apparently all was good.  He changed one filter and left.  Said no charge.  He was maybe there 15 min.  Honestly. He could have charged whatever amount and we would have paid it.  Talk about honest.  
Def Call THERMA Tech. a mom n pop honest operation!!!!

  To start my AC was not broken but needed a tune-up/ service after 10 years. I chose Therma Tech even though they were not local to me. Vicki is one of the most energetic voices i have heard for the sales and scheduling staff. Very quick and to the point. Just as i thought it cant get  better, my service all was answered by Henry.

My service was done in a jiffy and since nothing was wrong, Henry ran my AC  temperatures, charged the unit and did a complete health check.
Again prompt, professional, knowledgeable and at the end he did not charge me as there was no repair involved.

ThermaTech is a permanent entry in my to-go list now. i could not be flattered more by the sheer professionalism and honestly.

Thanks Henry for coming over and Vicki for getting him to me!

  Wow!  Had a fantastic experience with Therma Tech.  From the moment we called them, they were responsive, helpful, and speedy!  Our a/c stopped working last night... Henry was here this morning, checked it out, diagnosed the issue and got it all fixed in one go.  Very impressed and would highly recommend them.  (In addition, the call out price was one of the most reasonable we found, and the cost of that gets deducted from the work that gets done!)

  This review is a bit overdue but better late than never! Long story short, recently bought a place with no real heating or AC (single radiator furnace and single wall unit in the dining area) and no attic. The best solution seemed to be a mini split system.

Coordination for the initial visit was super easy and fast. Henry came out that same week and provided a great price. FYI I received several quotes from other HVAC companies and ThermaTech beat them hands down. Not even close.

Signed the contract and the team was out the following week to install a 4 unit mini split system. They were very professional, showed up on time ready to work, and knocked it out in 3 days. They also took care of permits and kept me well informed of scheduling with the city.

Been using the system now for 3+ months with ZERO issues. It's been a life saver during the colder early months and hotter days now that we're getting into summer.

Henry and team are definitely 5 stars in my book. If you guys need HVAC related work I'd highly recommend ThermaTech!

  5 stars to Vicky and Henry!  Our AC went out last night and they decided to be open today due to the heat on a Saturday.  We had no cool air blowing, just room temp. Our capacitor needed to be replaced.  We now have lovely cool air again!  Very responsive!  Seriously from call to fix was maybe 30 min max.  Many, many thanks!

  Henry came out for servicing our AC. He checked and told us that only the filter needed changing. He changed the filter but didnt charge us anything for it even though we wanted to pay for the service. Really impressed !!

  Therma Tech was amazing from A - Z! It's rare you find a company nowadays that genuinely cares and does not try to upsell you. AC unit was not blowing cold and Henry came through to fix it in record timing. He's very respectful and wore a mask throughout the entire ordeal. I'll be a for sure returning customer. Highly recommend you choose them, you won't regret it one bit.

  Very professional staff, including the dispatcher, Vicky, and technician, Henry. The dispatcher was extremely friendly, and confirmed the appointment by both email and text a few days before the appointment . On they the morning of the appointment, the dispatcher had asked if they could arrive even earlier than expected, which was a good thing for my schedule. The technician, was extremely knowledgeable & honest. He fixed the problem in a matter of minutes, as well as explained why the furnace was malfunctioning. I would definitely use this company when it is time to actually replace my furnace. It is without reservation, that I would recommend this service company to others who need it

  This team is top notch. Experienced foreman, energetic team and great customer attitude. I am very delighted that they have a schedule for me!

3 and half days non stop installation of a mini split system with more than
9 people there from two teams at one point.

90%  done, now we just have to wait for a Cupertino city inspector!

  My furnace stop working and I called Therma based on the review. I am an engineer too. I am willing to pay for the expertise I do not obtain but really dislike any drama happening. I would say they are really professional. The technician comes in the do some testing step by step and my furnace is working in 10 minutes. That is what truly engineering is !
I definitely recommend Therma and will call them if anything happen in the future
