Reviews
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!
Thank you for such prompt service! Our AC is working again. Got response as soon as service request was sent out. Friendly and honest help.
Outstanding service! Came home from grocery shopping to find our condenser unit had failed, 5:30 PM on Friday! Hottest day of the week as well, Called Therma Tech. Had a technician on site within 30 minutes. Tech was on his way home and turned around to service our system. Repairs completed quickly and we were back on line in less than an hour! Could not ask for better response and service. Thank you Therma Tech.

Jared came out to do an A/C tune up. He is professional great customer service. I would request him every time.
Great service. Prompt response. Best HVAC company I ever called
Nice and quick got ac working again
Therma Tech came on time and Jared was respectful by putting on his boot cover when he came in our house. Asked what the problem was and where our HVAC, and compressor located. Did his checks and picture taking, diagnosed the problem and replaced what needs to be done plus he washed our compressor. Quickly solved our cooling issue in less than an hour. Summarized what he did and offer things that needs to be done in the future. Gave me my bill and discount, paid with credit card and he left afterwards. It was a pleasant experience and recommend this company to friends.
Therma Tech came out on a Saturday within 10 minutes after I called them to repair my a/c compressor unit. The repair was quick and efficient. Thanks for the great work!
Therma Tech was absolutely incredible. SUPER fast response, totally on time and they know how to fix even the hardest problem. Within the past 10 years, they've been our go-to for all heating and AC for my family and we trust and value their work. They have the best and most polite people on answering the phone and willing to go above and beyond to help.
Henry, is always, so professional and knowledgeable. He cares about his customers. They are quick to figure out the problem and have all the tools to fix it right there on the spot. Their prices are absolutely reasonable, NEVER price gouge at all (which they can do given our circumstances). They are an honest business who we will continue to support! Thank you!!

I appreciate the service Therma Tech provided especially today (7/11/2025) that was forecasted to have heat wave hitting 97F. Expected a whole day work, the job got done in early afternoon and I'm able to enjoy my AC now.
When my less than one year old AC began blowing heat rather than cool air, I called Therma Tech from who I purchased the system. Their response was immediate and an example of A+ customer service. I cannot speak highly enough of the technician who arrived to diagnose
the issue! Edwardo was not only knowledgeable and skilled in addressing the functioning of my heat and air conditioning units, but he was very respectful, kind, and fully invested in keeping me informed on what and why he was doing whatever he was checking. Edwardo was intent on making sure I understood not only what he was doing and why, but also comprehended how the AC should be functioning.
The quality and genuineness of care was reassuring and refreshing ! I highly recommend this company and certainly value the service Edwardo provided to me.

They gave a fair price and completed the job fast. No problems after that. My AC works perfect now. I will call them again when needed for sure.
Chris was a great guy. His work was awesome and solved my problem with excellence and proficiency. Very professional. I would recommend him to anyone
Jared was such a great technician. He explained everything from beginning to end and detected the problem and fixed it right away. I am so happy I used this company and Jared. He was such a nice and knowledgeable tech.
Cooling season service for 2 furnaces and condensers. All was completely promptly and efficiently. Nothing needed to be done.
If you are lucky enough to have Samantha as your technician, you know you are in good hands. Samantha was incredibly thorough and walked me through her full inspection and items that needed attention. Efficiently worked thru the entire HVAC system and ductwork. I appreciate her good work and care - a very good professional...A+ job.
