Friendly service when you call, appointment times available within a reasonable window, and expert technicians to perform the on-site work. My tech, Jesus, was efficient, clean, thorough, and took time to explain the work he was doing. I like that an annual maintenance program is available. Glad I held out until I found this excellent HVAC company.

Jesus was very professional, did a great job with our maintenance, checked our ductwork. Very good service! Thank you ThermAll Heating

We called because our heater was out, and they sent somebody out in a few hours to fix it. Ray was incredibly kind, respectful, amd helpful. He quickly fixed the problem and we would be happy to work with him for any HVAC needs!


She was very detailed in the cleaning and checking of my mini-split system.

What a delightful experience! We noticed our heat was out at 2am - and it was 22 degrees with 15 inches of snow on the ground. The house was down to 52 degrees and we were shivering. I called thermall and their after-hours person said she would ring back at 8am or soon after - which she did.
She dispatched a heating technician who found the problem - which had been fixed just a week earlier by a cross-town competitor - not well as you can see.
Then she put us on the emergency install list, had a team there the next day - and loaned us space heaters to keep us warm until they could come.
The team that came - amazing - fast, organized, skilled, tidy, polite and so able to solve our problems.
They installed a new Daikon heating and cooling system in one day - and it is wonderful. Much more constant, less blowing air, and we have reset our thermostat from 67 to 62 because it is so much more efficient.
They even cleaned up 100 percent of their mess. Wow - they have our business for life - and their system has a year of 2 hour guaranteed service - but this is a service plan we will buy for many years to come.
In the middle of a pandemic, supply chain that is difficult and generally hard to get return calls, these folks are AAMazing!

We had the pleasure of working with Marcos and Alex for our installation. Both guys were so nice and polite. Its so nice to have efficient heat and we look forward to AC this summer. Doni made this process as easy and smooth as possible. Even when things came up in shipping, she kept us informed. This was a great company to work with.


Having my AC serviced is like having your car worked on. I don't know if the work really needs done. I trust Jose, longtime THERMALL technician, to be honest with me. Now I don't have to worry whether a repair needs done or not. I am turning all my rental units over to them for service.
