Hands down the best HVAC service I've ever experienced. They have done multiple install and repair jobs and maintenance. From the owners to the admin staff to the techs that come out, they are professional, courteous and timely. Their tech named Jesus is the best!

Everyone who helped us through the whole installation from Paul and Terri at the beginning to James and Alex with the installation were fantastic.

Jose ALWAYS takes great care of our 16 year old geothermal heat pump system. We are in great hands with Jose. Thanks

I cannot possibly say enough good about Thermall! From my first conversations with office employee Terri, to the estimator, to the two lead installers, James and Tim, this company has displayed a unique combination of absolute professionalism and efficiency, while at the same time being flexible, kind, and compassionate.
I had been wanting to go from heating my 138-year-old house with a free-standing gas stove, and cooling it with two window rattlers — to a new energy efficient mini-split ductless heat pump for quite a while, and finally made the decision that this was the year. I wasn't sure which company to pick, so I called several. Thermall responded politely and immediately, and so won my business. And it was wonderful dealing with them every step of the way til my new system was up and running.
James and Tim were so fast and efficient, and somehow still had time to cheerfully answer every one of my endless questions ;) It was actually a joy to have them in my house!
I will absolutely recommend Thermall to anyone having heating and cooling (HVAC) work done in the future!


Very polite and professional with much respect for the customer


Excellent HVAC service. Jose took the time to fix our issue and explain what was wrong. We appreciated his thoroughness and kindness.

Awesome company! Great products. Very professional.

Thermall is great! We received a detailed quote and answers to all our questions before our heat pump and duct installation. Technicians always call to confirm their arrival time, and are always prompt, friendly. and professional. I love that they put on shoe covers before entering the home! We feel we get great value from Thermall. We will continue to be loyal customers and to recommend Thermall Heating & Cooling to others.
