Protect your home’s HVAC system with a maintenance plan from ThermAll!
A home’s heating and air system is often the most expensive item in the home. Regular maintenance and cleaning can ensure that you protect your investment and remain comfortable indoors. ThermAll offers plans for your furnace, heat pump, and air conditioner. We provide a thorough inspection and cleaning twice a year, often just as the seasons are changing. This means that you can turn on your heat in the fall and air conditioner in the summer knowing that they will come on and operate perfectly. While this peace of mind is priceless, our maintenance plans are quite affordable. And, while our technician is inspecting your system, if a repair is needed, he comes fully prepared and can often perform the work while still on site. All repairs found during a regular maintenance appointment receive a 15% discount, too. Don’t wait any longer, contact us today to begin protecting your important investment!

  • ThermAll went the extra mile to make sure my new heat pump was installed in the optimum location. They stayed late to get the job done. Very happy with the service.

  • Jose showed to our cabin in not ideal driving conditions (ice) to diagnos why we had no heat from the heat pump. Replaced a part that limped it while ordering a new motor. Motor arrived quickly and he installed it, giving us fantastic results. We monitor the temp remotely, but had failed to 'pay attention ' last couple days. I can honestly say, that motor made such a difference. Both levels are maintaining equal temp which is a first for as long as I can remember.
    We have been using this company for 9 years, this is our 2nd tech, and we couldn't be happier with the service over all. After hours, or not, they here to help, always with a smile.

  • I have several rental units and cannot always handle Air & Heat problems. This is where ThermAll comes in. They do a semi-annual inspection for me that has worked out very well. Have not had any problems since I began using them, so I guess they really do catch the problems before they occur! I have some knowledge of the equipment, but not all the tools to diagnose and catch things before they happen. Additionally, as a regular customer, I will have priority and a discounted price in case of an emergency....
    Thank You TermAll,
