Great response time when called for service.

When our furnace "died" on New Year's Day, my husband and I waited to call for a repair until Tuesday, January 2nd to call for a repair. Thornton's service man came promptly on Tuesday and repaired the furnace and we once again had heat. We have had Thornton as our HVAC people for the past sixteen years and have always been satisfied with the work they do.

Semi-Annual Service

The tech's are always on time and take care of business very efficiently. All aspects of the service/maintenance is discussed when completed. Have been happy with this service for many years. I have not shopped around for pricing, however the safety and security l feel with this service far outweighs money.

Autumn flip / tune up service

I found him professional & courteous. He did his work as he described, and answered questions intelligently. Some questions were work related and some were curious or 'educate me'. He explained what was done & why it was done. Thanks I rate 4 stars because its hard to be perfect. It was a good appointment.

Thorough and Informative

We are new homeowners and wanted to get our furnace checked out at the start of this fall season. Our technician was respectful of our home, laying down blankets and using booties in our home, the cleaning and checking was thorough, and he patiently answered any and all questions I had as a new home owner. To help ME save money, he recommended I wait until the spring to have my air conditioner checked, though he did look over it. I appreciate his trustworthiness. I am however still waiting to hear back from the company to learn the costs of signing a warrenty with them. I expected to hear back by now which is the only reason for the overall experience being a 4 instead of a 5. But, this does seem to be a 5 start company!
