Dylan is a pleasant and professional technician. He called he was on his way and arrived as he said. Interstate Heating also sent a text and email about his arrival; there is also a link provided to a real-time map. He went straight to work and performed a thorough inspection and testing of the furnace. I feel confident we will have a comfortable winter. If you have Dylan come to your house, you too should have a good experience. Dylan, thanks again.

“Problem:furnace shutting off before achieving desired temperature. Technician spent 30 minutes trying to repeat the problem but couldn’t. He set blower speed up a small amount to keep furnace from overheating.hopefully this solved the issue”

“Our furnace didn’t appear to be running properly and there was a burning smell coming from the vents. Called Interstate at 3:30pm and a very knowledgeable service rep was at our home by 4pm! After determining the cause and weighing options of repair or replacement, we made the decision to replace. This was on a very cold winter day/ night. A new furnace was installed the very next day (arrival at 7:30 am) and completed in a timely manner. All employees were very kind, answered any questions and knowledgeable. I can’t thank them enough for getting out heat up and running!”

“From the first phone call to your company to the good by to your service team ant the end of the day after our install, all experiences were absolutely wonderful. We had both an install of a new a/c and gas furnace. Sam and Jason were extremely friendly and professional. Our salesperson Grant was a pleasure to work with. He explained all the details of the systems; no surprises; very good pricing. I would highly recommend Interstate to all my friends and family.”
