Great experience today. A/C problem diagnosed, part was on board. Chris fixed unit and A/C works great. Chris checked that my part was under warranty. Price was competitive but service often outweighs the price. Thank you Chris and Interstate
He was very thorough and fixed the problem in a timely manner. He also left the area beautifully clean when he was done. He was also very professional.
Great service from the young men. Good group of guys. Very friendly and skillful.

Their technician Chris was punctual, friendly, and professional while he diagnosed my furnace issue and performed annual maintenance. Would recommend him to everyone.

“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.”
