Josh and Noah were on time. Courteous. Efficient in diagnosis and repair. They were also transparent that the furnace was very old and offered options for future consideration. No high pressure. Just matter of fact realities of a 40yo furnace. I was appreciative and will use Interstate in the future.
Response from the owner:Hilary, what an amazing review. Thank you for sharing your experience with Josh & Noah, management loves to hear that the techs are going above and beyond for our customers. Interstate Heating Co., Inc Sussex | Colgate | Brookfield | Repair

“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.”
