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

“Fantastic experience with Interstate Heating. Was referred to them by my dad who had spoken very highly of your guys’ service in home building projects. My wife and I had our furnace go out and your team was quick to come out, assess and quote the project, and install a new, efficient furnace. I am pretty unknowledgeable when it comes to these things, but your team helped me understand what was occurring and made great recommendations on a new product. In addition to doing a great job, the three individuals I dealt with were all very friendly. 5 stars!”

“My remodeled barn I use for an office was 43degrees when I went out to work at 6:45 AM. I called Interstate at start of business at 7:30 AM. Their technician Eric Osterman arrived before 10:00 AM and the furnace was back on line in around an hour. Eric was a total professional and took care of everything. Overall I was extremely satisfied by the friendly, professional support.”

“Superior service on so many levels!
First of all, I was dissatisfied with the company that installed my furnace (in 2018) but needed someone to address an issue that recently arose. I chose Interstate based on the recommendation of a friend and, after was said and done, I was not disappointed.
The first service call revealed that the furnace was, internally, really dirty. Yes, I do regularly clean the furnace filters, but the camera showed that more was REALLY needed. The first serviceman did an amazing job righting this problem, but warned me that replacement might be needed if the furnace cleaning didn’t remedy the issue.
Well, the problem continued so, the following week, I called again. To make a long story short, called at 8 AM . . . serviceman arrived at Noon . . . replaced faulty part . . . and was out the door by 1:00. No service charge, on the second visit, and part had a 50% discount because of furnace warranty. GREAT SERVICE!!!
I did learn something, from this adventure, and that is duct cleaning may have prevented this.
I already have made an appointment, for that service. (I asked Interstate if they could recommend anyone and they supplied me with the name of someone they found reliable.)
VERY HAPPY WITH INTERSTATE’S SERVICE!!”
