So glad I switched to Interstate Heating! Finally, a company that understands my Aprilaire unit and found trouble brewing in my furnace. I asked for a new filter and got it! Dylan was excellent and I could trust what he says.

“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!!”

“One of our thermostats stopped working. We called Interstate Heating and they quickly set up an appointment the very next day. The service man was extremely pleasant and he fixed the issue within an hour. We are grateful for Interstate Heating’s excellent service and quality! They truly respect the customer!”

“Excellent experience … from review of current system, quote process and installation. My election for an install date for both furnaces coincided with an outdoor temperature of minus 4 degrees. All went very smoothly and the house barely cooled at all. A total of 4 installers and an electrician worked the job, and when they left there was nothing left behind for us the pick up.
Recommend Interstate highly, and I’ve been told I’m a tough guy to please.”

“Completely happy they were able to get and install a new furnace same day. We went from no heat to new heat from a new Armstrong furnace!”
