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.

“Eric came early (yay!) and quickly determined the problem was that my new air filter that was too restrictive, causing a short cycle and the associated heating problems that go along with it.
He replaced the filter and the problem was resolved.
They should all be this easy!”

“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!”
