Chris was awesome! Knowledgeable, friendly, efficient. Thanks!
Thank you for arriving so promptly. You did a fast job at diagnosing the problem and getting us up in running in these emergency conditions.
Technician arrived on time. He was courteous, professional, and check system thoroughly. Turns out thermostat was off.


“I called the morning after a holiday, and Matthew was very helpful in getting us the assistance we needed. Chris was able to arrive a bit early and quickly troubleshoot and identify the exact issues with both our boiler and furnace. He was polite, knowledgeable, efficient, and cleaned up thoroughly after completing the work.

Every time we’ve worked with Interstate Heating, they’ve been responsive and helpful—from the office staff to the technicians. I truly feel they are honest and have their customers’ best interests in mind.”

“Chris Carne was the technician who came to our condo today to repair and service our gas furnace. He did a very thorough testing of the furnace and discovered we had a faulty gas valve. His courteous explanation of what he was doing along with his nice personality made this repair a pleasant experience. We would highly recommend him for any of your service issues.”
