Dylan is a pleasant and professional technician. He called he was on his way and arrived as he said. Interstate Heating also sent a text and email about his arrival; there is also a link provided to a real-time map. He went straight to work and performed a thorough inspection and testing of the furnace. I feel confident we will have a comfortable winter. If you have Dylan come to your house, you too should have a good experience. Dylan, thanks again.

“Eric was very courteous, knowledgeable, and efficient. He figured out the problem quickly and explained how to prevent the same issue again. Thank you!”

“Chris came to our home on time to fix our air conditioner. Interstate called me early in the morning. Interstate was returning my phone call (I had left a message), to schedule a technician to come to my house. Chris showed up at my house on time 4 hrs later to investigate the air conditioner problem. It took him approximately 30 minutes to diagnose and fix the problem. There was a broken piece of equipment called a capacitor. The bottom line is the problem is fixed and cool air was wafting inside my house in approximately 30 minutes. I certainly could not have asked for better service!”

“Response to weekend service call was quick. Technician diagnosed issue and problem resolved. We have experienced great service from Interstate for the past 24 years! Including the original and one replacement AC/Furnace. Could not be happier with Interstate!”

“Chris Carne came at the worst possible time (not his fault) but I had to talk on a live webinar and so I couldn't provide him much context at the time he arrived. He fixed the air conditioner in 30 minutes or less and figured out where everything was on his own. I appreciate his help in an awkward situation.”

“AC unit stopped producing cold air on a very hot day. I called after hours and received emergency service. The Tech (Jason) quickly arrived and fixed the problem. He answered questions and the problem was fixed in about 20 minutes.”

'- Mike M.

“The serviceman was very helpful and explained the workings of the thermostat to me as well as did the work that needed to be done to keep the AC in working order. He came at the time scheduled and was very professional.”
