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.

“Chris was prompt and professional. He could not fix the leak in the copper pipe leaving the hot water heater. I need to call a plumber for that. He did check out the hot water heater and confirm that it was not leaking.”

“Had our semi annual furnace & a/c inspection on 4/16. Unfortunately old unit was ready to be replaced-repairs wouldn’t be worthwhile accounting for age of unit. Decided on replacement for entire system. Install was smooth and without any hiccups. Installation technicians were professional and informative, cleaned up space well after install was complete.”

“I highly recommend Interstate Heating. Grant was personable and knowledgeable. Installer's were efficient and cleaned up after themselves. I got several estimates and Interstate came in with the lowest price for a new furnace. I have no regrets!”
