Eric serviced our air conditioner; outstanding. Our system is significantly more efficient now that it's clean. Tristan was amazing. He advised me to close vents/redirect air to the rooms that needed more heat and to leave on the fan to protect our HVAC system: : : he did suggest adding a line to the basement to give more heat as well which we will likely do. He was an extremely knowledgeable, skilled and kind service man : thank you-Julianne
Excellent service. Knowledgeable and caring serviceman!!

The technician was polite and friendly. He explained the process and results. Would recommend to my friends.


“Our furnace didn’t appear to be running properly and there was a burning smell coming from the vents. Called Interstate at 3:30pm and a very knowledgeable service rep was at our home by 4pm! After determining the cause and weighing options of repair or replacement, we made the decision to replace. This was on a very cold winter day/ night. A new furnace was installed the very next day (arrival at 7:30 am) and completed in a timely manner. All employees were very kind, answered any questions and knowledgeable. I can’t thank them enough for getting out heat up and running!”

“From the first phone call to your company to the good by to your service team ant the end of the day after our install, all experiences were absolutely wonderful. We had both an install of a new a/c and gas furnace. Sam and Jason were extremely friendly and professional. Our salesperson Grant was a pleasure to work with. He explained all the details of the systems; no surprises; very good pricing. I would highly recommend Interstate to all my friends and family.”
