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.


“Josh is very nice to work with. He gladly takes time to explain anything you ask him about.
He replaced the heat exchanger in less time than I expected and the furnace is now running fine.”

“Luke was polite and professional as he performed annual maintenance on our gas furnace. Our smart thermostat failed during the process, however. He installed a temporary thermostat and then returned the next day to replace our thermostat with the same model, at no additional charge. I give Interstate Heating 5 stars in both quality work and integrity.”
