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!!

“I just wanted to say that Ethan Lipske was amazing. He found the problem with our AC unit quickly and spent the time to check everything else out too. He made sure he wore the booties inside our house and was the ultimate professional. I would recommend Ethan and your company to anyone.

Thank you Ethan!”

“Chris Carne came out in response to our call about an AC unit that wasn't working properly. He was extremely personable and professional, and quickly diagnosed and fixed the issue. I'm glad I called a hometown expert, and would recommend Interstate to anyone who needs HVAC service.”

“Ethan got the air up and running with a part but it is an older unit and we may decide to have a new unit installed. He gave us options and we appreciate that! Excellent communication and very skilled!”
