Another installer did shoddy work and our a/c unit developed a serious coolant leak. Our technician found and repaired the leak and serviced our system. He was friendly, helpful and prompt. A+

John and Cal were fantastic-very organized. Great people skills, tidy, systematic in everything they did beginning to end, their work seemed streamlined and impeccable, the clean-up thorough. Tom did a great job selling the process and product options, and expedited a quick installation and solution. The value proposition of a quality product seemed easy to accept when comparing g the choices. He spent time making certain I understood the details and how to explain to my husband who was working in Tennessee for the week.

Last weekend we had a horrible rainstorm. We got 4.8" of rain and lost power for 20 hours. When the power came on at 2:14am, exhausted we went to sleep. When we woke up the house was very warm and humid. I called Interstate Heating Sunday and left a message. Sure enough Monday bright and early we got a call. They sent a technician out same day. Josh quickly discovered it was the transformer in the furnace. It wasn't getting power. So the AC couldn't work. He fixed it so fast! We are back to normal and so greatful. Interstate has been our heating/ac for 24 yrs. Wonderful office staff, great service techs. Thank you Interstate!!
Response from the owner:Hi Mary, thank you for trusting us at Interstate Heating to get you back up and running. It's such great news that Josh got your repair done so quick for your home and got you back comfortable. We're always here when you need us.

“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!”
