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+

We appreciated same day service on our air conditioner issue. Josh was knowledgeable, explaining our options, and not high pressure. Within an our our unit was up and running. We will definitely use Interstate Heating again!

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.

We were very pleased with Interstate Heating, and just wanted you to know what reliable, efficient young men you have in your employ. – Ron & Marilyn W.

Your installers were top notch and your company did everything they said they would. I have received rebates and was glad that your company made it so easy to get them. I will highly recommend your company to anyone I know who needs new heating or air-conditioning equipment.

Our Carrier® air conditioning unit lasted for 34 years without service, which is quite remarkable. This experience, as well as high ratings by Consumer Reports, made the selection of another Carrier our first choice. We are looking forward to the efficiency of our new Carrier heating and cooling system. Interstate’s installation of these units was performed in a professional and timely manner.

I have been a customer of Interstate for many, many years—I think I bought my first system from you in the late 80s or early 90s. You have an awesome company with awesome people working for you.

I especially wanted to compliment your team because I have called twice since last week’s installation and am so appreciative of all the people I have worked with—I hope they do not feel I am being a bother.

I have always recommended Interstate to anyone looking for heating or cooling solutions, and I just wanted to thank you and the entire Interstate group of people for being so good at what you do. Thank you so much and please let the people who worked on my systems in the past week know that.

Everything is good—the two men who were here were the most pleasant workers I have ever had come over. Thanks!!

I just wanted to let you and Interstate Heating know that the crew you sent to do my furnace install did a fantastic job. They were very prompt and quick, did a professional job, and really seemed to be enjoying their work. On a scale of one to 10, I would give them a “10”. And this new furnace is really quiet—what a nice change compared to my old one.
