Josh and Noah were on time. Courteous. Efficient in diagnosis and repair. They were also transparent that the furnace was very old and offered options for future consideration. No high pressure. Just matter of fact realities of a 40yo furnace. I was appreciative and will use Interstate in the future.
Response from the owner:Hilary, what an amazing review. Thank you for sharing your experience with Josh & Noah, management loves to hear that the techs are going above and beyond for our customers. Interstate Heating Co., Inc Sussex | Colgate | Brookfield | Repair

Dave, the new system is super quiet—I can hardly tell it’s on. Thanks for the great job. -Steffen W.

I really appreciate your excellent personal service, especially coming to my house with the usage instructions after the equipment was installed. This is the reason we have recommended Interstate to two friends—one for a new air conditioner and furnace and the other for your maintenance services. In fact, we gave you and Interstate a perfect “10” on Carrier’s survey.

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

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!!

-Mary

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.
