Tristan came out to do our annual checkup, re run a wire, and look into some issues with our A/C. He was very personable and friendly. Easy to communicate with. No issues! Tristan was very easy to work with and would recommend he come out for our next visit. Highly recommended! It was a pleasure doing business with Interstate again.

Your company recently installed a new Carrier® furnace and air conditioning system in our home. We were very pleased with the quality of service we received. From David, who oversaw the project, to the entire team helping with this installation, we were most impressed. Everyone was professional, knowledgeable, and extremely courteous, and did an excellent clean-up job when done. The entire job was completed in one day. This is one of the most satisfactory contractor experiences we have had. We will not hesitate to recommend Interstate Heating whenever the occasion arises. -Phillip R.

Good morning, David. I write this message to let you know how pleased we are with your service while having a new furnace and air conditioner installed in our home. Your quick response to our request for an estimate and recommendation, followed by a three-day turn-around on installation, was exceptional. Tod and Brett did a great job in installing the units, they were pleasant to work with, and did an excellent job cleaning up after they were done.

Our air conditioner is working great, and we are always ready to recommend your company to our neighbors. Keep up the great work and thanks so much for your outstanding service.

We wanted to send a note to let you know how pleased we are with our new air conditioning. Our hydronic heat (a boiler) prevented us from having anything but window air conditioning units—until we met you at the home improvement show and you explained what your company could do. The entire process went very well and the vents in the ceiling look as though they’ve always been there. Your staff and electrician were great to work with and they cleaned up as they went along—a huge plus in my book! Our install was in early May and when the warm weather arrived—heaven! No struggling with window units, no taping windows, just comfort at the push of a button. Yours is definitely a company to trust. Thank you again!

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

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!!
