Interstate Heating replaced our 21 year old furnace and a/c with a Carrier cold climate heat pump and high efficiency gas furnace. I worked with Tom from sales to get a good balance of price and efficient equipment. He did a great job working through different options to show different price points. The install crew also did a great job. They laid down drop cloths to protect the wood floor and carpeting and they cleaned up well after the work was complete. The equipment installation and duct modifications look very well put together.

The pro did an excellent job of diagnosing the problem with my furnace.Im not happy with the warranty on the furnace, the furnace is only a little over one year old and the Carrier warranty only covered the cost of parts and not the labor which was $489.55! It seems a warranty should be better than this for a relatively new furnace. Also it seems that the problem with the furnace is one that occurs frequently and may occur again. It seems to me that the thermostat recommended by your company from the furnace company has more issues than my Nest thermostat which governs my other furnace just fine. If I require further service, i think changing the thermostat seems to be a better plan!

Interstate was amazing. From the empathy and friendly manner my initial call was handled, to the thorough way Eric explained what was happening, to our install, everyone was super polite, respectful, and did great job. Victor and his partner for the install laid down tarps and wore shoe covers to keep the pathway clean and even took extra steps to clean up the rust stains on the floor from the old unit. They also took the time to help us get familiar with our new thermostat.

Dylan, was very professional. Tried to break the cost of the new part gently to me. But over $1, 500.00 is a hard number to swallow for a 11 year old furnace. I think carrier is off of my list for my next furnace and AC.

Fall Update: Eric was back for our heating maintenance. He discovered a wearing component which would shut the system down due to safety. No one wants to be cold in January. Eric quickly replaced it avoiding a winter emergency service call. Great job Eric!Eric Osterman was recently to our home for our annual A/C system preventative maintenance. He was very professional, thorough and answered my questions in a manner I found easy to understand. The good news was Eric discovered and quickly replaced a key component in the outside compressor that would have eventually failed preventing the home from being cooled. That is the value of their preventative maintenance program. Thanks Eric!!!

“Interstate is a great company they are responsive and always do a great job for us. The Company takes care of whatever problem we may have as quickly efficiently and reasonably as they are able. You cant ask for more. Most times we get the same people who will come to do our work. In our case it’s normally Kevin for the heating and his Son for the cooling. They are a great duo both great guys and know our home our systems that are complex and they keep it all running really well with rare visits in between our normal twice yearly maintenance work. Both father and son and knowledgeable polite a pleasure to have in our home great with our dogs and everyone we have dealt with over the years at the company are responsive and personable. All their good work is really appreciated. We built our home about 7 years ago and I would recommend Interstate when designing your new home or maintaining your old home. To find a business these days that appreciate you and are responsive and know what they are doing are becoming a rare thing sadly. So thumbs up to everyone at Interstate and the great job they are doing!!
Thanks!”
