Small details mean big things. Guys were super polite, wore shoe covers, didn't bang anything into a wall (careful!) and even got it all set up for me on my phone (to run the furnace temp). Nice, clean, quick.

We have been a long time customer (25 years) and are always satisfied. Today our lower level ac unit wasn’t working properly and they were able to get out to service the unit right away. Technician Erik showed up on time and quickly assessed the problem and promptly fixed it. Will always recommend Interstate Heating and Cooling.
Response from the owner:Thank you, Michelle, for your continued patronage of Interstate Heating. We love to hear our customers are still happy after all these years. We look forward being here for you in the years to come. Interstate Heating Co., Inc Brookfield | Elm Grove | New Berlin | Repair

“Interstate installed my HVAC system in a new construction condo. After living in it for 16 months, I realized I hadn't replaced my filters. I called to have the system checked. Eric found my Aprilaire Humidifier wasn't working because of funky wiring and the filter was not installed correctly.”

“Interstate was absolutely wonderful to work with. They answered any and all questions that I had. (And I had a lot of questions) They gave me information on when the work would take place and had my Carrier Infinity furnace/ AC unit in very quickly. The installation crew was also very knowledgeable and polite. They also helped me with paperwork for a rebate as well. Please note that Carrier is the way to go….. My old Carrier AC unit was 38 years old and STILL working!!!
I was in construction for 37 years and can tell good contractor people. Interstate was fantastic to do business with!”

Dylan is very friendly and knowledgeable. He was able to complete the AC maintenance, re-check the gas leak, and repair the gas pipe where the gas leak was with no problems. Thanks Dylan!”
