Great experience today. A/C problem diagnosed, part was on board. Chris fixed unit and A/C works great. Chris checked that my part was under warranty. Price was competitive but service often outweighs the price. Thank you Chris and Interstate
He was very thorough and fixed the problem in a timely manner. He also left the area beautifully clean when he was done. He was also very professional.
Great service from the young men. Good group of guys. Very friendly and skillful.

“Service was good and technician was knowledgeable, neat and on time. My wife an I felt the service charge was outrageous-$640 for 1.5 hours of labor. Before using your company again I will check with other service providers to compare pricing.”

“Dylan. the technician, came to our home to do a yearly check of our air conditioning system. He was a true professional, courteous, and answered all our questions. We were very impressed with his knowledge. He didn't mind that my husband followed him around because he likes to be informed and understand what was happening and what Dylan was finding along the way. We will always request Dylan for any future needs we may have. Thank you.”

“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!”
