We had Interstate/T-Mark install 2 new electric heat pump forced air units in a home we are renovating. These replaced an old boiler system for heat and allows us to have AC. Duane, Joe and Kevin were friendly and professional. They were easy to communicate with and we appreciated their flexibility with scheduling and the project layout. Overall we feel the new systems will add value and comfort to our home for a good price.

Joey was the tech that came very good man and did much diagnostic work and determined the problem

Joey came with new thermostat and furnace is running great He is very knowledgeable about so many things to do with heating units I would ask for him again if ever needed and would call interstate for any heating or cooling needs Great company

Joey Marrocco was a great technician, Joey got right to work and was hands on and figured out the problem fast. He went above and beyond in the freezing cold snowy weather and got the job done on my mini split unit and got heat back up and running. I would recommend interstate heating to anyone in need of repair or install.
