Michiana HVAC Products

Our experience allows us to consult with and recommend to our customers unique and individual solutions that will be energy efficient and improve your home or business comfort needs whether that be with a new Air conditioner, Heat pump, Furnace, Blower coil unit, or Indoor Air Quality product. In addition to selling top-quality brands like Lennox, we are proud to have our own Great Lakes brand manufactured in a national facility just for us. We customize them upon installation to meet the specific requirements of each customer and the area in which they live: for example, we install sealed contactors to keep out earwigs and other pests – something not found in many other parts of the country.
