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.

  • Auto-Schedule

    With Auto-Schedule, there’s no confusing programming to worry about. Simply adjust the temperature to get comfortable anytime you like using the Nest app or on the thermostat itself, and it will learn your preferences over time.

  • Auto-Away

    When Nest senses that you’re away, it will automatically turn itself down so you don’t have to remember to do it yourself every time you leave. Upon your return, Nest will automatically return to your regular temperature schedule.

  • Energy History

    No one looks forward to getting their energy bill. It seems to go up and down, and often you have no idea why. But since heating and cooling your home accounts for half of your energy bill, minor adjustments to your temperature settings can make a significant impact on your wallet.

    You’ll see the Leaf when you choose a temperature that saves energy. It guides you in the right direction.
