Hot or Cold Problems?

An American Home Comfort Study (AHCS) reports that 67 percent of homes in the U.S. have a room that's too hot in the summer or too cold in the winter. It's a common problem with ducted forced air systems - one that can be solved with a Mitsubishi Electric system installed by our pros at Official Heating & Cooling.

  • Wireless control unit senses the temperature throughout the room and makes automatic adjustments.
  • Installation is as simple as mounting units, connecting the refrigerant lines and making a few electrical connections.
  • No ductwork required, so installation is fast and doesn't require any messy renovation.
  • Options for single rooms, multiple rooms or your entire home.
