Energy Efficient Heating and Cooling

Most homeowners think that in order to stay cool in summer and warm in winter, they’ll have to suffer with high utility bills. Mitsubishi Electric cooling and heating systems can’t control utility prices, but they can control your energy consumption.

Mitsubishi Electric’s systems employ user-friendly wireless hand-held, wireless wall-mounted controllers which deliver precision control to provide pinpoint comfort very efficiently. Zone control coupled with personal control equals all-around energy savings.

Mitsubishi’s quiet and powerful systems have three components: an indoor unit, an outdoor unit and the remote controller. Because they don’t require ductwork, these systems are the perfect solution for heating and cooling older buildings not designed for central heat and air, or for smaller spaces such as, but not limited to, individual bedrooms, sunrooms, classrooms, or computer rooms.

The Systems Are Far More Efficient Than Traditional HVAC Systems:
• Homeowners report an instant improvement in their electric bills
• The units are up to 40 percent more efficient than window air conditioners
• They do not waste energy starting and stopping all day like traditional heat pumps
• The systems use only the precise amount of energy needed to maintain comfort
• No energy is wasted cooling or heating unoccupied rooms
• Many of our systems are ENERGY STAR qualified
