Ductless Systems

Trane®/Mitsubishi Electric is the top selling brand of zoned air conditioning and heating systems, and you will enjoy cleaner air and superior control of cooling, heating and your monthly energy bill. In addition to being quiet, intelligent and efficient, our systems provide extraordinary service life for a lower cost of ownership.

The essential components of a zoned air conditioning and heating system are the outdoor unit, the indoor unit and the smart comfort controls. The system operates by transferring heat to and from an outdoor unit to one or more indoor units. The units are connected by pipes containing refrigerant, a substance that absorbs heat. 

In cooling mode, the refrigerant absorbs heat inside the home and produces colder air by transferring refrigerant from the indoor units to the outdoor unit, where the heat is expelled. 

In heating mode, the process is reversed and the refrigerant absorbs heat outside of the home and provides warmth by transferring the refrigerant from the outdoor unit to the indoor units. This method of heat transfer — which works even in freezing weather — is powered by electricity and is much greener than conventional systems that burn fossil fuels during heating. 

The outdoor unit is equipped with an INVERTER that enables it to quickly change the amount of power it uses and the amount of refrigerant it transfers to and from the indoor units. With the INVERTER, the outdoor unit only uses the precise amount of power needed to reach each zone’s preferred temperature.

With single-zone equipment, one outdoor unit connects to one indoor unit. This option is ideal if you only need cooling and heating in a single space. 

With multi-zone equipment, one outdoor unit can connect up to eight indoor units. This option is perfect if you need cooling and heating in multiple spaces with different functions, such as a nursery versus a kitchen or an office versus a conference room.
