DUCTLESS MINI-SPLITS
Incredible Comfort. Unbeatable Efficiency.
In the winter, a ductless mini-split draws heat from the outside air and circulates it into your home. In the summer, it reverses the process and draws heat from your interior air and releases it outdoors. It also dehumidifies the indoor air as it cools it.

Carrier - Ductless 12000 Btuh Heat Pump Single Zone w/ Basepan Heater
The 38MA*R series ductless split systems are a matched combination of an outdoor condensing unit and an indoor fan coil unit connected only by refrigerant tubing and wires. Extra-Low Temperature Heating Heat output up to 75% of rated capacity down to –22°F (–30°C), so when it’s cold outside, it will be warm inside, making this a primary heat source and eliminating the need for a backup heat source.

How does a Mini Split Work?
The mini split serves as an air conditioner by absorbing heat from indoor air and pumping it outdoors. The mini split contains an indoor coil which, in turn, contains a very cold liquid refrigerant. As indoor air passes over the indoor coil, the refrigerant-cooled coil absorbs heat from the air and so quickly cools that air.
The cooled air cannot hold as much moisture as it did at a higher temperature. The excess moisture condenses on the outside of the coil, resulting in the dehumidification of the air. The cooled, dehumidified air is then forced (by a fan) to circulate throughout the space.
At the same time, the absorption of heat by the refrigerant turns the refrigerant from a liquid into a vapor. A compressor pumps the heat laden vapor through a vapor line to an outdoor coil which discharges the heat extracted from the indoor air. As the heat is discharged, the vapor is cooled and changes back into a liquid refrigerant. The refrigerant is then pumped back through a liquid line to the indoor coil and the cycle is repeated.
The mini split contains a reversing valve which reverses the flow of refrigerant and thus allows the mini split to serve as a heater during cold weather.
A mini split serves as a heater by absorbing heat from outdoor air and pumping it indoors. As the outdoor air passes over the outdoor coil, heat from that air is absorbed by the refrigerant contained inside the coil.
The absorption of heat changes the refrigerant from a low-temperature liquid to a low temperature, low-pressure vapor. The vapor then passes through a compressor where it is compressed into a high pressure, high temperature vapor. The hot vapor then circulates into the indoor coil. As indoor air passes over the indoor coil, it absorbs heat from the coil. The warmed air is then redistributed through the space.
