Ductless Heating and Cooling Systems. What is a ductless mini split system?

Ductless mini splits system provide a flexible solution for indoor temperature management and are a good alternative to central, forced air systems when installing ductwork is neither feasible nor cost-effective. They provide an excellent option for remodels, room additions and as a supplement to existing HVAC systems.

Mini Split Heating and Cooling Systems. Comfort Zones.

Unlike forced air systems which distribute either warm or cool air throughout an entire house via ductwork, ductless systems manage environments individually with remote, handheld thermostats that control the temperature and air flow for each room or “zone.” In multi-unit ductless systems, which feature a single outdoor condenser connected to multiple indoor units, the heating or cooling is directed precisely where it’s needed, with less energy wasted to heat or cool unoccupied areas. This “zoning” capability also means temperatures can be simultaneously set according to individual preference, with one room warmer or cooler than another, as desired.

Mini Split Heat Pump System. Energy Efficiency.

Because they do not rely upon long stretches of ductwork (which can often be leaky) to deliver heated or cooled air, ductless systems are generally more efficient overall. In fact, distribution energy loss in typical forced air systems has been estimated to be as high as 40%, while estimates for energy loss in ductless systems range from 1% to 5%. Whereas typical systems generally cap out at 18 SEER, ductless systems, most of which are ENERGY STAR® qualified, can achieve up to 26 SEER*, greatly reducing utility bills. Additionally, because indoor environments can be managed by individual zone, less energy is wasted heating or cooling unoccupied areas.

Split HVAC System. Quiet Operation.

Because its noisiest component – the compressor – is installed outside and can be placed up to 100′ ** away from the indoor unit, ductless mini splits are much quieter. Additionally, the rumbling ductwork noises often associated with typical, forced air systems is missing in ductless systems whose controlled air distribution is barely audible on the low setting.
