Components of a Ductless Heat Pump

There are two main components of a ductless heat pump. The outdoor unit and the indoor unit(s).

In the outdoor unit, you have three primary components.

  • Condensing coil: the condensing coil is composed of aluminum fins structured in a lattice-like form. These coils release the heat absorbed by refrigerant to the outside air.
  • Compressor: the compressor is like the heart of the system. It increases the gaseous refrigerant’s temperature and pressure by compressing it so that the thermal process is efficient.
  • Fan: after the refrigerant is compressed and converted into hot gas, it’s circulated through the condenser coils where a fan dissipates air over them.

In the indoor unit, you have an evaporator coil and fan. These units are strategically placed to heat and cool a room or an entire building.

How do Ductless Heat Pumps Work?

Ductless heat pumps consist of an outdoor heat pump and several indoor air handlers. These systems are efficient at both heating and cooling a home, depending on the time of year. In the winter, the heat pump will absorb heat from the air and will distribute it indoors to warm your home. In the summer, warm air passes over evaporator coils, absorbs heat, and then releases it through the outdoor unit to keep your home cool.

Are Ductless Heat Pumps Hard to Install?

No, ductless heat pumps are known for being very easy to install. Installation entails installing the outdoor condenser unit and connecting it through cables to the indoor air handlers. The entire process can take place in as little as a day. As the name suggests, ductless heat pumps are completely ductless so you don’t have to worry about ductwork.
