Ductless HVAC systems, also known as mini-split systems, have gained popularity in recent years due to their energy efficiency and easy installation process. Unlike traditional HVAC systems, ductless systems do not require ductwork to distribute air throughout the home. Instead, they rely on two main components: outdoor units and indoor units.

Outdoor Units: The Heart Of Cooling

The outdoor unit is the heart of the ductless HVAC system. It houses the compressor, which is responsible for cooling the refrigerant and pumping it to the indoor unit. The compressor is powered by electricity and uses a fan to pull in air and cool the refrigerant. Once the refrigerant is cooled, it travels through a series of copper tubes to the indoor unit.

The outdoor unit also contains other important components, including the condenser coil, which helps dissipate heat from the refrigerant, and the expansion valve, which controls the flow of refrigerant to the indoor unit.

Indoor Units: Delivering Comfort

The indoor unit is responsible for delivering cool air to the room. It consists of a fan, evaporator coil, and air filter. When the refrigerant arrives at the indoor unit, it passes through the evaporator coil, which absorbs heat from the air. The fan then blows the cooled air into the room.

One of the main advantages of ductless HVAC systems is that they allow for individual temperature control in each room. Each indoor unit is controlled by its own thermostat, which allows you to set different temperatures for different rooms.

In addition to providing cool air, the indoor unit also helps improve indoor air quality. The air filter captures dust, pollen, and other airborne particles, preventing them from circulating throughout the room.
