Ductless Mini-split

Ductless mini-splits use air handlers and heat pumps to warm or cool air inside your home. The system doesn’t use air ducts because it only cools one room, unlike the central air conditioning units that heat the entire house. Most homeowners in Centerville are embracing ductless mini-split systems because they are energy-efficient. The systems also make homes more comfortable by allowing you to control temperatures using a remote and save on energy bills. Here is a guideline on how ductless mini-split systems work.


Ductless mini-split systems have three primary components. The evaporator or blower unit sits on the walls of rooms the ductless mini-split system serves. They absorb moisture, warm air, and heat from the indoor air and blow cold air into the room. The conduit connects the outdoor unit to the indoor system. It houses the condensate drain, refrigerant tubing, and power cable. The condenser plays an essential role in receiving the heat from indoors and blowing it into the outdoor air.

How Does Ductless AC Work?

Ductless air conditioners function using the heat transfer process. It entails the refrigerant operating in a closed-loop between the air handlers indoors and the heat pump outside. The air handler blows in warm air in each room that heats a refrigerant coolant or fluid. It then evaporates and moves through a line to the heat pump outdoors. Gasses pass through the heat pump after the energy exchange. The ductless mini-split then expels the warmth into the outdoor air. Consequently, it cools down the coolant or refrigerant fluid to return in liquid form that cycles back the air handler to repeat the procedure.

How Does Ductless Heating Work?

How Does Ductless Heating Work?Ductless mini-splits heat your indoor air the same way it cools it, only that it does so in reverse. The heat pump is responsible for the transfer process of moving warmth from one place to another. It moves heat into your home in the winter. The ductless mini-split heat pump draws heat from the outdoors to evaporate the coolant. The coolant then moves to the air handler to transfer the heat into the room from the pumps and refrigerant. The refrigerant condenses and returns to the system’s heat pump.
