How Does a Ductless Air Conditioner Work?

ductless-mini-split-on-wallYou may have heard that there are choices for ductless heating and cooling systems available. If your first idea of a “ductless air conditioner” is a window unit, then we’re happy to tell you that there is a much better way to send cool air into your home without using ducts. In fact, the development of ductless mini split heat pumps have made window ACs unnecessary for homes. A house without ductwork in it can enjoy cooling in multiple rooms without having to block up a single window with an ugly, inefficient, and limited capacity AC unit.

The Basics of a Ductless Cooling System

So how does an AC system cool multiple rooms without using ducts? The simple answer is that instead of a single indoor air handler and evaporator, a ductless system uses a series of smaller air handlers with evaporator coils that are placed inside different rooms.

The layout is similar to a conventional split system AC—indoor and outdoor units—except with multiple indoor units. The indoor air handlers are mounted up on the walls and connect to the outdoor unit via refrigerant, condensate, and power lines passed through holes behind them. Each indoor unit cools air along its evaporator coil and sends the air directly into the living space. It’s the point cooling of a window air conditioner without all the drawbacks of a window unit.

Heating and Cooling Power

Although there are some ductless mini splits that are cooling only, the majority are heat pumps. This means that when you install one, you receive a heating and cooling system. With only a simple adjustment to the wall units, you can switch the function of the ductless system so that that the air handlers send out warm air.

Other Benefits of Ductless Air Conditioning

Ductless is great for homes that can’t enjoy standard central air conditioning systems because they don’t have space for ductwork. But ductless mini splits have other advantages as well aside from their flexibility and heating/cooling power:

  • Energy efficient: Without ducts that gain and lose heat through their walls, ductless systems have more efficient performance. They also use smaller motors that consume less power.
  • Zone control: You only need to provide cooling to rooms that need it because each air handler can be turned on and off separately from the others. There’s no need to spend money to cool empty rooms.
  • Improved indoor air quality: No ducts means less dust and lint and other debris blown around the house.

Is Going Ductless Right for My Home?

You may already be enthusiastic about having a ductless mini split installed. But if you feel on the fence about making the change, we recommend speaking to an installer. Ductless isn’t right for every home—but the difference a ductless system can make in the right home is substantial.
