The Benefits of a Ductless Air Conditioning System


The standard air conditioning system for homes is known as a split system. This is because the air conditioner is split into two parts, indoors and outdoors. The outdoor unit is the condenser, which contains the compressor, condenser coil, and exhaust fan. It connects to the indoor unit, which consists of the evaporator and air handler, and connects to the duct network that carries the cooled air through the house. 

This isn’t the only way to provide central cooling to a home, however. A ductless mini-split changes the standard split system by connecting the outdoor unit to multiple indoor units. These indoor units are blowers mounted up on the walls that contain a refrigerant coil and blower fan so they can send cooled air directly into rooms, bypassing ducts entirely.

Ductless mini splits aren’t right for all homes, but they offer several advantages to particular homes:

Heating and cooling

Although there are a few “cool only” ductless systems, most are heat pumps. This means you’re not only installing a ductless air conditioner, you’re installing a ductless heater as well.


For older homes that don’t have ductwork designed into them, adding central air conditioning can be difficult, requiring finding places to add ducts. Using a ductless mini split removes this problem: all that’s necessary for installation is to install the unit outside and then place the wall-mounted units in the rooms. One outdoor unit can handle from 4 to 8 indoor units. This flexibility of installation also makes ductless systems great for remodeling a house or putting in an add-on room so there’s no need to alter the ductwork.

Energy savings

Ductless mini splits are among the most energy-efficient types of HVAC systems on the market. They use smaller motors than standard split systems and they do not suffer from any heat loss and heat gain through the walls of ducts. This removes a major source of energy loss that ducted systems suffer from.

Zone control

The indoor wall-mounted units of a ductless mini split can be operated separately from each other. (Each has its own remote control.) You only need to run the units inside the rooms that require heating or cooling. This is an additional way you can save energy and also makes ductless systems perfect for adding to rooms that aren’t connected to the rest of the HVAC system.

Improved indoor air quality

A problem that any ducted system runs into is that ducts collect dust and lint and other debris that circulates through the house. Each time the blower fan of the HVAC system turns on, it sends out a cloud of these indoor pollutants that lower the indoor air quality. Ductless systems don’t have this problem because they have no ducts in the first place. You only need to wipe some dust off their fronts from time to time. Going ductless is great for homes with people who have allergies or asthma.
