Key Takeaways

  • Ductless AC units deliver cool air directly into rooms without the need for an elaborate ductwork system.
  • They are energy-efficient units that allow zonal temperature control.
  • Ductless AC units are more expensive than conventional central air conditioning systems.

What Is a Ductless Air Conditioning Unit?

A ductless air conditioning unit is an HVAC system designed to cool the air in an indoor space without pushing air through a network of ducts.

Homeowners in Phoenix, AZ, choose ductless air conditioning units when constructing ductwork to accommodate a forced air system is not realistic.

How Do Ductless AC Units Work?

Ductless AC units operate on largely the same principles as central air conditioners. They feature an indoor unit that blows warm air from your home over cold evaporator coils. The refrigerant running through the coil absorbs the heat and transfers it to the outside unit, which has the condenser coils.

The process continues for as long as the system is working, pulling heat out of your indoor air and keeping your indoor space cool. The cool air comes directly from the indoor unit instead of through any vents.

One important thing to note about ductless AC units is that it’s possible to have up to four indoor units connected to one outdoor unit. This provides homeowners with a level of flexibility that is highly unlikely with standard forced air systems.

It’s one of the reasons many people start asking, “How do ductless AC units work?” in the first place.

The Advantages of Ductless AC Units

Now you know the answer to, “How do ductless AC units work?” you’ll want to know the pros and cons. The benefits of choosing a ductless AC unit over a standard split system include:

  • Easy installation. Ductless air conditioning units are easy to install. Installers only have to mount the indoor and outdoor units and run the electric and refrigerant lines that connect both of them. There’s no reason to install new ductwork.
  • Zoned cooling. Ductless AC units offer unparalleled home comfort because they can support multiple indoor units that have distinct remote-control systems. People in different rooms can decide what temperatures work best for them. There’s no need to endure uncomfortable central temperatures.
  • Improved energy efficiency. Ductless air conditioning units are energy efficient because they don’t heat unoccupied spaces. They also don’t lose 20%-30% of the conditioned air to the ductwork system. Modern ductless systems also feature variable speed compressors that ensure more granular control over cooling cycles.

The Disadvantages of Ductless AC Systems

Ductless AC systems are not without downsides. Some of the disadvantages include the following:

  • More expensive equipment. Ductless systems are generally more expensive than central air conditioning units. The long-term energy savings from using these units will balance things out over time, but that upfront investment is surely something to consider.
  • Aesthetic concerns. The indoor units for ductless AC systems sit boldly on the wall. This can affect your interior décor — especially when you consider the fact that most of them only come in white, beige, or gray colors.
  • More maintenance work. You need to clean the smaller filters in these units more frequently to maintain your indoor air quality.
