Also known as mini-split systems, ductless air conditioning cools homes and businesses without ductwork. A ductless system circulates air using an outdoor compressor and an indoor handling unit, which are connected by a line set that transports refrigerant. Warm weather is just around the corner, so get answers to common questions to determine if this energy-efficient method of cooling is right for your home.

An Introduction to Ductless AC

How does it work?

The interior handling unit on a ductless system removes warm air from your home and passes it over refrigerant, which absorbs the heat so cool air reenters the space. The leftover heat gets directed through the line set to the outdoor compressor or heat pump for distribution into the atmosphere. Interior handling units are placed throughout the home as needed.

What does installation involve?

Your HVAC contractor drills a 2- to 3-inch hole on the side of your home to connect the outdoor compressor and the indoor air handler via the line set, which contains copper tubing and electrical wiring.

Next, the compressor and handler are mounted to the outside and inside of your home, respectively, with the handler usually installed higher on the wall for aesthetic reasons. A conduit featuring the power cable, refrigerant line, and condensate drain also gets installed to connect these parts.

What benefits can I expect?

Because ductless air conditioning systems lack traditional ductwork, they improve air quality. Ducts collect pollutants, including pollen, insect remains, dust and dust mites, and pet dander, which are all blown out through vents to circulate through your home. Clogged or leaking ductwork presents efficiency issues as well.

In homes with multiple handling units, family members can fine-tune the comfort level of individual rooms, so a bedroom can be made cooler without using extra energy throughout the rest of the house. You’ll also save money on installation costs because ductless systems don’t take serious effort or time to set up.

How do I maintain a mini-split system?

Clean the air filter once or twice during warm weather depending on factors such as pets and how often you dust and vacuum your home. Follow the manufacturer’s guidelines concerning replacements as well.

Also, check the outdoor unit for leaves, twigs, and other debris before turning it on for the season. Cleaning it as needed and ensuring it’s free of obstructions will help ensure your system works at peak efficiency. Cover the unit with tarp or plastic in the fall to protect it from winter elements.
