Ductless mini-split in Oak Harbor, WA

If you own a home in Washington State, ductless AC can be better than a traditional HVAC system. There are several reasons to consider having a ductless AC system installed in your home.

What Is Ductless AC?

Also known as a mini-split system, a ductless AC system has two components. There is an outdoor unit and an indoor air-handling unit. There is a conduit running between these components that has a refrigerant line, power cable, condensate drain, and suction tubing. Some outdoor units can attach to up to four indoor air handlers.

Heat and Cool Your Home

A ductless AC can also heat your home. In the summer, it moves warm air out of your home and releases it outdoors. In the winter, it moves heat from the outdoors into your home. As such, a ductless AC will completely replace a traditional HVAC system.

Better Energy Efficiency

A ductless AC is more energy efficient than furnaces, air conditioners, and heat pumps. One reason for this is that you’re only heating or cooling a single room instead of your entire house.

Another reason they’re very efficient is that they don’t need ductwork, unlike traditional HVAC systems. In most homes, over 30% of conditioned air is lost through holes and gaps in the ductwork.


You can control each indoor air-handling unit separately. By only heating or cooling rooms that you’re in, you can keep your energy bills down. If one person likes the temperature at 68 and someone else likes it to be 75, you don’t have to waste energy getting your entire home to 68 degrees.

Environmentally Friendly

Ductless AC is friendly to the environment. These systems have higher SEER and EER ratings than traditional HVAC systems. They also use R410A refrigerant, which isn’t harmful to the environment, unlike the R22 refrigerant used by older air conditioners. Operating your ductless AC won’t harm the ozone layer.

Easy to Install

An HVAC company can quickly and easily install a ductless AC system. The installers just need to set up the outdoor unit, drill a 3-inch hole through an exterior wall for the conduit, and install the indoor air-handling unit. Since they don’t use ductwork, you don’t need to spend money on it or have the hassle of getting it installed.

The conduit between the outdoor unit and indoor air handlers can be up to 50 feet in length. This means you can have the outdoor unit installed in a location that is convenient or hidden away.

They’re Quiet

If you don’t like the noise that traditional HVAC systems have in Washington, you’ll love how quiet a ductless AC is. Some make as little as 19 decibels of sound, which is about the same level as someone whispering. If you use a window air conditioner, even the quietest one is around 45 decibels.

Improved Indoor Air Quality

Ductless AC has filters in the indoor air-handling units that purify the air you breathe. The filters remove dust, dirt, pet dander, pollen, mildew, and more. This is especially helpful in Washington households with members that suffer from allergies or asthma.

Low Maintenance

Ductless AC requires less maintenance than traditional HVAC systems. This is in part because you don’t have to maintain ducts. You only need to keep the filters clean and keep vegetation clear of the outdoor unit. You should schedule professional maintenance every spring, so your ductless AC lasts as long as possible and keeps operating efficiently.

Interior Design Options

You have choices in where the interior air-handling unit is located. It can be hung on a wall or suspended from the ceiling. It can also be placed on the floor. Most interior air-handling units are around 7 inches deep and have a high-tech look.
