What is Ductless Air Conditioning?

Many different air conditioning systems can provide a cool climate in your home, but different units may work better than others. To find the best system for your needs and home, it’s crucial to conduct thorough research. Ductless air conditioning systems are a great option if you are looking for no hassle, easy installation, and an overall quiet system.

Ductless air conditioning units are freestanding and are installed without requiring ductwork to cool your home. There are two different systems to choose from when considering a ductless air conditioner, including a mini-split and a multi-split.

Weighing Your Options

You’re probably wondering which option is right for you. Both types have their own unique set of benefits.


Multiple outdoor units must be installed to cool your rooms for a mini-split. Each unit is connected to a single room, and the temperature can be controlled for each living area with a ductless air conditioner. If for some reason a unit would stop working, the other units would operate with no issues.


For a multi-split, all units are connected to one outdoor unit. You can have up to eight air conditioners in your home. The temperature in each room is managed by a thermostat that is in one of the rooms. A multi-split system is still considered a mini-split system but typically it has more units inside the home or building.

The Department Of Energy states that Ductless mini-split systems easier to install than other systems and the hook-up between the outdoor and indoor units usually only requires only a three-inch (~8 centimeter [cm]) hole through a wall for the conduit.

The Top 7 Benefits of Ductless Air Conditioning

Ductless air conditioning systems are great for add-on rooms to your home, specific rooms that you want cooled, or cooling a room where the temperature is inconsistent.

Below are the 7 benefits of a ductless air conditioning system.

Quiet system

A window air conditioning unit tends to be noisy when it kicks on. With ductless air conditioning, the compressor is outside the room being cooled, so you won’t even know it’s on!

No ductwork

Ductwork may take days, but a ductless air conditioning system may be functional in a few hours, depending on how many indoor and outdoor units you need. Installation only requires a small hole in the wall to connect the pipe from the interior unit to the compressor unit outdoors.

Allergy control

The filtration technology used by ductless air conditioning units can lessen the dust, bacteria, and pollen in your living space. Ductless systems produce cleaner air in the rooms where they are installed due to filters in each indoor unit. The air filter helps trap unwanted particles from being disbursed throughout your home.

Energy efficient

Who doesn’t love to save on their monthly bills? With ductless air conditioning, you’ll save money on your utility costs and use less electricity than most central heating and cooling systems. This is because of zoning. Ductless systems don’t waste energy cooling unoccupied spaces in your house. Over time, this conserves energy.

Customizable to fit your needs

Ductless systems have an astounding range of power capacities. They can cool a single room or an entire smaller home. If you have a larger home and want to install multiple units, one in each room, it’s possible. If you want to keep one room at 60 degrees and another at 70 degrees, that is also something you can achieve with ductless air conditioning systems.

Low Maintenance

Around once a month, the filter on each indoor unit should be taken out and cleaned. A Chas Roberts expert can check the refrigerant pressure and flush the condensate pipes once a year.

Two in One Unit

You get a heating and cooling system with a ductless mini-split system. The air conditioning will be more beneficial in Arizona, but you never know. Heating your home may be required on a few colder days.

Things To Keep In Mind

While the ductless air conditioner has many significant advantages, it also has some disadvantages, including cost, the overall look of the unit, and existing ductwork.

The initial equipment cost is expensive compared to a ducted air conditioning unit. If you want multiple systems throughout your home, that can increase the price. Another factor to keep in mind is the look of the unit. They can take up some space on your walls and, to some people, can be an eyesore when you walk into a room. If you are not one to care about décor and comfort is the number one thing on your mind, this unit will be perfect for you.

If you already have existing ductwork throughout your home, it may be more beneficial and cost effective to stay with a central system. In addition, if you have a larger home (2,500 square feet and up) it might be best to go with central air conditioning.
