Understanding How Ductless Air Conditioning Units Work

Ductless air conditioning units are becoming increasingly popular.

Ductless air conditioning units are becoming increasingly popular. These units provide more efficiency and convenience than traditional systems. But how do they work? This article will examine what components make up the system, how it operates, and why people opt for it over other types of air conditioning.

Differences between ductless and central AC units

Ductless AC and central AC units differ in a few key ways. Ductless AC units are more energy-efficient because they don't lose cool air through ductwork and thus have to work harder to cool a space. They're also easier to install since they don't require a network of ducts to service a space. Meanwhile, central AC units are more expensive to install, but they're better at evenly cooling large spaces since they direct cool air precisely where needed.

The components of a ductless AC unit

Ductless air conditioning (AC) units, or mini-splits, have four main components:

  • An outdoor compressor/condenser

  • One or more indoor air handlers

  • A remote control

  • Connecting refrigerant tubing

The outdoor unit contains the AC unit's condenser coils and compressors. The compressors pump the refrigerant through the system while the condenser coils release heat from the refrigerant, cooling it down.

One or more indoor air handlers are mounted on walls or ceilings inside a home. Each air handler contains a fan that blows cooled and dehumidified air into the house.

A remote control allows one to operate the ductless AC unit from anywhere. The remote control also has a built-in timer to turn on or off at specific times of the day.

Refrigerant tubing runs between the outdoor and indoor units, carrying the refrigerant back and forth.

Pros of ductless air conditioning

There are several advantages to using a ductless air conditioner over a traditional central air conditioning unit. Ductless units don't rely on ductwork to distribute cool air throughout the home, which means no heat loss through ductwork. The unit can cool a room more quickly and evenly. Additionally, ductless units are quieter than traditional units, making them ideal for use in bedrooms and other areas where noise may be an issue. Finally, ductless air conditioners are easier to install than traditional units, so homeowners can avoid the hassle and extra expense of installing ductwork.

Cons of ductless air conditioning

One downside of ductless ACs is that they can be more expensive upfront since they require a professional technician. Additionally, ductless air conditioners can be less efficient than traditional units and may not work as well in large spaces. Lastly, ductless air conditioners require regular maintenance and cleaning to keep them working correctly.
