How a Ductless Air Conditioning System Works

May 18, 2021 | Airconditioning, Commercial, Residential

Ductless air conditioning is one of the most common methods of air conditioning, especially in small homes. As its name implies, it is a system of air conditioning installation that requires no ductwork, but it works in the same way as centralized air conditioning, only it uses no ducts.

Basically, a ductless AC or mini split system is composed of a single indoor unit and one outdoor unit. These two main components are connected by electrical wiring and refrigerant tubing. The indoor unit, which is typically designed for mounting on walls, works to deliver cooled or heated air directly into the room.

Also called a single-zone system, a ductless AC Palm Bay installation is designed to regulate the temperature of one specific area. A homeowner may, however, opt to install a ductless multi-zone system, which is composed of one outdoor unit and up to five indoor units to ensure that the family’s need for warm or cool air for the entire home is served.

In simple terms, both ductless and centralized air conditioning suck warm air from your room and dump it outside. To lower a room’s temperature, ductless air conditioners blow cold air directly into the area it is intended to cool.

A Ductless Air Conditioning Installation has 3 Main Components

1. Blower/Evaporator Unit

This is the indoor unit that’s mounted on the wall of the room it is intended to cool down. The blower/evaporator sucks in warm air from the room, absorbs heat and moisture from the indoor air, and blows cold air back into the room. The evaporator/blower also works to blow out of the room the heat and moisture it has collected by way of the conduit.

2. Conduit

The conduit of a ductless air conditioner serves as the link between the indoor and outdoor units. It is a long, thin cable that contains the refrigerant tubing, the power cable, and a condenser drain.

The conduit supplies both the indoor and outdoor units with electricity. It also serves as a heat and moisture source from your home that passes through on its way toward the condenser.

3. Condenser

The condenser is the outside or external unit of a ductless air conditioning system. It receives the heat sucked by the evaporator from inside your home and dumps it outside into the open space.

That’s basically how ductless air conditioning works.

With that being said, now let’s take up the pros and cons of ductless air conditioner installation.

The Pros

  • Ductless air conditioners are designed to cool a single space or room. For that reason, ductless units are provided with built-in zoning, which means each blower/evaporator can be controlled to provide the room’s occupant with the temperature they desire.
  • Duct leaks are not a problem with ductless air conditioners. This means that with ductless ACs, you can’t lose money and cool air to duct leaks. Home and business owners lose 20 – 30% of conditioned air to duct leaks, according to Energy.gov.  
  • A ductless AC system can allow users to install up to four or five evaporators to a single condenser to cool multiple rooms.

The Cons

Ductless air conditioning requires a higher upfront cost than centralized air conditioning, especially if a user’s home has an existing ductwork.
