How Does Ductless AC Work?

One of the most common questions that we get from our customer, friends and family about our job is how does ductless AC work? It’s a very effective system for cooling your home and the process itself is fairly straightforward. But make no mistake, the technology in a ductless AC unit is state of the art and very impressive. That’s why they’re so efficient and reliable these days.

Essentially, ductless AC systems provide cooling and heating in your home without needing ductwork. The indoor unit that you see hanging on the wall or ceiling has a corresponding outdoor unit. The outdoor unit is called the compressor and carries refrigerant and power to the indoor unit through a small system of pipes. The refrigerant is delivered directly to the indoor unit, which is also called the air handler, typically located on the wall or ceiling of a room in your home. Installation is fairly easy and does not require any major construction or renovating. All that it takes is to drill a small 4 inch hole in an exterior wall that can be used to connect the two units.

If you also want ductless heating, you will need to install a ductless heat pump. These units look and function basically the same as ductless AC units. They supply both heating and cooling.

Here’s an example of how a ductless AC system is connected.

When is it best to use a ductless AC system?

Ductless systems and heat pumps are very useful in lots of situations and can be a great addition or any cooling or heating system in your home. There are several scenarios in which you should consider installing a ductless AC system:

  1. If you have an addition that you need to heat and cool, and don’t want to spend thousands of dollars on installing ductwork.
  2. If you have an attic or a garage space that you want to heat and don’t want to, or cannot install ductwork.
  3. If you live in an old house, where structurally it would be too difficult and expensive to install a new system of ducts.
  4. If your home is relatively small (under 1500 sq. ft.) and ductwork cannot be easily installed.
  5. If you have central heat and AC, but want a supplemental system when temperatures get either too hot or cold. A ductless system can work well in particular rooms of the house that don’t get adequate heating or cooling from the central system.
