Air Conditioning Question: How Does Ductless AC Work?


If you’re in the market for a new AC, ductless technology is an innovative way to cool your home efficiently. Installing a ductless AC system is a great solution to energy loss associated with ductwork. It may also be able to help prevent moisture and allergy problems common in homes with ductwork. In this post, Raleigh Heating & Air would like to show new and current clients about how this technology works, so that they can make informed decisions when it comes to choosing a new AC system.

Ductless AC has two major components: the indoor air handlers that are installed high on the wall or in the ceiling, and an outdoor unit, which houses the condenser and compressor. They are attached by flexible refrigerant piping and electrical lines that run behind the walls to each of the indoor units, and these lines are connected to the outdoor unit. This separation allows for quieter operation of the entire system. The air handler blows the cool air into the living space, extracts hot air, and pumps it back to the outdoor unit, along with any condensation that may have built up.

The advantages of ductless AC are extensive:

  • No air ducts. The US Department of Energy estimates that 25% to 40% of cool air can be lost within ductwork that has gaps, cracks, and loose joints. Faulty or damaged ductwork requires maintenance and repair. By sidestepping ductwork entirely, ductless AC avoids many of its issues.
  • Energy efficiency. Ductless AC tends to offer greater energy efficiency than conventional systems. Many of the more recent models have SEER (Seasonal Energy Efficient Ratio) ratings of up to 23.
  • Zone control. Ductless systems allow you to customize your living space by using different air handlers for various parts of your home. You can set one room at 70 degrees Fahrenheit, while keeping the bedroom off until you go to sleep. This allows for efficient cooling as well.

We hope this brief guide helps you understand how ductless AC works as well as its advantages. If you need air conditioning installation in Raleigh, NC, call Raleigh & Air today!
