Guidebook to Mini-Split Air Conditioners: What They Are and How They Work

August 18, 2017

The majority of homeowners are acquainted with central air conditioners.

Mini-split systems are a type of ductless heating and cooling. Rather than giving conditioned air to the complete house with a network of air ducts, they heat and cool one room at a time. This allows more targeted temperature control, increasing comfort and energy efficiency.

How Do Mini-Split Air Conditioners Work?

Mini-splits are most similar to heat pumps in the way they cool. Both styles of equipment offer electric cooling, the same as an air conditioner. This uses refrigerant to draw out heat from inside a building and exhausting that heat outside. Then, a reversing valve permits the system to run backward, adding warmth to your house in the winter by pulling heat from outdoor air and adding it inside.

The largest difference between mini-splits and heat pumps is that mini-split systems don’t require ductwork. As an alternative, the indoor unit has a built-in air handler, which fits directly on the wall or ceiling in the space you want to heat and cool. Copper tubes, wiring and a condensate drain line link to an outdoor condensing unit through a small conduit in the wall. This exterior component looks like an air conditioner or heat pump condenser.

Several indoor units can link to an individual outdoor condenser, permitting you to heat and cool your complete home with this system if desired. This configuration also makes zoning feasible, a very coveted feature that permits you to customize when, where and how much you heat and cool individual spaces.

  • You’ll be able to shut off the heat and air conditioning in unused rooms to save on your heating and cooling expenses.
  • Mini-splits provide added heating and cooling for spaces that are difficult to keep comfortable.
  • Use a ductless system to heat and cool a house addition or enclosed patio without the hassle of installing ductwork or the hassle of relying on window AC units.

  • What are the Benefits of a Mini-Split System?

    Ductless mini-splits are very effective systems, but you may still be wondering why you would want to choose it over a regular furnace and air conditioner. Here’s why a large number of Columbus homeowners are getting ductless mini-splits:

    • Avoid the hidden issues of ductwork: By providing heated and cooled air directly, air doesn’t pass through cracked air ducts on its way to all rooms. This can save you upward of 30 percent on your heating and cooling expenses. Also, if your house doesn’t already use ducts, you avoid the inconvenience and cost connected to adding them.
    • Find the right temperature for every room: With zoned heating and cooling from a ductless mini-split, you can keep an office chilly while maintaining a cozy nursery—all while optimizing energy efficiency.
    • Conserve money and energy by not heating and cooling unused rooms: Closing supply registers in a central HVAC system can throw it off balance, straining the equipment and negating any potential savings. But with individual air handlers in each room, you can heat and cool specific areas only when you need them.
