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

August 18, 2017

Most homeowners are acquainted with central air conditioners.

Mini-split systems are a kind of ductless heating and cooling. In place of delivering conditioned air to the total home via a network of air ducts, they heat and cool a lone room at a time. This delivers more direct temperature control, increasing comfort and energy efficiency.

How Do Mini-Split Air Conditioners Work?

Mini-splits most closely resemble heat pumps in the way they run. Both models of equipment offer electric cooling, just like an air conditioner. This involves using refrigerant to extract heat from inside a building and exhausting that warm air outside. Then, a reversing valve permits the system to run backward, heating your house in the winter by pulling heat from outdoor air and bringing it inside.

The main distinction between mini-splits and heat pumps is that mini-split systems don’t need ductwork. As an alternative, the indoor unit has a built-in air handler, which is installed on the wall or ceiling in the room you are looking to heat and cool. Copper tubes, wiring and a condensate drain line connect to an outdoor condensing unit through a little conduit in the wall. This exterior component looks similar to an air conditioner or heat pump condenser.

More than one indoor unit can connect to a single outdoor condenser, permitting you to heat and cool your total home with this system if desired. This configuration also makes zoning practical, a very coveted feature that lets you choose when, where and how much you heat and cool individual areas.

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

    Ductless mini-splits are very effective systems, but you may still be thinking why you would want to select it over a common furnace and air conditioner. Here’s why a growing number of Austin homeowners are getting ductless mini-splits:

    • Avoid the drawbacks of ductwork: By delivering heated and cooled air directly, air doesn’t move through cracked air ducts on its way to each room. This can save you as much as 30 percent on your heating and cooling bills. Also, if your house doesn’t already have ducts, you avoid the inconvenience and expense connected to adding them.
    • Choose the best temperature for every room: With zoned heating and cooling from a ductless mini-split, you can keep an office refreshing while maintaining a comfortable nursery—all while optimizing energy efficiency.
    • Save money and energy by not heating and cooling unused areas: Shutting supply registers in a central HVAC system can throw it off kilter, putting strain on the equipment and negating any likely savings. But with individual air handlers in all rooms, you can heat and cool particular spaces only when you need them.
