All About Mini-Split Air Conditioners: What They Are and How They Work

August 18, 2017

Most homeowners are most familiar with central air conditioners.

Mini-split systems are a kind of ductless heating and cooling. Instead of delivering conditioned air to the complete house with a network of air ducts, they heat and cool a lone room at a time. This provides more direct temperature control, improving comfort and energy efficiency.

How Do Mini-Split Air Conditioners Work?

Mini-splits most closely resemble heat pumps in the way they run. Both kinds of equipment deliver electric cooling, just like an air conditioner. This requires using refrigerant to draw out heat from inside a building and discharging that warmth outside. Then, a reversing valve permits the system to work backward, warming your residence in the winter by pulling heat from outdoor air and bringing it inside.

The biggest difference between mini-splits and heat pumps is that mini-split systems don’t have to have ductwork. Instead, 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 link to an outdoor condensing unit through a narrow conduit in the wall. This exterior component looks much like an air conditioner or heat pump condenser.

More than one indoor unit can link to one outdoor condenser, enabling you to heat and cool your entire residence with this system if wanted. This arrangement also makes zoning feasible, an extremely popular feature that lets you determine when, where and how much you heat and cool specific spaces.

Is a Ductless Mini-Split the Best Option for My House?

Mini-splits are a good solution for most households. Consider these reasons why installing a ductless mini-split may be a good choice for your needs:

  • You can heat and cool an entire home that doesn’t have existing ductwork.
  • You can switch off the heat and air conditioning in unoccupied spaces to save on your utility expenses.
  • Mini-splits provide additional heating and cooling for spaces that are difficult to keep comfy.
  • Use a ductless system to heat and cool a residence addition or sunroom without the hassle of adding ductwork or the inconvenience of having window AC units.
  • Mini split systems are the natural choice for spaces where overhead ductwork is impractical. A few examples might be historic houses, tiny homes, temperature controlled sheds or workshops, or garage conversions.
  • What are the Perks of a Mini-Split System?

    Ductless mini-splits are very capable systems, but you might still be thinking why you would want to choose it over a common furnace and air conditioner. Here’s why more Hurricane homeowners are installing ductless mini-splits:

    • Avoid the hidden issues of ductwork: By giving heated and cooled air directly, air doesn’t pass through leaky air ducts on its way to all rooms. This can save you as much as 30 percent on your heating and cooling expenses. Plus, if your house doesn’t already include ducts, you avoid the hassle and cost connected to installing them.
    • Choose the best setting for each room: With zoned heating and cooling from a ductless mini-split, you can keep an office refreshing while maintaining a comfortable nursery—all while making the most of energy efficiency.
    • Save money and energy by not heating and cooling empty rooms: Securing supply registers in a central HVAC system can throw it off kilter, putting stress on the equipment and negating any potential savings. But with individual air handlers in each room, you can heat and cool particular rooms only when you need them.
