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

August 18, 2017

The majority of homeowners are most familiar with central air conditioners.

Mini-split systems are a type of ductless heating and cooling. Rather than delivering conditioned air to the complete house with a network of air ducts, they heat and cool one room at a time. This provides more advanced 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 operate. Both types of equipment provide electric cooling, just like an air conditioner. This requires using refrigerant to draw out heat from within a building and issuing that warm air outside. Then, a reversing valve permits the system to operate backward, adding warmth to your house in the winter by pulling heat from outdoor air and bringing it inside.

The main 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 mounts directly to the wall or ceiling in the area you wish to heat and cool. Copper tubes, wiring and a condensate drain line connect to an outdoor condensing unit through a small conduit in the wall. This exterior component looks like an air conditioner or heat pump condenser.

More than one indoor unit can connect to one outdoor condenser, allowing you to heat and cool your complete house with this system if wanted. This set-up also makes zoning possible, a highly attractive feature that lets you determine when, where and how much you heat and cool distinct spaces.

Is a Ductless Mini-Split the Best Choice for My Residence?

Mini-splits are an excellent option for many households. Consider these reasons why getting a ductless mini-split could be right for your home:

  • You can heat and cool a complete home that doesn’t have existing ductwork.
  • You’ll be able to switch off the heat and air conditioning in empty areas to save on your energy expenses.
  • Mini-splits give added heating and cooling for areas that are difficult to keep comfy.
  • Use a ductless system to heat and cool a home addition or enclosed porch without the expense of installing ductwork or the annoyance of using window AC units.
  • Mini splits are the ideal choice for spaces where overhead ductwork is impractical. A few examples are 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 highly effective systems, but you may still be considering why you would want to select it over a common furnace and air conditioner. Here’s why more Louisville homeowners are getting ductless mini-splits:

    • Avoid the hidden issues of ductwork: By delivering heated and cooled air directly, air doesn’t move through leaky air ducts on its way to every room. This can save you upward of 30 percent on your heating and cooling costs. Also, if your house doesn’t already use ducts, you avoid the annoyance and cost that comes with adding them.
    • Find the ideal temp for each room: With zoned heating and cooling from a ductless mini-split, you can keep an office cool while maintaining a warm nursery—all while making the most of energy efficiency.
    • Conserve money and energy by not heating and cooling vacant rooms: Closing supply registers in a central HVAC system can throw it off balance, putting stress on the equipment and canceling any potential savings. But with independent air handlers in all rooms, you can heat and cool particular spaces only when you need them.
