All About 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 kind of ductless heating and cooling. Instead of giving conditioned air to the entire home via a network of air ducts, they heat and cool a lone room at a time. This allows more direct 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 run. Both models of equipment deliver electric cooling, similar to an air conditioner. This uses refrigerant to remove heat from in a building and issuing that heat outside. Then, a reversing valve permits the system to operate backward, heating your residence in the winter by pulling heat from outdoor air and depositing it inside.

The main distinction between mini-splits and heat pumps is that mini-split systems don’t require ductwork. Instead, the indoor unit has a built-in air handler, which is installed on the wall or ceiling in the room you want 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 similar to an air conditioner or heat pump condenser.

More than one indoor unit can link to one outdoor condenser, allowing you to heat and cool your total residence with this system if if you want. This configuration also makes zoning practical, a highly attractive feature that lets you choose when, where and how much you heat and cool specific areas.

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

Mini-splits are a fantastic solution for many households. Think about these reasons why using a ductless mini-split may be a good choice for your home:

  • You can heat and cool a complete house that lacks existing ductwork.
  • You can switch off the heat and air conditioning in unused areas to save on your energy costs.
  • Mini-splits deliver extra heating and cooling for areas that are tricky to keep comfortable.
  • Use a ductless system to heat and cool a house addition or sunroom without the expense of adding ductwork or the inconvenience of relying on window AC units.
  • Mini splits are the ideal choice for spaces where traditional ducts is impractical. A few examples might be historic homes, tiny homes, temperature controlled sheds or workshops, or garage conversions.
  • What are the Pluses of a Mini-Split System?

    Ductless mini-splits are highly efficient systems, but you could still be considering why you would want to choose it over a regular furnace and air conditioner. Here’s why a large number of Memphis homeowners are getting ductless mini-splits:

    • Avoid the drawbacks of ductwork: By delivering heated and cooled air directly, air doesn’t move through holey air ducts on its way to each room. This can save you nearly 30 percent on your heating and cooling bills. Also, if your home doesn’t already include ducts, you avoid the hassle and price associated with adding them.
    • Find the right temp for each room: With zoned heating and cooling from a ductless mini-split, you can keep an office cool while maintaining a cozy nursery—all while making the most of energy efficiency.
    • Save money and energy by not heating and cooling unused rooms: Securing supply registers in a central HVAC system can disturb it, putting strain on the equipment and negating any likely savings. But with independent air handlers in every room, you can heat and cool specific areas only when you need them.
