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 form of ductless heating and cooling. Instead of providing conditioned air to the total residence via a network of air ducts, they heat and cool a lone room at a time. This provides more advanced temperature control, improving 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 offer electric cooling, just like an air conditioner. This uses refrigerant to extract heat from in a building and exhausting that warmth outside. Then, a reversing valve allows the system to operate backward, warming your residence in the winter by removing heat from outdoor air and bringing it inside.

The biggest distinction 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 space you wish to heat and cool. Copper tubes, wiring and a condensate drain line join 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.

Several indoor units can connect to one outdoor condenser, enabling you to heat and cool your entire residence with this system if if you want. This set-up also makes zoning practical, a highly coveted feature that permits you to determine when, where and how much you heat and cool distinct areas.

Is a Ductless Mini-Split Right for My Residence?

Mini-splits are a fantastic choice for the majority of households. Consider these reasons why getting a ductless mini-split may be a smart choice for you:

  • You can heat and cool a complete home that lacks existing ductwork.
  • You’ll be able to shut off the heat and air conditioning in unused areas to save on your utility bills.
  • Mini-splits provide extra heating and cooling for areas that are hard to keep comfortable.
  • Use a ductless system to heat and cool a home addition or sunroom without the hassle of installing ductwork or the inconvenience of having window AC units.
  • Mini split systems are the ideal choice for spaces where traditional ducts is impractical. A few examples are historic houses, tiny homes, temperature controlled sheds or workshops, or garage conversions.
  • What are the Pluses of a Mini-Split System?

    Ductless mini-splits are extremely efficient systems, but you might still be wondering why you would want to select it over a regular furnace and air conditioner. Here’s why more Girard homeowners are using ductless mini-splits:

    • Avoid the hidden issues of ductwork: By delivering heated and cooled air directly, air doesn’t go through cracked air ducts on its way to each room. This can save you as much as 30 percent on your heating and cooling expenses. Plus, if your home doesn’t already use ducts, you avoid the annoyance and expense connected to installing them.
    • Find the right temperature for each room: With zoned heating and cooling from a ductless mini-split, you can keep an office chilly while maintaining a comfortable nursery—all while maximizing energy efficiency.
    • Save money and energy by not heating and cooling unused rooms: Securing supply registers in a central HVAC system can throw it off kilter, putting strain on the equipment and canceling any potential savings. But with detached air handlers in every room, you can heat and cool specific areas only when you need them.
