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

August 18, 2017

The majority of homeowners are informed about central air conditioners.

Mini-split systems are a kind of ductless heating and cooling. Rather than delivering conditioned air to the total residence via a network of air ducts, they heat and cool one room at a time. This provides more direct temperature control, improving comfort and energy efficiency.

How Do Mini-Split Air Conditioners Work?

Mini-splits are most like heat pumps in the way they run. Both styles of equipment deliver electric cooling, the same as an air conditioner. This requires using refrigerant to remove heat from inside a building and exhausting that warm air outside. Then, a reversing valve enables the system to run backward, warming your home in the winter by extracting heat from outdoor air and bringing it inside.

The biggest distinction 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 mounts directly to the wall or ceiling in the area 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 much like an air conditioner or heat pump condenser.

More than one indoor unit can link to an individual outdoor condenser, enabling you to heat and cool your total home with this system if if you want. This arrangement also makes zoning possible, an extremely attractive feature that allows you to customize 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 a great choice for many households. Consider these reasons why using a ductless mini-split could be a good choice for your needs:

  • You can heat and cool a total house that has no existing ductwork.
  • It’s possible to shut off the heat and air conditioning in unused spaces to save on your utility costs.
  • Mini-splits give extra heating and cooling for areas that are tricky to keep cozy.
  • Use a ductless system to heat and cool a home addition or enclosed patio without the expense of adding ductwork or the hassle of using window AC units.
  • Mini-splits are the ideal choice for spaces where traditional ducts is impractical. A few examples are period homes, 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 may still be thinking why you would want to choose it over a traditional furnace and air conditioner. Here’s why more Sharonville homeowners are using ductless mini-splits:

    • Avoid the drawbacks of ductwork: By delivering heated and cooled air directly, air doesn’t move through leaky 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 house doesn’t already include ducts, you avoid the annoyance and expense connected to putting them in.
    • Select the ideal setting for all rooms: With zoned heating and cooling from a ductless mini-split, you can keep an office refreshing while maintaining a warm nursery—all while optimizing energy efficiency.
    • Use less money and energy by not heating and cooling empty rooms: Closing supply registers in a central HVAC system can disturb it, putting stress on the equipment and invalidating any possible savings. But with independent air handlers in every room, you can heat and cool certain rooms only when you need them.
