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

August 18, 2017

Many homeowners are acquainted with central air conditioners.

Mini-split systems are a type of ductless heating and cooling. In place of delivering conditioned air to the total house through a network of air ducts, they heat and cool one room at a time. This delivers more advanced temperature control, enhancing comfort and energy efficiency.

How Do Mini-Split Air Conditioners Work?

Mini-splits are most like heat pumps in the way they run. Both models of equipment provide electric cooling, similar to an air conditioner. This involves using refrigerant to draw out heat from in a building and exhausting that heat outside. Then, a reversing valve enables the system to operate backward, warming your house in the winter by pulling heat from outdoor air and adding it inside.

The largest distinction between mini-splits and heat pumps is that mini-split systems don’t need ductwork. As an alternative, the indoor unit has a built-in air handler, which fits directly on the wall or ceiling in the space you are looking to heat and cool. Copper tubes, wiring and a condensate drain line join 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.

Multiple indoor units can work off of a single outdoor condenser, enabling you to heat and cool your complete home with this system if desired. This set-up also makes zoning feasible, a highly popular feature that lets you determine when, where and how much you heat and cool distinct spaces.

Is a Ductless Mini-Split Right for My Home?

Mini-splits are an excellent option for the majority of households. Think about these reasons why getting a ductless mini-split might be a good choice for your needs:

  • You can heat and cool a complete home that has no existing ductwork.
  • It’s possible to turn off the heat and air conditioning in unused areas to save on your heating and cooling expenses.
  • Mini-splits deliver additional heating and cooling for areas that are hard to keep comfy.
  • Use a ductless system to heat and cool a house addition or sunroom without the hassle of adding ductwork or the inconvenience of relying on window AC units.
  • Mini split systems are the ideal choice for spaces where overhead ductwork is impractical. A few examples might be period homes, tiny homes, temperature controlled sheds or workshops, or garage conversions.
  • What are the Advantages of a Mini-Split System?

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

    • Avoid the drawbacks of ductwork: By providing heated and cooled air directly, air doesn’t pass through cracked air ducts on its way to every room. This can save you nearly 30 percent on your heating and cooling expenses. Plus, if your house doesn’t already use ducts, you avoid the hassle and price associated with adding them.
    • Select the ideal temperature for every room: With zoned heating and cooling from a ductless mini-split, you can keep an office cool while maintaining a comfortable nursery—all while making the most of energy efficiency.
    • Conserve money and energy by not heating and cooling empty 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 independent air handlers in every room, you can heat and cool particular rooms only when you need them.
