Guidebook to 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 form of ductless heating and cooling. Instead of providing conditioned air to the entire home through a network of air ducts, they heat and cool a single room at a time. This provides more targeted temperature control, increasing comfort and energy efficiency.

How Do Mini-Split Air Conditioners Work?

Mini-splits are most like heat pumps in the way they cool. Both types of equipment provide electric cooling, similar to an air conditioner. This requires using refrigerant to extract heat from within a building and issuing that warmth outside. Then, a reversing valve permits the system to operate backward, adding warmth to your home in the winter by pulling heat from outdoor air and adding it inside.

The main 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 space you wish to heat and cool. Copper tubes, wiring and a condensate drain line link 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.

Multiple indoor units can work off of a single outdoor condenser, enabling you to heat and cool your complete house with this system if if you want. This set-up also makes zoning feasible, a very desirable feature that lets you customize when, where and how much you heat and cool distinct rooms.

Is a Ductless Mini-Split the Best Option for My House?

Mini-splits are a fantastic option for the majority of households. Think about these reasons why using a ductless mini-split might be a wise choise for you:

  • You can heat and cool an entire home that doesn’t have existing ductwork.
  • You can turn off the heat and air conditioning in unused rooms to save on your utility bills.
  • Mini-splits provide added heating and cooling for spaces that are hard to keep comfy.
  • Use a ductless system to heat and cool a house addition or sunroom without the expense of installing ductwork or the inconvenience of having window AC units.
  • Mini split systems are the natural choice for spaces where ductwork is impractical. A few examples might be historic 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 capable systems, but you may still be wondering why you would want to choose it over a traditional furnace and air conditioner. Here’s why more Waldorf homeowners are installing ductless mini-splits:

    • Avoid the hidden issues of ductwork: By giving heated and cooled air directly, air doesn’t pass through cracked air ducts on its way to every room. This can save you as much as 30 percent on your heating and cooling bills. Plus, if your house doesn’t already have ducts, you avoid the inconvenience and expense connected to adding them.
    • Choose the ideal temp for all rooms: 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.
    • Use less money and energy by not heating and cooling unused areas: Closing supply registers in a central HVAC system can disturb it, putting stress on the equipment and invalidating any potential savings. But with individual air handlers in each room, you can heat and cool specific areas only when you need them.
