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

August 18, 2017

Many homeowners are most familiar with central air conditioners.

Mini-split systems are a form of ductless heating and cooling. Rather than providing conditioned air to the total residence through a network of air ducts, they heat and cool a single room at a time. This provides more direct 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 operate. 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 issuing that warm air outside. Then, a reversing valve permits the system to operate backward, heating your home in the winter by extracting heat from outdoor air and bringing it inside.

The largest contrast between mini-splits and heat pumps is that mini-split systems don’t need ductwork. Alternatively, 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 connect to an outdoor condensing unit through a narrow conduit in the wall. This exterior component looks like an air conditioner or heat pump condenser.

Several indoor units can link to an individual outdoor condenser, allowing you to heat and cool your total home with this system if wanted. This configuration also makes zoning practical, a highly desirable feature that allows you to customize when, where and how much you heat and cool individual spaces.

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

Mini-splits are a fantastic choice for many households. Think about these reasons why getting a ductless mini-split may be a smart choice for you:

  • You can heat and cool a total home that doesn’t have existing ductwork.
  • You can switch off the heat and air conditioning in empty spaces to save on your utility bills.
  • Mini-splits give extra heating and cooling for areas that are difficult to keep comfy.
  • Use a ductless system to heat and cool a house addition or sunroom without the hassle of installing ductwork or the annoyance of having window AC units.
  • Mini splits are the perfect choice for spaces where ductwork is impractical. A few examples might be period homes, tiny homes, temperature controlled sheds or workshops, or garage conversions.
  • What are the Benefits of a Mini-Split System?

    Ductless mini-splits are extremely effective systems, but you could still be considering why you would want to choose it over a regular furnace and air conditioner. Here’s why more Concord 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 costs. Also, if your house doesn’t already use ducts, you avoid the hassle and cost associated with putting them in.
    • Choose the right temperature for each room: With zoned heating and cooling from a ductless mini-split, you can keep an office refreshing while maintaining a warm nursery—all while making the most of energy efficiency.
    • Conserve money and energy by not heating and cooling empty areas: Shutting supply registers in a central HVAC system can disturb it, putting stress on the equipment and negating any likely savings. But with independent air handlers in every room, you can heat and cool certain rooms only when you need them.
