Guide to 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 kind of ductless heating and cooling. In place of delivering conditioned air to the complete home via a network of air ducts, they heat and cool one room at a time. This provides more advanced temperature control, increasing 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 kinds of equipment provide electric cooling, just like an air conditioner. This uses refrigerant to extract heat from within a building and issuing that warm air outside. Then, a reversing valve enables the system to work backward, adding warmth to your house in the winter by pulling heat from outdoor air and bringing it inside.

The biggest contrast between mini-splits and heat pumps is that mini-split systems don’t have to have ductwork. Alternatively, the indoor unit has a built-in air handler, which is installed on the wall or ceiling in the room you want to heat and cool. Copper tubes, wiring and a condensate drain line connect to an outdoor condensing unit through a little conduit in the wall. This exterior component looks similar to an air conditioner or heat pump condenser.

Multiple indoor units can connect to an individual outdoor condenser, enabling you to heat and cool your total residence with this system if desired. This configuration also makes zoning feasible, an extremely popular feature that lets you determine when, where and how much you heat and cool distinct rooms.

Is a Ductless Mini-Split Right for My Home?

Mini-splits are a fantastic choice for the majority of households. Think about these reasons why installing a ductless mini-split may be a smart choice for your needs:

  • You can heat and cool an entire residence that doesn’t have existing ductwork.
  • You’ll be able to switch off the heat and air conditioning in empty spaces to save on your heating and cooling costs.
  • Mini-splits provide supplementary heating and cooling for spaces that are difficult to keep cozy.
  • Use a ductless system to heat and cool a residence addition or enclosed porch without the hassle of adding ductwork or the hassle of having window AC units.
  • Mini-splits are the perfect choice for spaces where overhead ductwork 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 may still be wondering why you would want to install it over a traditional furnace and air conditioner. Here’s why more Wheeling homeowners are installing ductless mini-splits:

    • Avoid the drawbacks of ductwork: By giving heated and cooled air directly, air doesn’t move through cracked air ducts on its way to all rooms. This can save you nearly 30 percent on your heating and cooling expenses. Along with that, if your house doesn’t already include ducts, you avoid the annoyance and expense that comes with adding them.
    • Select the best temp for each room: With zoned heating and cooling from a ductless mini-split, you can keep an office refreshing while maintaining a comfortable nursery—all while maximizing energy efficiency.
    • Use less money and energy by not heating and cooling unused areas: Closing supply registers in a central HVAC system can throw it off balance, putting stress on the equipment and canceling any possible savings. But with individual air handlers in each room, you can heat and cool certain spaces only when you need them.
