All About 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. In place of delivering conditioned air to the full house through a network of air ducts, they heat and cool a lone room at a time. This allows more targeted temperature control, enhancing comfort and energy efficiency.

How Do Mini-Split Air Conditioners Work?

Mini-splits most closely resemble heat pumps in the way they run. Both models of equipment offer electric cooling, just like an air conditioner. This requires using refrigerant to remove heat from within a building and exhausting that warmth outside. Then, a reversing valve allows the system to run backward, warming your residence in the winter by extracting heat from outdoor air and bringing it inside.

The largest distinction between mini-splits and heat pumps is that mini-split systems don’t require ductwork. Instead, the indoor unit has a built-in air handler, which is installed on the wall or ceiling in the area you wish 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 much like an air conditioner or heat pump condenser.

More than one indoor unit can connect to an individual outdoor condenser, enabling you to heat and cool your total residence with this system if wanted. This set-up also makes zoning feasible, a very popular feature that permits you to choose when, where and how much you heat and cool individual areas.

Is a Ductless Mini-Split Right for My Home?

Mini-splits are an excellent choice for the majority of households. Consider these reasons why getting a ductless mini-split may be right for you:

  • You can heat and cool a total residence that has no existing ductwork.
  • It’s possible to switch off the heat and air conditioning in unused rooms to save on your heating and cooling bills.
  • Mini-splits deliver additional heating and cooling for areas that are difficult to keep comfortable.
  • Use a ductless system to heat and cool a residence addition or enclosed patio without the hassle of installing ductwork or the annoyance of using window AC units.
  • Mini splits are the natural choice for spaces where overhead ductwork is impractical. A few examples are historic 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 capable systems, but you might still be wondering why you would want to install it over a traditional furnace and air conditioner. Here’s why more Pierre homeowners are getting ductless mini-splits:

    • Avoid the drawbacks of ductwork: By providing heated and cooled air directly, air doesn’t pass through holey air ducts on its way to all rooms. This can save you as much as 30 percent on your heating and cooling expenses. Plus, if your home doesn’t already use ducts, you avoid the inconvenience and cost connected to putting them in.
    • Select the ideal temp for all rooms: With zoned heating and cooling from a ductless mini-split, you can keep an office chilly while maintaining a warm nursery—all while maximizing energy efficiency.
    • Conserve money and energy by not heating and cooling vacant spaces: Shutting supply registers in a central HVAC system can disturb it, straining the equipment and negating any likely savings. But with individual air handlers in each room, you can heat and cool particular rooms only when you need them.
