All About 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 kind of ductless heating and cooling. Instead of delivering conditioned air to the full residence through a network of air ducts, they heat and cool a lone room at a time. This allows more advanced temperature control, improving comfort and energy efficiency.

How Do Mini-Split Air Conditioners Work?

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

The largest difference between mini-splits and heat pumps is that mini-split systems don’t require ductwork. As an alternative, the indoor unit has a built-in air handler, which fits directly on the wall or ceiling in the room you want to heat and cool. Copper tubes, wiring and a condensate drain line link to an outdoor condensing unit through a little conduit in the wall. This exterior component looks like an air conditioner or heat pump condenser.

More than one indoor unit can link to a single outdoor condenser, enabling you to heat and cool your total house with this system if if you want. This set-up also makes zoning feasible, a highly attractive feature that permits you to customize when, where and how much you heat and cool individual spaces.

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

Mini-splits are a good choice for the majority of households. Consider these reasons why installing a ductless mini-split may be a wise choise for your needs:

  • You can heat and cool a complete home that doesn’t have existing ductwork.
  • You’ll be able to switch off the heat and air conditioning in empty areas to save on your heating and cooling expenses.
  • Mini-splits provide additional 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 putting in ductwork or the annoyance of having window AC units.
  • Mini-splits are the ideal choice for spaces where ductwork is impractical. A few examples are 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 capable systems, but you could still be wondering why you would want to choose it over a common furnace and air conditioner. Here’s why more Jacksonville homeowners are getting ductless mini-splits:

    • Avoid the hidden issues of ductwork: By giving heated and cooled air directly, air doesn’t move through holey 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 home doesn’t already use ducts, you avoid the annoyance and expense that comes 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 chilly while maintaining a cozy nursery—all while optimizing energy efficiency.
    • Save money and energy by not heating and cooling empty spaces: Shutting supply registers in a central HVAC system can throw it off kilter, putting strain on the equipment and invalidating any potential savings. But with independent air handlers in each room, you can heat and cool certain rooms only when you need them.
