Guide to Mini-Split Air Conditioners: What They Are and How They Cool

August 18, 2017

Most homeowners are informed about central air conditioners.

Mini-split systems are a type of ductless heating and cooling. Instead of delivering conditioned air to the full home with a network of air ducts, they heat and cool a lone room at a time. This provides more direct 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 cool. Both kinds of equipment provide electric cooling, similar to an air conditioner. This uses refrigerant to extract heat from in a building and exhausting that heat outside. Then, a reversing valve permits the system to run backward, warming your residence 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 need ductwork. As an alternative, the indoor unit has a built-in air handler, which mounts directly to the wall or ceiling in the area you wish to heat and cool. Copper tubes, wiring and a condensate drain line join 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 work off of a single outdoor condenser, enabling you to heat and cool your full home with this system if if you want. This set-up also makes zoning feasible, an extremely desirable feature that allows you to determine when, where and how much you heat and cool specific rooms.

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

Mini-splits are a good option for many households. Consider these reasons why using a ductless mini-split may be a wise choise for your home:

  • You can heat and cool an entire residence that lacks existing ductwork.
  • It’s possible to shut off the heat and air conditioning in unused rooms to save on your utility expenses.
  • Mini-splits provide additional heating and cooling for rooms that are hard to keep comfy.
  • Use a ductless system to heat and cool a residence addition or enclosed patio without the hassle of installing ductwork or the annoyance of relying on window AC units.
  • Mini split systems are the natural choice for spaces where traditional ducts is impractical. A few examples might be period houses, tiny homes, temperature controlled sheds or workshops, or garage conversions.
  • What are the Advantages of a Mini-Split System?

    Ductless mini-splits are extremely efficient systems, but you may still be wondering why you would want to select it over a traditional furnace and air conditioner. Here’s why a large number of Tempe homeowners are installing ductless mini-splits:

    • Avoid the hidden issues of ductwork: By providing heated and cooled air directly, air doesn’t pass through leaky air ducts on its way to each room. This can save you upward of 30 percent on your heating and cooling costs. Plus, if your residence doesn’t already include ducts, you avoid the annoyance and expense that comes with installing them.
    • Select the right temperature for every room: With zoned heating and cooling from a ductless mini-split, you can keep an office chilly while maintaining a comfortable nursery—all while maximizing energy efficiency.
    • Conserve money and energy by not heating and cooling empty spaces: Shutting supply registers in a central HVAC system can throw it off kilter, straining the equipment and negating any likely savings. But with individual air handlers in each room, you can heat and cool particular spaces only when you need them.
