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

August 18, 2017

Many homeowners are acquainted with central air conditioners.

Mini-split systems are a kind of ductless heating and cooling. Instead of providing conditioned air to the full residence through a network of air ducts, they heat and cool a single room at a time. This delivers more direct temperature control, improving comfort and energy efficiency.

How Do Mini-Split Air Conditioners Work?

Mini-splits are most like heat pumps in the way they run. Both types of equipment deliver electric cooling, similar to an air conditioner. This involves using refrigerant to remove heat from inside a building and discharging that heat outside. Then, a reversing valve allows the system to run backward, heating your residence in the winter by extracting heat from outdoor air and adding it inside.

The biggest distinction 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 is installed 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 small conduit in the wall. This exterior component looks like an air conditioner or heat pump condenser.

Several indoor units can work off of one outdoor condenser, allowing you to heat and cool your entire residence with this system if desired. This arrangement also makes zoning feasible, a very coveted feature that lets you determine when, where and how much you heat and cool distinct spaces.

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

Mini-splits are an excellent option for many households. Consider these reasons why using a ductless mini-split may be right for you:

  • You can heat and cool a complete residence that has no existing ductwork.
  • You’ll be able to shut off the heat and air conditioning in unused areas to save on your utility costs.
  • Mini-splits give added heating and cooling for areas that are hard to keep cozy.
  • Use a ductless system to heat and cool a residence addition or sunroom without the cost of installing ductwork or the inconvenience of relying on window AC units.
  • Mini-splits are the ideal choice for spaces where ductwork is impractical. A few examples might be historic houses, tiny homes, temperature controlled sheds or workshops, or garage conversions.
  • What are the Advantages of a Mini-Split System?

    Ductless mini-splits are highly effective systems, but you may still be wondering why you would want to select it over a common furnace and air conditioner. Here’s why a large number of Oakville homeowners are getting ductless mini-splits:

    • Avoid the pitfalls of ductwork: By delivering heated and cooled air directly, air doesn’t go through holey air ducts on its way to every room. This can save you upward of 30 percent on your heating and cooling bills. Along with that, if your home doesn’t already have ducts, you avoid the inconvenience and cost associated with adding them.
    • Find the ideal temperature for each room: With zoned heating and cooling from a ductless mini-split, you can keep an office cool while maintaining a comfortable nursery—all while making the most of energy efficiency.
    • Conserve money and energy by not heating and cooling vacant rooms: Securing supply registers in a central HVAC system can throw it off kilter, putting strain on the equipment and canceling any potential savings. But with detached air handlers in each room, you can heat and cool certain rooms only when you need them.
