All About 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 type of ductless heating and cooling. In place of delivering conditioned air to the entire residence via a network of air ducts, they heat and cool a single room at a time. This allows more targeted temperature control, enhancing 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 offer electric cooling, the same as an air conditioner. This involves using refrigerant to remove heat from within a building and exhausting that warm air outside. Then, a reversing valve enables the system to run backward, heating your home in the winter by removing heat from outdoor air and depositing it inside.

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

Multiple indoor units can work off of an individual outdoor condenser, enabling you to heat and cool your entire house with this system if wanted. This set-up also makes zoning feasible, a very coveted feature that permits you to choose when, where and how much you heat and cool individual spaces.

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

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

  • You can heat and cool a total house that lacks existing ductwork.
  • You can shut off the heat and air conditioning in empty spaces to save on your utility bills.
  • Mini-splits provide additional heating and cooling for spaces that are difficult to keep comfortable.
  • Use a ductless system to heat and cool a residence addition or enclosed porch without the expense of adding ductwork or the annoyance of using window AC units.
  • Mini split systems are the ideal choice for spaces where ductwork is impractical. A few examples might be period 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 efficient systems, but you could still be considering why you would want to select it over a regular furnace and air conditioner. Here’s why more Orlando homeowners are getting ductless mini-splits:

    • Avoid the hidden issues of ductwork: By providing heated and cooled air directly, air doesn’t pass through cracked air ducts on its way to every room. This can save you upward of 30 percent on your heating and cooling bills. Plus, if your house doesn’t already use ducts, you avoid the annoyance and cost connected to adding them.
    • Find the best temp for every room: 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.
    • Save money and energy by not heating and cooling empty rooms: Closing supply registers in a central HVAC system can throw it off balance, putting stress on the equipment and invalidating any possible savings. But with individual air handlers in each room, you can heat and cool certain spaces only when you need them.
