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

August 18, 2017

Many homeowners are informed about central air conditioners.

Mini-split systems are a form of ductless heating and cooling. Rather than delivering conditioned air to the full residence with a network of air ducts, they heat and cool a single room at a time. This delivers more targeted temperature control, improving comfort and energy efficiency.

How Do Mini-Split Air Conditioners Work?

Mini-splits are most similar to heat pumps in the way they operate. Both kinds of equipment offer electric cooling, similar to an air conditioner. This involves using refrigerant to draw out heat from in a building and exhausting that warmth outside. Then, a reversing valve permits the system to operate backward, adding warmth to your residence in the winter by extracting heat from outdoor air and bringing it inside.

The main contrast 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 space you want to heat and cool. Copper tubes, wiring and a condensate drain line connect to an outdoor condensing unit through a small conduit in the wall. This exterior component looks like an air conditioner or heat pump condenser.

Multiple indoor units can connect to a single outdoor condenser, enabling you to heat and cool your complete home with this system if wanted. This set-up also makes zoning practical, a highly attractive feature that allows you to customize when, where and how much you heat and cool individual spaces.

Is a Ductless Mini-Split Right for My House?

Mini-splits are a great solution for the majority of households. Think over these reasons why getting a ductless mini-split could be right for you:

  • You can heat and cool a total residence that has no existing ductwork.
  • You can switch off the heat and air conditioning in unoccupied areas to save on your utility expenses.
  • Mini-splits give extra heating and cooling for spaces that are hard to keep cozy.
  • Use a ductless system to heat and cool a residence addition or enclosed porch without the cost of installing ductwork or the inconvenience of having window AC units.
  • Mini splits are the perfect choice for spaces where ductwork is impractical. A few examples are historic homes, tiny homes, temperature controlled sheds or workshops, or garage conversions.
  • What are the Benefits of a Mini-Split System?

    Ductless mini-splits are extremely efficient systems, but you may still be thinking why you would want to select it over a regular furnace and air conditioner. Here’s why more Fort Lauderdale homeowners are installing ductless mini-splits:

    • Avoid the pitfalls of ductwork: By providing heated and cooled air directly, air doesn’t go through holey air ducts on its way to all rooms. This can save you nearly 30 percent on your heating and cooling bills. Also, if your house doesn’t already include ducts, you avoid the hassle and cost 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 refreshing while maintaining a cozy nursery—all while making the most of energy efficiency.
    • Use less money and energy by not heating and cooling unused rooms: Shutting supply registers in a central HVAC system can throw it off balance, straining the equipment and canceling any likely savings. But with independent air handlers in every room, you can heat and cool specific rooms only when you need them.
