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

August 18, 2017

Many homeowners are most familiar with central air conditioners.

Mini-split systems are a form of ductless heating and cooling. Rather than giving conditioned air to the entire house through a network of air ducts, they heat and cool one room at a time. This provides more advanced 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 kinds of equipment deliver electric cooling, similar to an air conditioner. This involves using refrigerant to remove heat from within a building and discharging that heat outside. Then, a reversing valve permits the system to work backward, adding warmth to your residence in the winter by pulling heat from outdoor air and adding it inside.

The largest 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 area you want 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 like an air conditioner or heat pump condenser.

Several indoor units can link to a single outdoor condenser, enabling you to heat and cool your full residence with this system if if you want. This set-up also makes zoning feasible, a very popular feature that permits you to choose when, where and how much you heat and cool distinct rooms.

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

Mini-splits are a fantastic solution for many households. Consider these reasons why installing 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 switch off the heat and air conditioning in unused areas to save on your energy bills.
  • Mini-splits give added heating and cooling for spaces that are hard to keep comfortable.
  • Use a ductless system to heat and cool a house addition or enclosed porch without the hassle of installing ductwork or the inconvenience of having window AC units.
  • Mini splits are the ideal choice for spaces where overhead ductwork is impractical. A few examples might be historic 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 capable systems, but you may still be wondering why you would want to install it over a common furnace and air conditioner. Here’s why a growing number of Naples homeowners are getting ductless mini-splits:

    • Avoid the pitfalls of ductwork: By giving heated and cooled air directly, air doesn’t go through leaky air ducts on its way to every room. This can save you nearly 30 percent on your heating and cooling costs. Also, if your residence doesn’t already have ducts, you avoid the annoyance and cost that comes with installing them.
    • Choose the best temperature for each room: With zoned heating and cooling from a ductless mini-split, you can keep an office refreshing while maintaining a comfortable nursery—all while optimizing energy efficiency.
    • Conserve money and energy by not heating and cooling empty areas: Closing supply registers in a central HVAC system can disturb it, putting stress on the equipment and negating any likely savings. But with independent air handlers in each room, you can heat and cool certain spaces only when you need them.
