All About Mini-Split Air Conditioners: What They Are and How They Work

August 18, 2017

The majority of homeowners are most familiar with central air conditioners.

Mini-split systems are a kind of ductless heating and cooling. In place of providing conditioned air to the total home with a network of air ducts, they heat and cool a lone 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 like heat pumps in the way they run. Both kinds of equipment provide electric cooling, just like an air conditioner. This involves using refrigerant to remove heat from inside a building and discharging that warm air outside. Then, a reversing valve enables the system to work backward, warming your residence in the winter by extracting heat from outdoor air and bringing it inside.

The biggest difference between mini-splits and heat pumps is that mini-split systems don’t require ductwork. Alternatively, the indoor unit has a built-in air handler, which mounts directly to the wall or ceiling in the space 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 similar to an air conditioner or heat pump condenser.

Multiple indoor units can link to a single outdoor condenser, enabling you to heat and cool your entire residence with this system if desired. This configuration also makes zoning practical, an extremely desirable feature that lets you choose when, where and how much you heat and cool specific spaces.

Is a Ductless Mini-Split Right for My House?

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

  • You can heat and cool an entire residence that lacks existing ductwork.
  • It’s possible to shut off the heat and air conditioning in empty areas to save on your energy expenses.
  • Mini-splits give added heating and cooling for areas that are difficult to keep comfortable.
  • Use a ductless system to heat and cool a home addition or enclosed porch without the cost of adding ductwork or the hassle of using window AC units.
  • Mini-splits are the ideal choice for spaces where traditional ducts is impractical. A few examples might be period homes, tiny homes, temperature controlled sheds or workshops, or garage conversions.
  • What are the Perks of a Mini-Split System?

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

    • Avoid the drawbacks of ductwork: By giving heated and cooled air directly, air doesn’t go through cracked air ducts on its way to all rooms. This can save you upward of 30 percent on your heating and cooling bills. Also, if your residence doesn’t already have ducts, you avoid the hassle and expense that comes with putting them in.
    • Find the ideal setting for each room: With zoned heating and cooling from a ductless mini-split, you can keep an office refreshing while maintaining a warm nursery—all while optimizing energy efficiency.
    • Use less money and energy by not heating and cooling empty spaces: Closing supply registers in a central HVAC system can throw it off balance, putting strain on the equipment and negating any possible savings. But with individual air handlers in each room, you can heat and cool particular rooms only when you need them.
