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

August 18, 2017

Most homeowners are most familiar with central air conditioners.

Mini-split systems are a form of ductless heating and cooling. Instead of delivering conditioned air to the complete residence via a network of air ducts, they heat and cool one room at a time. This allows more direct 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 cool. Both models of equipment provide electric cooling, just like an air conditioner. This requires using refrigerant to draw out heat from in a building and issuing that heat outside. Then, a reversing valve allows the system to work backward, heating your residence in the winter by removing heat from outdoor air and depositing it inside.

The main distinction between mini-splits and heat pumps is that mini-split systems don’t require ductwork. As an alternative, the indoor unit has a built-in air handler, which mounts directly to the wall or ceiling in the room you want to heat and cool. Copper tubes, wiring and a condensate drain line join to an outdoor condensing unit through a small conduit in the wall. This exterior component looks similar to an air conditioner or heat pump condenser.

More than one indoor unit can link to an individual outdoor condenser, permitting you to heat and cool your full home with this system if desired. This configuration also makes zoning practical, a highly desirable feature that lets you determine when, where and how much you heat and cool distinct areas.

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

Mini-splits are a good solution for many households. Think over these reasons why using a ductless mini-split may be a wise choise for your needs:

  • You can heat and cool a total home that doesn’t have existing ductwork.
  • It’s possible to switch off the heat and air conditioning in empty spaces to save on your utility expenses.
  • Mini-splits provide additional heating and cooling for spaces that are hard to keep cozy.
  • Use a ductless system to heat and cool a house addition or enclosed patio without the expense of putting in ductwork or the hassle of relying on window AC units.
  • Mini splits are the natural 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 Perks of a Mini-Split System?

    Ductless mini-splits are extremely capable systems, but you might still be considering why you would want to select it over a traditional furnace and air conditioner. Here’s why more Clearwater homeowners are getting ductless mini-splits:

    • Avoid the drawbacks of ductwork: By providing heated and cooled air directly, air doesn’t pass through leaky air ducts on its way to all rooms. This can save you nearly 30 percent on your heating and cooling expenses. Along with that, if your residence doesn’t already use ducts, you avoid the annoyance and cost associated with putting them in.
    • Choose the ideal temperature for every room: With zoned heating and cooling from a ductless mini-split, you can keep an office refreshing while maintaining a comfortable nursery—all while maximizing energy efficiency.
    • Use less money and energy by not heating and cooling unused spaces: Shutting supply registers in a central HVAC system can throw it off kilter, putting strain on the equipment and negating any potential savings. But with detached air handlers in every room, you can heat and cool particular rooms only when you need them.
