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

August 18, 2017

Most homeowners are informed about central air conditioners.

Mini-split systems are a form of ductless heating and cooling. Rather than providing conditioned air to the full home through a network of air ducts, they heat and cool a single room at a time. This delivers more direct temperature control, increasing comfort and energy efficiency.

How Do Mini-Split Air Conditioners Work?

Mini-splits are most like heat pumps in the way they cool. Both models of equipment deliver electric cooling, just like an air conditioner. This uses refrigerant to extract heat from within a building and exhausting that warm air outside. Then, a reversing valve permits the system to run backward, warming your home in the winter by removing heat from outdoor air and depositing it inside.

The main contrast 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 fits directly on the wall or ceiling in the room you are looking to heat and cool. Copper tubes, wiring and a condensate drain line link to an outdoor condensing unit through a narrow conduit in the wall. This exterior component looks like an air conditioner or heat pump condenser.

More than one indoor unit can link to one outdoor condenser, permitting you to heat and cool your complete house with this system if if you want. This set-up also makes zoning practical, an extremely popular feature that lets you choose when, where and how much you heat and cool specific rooms.

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

Mini-splits are a great choice for many households. Think about these reasons why using a ductless mini-split might be right for your needs:

  • You can heat and cool a total home that lacks existing ductwork.
  • It’s possible to shut off the heat and air conditioning in unused rooms to save on your heating and cooling costs.
  • Mini-splits provide supplementary heating and cooling for spaces that are hard to keep comfy.
  • Use a ductless system to heat and cool a residence addition or enclosed patio without the hassle of installing 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 are historic 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 effective systems, but you may still be wondering why you would want to choose it over a regular furnace and air conditioner. Here’s why more Houston 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 annoyance and expense connected to installing them.
    • Select the right temp for all rooms: With zoned heating and cooling from a ductless mini-split, you can keep an office chilly while maintaining a comfortable nursery—all while optimizing energy efficiency.
    • Save money and energy by not heating and cooling vacant rooms: Shutting supply registers in a central HVAC system can throw it off kilter, putting stress on the equipment and canceling any potential savings. But with independent air handlers in all rooms, you can heat and cool particular areas only when you need them.
