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

August 18, 2017

Most homeowners are most familiar with central air conditioners.

Mini-split systems are a type of ductless heating and cooling. Rather than providing conditioned air to the entire home via a network of air ducts, they heat and cool one room at a time. This allows more targeted temperature control, increasing comfort and energy efficiency.

How Do Mini-Split Air Conditioners Work?

Mini-splits most closely resemble heat pumps in the way they cool. Both models of equipment offer electric cooling, just like an air conditioner. This requires using refrigerant to remove heat from in a building and discharging that warm air outside. Then, a reversing valve enables the system to run backward, warming your house in the winter by pulling heat from outdoor air and depositing it inside.

The main difference 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 mounts directly to the wall or ceiling in the space you are looking to heat and cool. Copper tubes, wiring and a condensate drain line link 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.

Several indoor units can link to an individual outdoor condenser, enabling you to heat and cool your complete residence with this system if desired. This set-up also makes zoning practical, a highly attractive feature that lets you choose when, where and how much you heat and cool specific rooms.

Is a Ductless Mini-Split the Best Choice for My Residence?

Mini-splits are an excellent choice for most households. Think about these reasons why using a ductless mini-split could be right for your needs:

  • You can heat and cool a total house that doesn’t have existing ductwork.
  • You can turn off the heat and air conditioning in unused areas to save on your utility bills.
  • Mini-splits deliver extra heating and cooling for areas that are difficult to keep comfy.
  • Use a ductless system to heat and cool a residence addition or enclosed porch without the expense of installing ductwork or the hassle of using window AC units.
  • Mini split systems are the perfect choice for spaces where ductwork is impractical. A few examples are period houses, tiny homes, temperature controlled sheds or workshops, or garage conversions.
  • What are the Perks of a Mini-Split System?

    Ductless mini-splits are very effective systems, but you may still be considering why you would want to select it over a common furnace and air conditioner. Here’s why a large number of Houston homeowners are getting ductless mini-splits:

    • Avoid the pitfalls of ductwork: By giving heated and cooled air directly, air doesn’t go through holey air ducts on its way to every room. This can save you as much as 30 percent on your heating and cooling bills. Plus, if your residence doesn’t already include ducts, you avoid the hassle and price connected to putting them in.
    • Choose the right temperature for all rooms: 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.
    • Conserve money and energy by not heating and cooling unused spaces: Securing supply registers in a central HVAC system can throw it off kilter, putting strain on the equipment and invalidating any potential savings. But with independent air handlers in every room, you can heat and cool specific rooms only when you need them.
