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

August 18, 2017

Most homeowners are acquainted with central air conditioners.

Mini-split systems are a type of ductless heating and cooling. Instead of giving conditioned air to the complete house via a network of air ducts, they heat and cool one room at a time. This allows more advanced temperature control, improving comfort and energy efficiency.

How Do Mini-Split Air Conditioners Work?

Mini-splits most closely resemble heat pumps in the way they cool. Both kinds of equipment deliver electric cooling, the same as an air conditioner. This uses refrigerant to extract heat from in a building and exhausting that warmth outside. Then, a reversing valve allows the system to work backward, adding warmth to your home in the winter by pulling heat from outdoor air and depositing it inside.

The biggest difference between mini-splits and heat pumps is that mini-split systems don’t need ductwork. Instead, the indoor unit has a built-in air handler, which is installed on the wall or ceiling in the space you are looking to heat and cool. Copper tubes, wiring and a condensate drain line connect 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, allowing you to heat and cool your full house with this system if if you want. This configuration also makes zoning feasible, a very popular feature that allows you to customize when, where and how much you heat and cool distinct areas.

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

Mini-splits are an excellent option for most households. Think over these reasons why using a ductless mini-split might be a smart choice for your home:

  • You can heat and cool a complete home that doesn’t have existing ductwork.
  • You’ll be able to shut off the heat and air conditioning in empty areas to save on your utility bills.
  • Mini-splits deliver supplementary heating and cooling for areas that are hard to keep comfortable.
  • Use a ductless system to heat and cool a house addition or sunroom without the cost of putting in ductwork or the hassle of having window AC units.
  • Mini splits are the natural choice for spaces where traditional ducts is impractical. A few examples are period homes, tiny homes, temperature controlled sheds or workshops, or garage conversions.
  • What are the Benefits of a Mini-Split System?

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

    • Avoid the hidden issues of ductwork: By giving heated and cooled air directly, air doesn’t move through leaky air ducts on its way to each room. This can save you nearly 30 percent on your heating and cooling costs. Along with that, if your house doesn’t already use ducts, you avoid the inconvenience and expense that comes with putting them in.
    • Choose the best temp for every room: With zoned heating and cooling from a ductless mini-split, you can keep an office refreshing while maintaining a cozy nursery—all while making the most of energy efficiency.
    • Use less money and energy by not heating and cooling empty rooms: Shutting supply registers in a central HVAC system can disturb it, putting strain on the equipment and invalidating any possible savings. But with individual air handlers in all rooms, you can heat and cool specific areas only when you need them.
