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 form of ductless heating and cooling. Instead of delivering conditioned air to the complete home via a network of air ducts, they heat and cool one room at a time. This allows more targeted 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 operate. Both models of equipment offer electric cooling, similar to an air conditioner. This involves using refrigerant to draw out heat from inside a building and discharging that heat outside. Then, a reversing valve enables the system to work backward, heating your residence in the winter by extracting heat from outdoor air and adding it inside.

The main distinction 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 room you want to heat and cool. Copper tubes, wiring and a condensate drain line join to an outdoor condensing unit through a little conduit in the wall. This exterior component looks much like an air conditioner or heat pump condenser.

Multiple indoor units can link to an individual outdoor condenser, permitting you to heat and cool your total house with this system if desired. This configuration also makes zoning possible, a very attractive feature that permits you to choose when, where and how much you heat and cool individual areas.

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

Mini-splits are a great solution for most households. Think about these reasons why installing a ductless mini-split might be a smart choice for your home:

  • You can heat and cool a complete house that doesn’t have existing ductwork.
  • You’ll be able to switch off the heat and air conditioning in unused areas to save on your utility expenses.
  • Mini-splits deliver added heating and cooling for rooms that are difficult to keep cozy.
  • Use a ductless system to heat and cool a residence addition or enclosed patio without the expense of adding ductwork or the hassle of having window AC units.
  • Mini-splits are the perfect 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 Perks of a Mini-Split System?

    Ductless mini-splits are highly efficient systems, but you may still be considering why you would want to install it over a common furnace and air conditioner. Here’s why a large number of Belleville homeowners are using ductless mini-splits:

    • Avoid the drawbacks of ductwork: By delivering heated and cooled air directly, air doesn’t go through leaky air ducts on its way to every room. This can save you as much as 30 percent on your heating and cooling costs. Also, if your home doesn’t already include ducts, you avoid the inconvenience and cost associated with installing them.
    • Find the right setting for all rooms: With zoned heating and cooling from a ductless mini-split, you can keep an office chilly while maintaining a cozy nursery—all while maximizing energy efficiency.
    • Conserve money and energy by not heating and cooling vacant spaces: Closing supply registers in a central HVAC system can throw it off kilter, putting stress on the equipment and invalidating any potential savings. But with detached air handlers in each room, you can heat and cool particular rooms only when you need them.
