Guide to 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 full residence through a network of air ducts, they heat and cool one room at a time. This allows more targeted temperature control, enhancing 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 provide electric cooling, just like an air conditioner. This requires using refrigerant to remove heat from inside a building and exhausting that warmth outside. Then, a reversing valve permits the system to operate backward, warming your house in the winter by pulling heat from outdoor air and bringing it inside.

The biggest contrast between mini-splits and heat pumps is that mini-split systems don’t need ductwork. As an alternative, 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 link to an outdoor condensing unit through a narrow conduit in the wall. This exterior component looks similar to an air conditioner or heat pump condenser.

Several indoor units can connect to a single outdoor condenser, enabling you to heat and cool your complete home with this system if desired. This arrangement also makes zoning feasible, a very popular feature that permits you to determine when, where and how much you heat and cool specific rooms.

Is a Ductless Mini-Split Right for My Residence?

Mini-splits are a great option for most households. Think over these reasons why getting a ductless mini-split might be a good choice for your home:

  • You can heat and cool a total residence that has no existing ductwork.
  • You can turn off the heat and air conditioning in unused areas to save on your energy costs.
  • Mini-splits give extra heating and cooling for spaces that are hard to keep comfortable.
  • Use a ductless system to heat and cool a residence addition or enclosed patio without the hassle of adding ductwork or the hassle of relying on window AC units.
  • Mini split systems are the ideal choice for spaces where ductwork is impractical. A few examples might be 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 extremely efficient systems, but you may still be considering why you would want to select it over a regular furnace and air conditioner. Here’s why more Rochester homeowners are getting ductless mini-splits:

    • Avoid the pitfalls of ductwork: By delivering heated and cooled air directly, air doesn’t pass 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 residence doesn’t already have ducts, you avoid the hassle and expense connected to installing them.
    • Select the best temp for each room: With zoned heating and cooling from a ductless mini-split, you can keep an office chilly while maintaining a warm nursery—all while maximizing energy efficiency.
    • Conserve money and energy by not heating and cooling vacant rooms: Shutting supply registers in a central HVAC system can disturb it, putting strain on the equipment and canceling any possible savings. But with independent air handlers in every room, you can heat and cool specific rooms only when you need them.
