Guide to Mini-Split Air Conditioners: What They Are and How They Work

August 18, 2017

Many homeowners are acquainted with central air conditioners.

Mini-split systems are a kind of ductless heating and cooling. In place of delivering conditioned air to the total residence through a network of air ducts, they heat and cool a lone room at a time. This provides more direct temperature control, increasing comfort and energy efficiency.

How Do Mini-Split Air Conditioners Work?

Mini-splits are most similar to heat pumps in the way they cool. Both styles of equipment offer electric cooling, the same as an air conditioner. This involves using refrigerant to remove heat from within a building and discharging that warmth outside. Then, a reversing valve permits the system to work backward, heating your house in the winter by pulling heat from outdoor air and depositing it inside.

The largest distinction between mini-splits and heat pumps is that mini-split systems don’t have to have ductwork. Instead, the indoor unit has a built-in air handler, which mounts directly to the wall or ceiling in the room you are looking to heat and cool. Copper tubes, wiring and a condensate drain line join to an outdoor condensing unit through a narrow conduit in the wall. This exterior component looks much like an air conditioner or heat pump condenser.

Several indoor units can work off of an individual outdoor condenser, enabling you to heat and cool your total residence with this system if if you want. This configuration also makes zoning feasible, a very desirable feature that lets you choose when, where and how much you heat and cool individual rooms.

Is a Ductless Mini-Split Right for My Residence?

Mini-splits are a fantastic solution for many households. Think over these reasons why using a ductless mini-split might be a good choice for your home:

  • You can heat and cool a total house that has no existing ductwork.
  • You can shut off the heat and air conditioning in unoccupied rooms to save on your energy expenses.
  • Mini-splits deliver extra heating and cooling for areas that are tricky to keep cozy.
  • Use a ductless system to heat and cool a house addition or enclosed patio without the cost of adding ductwork or the annoyance of having window AC units.
  • Mini splits are the perfect choice for spaces where ductwork is impractical. A few examples might be period homes, tiny homes, temperature controlled sheds or workshops, or garage conversions.
  • What are the Advantages of a Mini-Split System?

    Ductless mini-splits are extremely capable systems, but you may still be considering why you would want to choose it over a common furnace and air conditioner. Here’s why more Medina homeowners are using ductless mini-splits:

    • Avoid the pitfalls of ductwork: By delivering heated and cooled air directly, air doesn’t pass through cracked air ducts on its way to every room. This can save you as much as 30 percent on your heating and cooling costs. Along with that, if your home doesn’t already have ducts, you avoid the inconvenience and expense associated with installing them.
    • Select the ideal temp for each room: With zoned heating and cooling from a ductless mini-split, you can keep an office refreshing while maintaining a comfortable nursery—all while optimizing energy efficiency.
    • Use less money and energy by not heating and cooling unused rooms: Closing supply registers in a central HVAC system can disturb it, putting strain on the equipment and canceling any likely savings. But with individual air handlers in every room, you can heat and cool particular areas only when you need them.
