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

August 18, 2017

Many homeowners are most familiar with central air conditioners.

Mini-split systems are a form of ductless heating and cooling. Instead of providing conditioned air to the total home through a network of air ducts, they heat and cool a lone room at a time. This provides 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 run. Both kinds of equipment deliver electric cooling, just like an air conditioner. This requires using refrigerant to remove heat from within a building and exhausting that warm air outside. Then, a reversing valve enables the system to operate backward, heating your house in the winter by pulling heat from outdoor air and depositing it inside.

The largest difference 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 area you want 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 work off of one outdoor condenser, enabling you to heat and cool your complete house with this system if desired. This configuration also makes zoning possible, a highly coveted feature that lets you determine when, where and how much you heat and cool distinct rooms.

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

Mini-splits are an excellent option for the majority of households. Think over these reasons why installing a ductless mini-split could be right for you:

  • You can heat and cool a complete home that has no existing ductwork.
  • You can switch off the heat and air conditioning in unoccupied areas to save on your energy bills.
  • Mini-splits deliver additional heating and cooling for spaces that are difficult to keep comfy.
  • Use a ductless system to heat and cool a residence addition or enclosed porch without the hassle of putting in ductwork or the hassle of using window AC units.
  • Mini-splits are the perfect choice for spaces where overhead ductwork 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 extremely efficient systems, but you may still be thinking why you would want to select it over a traditional furnace and air conditioner. Here’s why a growing number of Winnipeg homeowners are installing 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 all rooms. This can save you upward of 30 percent on your heating and cooling bills. Also, if your home doesn’t already have ducts, you avoid the annoyance and price that comes with putting them in.
    • Select the ideal temp for all rooms: With zoned heating and cooling from a ductless mini-split, you can keep an office refreshing while maintaining a cozy nursery—all while optimizing energy efficiency.
    • Conserve money and energy by not heating and cooling empty rooms: Closing supply registers in a central HVAC system can throw it off kilter, straining the equipment and canceling any possible savings. But with independent air handlers in each room, you can heat and cool certain rooms only when you need them.
