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

Most homeowners are most familiar with central air conditioners

Mini-split systems are a type of ductless heating and cooling. Instead of giving conditioned air to the full residence via a network of air ducts, they heat and cool a lone room at a time. This delivers more advanced 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 operate. Both kinds of equipment offer electric cooling, just like an air conditioner. This uses refrigerant to draw out heat from inside a building and issuing that warmth outside. Then, a reversing valve permits the system to work backward, adding warmth to your home in the winter by removing heat from outdoor air and adding it inside. 

The biggest difference between mini-splits and heat pumps is that mini-split systems don’t need ductwork. Alternatively, 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 similar to an air conditioner or heat pump condenser. 

Multiple indoor units can connect to a single outdoor condenser, allowing you to heat and cool your entire residence with this system if desired. This configuration also makes zoning possible, a highly popular feature that allows you to customize when, where and how much you heat and cool specific areas.

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

Mini-splits are an excellent solution for many households. Think over these reasons why using a ductless mini-split might be a smart choice for you: 

  • You can heat and cool an entire residence that lacks existing ductwork. 
  • You can shut off the heat and air conditioning in unused areas to save on your energy expenses. 
  • Mini-splits provide additional heating and cooling for rooms that are hard to keep comfy. 
  • Use a ductless system to heat and cool a house addition or enclosed patio without the hassle of putting in ductwork or the annoyance of relying on window AC units. 
  • Mini-splits are the perfect choice for spaces where overhead ductwork is impractical. A few examples might be historic houses, tiny homes, temperature controlled sheds or workshops, or garage conversions. 

What are the Advantages of a Mini-Split System? 

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

  • Avoid the hidden issues of ductwork: By giving heated and cooled air directly, air doesn’t go through leaky air ducts on its way to every room. This can save you nearly 30 percent on your heating and cooling bills. Plus, if your residence doesn’t already include ducts, you avoid the annoyance and cost associated with adding them. 
  • Select the right temperature for each room: 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. 
  • Use less money and energy by not heating and cooling vacant spaces: Closing supply registers in a central HVAC system can throw it off balance, putting strain on the equipment and negating any possible savings. But with independent air handlers in all rooms, you can heat and cool particular spaces only when you need them.
