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

Most homeowners are acquainted with central air conditioners

Mini-split systems are a kind of ductless heating and cooling. In place of providing conditioned air to the entire residence via a network of air ducts, they heat and cool a lone room at a time. This allows more direct 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 run. Both models of equipment provide electric cooling, similar to an air conditioner. This involves using refrigerant to remove heat from in a building and exhausting that warmth outside. Then, a reversing valve enables the system to operate backward, warming your home in the winter by extracting heat from outdoor air and depositing it inside. 

The largest distinction 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 fits directly on the wall or ceiling in the room you want to heat and cool. Copper tubes, wiring and a condensate drain line connect to an outdoor condensing unit through a little conduit in the wall. This exterior component looks similar to an air conditioner or heat pump condenser. 

Several indoor units can connect to one outdoor condenser, permitting you to heat and cool your total home with this system if wanted. This arrangement also makes zoning possible, a very attractive feature that allows you to choose when, where and how much you heat and cool specific areas.

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

Mini-splits are a great solution for most households. Think about these reasons why getting a ductless mini-split could be a wise choice for your needs: 

  • You can heat and cool a total house that lacks existing ductwork. 
  • It’s possible to shut off the heat and air conditioning in unused spaces to save on your utility costs. 
  • Mini-splits provide additional heating and cooling for rooms that are difficult to keep comfortable. 
  • Use a ductless system to heat and cool a house addition or enclosed porch without the expense of adding ductwork or the inconvenience of using window AC units. 
  • Mini split systems are the perfect choice for spaces where traditional ducts is impractical. A few examples are period 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 effective systems, but you could still be wondering why you would want to install it over a traditional furnace and air conditioner. Here’s why a large number of Columbus homeowners are using ductless mini-splits: 

  • Avoid the pitfalls of ductwork: By giving 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 bills. Also, if your house doesn’t already include ducts, you avoid the hassle and cost that comes with installing them. 
  • Choose the best temperature for each room: With zoned heating and cooling from a ductless mini-split, you can keep an office cool while maintaining a warm nursery—all while optimizing energy efficiency. 
  • Conserve money and energy by not heating and cooling empty spaces: Closing supply registers in a central HVAC system can throw it off kilter, straining the equipment and canceling any possible savings. But with individual air handlers in each room, you can heat and cool certain rooms only when you need them.
