All About Mini-Split Air Conditioners: What They Are and How They Cool

August 18, 2017

The majority of homeowners are informed about central air conditioners.

Mini-split systems are a form of ductless heating and cooling. Rather than delivering conditioned air to the full home through a network of air ducts, they heat and cool a lone room at a time. This delivers more advanced 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 kinds of equipment offer electric cooling, the same as an air conditioner. This uses refrigerant to remove heat from in a building and issuing that warmth outside. Then, a reversing valve permits the system to work backward, heating your house in the winter by extracting heat from outdoor air and depositing it inside.

The main contrast between mini-splits and heat pumps is that mini-split systems don’t have to have ductwork. Alternatively, the indoor unit has a built-in air handler, which is installed on the wall or ceiling in the room you want to heat and cool. Copper tubes, wiring and a condensate drain line link 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.

More than one indoor unit can link to one outdoor condenser, enabling you to heat and cool your full house with this system if wanted. This arrangement also makes zoning possible, a very desirable feature that allows you to determine when, where and how much you heat and cool individual areas.

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

Mini-splits are a great solution for most households. Consider these reasons why getting a ductless mini-split might be right for your home:

  • You can heat and cool a complete residence that has no existing ductwork.
  • You can turn off the heat and air conditioning in empty rooms to save on your utility bills.
  • Mini-splits provide extra heating and cooling for spaces that are tricky to keep comfy.
  • Use a ductless system to heat and cool a residence addition or enclosed patio without the expense of putting in ductwork or the inconvenience of using window AC units.
  • Mini splits are the perfect choice for spaces where overhead ductwork is impractical. A few examples might be historic homes, tiny homes, temperature controlled sheds or workshops, or garage conversions.
  • What are the Perks of a Mini-Split System?

    Ductless mini-splits are highly efficient systems, but you could still be thinking why you would want to install it over a common furnace and air conditioner. Here’s why more Hillsborough homeowners are installing ductless mini-splits:

    • Avoid the pitfalls of ductwork: By providing 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 include ducts, you avoid the annoyance and cost that comes with adding them.
    • Select the best setting for all rooms: With zoned heating and cooling from a ductless mini-split, you can keep an office chilly while maintaining a warm nursery—all while optimizing energy efficiency.
    • Save money and energy by not heating and cooling empty areas: Closing supply registers in a central HVAC system can throw it off balance, straining the equipment and invalidating any potential savings. But with independent air handlers in every room, you can heat and cool particular areas only when you need them.
