Four pros and cons of a mini-split air-conditioning unit
You may be asking yourself, what is a mini-split air-conditioning unit?
That’s not too surprising, but they are definitely something you need to know about here in the desert.
Mini-splits are small, ductless, split-system air conditioners that are becoming more and more popular.
They’re a great solution for small apartments, garages and those bedrooms that you can never seem to cool down, even though you have central air conditioning.
Just like larger central air-conditioning systems that are called split-systems, they have an outdoor compressor or condenser plus an indoor handling unit with tubes running between the pieces of equipment.
- They’re small and flexible.
- They are easy to install and need only a three-inch hole punched through a wall for the conduit that carries the tubes.
- They require no ducts so they avoid energy loss associated with leaky ducts that are often problems in central AC systems.
- They can hang from a ceiling, be mounted on a wall or can be floor-standing units. For a one-room unit, the indoor air handler can be about a yard wide by a foot tall and 7-10 inches deep. The condenser outdoors is about a yard wide by a yard tall and a foot in depth.
- They can be expensive. These systems can cost twice as much as similar window A/C units, according to the U.S. Department of Energy.
- Although the air handler units are small, they’re more noticeable than an indoor vent for a central air conditioning system might be.
- Units must be carefully installed by contractors who know how to work with them.
- Although you might be able to use one outdoor unit to run a couple of indoor air handlers in separate rooms, they generally would not be able to cool an entire house.
