Ductless A/C vs Central Air
Ductless A/C Systems
A ductless system (also called a mini-split) operates with an outdoor compressor unit connected to a maximum of eight indoor units to distribute air conditioning throughout your home. Mini split systems can cool individual rooms without the use of ducts.
A major advantage of the ductless mini-split system is that the temperature of each room in your home can be controlled separately. This makes the mini split a great option for a family that needs flexible climate control and comfort.
Central Air Systems
Central air conditioners also function with outdoor compressors, but the difference is that they connect to one indoor unit which is usually your furnace in the garage or basement. Then air is sent through various ducts in your home and eventually distributed through vents in each room.
With central air, the temperature is the same in every room and is controlled by one centrally located thermostat.
Advantages of a Mini Split System
There are obvious advantages of a mini-split air conditioning system. It is small and easy to install. There are no ducts necessary, because the outdoor unit powers each indoor unit by using one refrigerant line installed by simply drilling a hole in the wall. The installation is much quicker and less expensive than installing central air.
Mini-split air conditioning is also more efficient because you can control the temperature of individual room, so you are not wasting energy cooling empty rooms in your home. You can also accommodate family members who prefer different levels of room temperature comfort.
Disadvantages of Central A/C
The disadvantages of a central air conditioning system make having a ductless mini-split system a much better choice. Since central air systems require ducts to operate, more installation time is necessary.
The ducts also require maintenance to keep them clear of dust, dirt and debris. They have to be inspected annually for leaks and adequate insulation, otherwise energy can be wasted costing you more money.
