Some of the ways that mini split air conditioners differ from other cooling systems include they don't require duct work, are ideal for small rooms, are easy to install and offer greater flexibility in terms of options for interior design. One of the major disadvantages is the initial cost.
Mini split air conditioners are mainly used in multifamily homes, small apartments, room additions and places that lack duct work. Like central air systems, mini split air conditioners operate off of an outdoor condenser and an interior air-handling unit. The conduit contains suction tubing, a condensate drain, refrigeration tubing and a power cable.
Some mini split air conditioners can cool four rooms simultaneously. Each zone has an individual thermostat, which can save on overall cost and energy use. Another difference is that a mini split air conditioner's outdoor unit can be placed as far away as 50 feet from the interior evaporator. One of the biggest advantages of mini split air conditioners is that they don't lose as much energy through the ducts when compared to central forced-air systems.
To save as much energy as possible with a mini split air conditioner, an individual must ensure the air handlers are the right size. It is also best to have the unit installed by a technician who specializes in mini splits.
