A ductless mini-split system is comprised of an indoor unit called the evaporator and an outdoor unit called the condensing unit. The evaporator is connected to the condensing unit by copper tubing and electrical wiring which is passed through a 2 ½” – 3” hole. Basically, it is a small central air unit with the flexibility of cooling or heating one room or more; zoning.
What are the advantages of installing a Fujitsu ductless mini-split over a central air system?
1) With Central Air you must cool an entire home when only one room may need cooling. On the other hand, ductless mini-splits cool only the areas you want and not the areas you don’t.
2) 18,000 BTU is a typical minimum central air unit. With ductless mini-splits, you can use 7,000, 9,000 or 12,000 BTUs.
3) Typical 3-ton homes are not zoned or require complex zoning systems, which makes it very expensive for the homeowner. With ductless mini-splits, multiple evaporators make zoning as simple as setting a remote control.
4) Energy wasted in long lengths of uninhabited ductwork means higher energy bills. Less than 5% cooling loss occurs in insulated refrigerant lines compared with up to 25% through ducts.
5) Retrofitting homes requires cutting holes in walls, floors, ceilings or decreasing closet space with ducts. Ductless mini-splits requires just a 3 or 4” diameter hole in the outside wall. Means less mess and better home aesthetics.
