Ductless AC units are a relatively new option for residential homes. Ductless systems are highly efficient for maintaining optimal indoor air quality because no duct system is utilized to deliver conditioned air throughout the home. Ductwork tends to collect contaminants, dust and polluting particles as time goes on. Regular ductwork cleaning is important for ducted systems so that the quality of air inside the home remains pure. With ductless systems, no ductwork cleaning or repair is required because there is no duct system to clean or repair!
Ductless AC units are also known as mini-split units. Ductless systems are designed in such a way that the outdoor compressor does part of the work to cool the home. However, during AC installation, a unit is placed in each room. Each room unit contains an evaporator and a blower fan. The conditioned air is created and dispersed from the in-room units.
A ductless AC installation is cleaner than a ducted system. However, they also are more energy efficient, as well. The homeowner may control the temperature of each room. Unlike a ducted system, which requires the system to produce cooled air to many rooms at once, the homeowner may control each in-room unit independently. The ability to control the temperature in each room means that less energy is used to keep the inhabitants cool and less cool air is wasted.
Aside from the ability to control the temperature in each room, ductless systems generally are rated as more efficient in energy usage. This rating is known as SEER. Ductless systems have higher SEER ratings, which means that these systems use electricity more efficiently to meet the demands of cooling the home.
Though a ductless AC installation may require more of an initial investment, these systems will save on electricity costs over time. In addition, these newer, more efficient systems will increase the resale value of the home.
