A ductless ac unit (also called a mini split system) is a product that delivers cool air to a single room, or several rooms, where ductwork isn’t possible or wanted. Ductless AC units are a great option for new additions, sunrooms, garages or areas of the home that need to be cooler.
A ductless air conditioner works just like a conventional split central air conditioner in that it has an indoor unit and an outdoor unit (hence the name mini split system). Unlike a bulky and ugly window air conditioner, a ductless air conditioner is mounted to a wall, ceiling or placed in the floor – and a small hole is cut that leads to the outdoor unit where warm air is expelled. After that, the ductless mini split system works just like a traditional air conditioner – just without the expensive and obtrusive ductwork.
Ductless systems can be configured in several ways. There are ductless air conditioners, ductless heat pumps that can both cool and heat a room, as well as ductless zoning systems that allow you to tie several rooms together.
A ductless air conditioner needs similar care and maintenance as a traditional AC unit. For maintenance advice and troubleshooting tips, check out our ductless systems maintenance guide.
Ductless heat pumps work to both heat and cool single spaces or rooms within your home where ductwork is not present. Homeowners can install up to five indoor ductless units throughout their home, all connected to just one outdoor unit, in order to cool multiple spaces at once.
A ductless HVAC system (also called a ductless mini-split or ductless multi-split) is any HVAC system that can heat and/or cool your home without the presence of ducts. Ductless HVAC systems are designed to control the temperature in just one room or space, as opposed to the entire home.
