Yes, central air conditioning systems can be installed in houses without ducts. There are two main types of central air conditioning systems that can be used in ductless houses:
Ductless Mini-Split Systems: Ductless mini-split systems consist of an outdoor compressor unit and one or more indoor air handlers. These air handlers are mounted on walls or ceilings in individual rooms or zones. They are connected to the outdoor unit through refrigerant lines and require only a small hole to pass the lines from the outside to the inside of the house. Each indoor unit can be controlled independently, allowing for zoned cooling and greater energy efficiency.
Ducted Mini-Split Systems: These systems are similar to ductless mini-splits, but they also offer the option to use ducts. Ducted mini-splits use a central air handler that can be connected to ductwork to distribute conditioned air throughout the house. However, they can also operate as a ductless system by using the indoor air handler without ducts.
Ductless mini-split systems have several advantages for houses without existing ductwork:
Easy installation: Since they don't require extensive ductwork, the installation process is typically faster and less invasive.
Zoned cooling: Each indoor unit can be controlled independently, allowing for personalized temperature settings in different rooms or zones.
Energy efficiency: Ductless systems can be more energy-efficient than traditional central air conditioning systems with ducts because there are no duct losses.
Versatility: Ductless systems are suitable for a variety of house types, including older homes, additions, or areas where it's challenging to install ductwork.
Quiet operation: Ductless systems are known for their quiet operation since the noisiest components are located in the outdoor unit.
If you have a house without ductwork or want to add cooling to specific areas, a ductless mini-split system could be an excellent option to consider. However, it's essential to have a professional HVAC technician assess your home and determine the most suitable cooling solution based on your specific needs and the layout of your house.
