The answer to 'should I get ductless system or' is that ductless (or mini-split) HVAC systems can be a great option for many homeowners, especially those with older homes that lack existing ductwork. Ductless systems offer several benefits, including improved energy efficiency, flexible zoning and temperature control, and easier installation compared to traditional ducted systems.
Ductless systems consist of an outdoor compressor/condenser unit and one or more indoor air-handling units that are connected by refrigerant lines. This allows you to cool (or heat) specific rooms or zones independently, which can lead to significant energy savings. They are also quieter and take up less space than traditional HVAC equipment. The installation process is generally less invasive since there is no need to build out extensive ductwork throughout the home.
