Definition
A ductless mini-split is a heat pump with an outdoor compressor connected by a slim refrigerant line set to one or more indoor heads mounted on walls or ceilings. Each head heats and cools its own zone without ductwork. Most use variable-speed inverter compressors, and single-zone and multi-zone configurations are both common.
Also called: Mini-split, Ductless heat pump
Why it matters to you.
Many older homes around downtown Danville and Harrodsburg were built without ductwork, and additions, bonus rooms, garages and workshops often sit outside the main system. A ductless mini-split heats and cools those spaces without cutting duct runs through plaster walls and tight framing.
Practical guidance.
Rinse or vacuum the washable filters in each indoor head on the manufacturer's schedule and keep the outdoor unit clear of debris. Line-set, refrigerant charging and electrical connections require a licensed technician.
