Ductless AC mini-split heating and cooling units are among the most efficient systems on the San Diego market today. They make a good retrofit add-on to houses with non-ducted heating systems (such as wall or floor furnaces) and also have proven to be a good choice for conditioning room additions where extending or installing new ductwork is not feasible.
Like standard air-source heat pumps, mini splits have two main components — an outdoor compressor/condenser and an indoor air-handling unit. The main difference with ductless air conditioning San Diego is that their is no ductwork like a traditional heating cooling system. Instead each space has its own thermostat and separate indoor unit making for a much quieter, more efficient design and delivery system..
