Ductless Mini-Split Services
Wall-mounted heating and cooling without ductwork.
Ductless mini-splits provide efficient heating and cooling without requiring ductwork. An outdoor compressor connects to one or more indoor units through refrigerant lines and wiring. Each indoor unit controls its zone independently. Mini-splits excel in homes without ducts, additions, converted spaces, and areas with comfort issues. Multi-zone systems can serve entire homes with individual room control.
How Ductless Mini-Splits Work
Mini-splits work like heat pumps but deliver conditioned air directly to the room without ducts. The outdoor unit contains the compressor. Refrigerant lines connect to wall, ceiling, or floor-mounted indoor units. Each indoor unit has its own air handler and can be controlled independently. This eliminates duct losses and allows precise zone control.

Ductless Mini-Split Maintenance Tips
Efficiency Information
Mini-splits achieve some of the highest efficiency ratings, with SEER ratings from 18 to 30+. Eliminating duct losses adds 20-30% efficiency versus ducted systems. Variable-speed compressors maintain efficiency across conditions. The combination of high equipment efficiency and no duct losses makes mini-splits extremely economical.
Expected Lifespan
Quality mini-splits last 15-20 years with proper maintenance. Indoor units may need replacement before outdoor units. Coastal installations face salt air challenges. Multi-zone systems have more components but also more redundancy.
Bay Area Considerations
Mini-splits are particularly popular in the Bay Area for Victorian homes without ducts, fog belt homes that need only occasional cooling, and additions or ADUs. The high efficiency matches Bay Area energy costs. Multi-zone systems allow different temperatures for sunny and shady sides of homes. Coastal areas benefit from dehumidification features.
