San Diego's Mediterranean climate creates the perfect conditions for ductless heat pump technology. You need cooling from April through October when inland temperatures hit the 80s and 90s, but coastal areas rarely see extreme heat. Winter temperatures drop into the 50s at night, requiring supplemental heat without the expense of running a gas furnace. Ductless heat pumps operate efficiently down to 40 degrees outdoor temperature, making them ideal for San Diego's mild winters. The coastal humidity also means you need dehumidification during summer mornings when marine layer fog rolls in. Ductless systems dehumidify automatically as they cool, maintaining comfortable indoor conditions without the clammy feeling that comes from undersized central air systems.
San Diego's housing stock ranges from 1920s bungalows in North Park to mid-century ranches in Clairemont and modern construction in Carmel Valley. Many older homes lack the ceiling height and wall cavities needed for traditional ductwork. Adding ducts means lowering ceilings or building bulkheads, which destroys the architectural character of historic homes. Ductless systems preserve original architecture while delivering modern comfort. California's Title 24 energy code also encourages high-efficiency HVAC systems, and ductless mini splits exceed the minimum efficiency requirements. Elite HVAC San Diego helps you navigate local building permits and ensures your installation meets all code requirements for San Diego County.
