Local conditions that affect your system
Salt air corrosion
Near the coast, salt air corrodes condenser coils and fasteners. Coated coils and regular rinsing extend equipment life.
Adding AC
Heat pumps that replace an old furnace and add cooling are a popular one-step upgrade, often ductless in homes with small attics.
Title 24 permits
California's energy code applies to replacements, so expect a permit and duct leakage testing.
Seasons and peak demand in San Diego
Most of the year San Diego needs little heating or cooling, which is why so many homes skipped AC. The pressure comes in late summer and early fall, when heat waves and dry Santa Ana winds push inland temperatures past 95°F. Contractors book up fast during those stretches, so homeowners planning a heat pump or mini-split usually install in spring.

San Diego HVAC FAQ
Is a heat pump a good fit in San Diego?
Usually, yes. The mild climate is ideal for heat pumps, and one system can replace an older furnace while adding cooling.
How does salt air affect AC units near the coast?
It speeds up corrosion of the outdoor coil and electrical connections. Rinsing the coil a few times a year and choosing coated coils helps.
