Mild, marine-influenced weather near the coast; hotter, drier inland valleys; and Santa Ana wind events that bring heat and fire risk.
Permits and seasonal timing in San Diego
The City of San Diego's Development Services Department issues mechanical permits in the city, and Chula Vista, El Cajon and other cities have their own. Title 24 duct testing typically applies to replacements. Coastal homes usually need cooling only during heat waves, while inland neighborhoods should schedule AC maintenance before summer.
