AC installation cost in San Diego depends on whether you choose a standard 14.3 SEER2 split system or a variable-speed, high-efficiency system (18+ SEER2), which costs meaningfully more. Permit fees, line set length, and electrical upgrades affect the final number too. The company you're matched with gives you line-item pricing broken out by equipment, labor, materials, permit, and warranty before anything is ordered.

What size AC do I need?

Smaller than a contractor's rule of thumb, usually. Every home gets a Manual J load calculation that accounts for square footage, insulation, window type, orientation, and ceiling height. Oversized systems short-cycle, leave humidity, and wear out faster. Rightsized wins on comfort and bills.
