AC installation cost by system.
Installed pricing for West Whittier-Los Nietos, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In West Whittier-Los Nietos, where the median home was built in 1954, AC installation often involves retrofitting older ductwork or adding new ducts. For a like-for-like central AC replacement, local pricing typically ranges from $4,000 to $7,900+, while a full system with new ductwork can run $5,900 to $12,900+.

Common AC installation issues in West Whittier-Los Nietos
Aging ductwork
Many homes from the 1950s have undersized or leaky ducts that must be repaired or replaced to meet current efficiency standards.
Permit and code compliance
California requires a mechanical permit, Manual J load calculation, and HERS-verified duct leakage testing, which can delay installation if not planned for.
Refrigerant transition
New systems use R-454B or R-32 refrigerant (R-410A phased down after 2025), so older units may need disposal and system upgrades.
