What drives AC replacement cost in LA.
- →Tonnage — biggest single factor. Don’t oversize. Manual J calculation gets it right.
- →Brand tier — Goodman (value), Trane (mid), Daikin/Bosch/Mitsubishi (premium). Premium tier delivers 30-50% lower operating cost over 15 years.
- →Ductwork condition — old or leaky ducts add $1,500-$4,000 for sealing or replacement.
- →Electrical capacity — older LA homes (pre-1985) often need panel upgrade for variable-speed equipment ($1,800-$3,500 add).
- →Coastal vs inland — coastal LA homes (Santa Monica, Manhattan Beach, Malibu) need coastal-rated equipment with marine-grade coatings — typically $300-$800 premium.
- →Tonnage above 3.5T — California Title 24 requires HERS testing on systems above certain thresholds ($150-$300 add).
