What Affects AC Installation Costs?

1. System size (tonnage) — A 1.5-ton unit for a small condo costs $3,000–4,500, while a 5-ton unit for a large home runs $6,000–10,000.
2. SEER rating — Higher efficiency (16–20+ SEER) units cost more upfront but save 20–40% on energy bills. San Diego's mild climate makes 14–16 SEER a good value sweet spot.

How to Save on AC Installation

Install in off-season — October through March sees 15–25% lower installation prices than peak summer months.
Don't oversize — A unit that's too large cycles on and off frequently, wasting energy and wearing out faster. Trust a Manual J load calculation.
Check for rebates — SDG&E and federal tax credits offer $300–2,000 for high-efficiency heat pump and AC installations.
