How much does it cost to replace a central air conditioner?

Most homeowners pay roughly $4,500–$9,500 for a complete central AC replacement (condenser, coil, and installation), within a broader range of about $3,500 on the low end to $12,000+ for large or high-efficiency systems. The main drivers are system size, efficiency rating, and whether ductwork needs work.

Is it cheaper to replace just the AC or the whole HVAC system?

Replacing only the AC (condenser + coil) is cheaper than a full HVAC replacement that also swaps the furnace or air handler. But if both are near end of life, replacing them together usually costs less than doing two separate jobs later — and the components stay matched.

What's the most expensive part of an AC replacement?

Roughly half the cost is the equipment (condenser and coil); the rest is labor, permits, refrigerant, and any electrical or duct work. Replacing ductwork is the single biggest add-on when it's needed.

How long does a central AC unit last?

A well-maintained central air conditioner typically lasts 12–17 years. If yours is over about 15 years old and needs a major repair, replacing it is often the better value.

How we localized this

We start from our national central air conditioner replacement range of $3,500–$12,000 and adjust it for Los Angeles, where costs run about 13% above the national average. Los Angeles is one of the priciest U.S. metros for home work: construction labor runs roughly 17% above the national average and local construction-cost indices land about 14–20% higher. Because materials are priced roughly nationally everywhere, the effective home-improvement premium is somewhat lower than the headline index — we apply about 13%. Strict permitting and inspections add further time and cost. Materials are priced roughly nationally, so treat this as an approximation — your actual price depends on your home, contractor, and project specifics.

Los Angeles is among the most expensive U.S. metros for home work. Construction labor runs well above the national average, and strict permitting and inspections — including seismic requirements and California's Title 24 energy rules — add both time and cost. Permit timelines can be long, so budget for them. Demand for upgrades like 200-amp panel replacements is high as homes add EV chargers and electrify.
