What Is the Typical Cost to Replace an AC Unit?

When your AC gives up in the middle of a sweltering Las Vegas summer, you’re replacing an appliance and restoring sanity. But how much should you expect to spend when the cool air cuts out for good?

On average, homeowners in the United States pay between $4,000 and $12,000 for a complete AC replacement. The wide range reflects differences in unit sizes and types, installation complexity, and the layout of an individual’s home.

Some units cost more upfront but save you money over time. Other HVAC systems are cheaper to install but drain energy bills quickly. The right choice is less about budget and more about fit, function, and long-term efficiency.

National Average Replacement Costs by Unit Type

The type of system you choose significantly impacts the final cost. More features mean more flexibility, but more upfront costs.

A standard central AC system, common in homes with existing ductwork, typically runs $3,500 to $7,800.

Ductless mini-splits, which don’t rely on ducts and allow for zoned cooling, range from $5,000 to $25,000, depending on how many indoor units you need.

Heat pumps, which cool and heat your home, can start around $8,000 and reach $15,000 (or more).

Cost Breakdown: Equipment, Labor, and Permits

An AC unit is one piece of the total bill. Labor typically adds $1,250 to $3,000, depending on how complex the installation is. Labor costs climb if you’re replacing ductwork, upgrading electrical systems, or dealing with tight crawlspaces.

Permits are another overlooked line item. Most cities require one for HVAC installation, and fees can range from $100 to $1,500, depending on labor codes.

A transparent quote should itemize equipment, labor, and legal requirements.

SEER Ratings and Efficiency Upgrades: Worth the Extra Cost?

Efficiency ratings matter, especially if you’re cooling a home through long, hot seasons. Units are rated by SEER (seasonal energy efficiency ratio), and higher numbers mean lower energy usage.

For example, a 14 SEER unit meets basic standards, but upgrading to 17 SEER or more could significantly reduce utility costs. Depending on local rates and climate, moving from a 14 to a 17 SEER may save you around $60 to $100 annually.

The higher the SEER, the higher the price.

Cost Differences Between Split Systems, Central AC, and Heat Pumps

A traditional split or central AC system is the most cost-effective choice if your home already has ductwork. Mini-split systems are ideal for older homes or room-by-room upgrades but come at a higher price per zone.

Heat pumps offer year-round climate control and are efficient in milder climates. They tend to cost more initially but can replace your AC and furnace to cut future maintenance in half.

How to Finance a New AC Unit Without Breaking the Bank

Few people plan for AC replacement, and even fewer want to pay for everything simultaneously. Fortunately, many HVAC providers offer financing options that break down costs into monthly payments. Federal tax credits and local utility rebates can also soften the blow, especially for energy-efficient units.
