When your air conditioner breaks down, the big question is whether to repair it or replace it. The right answer depends on the system’s age, its condition, how much you’re spending to keep it running and how long you plan to stay in your home. Here’s a practical way to decide.

Quick answer

Repair usually makes sense when the system is relatively new, the problem is isolated and the repair cost is modest. Replacement is often the better value when the system is older, needs repeated repairs, uses an outdated refrigerant or can no longer keep your home comfortable through an Arizona summer.

When repair makes sense

• The system is newer and has been reliable
• The problem is a single part, such as a capacitor, contactor or fan motor
• Your energy bills have stayed steady
• The home cools evenly when the system is working

When replacement is worth considering

• Breakdowns are becoming frequent, especially during peak summer
• Energy bills keep climbing even with regular maintenance
• Some rooms never get comfortable
• The system uses R-22 refrigerant, which is no longer produced or imported in the U.S., so repairs involving refrigerant can be costly
• A major component such as the compressor has failed on an older system

A simple rule of thumb

Some homeowners use the “age times repair cost” rule: multiply the system’s age by the repair estimate. If the result is well above $5,000, replacement is usually worth a serious look. It’s only a starting point — your technician should look at the system’s overall condition, not just one number.

Things to know about newer systems

Federal efficiency standards for new air conditioners were raised in 2023, and the industry is moving to newer, lower-impact refrigerants. In practice that means a new system will typically use less energy than an older one, which matters in a climate where AC runs for months at a time. Ask your installer to explain the efficiency rating and refrigerant of any system you’re considering.

Questions to ask before you decide

• How old is my system, and what is the overall condition beyond this repair?
• Is this repair likely to be the first of several?
• What would a replacement cost, and what financing is available?
• What warranty comes with the repair versus a new system?
