AC Repair Cost: Typical Prices for Common Central Air Repairs

AC repair cost is the price to diagnose and fix a central air conditioner, and it depends mostly on which part failed. Typical industry ranges for common repairs:

• Capacitor replacement: commonly about $150 to $400.
• Contactor replacement: typically about $150 to $400.
• Outdoor fan motor: commonly about $400 to $900.
• Refrigerant leak repair and recharge: often about $400 to $1,500 or more.
• Evaporator coil replacement: commonly about $1,500 to $3,000.
• Compressor replacement: often about $1,800 to $4,000.

Small electrical parts are cheap fixes. Refrigerant, coil and compressor problems are where replacement starts to make sense.

Key Takeaways

• Capacitors and contactors are the most common fixes. They are also among the cheapest.
• Refrigerant leaks need a real repair. Topping off without fixing the leak wastes money.
• Big repairs on old units rarely pay off. Use the $5,000 rule.
• Ask for a written price before work starts.

AC Repair Cost by Problem

These are typical industry ranges. Exact cost depends on the model, part availability and access. Not sure what is wrong? Start with central air not blowing cold air.

What Affects AC Repair Cost?

• Part availability: brand-specific parts cost more than universal ones.
• Refrigerant type: R-22 systems are especially costly to recharge since production ended in 2020.
• Access: attic air handlers and tight crawlspaces add labor.
• Timing: after-hours visits typically cost more.
• Warranty: parts under manufacturer warranty may only cost labor.

Should You Repair or Replace?

A common rule multiplies the system's age by the repair cost. If the result tops about $5,000, replacement usually makes more sense.

• A 5-year-old AC with a $300 capacitor: 5 × 300 = 1,500. Repair.
• A 13-year-old AC with a $2,500 compressor: 13 × 2,500 = 32,500. Replace.

See central air replacement cost for typical replacement ranges. New split ACs in northern states must meet at least 13.4 SEER2, and ENERGY STAR certified central air conditioners reach at least 15.2 SEER2.

How to Avoid Expensive AC Repairs

• Change filters every one to three months. Per DOE's air conditioner maintenance checklist, a clean filter can lower AC energy use by 5% to 15%.
• Keep the condenser clear and rinse its coil each spring.
• Book a spring cooling tune-up to catch weak capacitors.
• Clear the condensate drain to prevent water damage. See central air conditioning leaking water.

As of 2026, a yearly tune-up remains the cheapest way to avoid a mid-July breakdown.

Get an Honest AC Repair Price

AC repair cost ranges from a small capacitor fix to a compressor replacement that rarely makes sense on an older unit. A clear diagnosis and a written price let you decide with confidence.
