AC Refrigerant Recharge Cost (2026): R-410A, R-22 and Leak Repair

An AC recharge is priced by refrigerant type and the number of pounds added, plus the diagnostic and leak-search labor. A system low on refrigerant has a leak — recharging without addressing it is a temporary fix, and the estimate should say so.

What does an AC recharge cost?

A recharge on a modern R-410A system typically runs $150 to $500 depending on how many pounds are needed. Older R-22 systems run $200 to $800 or more because R-22 is expensive and scarce. A full recovery, evacuation, and recharge after a repair runs $400 to $900.

Why should the estimate address the leak?

• Refrigerant is a closed loop — it does not get "used up," so low charge means it escaped
• Recharging a leaking system means the customer pays again in weeks or months
• Adding refrigerant to a system with a compressor or metering-device problem can mask a failure and lead to a bigger repair

Quote the recharge together with a leak search, and present leak repair as the real fix — a line-set repair, a coil replacement, or a Schrader valve, each with its own price.

How do you price the leak search?

A dye or electronic leak search is $100 to $300. Evaporator coil leaks often mean coil replacement at $600 to $2,000; condenser coil or line-set leaks vary widely. Give the customer the decision with numbers: recharge-and-monitor versus find-and-fix.

What should you never do on the estimate?

Do not quote a bare recharge as if it solves the problem. State the system is low, that indicates a leak, and that a recharge alone is a stopgap. That honesty is what earns the repair job and the repeat customer.

Example: present two options, not one

Option	Includes	Example
A: Recharge and monitor	Diagnostic, add 3 lb refrigerant, note that a leak is present	$385
B: Find and fix	Diagnostic, electronic leak search, repair accessible leak, evacuate and recharge	$895

Illustrative numbers only. Use your own rates, production times and local costs.

Presenting both lets the customer choose with full information. Many choose to fix the leak once they understand a recharge alone may not last.

Refrigerant rules to keep in mind

Refrigerant handling is regulated. In the US, technicians who work with refrigerants generally need EPA Section 608 certification, and refrigerant must be recovered rather than vented. Newer systems are also moving to lower-impact refrigerants, which can affect parts and pricing. When older R-22 systems need large repairs, it's often worth showing replacement as an option. See HVAC installation cost and how to price HVAC jobs.

Frequently asked questions

How much does it cost to recharge an AC unit?

A recharge on an R-410A system commonly runs about $150 to $500 depending on how much refrigerant is needed. Older R-22 systems cost more.

Does an AC need refrigerant every year?

No. Refrigerant runs in a closed loop. A system that needs refrigerant has a leak.

How long does an AC recharge last?

Without a leak repair, it depends on how fast the leak is. It could be weeks or a season. Fixing the leak is the lasting solution.
