Repair or replace an R-410A AC or heat pump in 2026
If your central air or heat pump was installed before 2025, it almost certainly runs on R-410A. The rules around that refrigerant changed again in 2026, and they affect how you should weigh a big repair against a new system.

Quick answerYour R-410A system is still legal to run, repair and recharge. New R-410A systems stopped being made in 2025, and a May 2026 EPA rule lets remaining pre-2025 equipment be installed until it runs out. Repair makes sense for a leak-free system with a small fault; a large leak, a failed compressor or an aging system usually points toward a new A2L system.
What actually changed
Manufacturing and import of new R-410A residential and light-commercial AC and heat pump systems stopped on January 1, 2025. New systems now use lower-impact A2L refrigerants such as R-454B and R-32.
The original rules also set a January 1, 2026 deadline to install leftover R-410A equipment. A May 2026 EPA final rule removed that deadline for equipment made before 2025, so remaining inventory can still be installed until it runs out.
Your system is still legal to run
Nothing requires you to replace a working R-410A system. Servicing, repairing and recharging existing R-410A systems remains legal with no end date.
What does change is cost. As production of R-410A is phased down, the refrigerant is expected to get more expensive, so the price of a leak that needs repeated recharges keeps rising.
When repair makes sense
If the system holds its charge and the problem is a capacitor, contactor, fan motor, sensor or control board, repair is almost always the right call. These parts are not tied to the refrigerant.
A small, findable leak at a valve or flare fitting can also be worth fixing, as long as the repair holds and the system is not near the end of its life. Our refrigerant leak repair work starts by finding the leak, not just topping it off.

A failed compressor, a leaking indoor or outdoor coil on an older system, or a system that needs refrigerant every season usually tips the math toward replacement. Each recharge costs more than the last, and the repair does not add years to the rest of the equipment.
Age matters too. A system past about 15 years that needs a major refrigerant-side repair is a strong candidate for a new central AC or heat pump.
- Compressor failure on an older system: replace.
- Coil leak that keeps returning: replace.
- Needs refrigerant every year: replace.
- Capacitor, fan motor or control fault: repair.
You cannot mix old and new
A2L refrigerants cannot be put into an R-410A system, and a new A2L outdoor unit has to be matched with an indoor coil designed for it. So if the outdoor unit fails on an older system, replacing just that half usually means replacing the indoor coil too.
If the furnace is also old, that is the moment to price the whole system together.
Rebates and credits in 2026
The federal 25C efficiency tax credit ended after December 31, 2025, so it no longer offsets a 2026 replacement. Utility rebates may still apply to some heat pumps and high-efficiency equipment; our guide to Avista rebates covers what to check before you buy.
Questions to ask on a quote
A good quote answers the refrigerant question plainly:
- Does this repair touch the refrigerant side, and how much refrigerant is involved?
- Was the leak found and fixed, or just topped off?
- If replacing, which refrigerant does the new system use?
- Does the price include a matched indoor coil and the permit?

R-410A and refrigerant questions
Is R-410A banned in 2026?
No. New R-410A systems stopped being made in 2025, but existing systems can be serviced and recharged, and pre-2025 inventory can still be installed.
Will I be able to get R-410A for repairs?
Yes. Servicing existing systems with R-410A remains legal, though prices are expected to rise as supply is phased down.
Can my R-410A system be converted to a new refrigerant?
No. A2L refrigerants require equipment designed for them.
Should I replace a working R-410A system now?
Not just because of the rules. Replace when a major repair or repeated leaks make it the better value.
If my outdoor unit dies, can I replace only that?
On an older R-410A system, a new outdoor unit usually needs a matching new indoor coil.
