R-410A, the refrigerant used in most Central Florida air conditioners installed over the last two decades, is being phased out, but not in the simple, single cutoff date way a lot of homeowners have heard. Manufacturers stopped building new R-410A air conditioners and heat pumps on January 1, 2025, and the EPA has since adjusted the rules on installing leftover units more than once, most recently in May 2026. Here is what has actually changed, what has not, and what it means if your Lake Mary area system needs a repair.

What Actually Changed With R-410A

Under the EPA’s AIM Act rules, manufacturers were required to stop producing new residential split system air conditioners and heat pumps charged with R-410A as of January 1, 2025. New equipment built after that date uses a lower global warming potential refrigerant instead, most commonly R-454B or R-32.

That part of the timeline has not changed. What has changed is what happens to the R-410A equipment that was already manufactured before that cutoff:

• The original rule set a January 1, 2026 deadline to install any remaining pre-2025 R-410A units
• In May 2026, the EPA issued a final rule removing that installation deadline for residential and light commercial systems
• As a result, a pre-2025 R-410A system can still legally be installed today, as long as it was manufactured or imported before January 1, 2025, until existing supplies run out

In other words, the rules have moved twice in under two years. If you read something online about a hard 2026 cutoff for installing R-410A equipment, it was accurate at the time but is no longer the current rule.

Can You Still Get Your Existing AC Serviced

Yes. None of these changes affect servicing a system you already own. R-410A refrigerant and the parts used to repair existing R-410A systems, such as condensing units and indoor coils, remain available specifically for maintaining legacy equipment. There is no rule requiring you to replace a working R-410A system, and a licensed technician can still legally diagnose, repair, and recharge it.

What the rules do restrict is using R-410A components to build a brand new R-410A system going forward. That distinction matters: servicing what you have is unaffected, starting a new R-410A installation from scratch generally is not an option anymore outside of existing pre-2025 inventory.

Why Refrigerant Repair Costs Are Climbing

Even though R-410A is not banned for servicing, its production is being phased down on a fixed schedule under the AIM Act, decreasing year by year toward a small fraction of current output by the mid 2030s. Less supply chasing the same number of aging systems tends to push prices up, and that has already been happening industrywide.

• A R-410A recharge that cost roughly $150 to $300 a few years ago is now commonly running $300 to $600 or more
• A full recharge on a larger residential system, which can require 6 to 12 pounds of refrigerant, can run $500 to $1,500 depending on the system and the going rate for refrigerant at the time
• This mirrors what happened with R-22, the refrigerant R-410A itself replaced: once production was restricted, prices climbed from around $20 a pound to well over $150 a pound within a few years

These are general industry ranges, not a quote, since actual pricing depends on the system size, the extent of the leak, and current refrigerant availability at the time of service. The practical takeaway is that a repair involving a significant refrigerant recharge is likely to cost more this year than it would have two or three years ago, and that trend is expected to continue as supply keeps shrinking.

Repair or Replace: How to Think About It Now

Rising refrigerant costs change the math on repair versus replacement for an aging R-410A system, especially one with a refrigerant leak rather than a one time component failure.

• A failed capacitor, fan motor, or similar part is still generally worth repairing regardless of refrigerant type, since it does not involve a recharge
• A refrigerant leak on an older system is where the calculation is shifting, since a leak often means paying for both the leak repair and a full recharge at today’s higher refrigerant prices
• If your system is already 10 to 12 years old or older and develops a refrigerant leak, it is worth asking your technician for the repair cost and the replacement cost side by side before deciding, rather than assuming repair is automatically cheaper

Our technicians can walk through both numbers during a repair visit, and our financing options are available if replacement turns out to be the better long term value.

What This Means If You Are Buying a New System

If you are installing a new system rather than repairing an old one, you will almost certainly be getting an A2L refrigerant such as R-454B or R-32 rather than R-410A, since new R-410A equipment is no longer being manufactured.

A2L stands for Class A2L under ASHRAE’s refrigerant safety classification, meaning low toxicity and low flammability. These refrigerants were specifically developed to have a much lower global warming potential than R-410A while still being safe for standard residential use when installed and serviced correctly:

• R-410A has a global warming potential of 2,088
• R-454B, the most common R-410A replacement, has a global warming potential of 466, about 78 percent lower
• Installing and servicing A2L systems requires technicians to hold updated safety certification, since the refrigerant carries a mild flammability rating that R-410A does not

This is not a reason to delay a needed replacement. A2L systems have been installed across the country since 2025, and our maintenance plans cover both A2L and legacy R-410A systems.

Frequently Asked Questions

Do I have to replace my AC if it uses R-410A

No. There is no requirement to replace a working R-410A system. It can continue to be serviced, repaired, and recharged by a licensed technician.

Is it still legal to install an R-410A air conditioner in 2026

Yes, if the system was manufactured or imported before January 1, 2025. The EPA removed the earlier installation deadline in a May 2026 rule, so pre-2025 R-410A inventory can still legally be installed.

Why did my AC repair quote go up compared to a couple years ago

If the repair involves a refrigerant recharge, R-410A prices have risen as production is phased down under federal rules. Repairs that do not involve refrigerant, like a capacitor or fan motor replacement, are not affected the same way.

What refrigerant is used in new air conditioners now

Most new residential systems use R-454B or R-32, both A2L refrigerants with a significantly lower global warming potential than R-410A.

Is A2L refrigerant safe for my home

Yes. A2L refrigerants are classified as low toxicity, low flammability under ASHRAE standards, and technicians installing or servicing them are required to hold updated safety certification.
