R-410A recharge calls: What to say in late 2026
"Can you just top it off?"
The call usually starts the same way. The AC is blowing warm, the homeowner read somewhere that R-410A was banned, and they want to know two things: Can you still recharge it, and how much is refrigerant now. Much of what they read online is out of date, and several pages still say R-410A systems can no longer be installed after January 1, 2026. That changed in May.
A desk that answers from the same outdated pages, or quotes a per-pound price to get off the phone, books the wrong job. This post sets out what is true as of October 2026 and the script that turns the call into a booked diagnostic.
The rules, dated October 2026
Every fact below was checked on EPA and Federal Register pages in October 2026. Put the date in your script, because the rule is still being litigated.
Under the AIM Act, HFC production and imports are capped at 60% of the historic baseline for 2024-2028 and 30% for 2029-2033, according to EPA. Less R-410A is made each year.
Since January 1, 2025, new residential air conditioners and heat pumps must be made or imported with a refrigerant with a global warming potential of 700 or less, according to EPA's sector rules.
EPA's reconsideration rule, published in the Federal Register on May 26, 2026 and effective July 27, 2026, removed the January 1, 2026 installation deadline. Equipment made or imported before 2025 can still be installed.
EPA states owners can keep using and repairing existing systems, "including replacing a major component like a condensing unit or compressor."
Industry groups have filed petitions in the D.C. Circuit, according to ACHR News, though those petitions target the commercial refrigeration provisions. For a homeowner with a working R-410A system, the honest answer is simple: Yes, it can be repaired, and refrigerant is still available.
Why a recharge is the wrong thing to book
An AC is a sealed system. It does not use up refrigerant the way a car uses gas. If it is low, it leaked. A technician who adds refrigerant without finding the leak has fixed the symptom, and the homeowner will call again in a few weeks, angry that they paid twice.
That is why "just top it off" is a trap for the desk too. Book a diagnostic with a leak check, never a recharge. The technician decides on site whether the fix is a recharge, a leak repair, a component, or a replacement conversation.
The script, line by line
Caller says | CSR says | What gets booked |
|---|---|---|
"Isn't R-410A banned?" | No. Existing systems can be repaired and recharged, and refrigerant is available. | Diagnostic with leak check |
"Can you just recharge it?" | We can, once we know why it is low. A system only loses refrigerant through a leak. | Diagnostic with leak check |
"How much is refrigerant?" | It depends on the leak and how much the system needs. The tech gives you the full price before any work. | Diagnostic, fee stated |
"Should I just replace it?" | Maybe. How old is the system? We can have a comfort advisor walk through both options. | Comfort advisor visit if older |
"Someone said I have to replace it by law." | That is not correct. You can keep using and repairing your system for its full life. | Diagnostic |
Why the desk should never quote a pound
Refrigerant prices move because supply is being cut by law, and the amount a system needs is unknown until a technician measures it. A CSR who quotes a per-pound number has set a price the technician cannot hold, and every difference becomes a dispute on the invoice. The same trap shows up on rebate calls, which our post on heat pump rebate calls covers. Quote the diagnostic fee you publish, explain what it includes, and stop there.
The age question opens the bigger conversation
Add one question to every refrigerant call: How old is the system? A three-year-old unit with a leak is a repair. A system past roughly 12 years that has been recharged before is a candidate for a comfort advisor visit, set by your own routing rule rather than an industry number. Never use the rules to push a replacement. The homeowner will find out the system was legal to repair, and the trust is gone.
Revin's voice agent answers every call at once, with no hold queue, so the first hot week does not send refrigerant callers to voicemail. It is trained on your own call recordings and your approved script, gives the same dated answer on every call, books the diagnostic or comfort advisor visit into ServiceTitan while the caller is on the line, and transfers the unusual cases to your team. Your CSRs keep the calls that need judgment.
Can you still buy R-410A refrigerant in 2026?
Yes. The AIM Act phases down how much HFC refrigerant can be produced and imported, but it does not ban using or servicing existing R-410A systems. EPA states that owners can keep using and repairing legacy systems. Supply is shrinking over time, so prices can move, but licensed technicians can still buy R-410A and use it to repair existing equipment.
Is R-410A being banned?
Not for systems already installed. Since January 1, 2025, new residential air conditioners and heat pumps must be made or imported with refrigerants with a global warming potential of 700 or less. A May 2026 EPA rule also lets contractors keep installing R-410A equipment built or imported before 2025. Existing systems can be used and repaired for their full life.
Can you put R-454B in an R-410A system?
No. R-454B is not a drop-in replacement for R-410A. Newer systems are designed for R-454B, which is mildly flammable and runs at different conditions, so the equipment, components, and safety features are built around it. An R-410A system should be repaired with R-410A. Switching refrigerants means replacing equipment, which is a conversation for a comfort advisor rather than the phone.
Should I replace my AC because of R-410A?
Not because of the rules alone. You can legally repair and recharge an R-410A system for its full life. Replacement makes sense when the system is old, needs a major repair, or keeps leaking, because refrigerant supply will tighten as the phasedown continues. A technician can find the leak and give you the repair cost, so you can decide on real numbers.
Why is AC refrigerant so expensive now?
The AIM Act cuts the amount of HFC refrigerant that can be produced and imported to 60% of the historic baseline through 2028 and 30% from 2029. Less supply of older refrigerants pushes prices up and makes them move more often. That is why most contractors will not quote refrigerant cost by phone. The total depends on the leak and how much the system needs.
