A reader in Greece, just outside Rochester, forwarded me two quotes last week for the same three-ton replacement. One was $9,850. The other was $7,400, and the cheap one had a handwritten note on it: "EPA lifted the ban — we can still use 410A equipment." That is half true, and the half that is false is the half that matters in New York.
EPA did change its mind. In a final rule that took effect July 27, 2026, the agency allowed continued installation of units manufactured or imported before January 1, 2025 that use R-410A, until the remaining supply runs out. That reversed the one-year sell-through cutoff everyone had been planning around. But EPA's rule sets a national floor, not a ceiling, and New York built its own.
What Part 494 actually says
6 NYCRR Part 494 is the DEC regulation that carries New York's hydrofluorocarbon phasedown. The residential air conditioning piece tracked the original federal schedule: equipment manufactured before January 1, 2025 could be installed through January 1, 2026, and after that date any newly installed unit has to use a refrigerant with a 100-year GWP below 700.
R-410A has a GWP of about 2,088. It is not close. R-454B lands near 466 and R-32 near 675, which is why those two are what you will actually be offered.
When EPA loosened the federal deadline in May and made it effective in July, Part 494 did not move with it. The state rule is the stricter one, and stricter state rules survive federal relaxation. The practical result is a genuine two-tier market right now: a Pennsylvania or Ohio contractor can legitimately work through leftover R-410A inventory at a discount, and a New York contractor cannot.
One real exception, and salespeople blur it. New York's sell-through for packaged residential air conditioners and rooftop units runs a year longer — packaged R-410A equipment built before January 1, 2026 can be installed until January 1, 2027. Packaged means the whole system is in one cabinet, typically on a flat roof or a slab. If you have a conventional split system with an outdoor condenser and an indoor coil, that extension is not yours, and "there's an exemption" is not an answer to the question.
How to tell what you're actually being quoted
Nobody writes "R-410A" in bold on a proposal. Here is what to check, in the order that takes the least effort:
- Ask for the AHRI reference number of the matched system, not just the outdoor model. The AHRI certificate lists the refrigerant. This is a thirty-second lookup and it ends the argument.
- Look at the trade name. Carrier and Bryant sell R-410A as Puron and R-454B as Puron Advance — one word apart, and easy to skim past on a quote line.
- Look for a leak sensor line item or mention. A2L systems certified to UL 60335-2-40 include refrigerant detection and mitigation. If the proposal for a ducted system says nothing anywhere about a sensor, ask why.
- Be suspicious of a number that is two thousand dollars under everyone else. In September 2026 that gap usually means either old-refrigerant stock or a missing piece of scope, and both are worth naming out loud.
If a contractor confirms the equipment is R-410A and tells you it is fine because of the EPA change, you now know enough to say: New York didn't adopt that. Whether they argue or correct themselves tells you a lot about the rest of the job.
Keeping the system you have is still legal — it's just expensive
None of this forces anybody to rip out working equipment. Servicing existing R-410A systems remains legal in New York and nationally. There is no deadline on your condenser.
The change is in the invoice. R-410A production was cut hard at the start of 2025 and the service supply now depends on remaining stock and reclaimed refrigerant. Wholesale pricing moved from roughly $8 to $12 a pound a few years ago into the $25 to $45 range, and installed billing on a service call — refrigerant, recovery, leak search, labor — commonly runs $50 to $90 a pound.
That reframes the repair-versus-replace question for anyone with a leak:
| Scenario, 4-ton system | 2023 | Fall 2026 |
|---|---|---|
| Top-off, 2 lb, no repair | ~$220 | $310–$430 |
| Evaporator coil leak: coil + full recharge (~9 lb) | $1,300–$1,800 | $2,100–$2,900 |
| Compressor failure, out of warranty | $2,200–$3,200 | $2,900–$4,200 |
| Full A2L replacement, matched system | n/a | $9,000–$14,500 |
Ranges vary by market — Long Island and Westchester run above Buffalo and Syracuse on labor for the same work. But the shape holds: a repeat top-off on a system that leaks every summer has stopped being the cheap option. Two of those calls plus a diagnostic now buys a meaningful slice of a real replacement. My rule of thumb this year is that a second refrigerant call on the same system within eighteen months should trigger a replacement quote, not a third can.

Compare NY HVAC quotes →The one upside: this is the year to stop buying cooling-only
If you are being pushed into new equipment anyway, the marginal cost of choosing a heat pump over a straight air conditioner is smaller than most homeowners assume. It is the same line set, the same pad, the same electrical, the same crew-hours. The difference is the outdoor unit and the controls.
And only one of those two choices collects money back. NY Clean Heat utility incentives attach to heat pumps, not to cooling-only condensers. Paying the A2L premium and the 2026 labor rate for a box that can only cool, in a year when the alternative is a few hundred dollars more and rebate-eligible, is the most expensive decision available on that quote sheet. Our NY Clean Heat rebate breakdown covers the qualifying tiers, and the Clean Heat contractor page lists installers enrolled in the program — enrollment matters, because an unenrolled contractor cannot file your incentive.
Two cautions on that. Cold-climate performance ratings, not nameplate capacity, are what to compare for anything north of the Hudson Valley — look at rated capacity at 5°F, and read our cold-climate heat pump notes before you compare models. And do not let a heat pump upsell postpone envelope work; sizing equipment before air sealing gets done is how people buy a system a size too big.
Five questions for the contractor, before you sign
- "What refrigerant, and what's the AHRI reference number for the matched pair?" Get both numbers on the proposal, not in a text message.
- "When was this equipment manufactured?" Pre-2025 build dates on a split system quoted in New York are a direct red flag.
- "Where does the A2L leak sensor live on this install, and what does it do when it trips?" A technician who cannot answer this has not done many of these yet.
- "Are you enrolled with my utility for NY Clean Heat?" Ask before the heat pump conversation, not after.
- "Is the indoor coil being replaced?" Matched A2L equipment means both halves. A new condenser on an old R-410A coil is not a thing.
For broader context on equipment tiers and what drives installed pricing, the HVAC service hub walks through the cost structure, and what HVAC replacement actually costs breaks down a quote line by line. If you want local screening, start from the New York HVAC page or go straight to Buffalo, Rochester, Syracuse or Albany. Downstate, the Long Island and Westchester County pages are the right entry points. And if you are still deciding whether this is a repair year or a replacement year at all, our repair-or-replace framework lays out the thresholds.
The reader in Greece went back to the cheaper contractor with the AHRI number question. The quote came back four days later at $9,600 with R-454B equipment. Same company, same crew, $2,200 higher — which tells you exactly what the first number was.
Frequently asked questions
Can a contractor legally install an R-410A air conditioner in New York in 2026?
Not a residential split system. New York's 6 NYCRR Part 494 allowed R-410A equipment manufactured before January 1, 2025 to be installed through January 1, 2026, and after that date newly installed residential air conditioning and heat pump equipment has to use a refrigerant with a 100-year GWP under 700. EPA relaxed the equivalent federal deadline in a final rule effective July 27, 2026, but a federal relaxation doesn't override a stricter state rule. Packaged residential units and rooftop units are the one wrinkle: those got their own sell-through in New York running to January 1, 2027.
Is it still legal to repair and recharge my existing R-410A system in New York?
Yes. Neither the federal rule nor Part 494 requires anyone to remove or stop servicing equipment already in the field. You can add refrigerant, replace a compressor, fix a coil leak. What changed is the price — R-410A production was cut sharply in 2025 and the service market now leans on reclaimed and remaining stock, so per-pound pricing has climbed well above where it sat two years ago.
What does R-410A actually cost per pound now?
Wholesale has moved from the roughly $8 to $12 per pound range of a few years ago into the $25 to $45 range, and installed billing on a service call commonly lands between $50 and $90 per pound once recovery, leak search and labor are bundled in. That's why a coil leak on a five-ton system can turn into a four-figure invoice: an eight to twelve pound recharge is no longer a rounding error on the ticket.
Can my R-410A system be converted to R-454B?
No. R-454B runs at different pressures, uses a different oil and requires A2L-rated components, service equipment and leak detection. There's no retrofit path for a residential R-410A condenser and coil. When the equipment reaches end of life, both the outdoor and indoor units get replaced together with matched A2L equipment.
Is R-454B dangerous because it's flammable?
R-454B is classified A2L, which means mildly flammable with a low burning velocity. It is not propane. The safety case is handled in the equipment design rather than left to the homeowner: systems certified to UL 60335-2-40 carry refrigerant detection and mitigation logic that shuts the system down and runs the blower if refrigerant is sensed indoors. The practical homeowner consequence is that A2L work requires a technician with current training and A2L-rated tools, which narrows the pool of who should be touching the system.
Does the New York rule apply to ductless mini splits too?
Yes — the GWP threshold applies to residential air conditioning and heat pump equipment broadly, not just ducted splits. In practice ductless is the easiest category to comply in, because most ductless manufacturers moved to R-32 at a GWP of roughly 675 years ago and R-32 sits under the 700 ceiling.
If I have to buy A2L equipment anyway, should I switch from AC to a heat pump?
It's the right year to run the numbers. The condenser, the line set connections, the electrical and the labor are largely the same job whether the outdoor unit is a straight air conditioner or a heat pump, and the heat pump version is what qualifies for NY Clean Heat utility incentives. If you're paying for A2L equipment and an A2L-competent crew either way, buying a cooling-only box means paying the same premium and collecting none of the rebate.
