The R-410A Phase Out: What It Means for Greeley AC Owners (and When to Replace)

Greeley summers are unforgiving. Front Range summers regularly top 90°F, leaving Greeley residents entirely dependent on air conditioning. When federal regulators changed AC manufacturing and servicing standards, local homeowners had every reason to pay attention.

That change is the R-410A phase out, and if your home runs on a central AC system installed in the last 15 years, this affects you directly. In 2026, no newly manufactured residential equipment uses R-410A refrigerant. 

The cost to service older units is climbing fast. Expect refrigerant recharge costs of $300 to $600 or more this season, up from $150 to $300 just a few years ago.

What Is the R-410A Phase Out?

R-410A is the refrigerant found in most residential central AC systems installed across the U.S. since the late 1990s.

It replaced R-22 (Freon), which was phased out for ozone-depleting properties; now R-410A is facing its own sunset.

Under the AIM Act (American Innovation and Manufacturing Act), the EPA classified R-410A as a high-GWP refrigerant.

With a Global Warming Potential of 2,088, it is more than 2,000 times more potent than CO₂.

Effective January 1, 2025, U.S. manufacturers were banned from producing new R-410A equipment.

While R-410A won’t vanish overnight, contractors can only sell and install existing warehouse inventory until supplies run out.

Fortunately, homeowners can legally keep, operate, and service their current systems indefinitely.

Still, this regulatory shift is already actively reshaping the local HVAC.

Is R-410A Being Phased Out for Good?

Yes.

While servicing existing R-410A systems remains legal in 2026, shrinking domestic supplies are driving up refrigerant costs each season.

If your unit needs frequent AC repair, recharges, leak fixes, or compressor repairs, those service bills will climb as stockpiles tighten.

What Is the New Refrigerant for Air Conditioners?

The leading replacement is R-454B, an A2L refrigerant with a GWP of 466, which is 78% lower than R-410A. 

Most major manufacturers, including Armstrong Air (McCormick’s authorized brand), now build all new residential equipment exclusively around R-454B.

When comparing R-410A vs. R-454B, cooling performance is comparable, but the hardware is not interchangeable.

The AC condensers, coils, and refrigerant lines in A2L systems are purpose-engineered for R-454B.

You cannot retrofit an existing R-410A unit to run on the new refrigerant.

A new A2L-refrigerant AC installation from McCormick includes a 10-year limited parts warranty.

This also has a 3-year craftsmanship guarantee and 3 years of free maintenance, all backed by NATE-certified technicians.

When Should You Replace Your R-410A System?

The refrigerant transition creates a clear decision framework for Greeley homeowners. 

Consider replacement if:

• Your unit is 10 years or older. AC systems typically last 15 to 20 years, but efficiency declines well before that mark.
• You’ve recharged R-410A more than once in the past three years, at $300 to $600+ per visit; those costs compound quickly.
• Repair quotes exceed 50% of your system’s value. That’s money spent on a depreciating asset with a shrinking support network.
• Energy bills are climbing without explanation. A new high-efficiency A2L unit can cut cooling costs by 30 to 50%.

Aging 12-to-15-year-old AC units near UNC and west Greeley are hitting their expiration dates just as the R-410A phase out spikes repair costs.

Key Takeaways

• The R-410A phase out is already in effect: Equipment production was banned January 1, 2025, under the AIM Act.
• Servicing existing units is still legal in 2026, but R-410A refrigerant prices are up 30 to 50% since the ban.
• R-454B is the primary replacement refrigerant, with a GWP of 466, 78% lower than R-410A.
• New A2L systems require purpose-built hardware; retrofitting an existing R-410A system is not possible.
• Units 10 years or older face escalating service costs that make replacement the smarter long-term investment.
• McCormick Heating & Cooling serves Greeley and the Front Range with NATE-certified technicians and free installation estimates.

Don’t Let the Phase-Out Catch You Flat-Footed This Summer

The R-410A phase out is already hitting Greeley homeowners where it hurts, in refrigerant prices, parts availability, and the true cost of keeping an aging system alive. 

Those who plan now, rather than waiting for an August breakdown, will have more options, shorter timelines, and more control over their budget.

McCormick Heating & Cooling has served Greeley and Weld County for over 19 years. 

Their NATE-certified technicians will help you decide whether continued repairs or a new A2L installation makes more financial sense before peak season hits.

FAQs About the R-410A Phase Out

1. What year will R-410A be phased out?

Under the AIM Act, the EPA banned the manufacture and import of new R-410A equipment as of January 2025.

While existing refrigerant stockpiles remain available for servicing older units, shrinking supplies will drive up recharge costs through 2027.

Homeowners don’t need to replace working systems immediately, but planning ahead avoids major cost surprises as regulatory windows tighten.

2. How long will R-410A be available in the USA?

Servicing R-410A systems remains completely legal, but strict EPA production caps mean supplies must now rely on shrinking stockpiles and reclaimed gas.

Consequently, dwindling volume is driving up prices while technicians naturally pivot to newer, compliant equipment.

For Greeley homeowners with aging systems, the window for cost-effective repairs is closing much faster than the legal timeline.

3. Will my existing R-410A AC still work?

No federal regulation forces you to replace a working R-410A air conditioner, and technicians can still legally service your system.

However, shrinking supplies have driven refrigerant recharge costs up 30–50% since the 2025 production ban, with further hikes expected.

For units over a decade old, a NATE-certified technician can run the numbers to see if upgrading makes better financial sense.
