Should You Upgrade to an R-32 AC System Now or Wait? Tony Weighs In
If you're still running an R-410A system, you're not alone. Plenty of good equipment out there still runs just fine on it. But I’ve been getting this question more and more:
“Tony, should I swap it out now for one of those new R-32 systems, or wait until my old one dies?”
Short answer? It depends on your system’s age, performance, and how long you plan to stay in your home or manage your property. But let’s break it down like I would with a customer on-site.
The Clock Is Ticking on R-410A
First off, you’ve probably heard by now that R-410A is being phased down as part of the AIM Act, following international agreements like the Kigali Amendment to the Montreal Protocol. The goal? Reduce high-global-warming-potential refrigerants.
Here’s what that means for you:
-
R-410A production is already capped and being reduced yearly
-
Prices for R-410A are going up—fast
-
Parts and compatible components will become harder to find
So if you’re hanging on to a 10+ year old system that still runs R-410A, you’re going to feel the squeeze soon—especially if it needs a major repair or a recharge.
Why R-32 Is Taking Over
R-32 isn’t just another “green” refrigerant. It actually performs better, uses 30% less charge, and has a much lower GWP—around 675 compared to 2,088 for R-410A. That’s a 70% reduction in environmental impact, and it meets the latest efficiency standards like SEER2.

Who Should Upgrade Now?
Here’s who I tell to go ahead and make the jump:
1. Systems Over 10 Years Old
If your system is pushing a decade or more, it’s only a matter of time. Rather than sinking money into leak repairs, compressor replacements, or recharging with overpriced R-410A, you’re better off installing a new R-32 system.
2. Properties with Heavy Cooling Demand
Landlords, multi-unit owners, or folks in hot southern climates—this one’s for you. R-32 systems are more efficient and recover faster in extreme heat. You’ll save on your electric bill, and reduce the odds of mid-summer breakdowns.
3. Anyone Doing a Major Reno or Home Sale
If you’re remodeling or getting ready to sell, an upgraded R-32 system can be a selling point. Modern buyers like high-efficiency HVAC, and having a future-proof system makes the listing stronger. The U.S. Department of Energy lists HVAC upgrades among the top improvements for boosting resale value.
Who Might Wait?
There are still scenarios where it makes sense to hold off—for now.
1. Your System Is Under 7 Years Old
If you’ve got a high-efficiency R-410A unit that’s only a few years in, no need to rush. Just keep it well maintained. But I always recommend planning the transition early, so you’re not scrambling during a failure.
2. You’re on a Tight Budget
R-32 systems are competitively priced, but if cash is tight, you can ride out your current setup a bit longer. Just remember, waiting too long could cost more in refrigerant, parts, and lost efficiency.
Pro tip: Many state energy rebate programs are starting to reward upgrades to low-GWP systems. Check Energy Star’s rebate finder to see if you qualify.
Tony’s Bottom Line
Here’s the no-fluff advice I give friends and longtime customers:
-
If your system is older than 10 years, runs constantly, or needs R-410A servicing, it’s time to upgrade.
-
If your unit’s in great shape, under 7 years old, and doesn’t give you problems, you’ve got some runway—but start planning.
-
If you’re upgrading anyway, don’t waste money on old tech. Go with R-32 and SEER2-compliant gear now.
And if you’re shopping, make sure you’re looking at systems that use R-32 refrigerant, have matching air handlers, and come from a trusted manufacturer.
