Refrigerant Phase-Outs and What They Mean for Your AC System

Refrigerant may be invisible, but the impact it has on your home comfort—and the environment—is crystal clear.

Minnesota homeowners continue to upgrade ACs and heat pumps, a new question is popping up:

What’s going on with refrigerants, and how will it affect my system?
Let’s break it down.

What Is Refrigerant—and Why Is It Changing?
Refrigerant is the chemical inside your AC or heat pump that makes cooling possible. It absorbs indoor heat and dumps it outside—keeping your home comfortable.

Older refrigerants like R-22 (Freon) were phased out due to environmental harm. The current go-to, R-410A, is now on the chopping block too, thanks to its high global warming potential (GWP).

Key Dates Minnesota Homeowners Should Know

• 2020: R-22 banned for production/import in the U.S.
• 2025: R-410A starts phasing out under the AIM Act
• 2036 goal: 85% national reduction in HFCs like R-410A

If your system still uses R-22, it’s well past time to upgrade. If you’re on R-410A, your next replacement may use something even better.

What Are the New Refrigerants?
The HVAC industry is moving toward low-GWP refrigerants that are kinder to the environment and still highly efficient. Leading options include:

• R-32: Already popular globally; more efficient and lower GWP than R-410A
• R-454B: A rising star in U.S. systems; expected to be the primary R-410A replacement
• CO₂-based systems and other naturals: Gaining traction in niche high-efficiency markets

These refrigerants are safer for the planet and keep your home just as cool.

What Does This Mean for My AC or Heat Pump?If your system uses R-410A and is working fine, you’re okay for now—but it’s smart to plan ahead. Here’s what to keep in mind:

• Older units = harder to service. Prices for phased-out refrigerants spike as supply drops.
• Repairs may cost more. A leak in an R-410A system a few years from now could mean replacing the whole unit.
• New installs will use new refrigerants. Starting in 2025, most new systems will transition to R-32 or R-454B.

How to Prepare as a Minnesota Homeowner

• Schedule a pre-season checkup to assess your refrigerant and system status
• Talk to your HVAC provider about upgrade timelines and rebate options
• Plan for your next system with eco-friendly refrigerants in mind

The Bottom Line

Refrigerant phase-outs might sound technical, but they’re really about protecting your home comfort and the planet. Planning ahead ensures you avoid future repair surprises, stay compliant with regulations, and cool your home responsibly.
