📣 HVAC Need-To-Know: Refrigerant Phase Out

Ok this is one of those topics that you may not ever cross your desk — at least until your next HVAC servicing visit (and while we’re on the topic, this is your friendly reminder to book your annual HVAC maintenance appointment — summer’s around the corner!).

There is a global refrigerant phase-out effort being made to reduce substances that harm the ozone layer and contribute to climate change. Here’s what’s happening, in a nutshell, and what it could mean for your HVAC system:

What’s (exactly) Happening?

• Older refrigerants like R-22 (Freon) have been phased out because they deplete the ozone layer.
• Newer refrigerants like R-410A, which don’t harm the ozone, are also now being phased down because they have high global warming potential (GWP).
• The U.S. EPA, under the AIM Act, is reducing the use of HFCs (hydrofluorocarbons) like R-410A over the next 15 years.
• The next generation of refrigerants includes low-GWP options like R-32, R-454B, and R-1234yf.

What This Means for Your HVAC System:

• If your system uses R-22: It’s already banned, and servicing it is expensive because the refrigerant is only available through recovered or recycled supplies.
• If your system uses R-410A: You’re still okay for now. It’s widely available, and systems using it will still be supported for years—but prices may rise over time.
• New systems (starting around 2025): Will likely use R-32 or R-454B, which are more environmentally friendly but mildly flammable, requiring updates to building codes and technician training.

What You Should Do

• If your system is over 10-15 years old and uses R-22: Start budgeting for a replacement.
• If your system uses R-410A and is working fine: No urgent action is needed. Keep it maintained.
• If you’re replacing a system soon: Ask about systems compatible with new refrigerants. Some models available in 2025 and beyond will be designed for the new standards.

  How To: Determine What Refrigerant Your System Uses

• Look for a label or data plate on the outdoor condenser unit (the big box outside your house). It should say something like:
  • R-22 (older systems, typically installed before 2010)
  • R-410A (systems from 2010 to around 2024)
  • R-32 or R-454B (new systems starting around 2025)

• If you can’t find the label, you can also:
  • Check your owner’s manual
  • Look up the model number online
  • Ask your HVAC technician

•  Assess the Age and Condition of Your System

  • 0–10 years old: Likely uses R-410A and doesn’t need replacement unless failing.
  • 11–15 years old: Plan for a replacement soon — efficiency drops and repair costs rise.
  • 15+ years old: Near end-of-life. Replacement is strongly recommended, especially if it uses R-22.
