The Next AC Refrigerant Transition for North Chicago Area Homeowners

If you’ve owned a home in the Skokie area for over a decade, you likely remember the R-22 (Freon™) refrigerant phase-out. It turned simple AC repairs into massive financial headaches. Now, the HVAC industry is facing an even more significant shift.

Whether you live in Skokie, Evanston, Morton Grove, Lake Villa, and Glenview, there is a new technical term you need to know: R-454B.

This isn’t just a minor update; it’s a total redesign of how new air conditioners operate, affecting your future repair costs and your home comfort.

Why R-410A is Being Phased Down

For the last 15 years, R-410A (often called Puron®) has been the standard for Chicagoland homes. While it protected the ozone layer, it is a high-GWP (Global Warming Potential) gas.

Under the federal AIM Act, the U.S. government is mandating an 85% reduction in high-GWP refrigerants by 2036. This means the supply of R-410A is about to dry up fast.

The New Standard: R-454B

To meet these green standards, leading manufacturers (our partners like Rheem and Amana) are switching to R-454B.

Here is what Skokie homeowners are asking our technicians:

Top 5 Things Skokie Homeowners Must Understand

1. Existing Units: If your AC is running fine, don’t panic. R-410A units can still be serviced, but the “gas” itself is about to get much more expensive.
2. The 2025 Deadline: Starting in 2025, manufacturers will stop producing R-410A residential systems. After current local inventory is gone, every new install will be an R-454B system.
3. Rising Repair Costs: As supply drops, the price of R-410A will spike. If your 10-year-old unit gets a leak in three years, the cost to recharge it could be a significant portion of a new unit’s price.
4. No “Retrofitting”: You cannot put R-454B into an old unit. They operate at different pressures and use different oils. A switch to the new refrigerant requires a full system replacement.
5. Safety (A2L): R-454B is classified as “A2L” (slightly flammable). While that sounds intense, these systems include new sensors and safety shut-offs that make them incredibly safe for residential use.

Strategy for the North Shore Summer

With our short but intense cooling season, timing your replacement is everything.

• Scenario A: Your AC is 12+ Years Old

  If your unit is struggling to keep up with July humidity, we recommend moving to an R-454B system now. By choosing the new technology today, you future-proof your home against the skyrocketing costs of old refrigerant.

• Scenario B: Your AC is Relatively New

  Keep up with your annual maintenance! The best way to save money is to ensure your current R-410A system doesn’t develop a leak. Small leaks that used to be a “cheap fix” will soon become very expensive.
