R-454B Is Replacing R-410A: What San Antonio Homeowners Should Know

By Manny Pozos · June 29, 2026 · 5 min read

If you've gotten a quote lately and heard the words "R-454B" or "new refrigerant," you're not being upsold — the whole industry is transitioning. Here's the honest, no-hype version.

What's actually changing

New systems are moving from R-410A to R-454B, a lower-global-warming-potential refrigerant. R-410A isn't banned overnight, but it's being phased down, which affects long-term availability and price.

What it means for your existing system

If your AC runs R-410A, keep it. You don't need to replace a working system. We can still service and repair R-410A equipment. The change mostly matters when you're replacing a system anyway.

Where we stand

We've trained our crew on R-454B handling and we're leading with it on new installs — so the system we put in today is built around the refrigerant of the future, not the past.
