There's one line on your AC's data plate that quietly decides how expensive every future repair will be: the refrigerant type. Here's what each one means in 2026.
R-22: the expensive legacy
If your system predates roughly 2010, it likely runs R-22 (often labeled HCFC-22 or Freon). Production and import ended in 2020 — every pound used today is reclaimed or stockpiled, priced accordingly. A leak repair plus recharge that's routine on a modern system becomes a serious bill on R-22, and it lands on equipment that's already 15+ years old. That combination is why the repair-or-replace math so often says replace.
R-410A: the current standard
Most systems installed 2010–2024 run R-410A (Puron). Refrigerant is affordable and every tech stocks it. Repairs on these systems are usually worth making well past the 10-year mark.
R-32 and R-454B: the new generation
New equipment is shifting to lower-GWP refrigerants. If you're buying a system in 2026, you're likely buying one of these — nothing to worry about, just a different service ecosystem as it matures.
Which one do you have?
It's printed on the nameplate — outdoor unit, side or rear panel. Can't read the faded label, or don't want to decode the whole plate yourself? Snap a photo with our free Nameplate Decoder: it returns the refrigerant, the model, and the unit's age in one shot — the three facts that decide every repair conversation.
