Why these are separate
Every comparison on this site is meant to answer "which one should I buy?" A discontinued lineup can't be the answer to that, and when it sits in the same side-by-side as a live one it quietly wins on the things it no longer has to compete on - an old list price, a tier the current lineup dropped. So legacy lines are left out of the comparisons and the equivalents on each product page, and live here instead.
They are still listed because stores still sell the remaining stock, people own them and need parts, and "what replaced it" is a real question. Most are R-410A systems: new installations of high-GWP refrigerants are being phased out under EPA rules, so check what your installer can still fit. Each product page below lists what you could buy instead today.
Prices on these pages are the last ones recorded, not current offers.
