What's the Difference Between Stay Cool, Stay Frosty, and It's A Frosty Life?
Stay Cool is Goodman 15 SEER2 single-stage at $8K-$14K (1-yr labor warranty), Stay Frosty is Carrier 18 SEER2 two-stage at $12K-$18K (2-yr labor, ductwork sealing included), It's A Frosty Life is Trane 20+ SEER2 variable-speed at $16K-$20K+ (5-yr labor warranty). Real specs, real prices, no marketing fluff.
I (Omar Jacobo, license TACLA126718E) built this comparison the way I'd explain it to a neighbor. SEER2 ratings reference the DOE central-AC efficiency program, and every tier's refrigerant is R-454B per the EPA AIM Act. When my own father-in-law replaced his system last year, he picked Stay Frosty — that's the math most Texas families end up at.

How Do I Decide Which Tier Fits My Home?
Decide by use case: pick Stay Cool ($8K-$14K) if you're replacing a dead system on a budget, Stay Frosty ($12K-$18K) if you want the best value for comfort plus efficiency (most buyers), and It's A Frosty Life ($16K-$20K+) for luxury homes 3,000+ sq ft or maximum efficiency with a 5-year labor warranty. All three use R-454B refrigerant and ship with Frosty's 10-year installation workmanship guarantee.

What Do Buyers Ask When Comparing Tiers?
When comparing Frosty's three tiers, buyers ask three questions most: which saves the most over 10 years (It's A Frosty Life for $300+/month summer cooling bills, Stay Frosty for everyone else), what the simplest comparison is (Stay Cool = cheapest, Stay Frosty = best value, It's A Frosty Life = best comfort), and where to see detailed equipment specs (each tier's own page has full AHRI model numbers and warranty terms).
