What's a single-stage compressor?

Single-stage means the compressor runs at 100% capacity whenever it's on. It cycles on/off to maintain temperature. Less efficient than two-stage or variable-speed, but cheaper upfront and very reliable mechanically — fewer moving parts means fewer failure modes.

How much will I save vs. my current system?

If you're replacing a 10+ year-old system rated 13 SEER or lower, expect 15-25% savings on your cooling-season utility bill. The Stay Cool tier pays back its premium over a window unit / DIY route quickly because it's properly sized and professionally installed.

Can I upgrade to Stay Frosty or It's A Frosty Life later?

Not really — the equipment is sized for your home and there's no 'upgrade kit.' If you think you might want higher efficiency in the future, it's almost always cheaper to buy the higher tier today than to replace a Stay Cool system 5 years from now.

Does Stay Cool include a furnace?

Optional. The base price is for AC + air handler. Adding a matching gas furnace adds $1,800-$3,200. We'll show you both options on your price page so you can compare.

Why Did We Build the Stay Cool Tier?

We built the Stay Cool tier as Frosty's $8,000-$14,000 entry-level AC replacement for Texas homeowners who need a reliable new system without paying for premium efficiency features — a Goodman 15 SEER2 single-stage system installed all-in with a 1-year labor warranty, R-454B refrigerant, and permit handling. It's designed for budget-conscious replacements of 10-15 year-old failed systems where the math doesn't justify a high-SEER upgrade.

I (Omar Jacobo) personally picked Goodman 15 SEER2 because it's the sweet spot for value: meets current U.S. Department of Energy efficiency minimums published at energy.gov, uses the EPA AIM Act-compliant R-454B refrigerant, and Goodman parts are stocked at every supply house in Texas. If something needs service in year 8, your local tech — any tech, not just ours — can fix it the same day.

Most Stay Cool buyers are replacing a 10-15 year-old system that died, can't afford or don't want to finance a $15K+ replacement, and want a professional install they can trust. I installed one of these in my own father-in-law's Farmers Branch home last spring — it's honest entry-level, not 'builder grade,' but appropriately priced for what it is. Our TDLR license TACLA126718E (verifiable at tdlr.texas.gov/verify.htm) covers every Stay Cool install statewide.

Stay Cool Questions

What Do Buyers Ask About Stay Cool?

Stay Cool buyers ask five questions most: why Goodman (owned by Daikin, best parts availability at the entry price), what single-stage means (runs 100% capacity when on — cheaper and mechanically simpler), how much they'll save vs. their 10+ year-old system (15-25% on cooling bills), whether they can upgrade later (almost always cheaper to buy higher tier today), and whether a furnace is included (optional add-on, $1,800-$3,200 extra).

Goodman is owned by Daikin (the world's largest HVAC manufacturer) and offers the best parts availability and warranty value at the entry price point. Their 15 SEER2 single-stage equipment is genuinely reliable — not a 'cheap' brand, just a value-priced one.
