Why DentonHomeowners Choose Frosty's for AC Replacement
Denton replacement jobs are the widest-ranging mix we quote anywhere in DFW. On the historic square and the streets around UNT — Wolflin, Oak Gardens, Mockingbird Lane — we're replacing systems in prewar homes from the 1900s-30s that were retrofit for central air decades after they were built. The original ductwork is undersized for anything modern, so a replacement there isn't just swapping the condenser on the pad — it's a Manual J load calculation, duct resizing at minimum, and often replacing the plenum entirely. Dropping a shiny new 4-ton system onto 1950s-era retrofit ductwork is the #1 reason I see DIY-adjacent replacements fail within 3 years in central Denton.
On the outskirts, rural Denton acreage homes are a different animal. Many are still running R-22 equipment from the 90s, and replacement there is almost always the right call over chasing leaks in a system that costs more to refill than fix. Robson Ranch — the 55+ master-planned community off FM 2449 — is the most predictable customer base we have in Denton. Those homes are 2000s+ construction, generally right-sized from day one, and the retirees living there run the thermostat 14+ hours a day. That duty cycle makes the Stay Frosty (Carrier 18 SEER2 dual-stage) or It's A Frosty Life (Trane 20+ SEER2 variable speed) tier an easy math problem — the Oncor savings pay back the tier upgrade in 5-7 years.
Every replacement includes a Frosty Thermostat (our smart WiFi thermostat — not Nuve), new disconnect box, electrical whip, overflow condensate shutoff, condensate drain treatment, copper line inspection (replaced if needed), permit, and full cleanup with haul-away. Labor warranty scales with the tier: 1-year on Stay Cool, 2-year on Stay Frosty, 5-year on It's A Frosty Life. All equipment comes with manufacturer warranty. Financing available through Optimus, Synchrony, and GreenSky — $0 down on approved credit.

AC Replacement FAQ for Denton, TX
How much does a new AC system cost in Denton, TX?
Flat-rate pricing by tier: Stay Cool (Goodman 15 SEER2 single-stage) $8,000-$14,000, Stay Frosty (Carrier 18 SEER2 dual-stage) $12,000-$18,000, It's A Frosty Life (Trane 20+ SEER2 variable speed) $16,000-$26,000. Exact price depends on tonnage and whether it's electric or heat pump. Heat pump adds $2,000; 10-year labor warranty adds $3,500.
What SEER rating do you recommend for Robson Ranch homes?
For Robson Ranch and similar 55+ master-planned communities, I recommend 18 SEER2 dual-stage (Stay Frosty) at minimum. Retirees home all day run the system 14+ hours, and a variable-speed 20+ SEER2 system (It's A Frosty Life) typically pays back the upgrade cost in 5-7 years through Oncor bill savings. The longer runtime also means quieter, more even cooling, which matters when you're home to notice it.
Should I replace the R-22 system in my rural Denton home?
For most rural Denton acreage homes still running R-22, yes. Production ended in 2020 and reclaimed R-22 now runs $150-$200/lb, so any meaningful leak or compressor failure tips the math toward replacement. We run the numbers both ways — repair vs. replace — and show you side-by-side costs. For older equipment on septic/well properties where access matters, we also make sure line sets and electrical can handle a modern system before we quote.
Can you replace the AC in my downtown Denton historic home without tearing up the walls?
Usually yes, but the honest answer depends on what your current ductwork looks like. On prewar homes around the square and Wolflin, the 1980s/90s retrofit ductwork is often undersized but still accessible from the attic. We can resize supply runs and upgrade returns without touching finished walls in most cases. A proper Manual D duct sizing calculation during our quote tells us exactly what the job needs.
