Why AllenHomeowners Choose Frosty's for AC Replacement

Allen replacement jobs are unusually consistent. The city built out almost entirely between the late 1990s and the mid-2010s — Twin Creeks late-90s, Star Creek 2000s, Watters Creek 2010s — which means we're almost always pulling a 15-25 year old original system out of a 2,200-3,800 sqft two-story home. Most of these homes were built with a 4-ton or 5-ton system that was right-sized at the time, but with the original ductwork now 20+ years old and leaking 20-30% in the attic, a smaller variable-speed system often delivers better comfort with less capacity. Manual J load calculation gets done on every Allen replacement — no rules of thumb, no oversizing.

The duct conversation matters more in Allen than most cities because the attic-mounted air handlers run hot — 140-160°F summer attics — and the original R-4 flex duct from 1998-2010 is now brittle, sagging at the supports, and shedding insulation. On Stay Frosty (Carrier 18 SEER2 dual-stage) and It's A Frosty Life (Trane 20+ SEER2 variable speed) jobs, we include duct sealing on up to 5 connections, and on most Allen replacements I recommend at least a partial duct repair to capture the efficiency the new equipment is rated for. Dropping a 20 SEER2 variable-speed condenser onto leaky 20-year-old ductwork wastes most of the upgrade.

Every Allen 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 by tier: 1-year on Stay Cool (Goodman), 2-year on Stay Frosty (Carrier), 5-year on It's A Frosty Life (Trane). The 10-year extended labor warranty is +$3,500 across all tiers. Heat pump adds $2,000. Financing through Optimus, Synchrony, and GreenSky — $0 down on approved credit. 50% deposit at booking, balance on completion.
