Southlake is about 40 minutes west via SH-114. Same-day calls Monday-Friday are routine.

We don't run commission-driven upsell — flat-rate every time.
Southlake climate and installation context
Southlake housing stock is overwhelmingly 1990s-2010s — Carillon, Timarron, Shady Oaks, the larger estate-lot builds north and south of Town Square — 4,000-7,000+ sqft homes with 3-4 zone systems, variable-speed ECM blowers, dual-fuel setups, and smart thermostats. Original R-22 systems are essentially extinct here because most of these homes were built after R-22 was already on the regulatory clock. ECM blower drift, zoning damper failures, and TXV issues are the top three Southlake repair calls.

Every tier — Stay Cool, Stay Frosty, It's A Frosty Life — includes the same baseline package. No bait-and-switch, no surprise add-ons at install. Here's exactly what you get.
Why Do Southlake Homeowners Choose Frosty's for AC Replacement?
Southlake replacement jobs are almost never single-system swaps. The typical 76092 home is 4,000-7,000+ square feet with 3 or 4 zones, which means 2 or 3 separate condensers and air handlers feeding multiple zoning panels. When one system fails after 12-15 years, the others are usually right behind it — same install date, same duty cycle, same wear pattern. We do a lot of staged replacements here: replace the worst-performing system this year, the next one in 18 months, the third one when it finally goes. Manual J load calculation per zone is mandatory because Southlake homes have weird heat loads — 2-story foyers, west-facing window walls, media rooms with no airflow, attic master suites that bake all afternoon.
Almost every Southlake replacement we quote lands on Stay Frosty (Carrier 18 SEER2 dual-stage) or It's A Frosty Life (Trane 20+ SEER2 variable speed). The reason is duty cycle plus zoning. A variable-speed system running at 35-50% capacity for 14 hours uses dramatically less electricity than a single-stage running full blast for 5 hours, and on a multi-zone home the comfort difference is night-and-day — no more cold blasts followed by silence followed by cold blasts. For Carillon, Timarron, and Shady Oaks customers with high-end finishes and demanding comfort expectations, It's A Frosty Life (Trane variable speed) is what we install most often. Stay Cool (Goodman) goes in for budget-conscious replacements or rental properties — it's still a great system, just not the tier most Southlake owners pick.
Every replacement includes a Frosty Thermostat (our smart WiFi thermostat), 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. Heat pump or dual-fuel setups (common in Southlake) add $2,000 over the base tier. Financing through Optimus, Synchrony, and GreenSky — $0 down on approved credit. Flat-rate pricing is unusual in this market, and Southlake homeowners tell us regularly it's a relief not to be commission-pitched.

What Do Southlake Homeowners Ask About AC Replacement?
How much does a new AC system cost in Southlake, TX?
Flat-rate 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-$20,000+. Most Southlake homes need 2 or 3 systems replaced over time given the 4,000-7,000+ sqft footprint and zoning. Heat pump adds $2,000; 10-year labor warranty adds $3,500.
What SEER rating do you recommend for Carillon, Timarron, and Shady Oaks homes?
For most Southlake estate homes with multi-zone systems and variable-speed expectations, It's A Frosty Life (Trane 20+ SEER2 variable speed) is what we install most often. The duty cycle on a 4,000-7,000 sqft home with multiple occupants and high comfort standards justifies the upgrade — utility bill savings typically pay back the tier difference in 5-7 years through Oncor.
How long does AC installation take in Southlake?
Single-system replacement is one full day (8-10 hours). On Southlake 3-4 zone homes where we're replacing 2 or 3 systems together, plan on 2-3 days. We pull the Southlake permit before we start and the city inspector comes out within 2-3 weeks of completion. We schedule around your work-from-home or travel calendar.
Should I replace all my zone systems at once or stage them?
Depends on age and condition. If all 3 systems were installed the same year and are 12-15 years old, doing them together saves on labor and gets you matched equipment under one warranty. If one system is failing and the others are still solid, we stage the replacements — replace the worst this year, next system in 18 months. We give you the honest tradeoff with both numbers, no pressure either way.
Do you offer financing for AC replacement in Southlake?
Yes — Optimus, Synchrony, and GreenSky with $0 down on approved credit. 50% deposit at booking, balance on completion. Even on $30,000-$50,000 multi-system replacements, monthly payments work out to roughly 1/60th of the total. Application takes 5 minutes and most Southlake homeowners get approved same-day.
Should I Replace My Old R-22 AC System in Southlake Town Square and Carillon?
Yes — EPA 608 Universal cert #2396328 lets me legally recover, recycle, and recharge R-22 under federal regulations. R-22 production ended in 2020 under the Clean Air Act phase-out (EPA.gov), so it now runs $200 per pound installed. A typical Southlake Town Square and Carillon R-22 leak repair totals $650-$1,000: electronic leak detection ($250) or nitrogen leak test ($500) plus recharge at $200/lb. Optional leak seal $350 — but it can void manufacturer warranties, so I only recommend it in specific cases. For systems past 12 years with major leaks, planning the transition to R-454B or R-32 is usually the better economics. Read our R-410A phase-out explainer for DFW homeowners.
Do I Need to Replace My R-410A System in Southlake Town Square and Carillon Because of the AIM Act?
No — not just because of the AIM Act. R-410A production for new equipment ended Jan 1, 2025 under the AIM Act (Energy.gov), but existing systems remain serviceable indefinitely under EPA 608 Universal cert #2396328. I'd only recommend replacing a Southlake Town Square and Carillon R-410A system if it's past 12-15 years old, has compressor failure, or has a major leak that makes ongoing recharges (R-410A at $100/lb installed, plus $250-$500 leak detection) uneconomical. New replacements use R-454B or R-32 only. Read our R-410A phase-out explainer for DFW homeowners.
