Now serving Keller
Keller is about 35 minutes from our Farmers Branch shop via TX-114 west to TX-170. We try to batch Keller routes to keep response time tight, so book early when possible. We stock ECM blower modules, zoning control boards, and TXV kits for the Carrier Infinity / Trane XV communicating dual-zone systems common in Hidden Lakes, Marshall Ridge, Estancia, and the Oaks of Fossil Ridge.
Keller climate and installation context
Keller homes are predominantly 3,500-5,500 sqft custom two-stories on half-acre-plus lots built 1995-2015, almost all running dual-zone HVAC with two air handlers, two condensers, and zoning dampers. The half-acre-plus lots also mean longer refrigerant line sets — leaks have more places to hide, and TXV / ECM control-board faults on the upstairs zone are the dominant Keller failure mode rather than capacitor or contactor issues.

Why Do Keller Homeowners Choose Frosty's for AC Replacement?
Keller replacement jobs are bigger and more complex than almost any other DFW city we serve. Hidden Lakes, Marshall Ridge, The Oaks of Fossil Ridge, Bloomfield, and Estancia are built out with 3,500-5,500 sqft two-story custom homes on half-acre-plus lots, and most of them run dual-zone systems — meaning we're replacing TWO air handlers, TWO condensers, and re-commissioning the zoning controls and dampers as part of the job. That's why a Keller replacement can land anywhere from $16,000 for a single 3-ton base-tier system up to $26,000 on a dual-zone It's A Frosty Life (Trane, 20+ SEER2 variable speed) with 10-year labor warranty. We quote each zone separately so you can see exactly where the money goes.
The housing stock here is newer — mostly 1990s-2010s — so the ductwork is usually in better shape than what we see in older DFW cities, but the long line sets that come with half-acre lots add complexity. Line sets of 50-80 feet (vs the 25-foot average in Farmers Branch or Irving) mean more places for refrigerant leaks, more pressure drop to design around, and more copper to inspect during the replacement. We replace line sets if they show any corrosion or rubbed-through insulation, period. The KISD school district keeps families rooted in Keller for 10-20 years, so the long-term economics of choosing a variable-speed 20+ SEER2 system (lower Oncor bills over the life of the system) work especially well here.
Every Keller replacement includes a Frosty Thermostat per zone (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. All equipment comes with manufacturer warranty. Financing available through Optimus, Synchrony, and GreenSky — $0 down on approved credit. Keller is 35 minutes from our shop, so we schedule replacement installs carefully — usually one full day per zone on dual-zone jobs.

What Do Keller Homeowners Ask About AC Replacement?
How much does a new AC system cost in Keller, 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-$20,000+. Most Keller custom homes are dual-zone — that's two systems, so full-home replacement often lands $20,000-$26,000. Heat pump adds $2,000 per system; 10-year labor warranty adds $3,500.
What SEER rating do you recommend for Keller custom homes?
For 3,500-5,500 sqft Keller homes with dual-zone systems, I recommend 18 SEER2 dual-stage (Stay Frosty) at a minimum and 20+ SEER2 variable speed (It's A Frosty Life) for the highest return. Families who stay in Keller for 10-20 years (common thanks to KISD) recover the tier upgrade cost 2-3 times over through lower Oncor bills. Variable-speed equipment also runs quieter — noticeable in larger homes with open floor plans.
How long does AC installation take on a Keller dual-zone system?
Single-zone replacement is one full day (8-10 hours). Dual-zone Keller homes usually take 2 full days — one per system — because we re-commission the zoning controls, balance dampers, and verify airflow on each zone independently. Homes with line-set replacements or ductwork repairs can add a day. We pull the Keller permit before we start, and the city inspector comes out within 2-3 weeks of completion.
Do I have to replace both zones at the same time in my Keller home?
No. If one system is 18 years old and failing while the other is 8 years old and healthy, we'll replace just the failing one. But if both systems are the same age and one fails, I usually recommend replacing both at once — you save on the second permit, on a single mobilization to your home, and you get matched equipment efficiency. We quote both options side-by-side so you can decide.
Do you offer financing for AC replacement in Keller?
Yes — Optimus, Synchrony, and GreenSky with $0 down on approved credit. 50% deposit at booking, balance on completion. Monthly payments work out to roughly 1/60th of the system price — on a $22,000 dual-zone Stay Frosty job that's about $367/month. Applications take 5 minutes and most Keller homeowners get approved same-day. Call (469) 254-0548.
Should I Replace My Old R-22 AC System in Hidden Lakes and Marshall Ridge?
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 Hidden Lakes and Marshall Ridge 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 Hidden Lakes and Marshall Ridge 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 Hidden Lakes and Marshall Ridge 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.
