McKinney is a 35-minute run from our Farmers Branch shop up US-75. Same-day response is routine across all four ZIPs. We stock R-22 reclaimed for the Stonebridge Ranch / Eldorado Pkwy aging-equipment book, ECM blower modules and zoning control boards for the Craig Ranch and Adriatica mid-life variable-speed equipment, plus standard tune-up parts for the Trinity Falls newer-build maintenance work.
McKinney climate and installation context
McKinney grew from 55,000 to over 210,000 in two decades. Stonebridge Ranch (1988-2005) and the Eldorado Pkwy corridor are packed with 3-3.5 ton R-22 systems on their second or third capacitor cycle. Craig Ranch (2000-2015) and Adriatica's Mediterranean village show variable-speed ECM blower board failures, zoning damper actuators stuck mid-travel, and TXV starvation on upstairs coils in 3,500+ sqft two-stories. Trinity Falls (2018+) is mostly R-410A or R-454B equipment still under manufacturer warranty.

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 McKinney Homeowners Choose Frosty's for AC Replacement?
McKinney replacement jobs fall into three distinct buckets, and pricing each one honestly is what separates us from franchise operations that push the same 3-ton system on every home. The first bucket is Historic Downtown McKinney — pre-1950 pier-and-beam housing around the square on Tucker, Howell, and Anthony streets. Those homes were never designed for central HVAC, so retrofits involve relocating the air handler, rerouting line sets through crawlspace or attic, and often replacing ductwork that was jury-rigged in the 1980s. A Manual J load calculation (the ACCA standard per Energy.gov) is non-negotiable here because the original installer almost certainly oversized the system — dropping a 4-ton condenser onto a house that needs 2.5 tons is the number-one mistake I see in Historic Downtown, and it causes humidity problems, short cycling, and premature compressor death.
The second bucket is Stonebridge Ranch (1988–2005) and the Eldorado Pkwy corridor. These 20–35 year old master-planned homes are well past original equipment life, and most second-generation R-22 systems are aging into replacement territory. Long duct runs across large lots push ECM blower assemblies past their failure window. Stonebridge customers most often land on Stay Frosty (Carrier 18 SEER2 dual-stage, $12,000–$18,000) because the dual-stage operation matches two-story comfort needs without the cost jump to variable-speed. The third bucket is Craig Ranch (2000–2015), Tucker Hill, Adriatica, and Trinity Falls — newer high-end builds where owners are already accustomed to variable-speed comfort and almost always upgrade to It's A Frosty Life (Trane 20+ SEER2, $16,000–$20,000+). ENERGY STAR certified heat pumps in this tier qualify for up to $2,000 in federal tax credits under the Inflation Reduction Act (IRS Form 5695 at IRS.gov).
Every McKinney 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), City of McKinney mechanical permit and inspection, and full cleanup with haul-away. Labor warranty scales with the tier: 1-year Stay Cool, 2-year Stay Frosty, 5-year It's A Frosty Life. Financing through Optimus, Synchrony, and GreenSky — $0 down on approved credit, 50% deposit at booking. Replacement estimates are always free.

What Do McKinney Homeowners Ask About AC Replacement?
How Much Does a New AC System Cost in McKinney, TX?
Full system replacement at Frosty's HVAC runs: 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+. Exact price depends on tonnage (1.5–5 ton), electric versus heat pump (+$2,000), and optional 10-year labor warranty (+$3,500). All-electric systems save $1,000. Estimates are always free — we run Manual J load calculations on every McKinney home before quoting.
What SEER Rating Should I Choose for My Stonebridge Ranch or Craig Ranch Home?
For Stonebridge Ranch and Craig Ranch two-stories with multi-zone systems, I recommend 18 SEER2 dual-stage (Stay Frosty) at minimum. McKinney's 200+ cooling days mean high annual runtime, so a 20+ SEER2 variable-speed system (It's A Frosty Life) typically pays back the upgrade cost in 5–7 years through lower Oncor electricity bills. According to EnergyStar.gov, upgrading from a 10 SEER system to 18 SEER2 can cut cooling costs by nearly half. The IRA federal tax credit (up to $2,000 for qualifying heat pumps) accelerates the payback further.
How Long Does AC Installation Take in McKinney?
Standard residential replacement is one full day (8–10 hours). Homes needing ductwork repairs, electrical panel upgrades, or multi-zone reconfiguration can take 2 days. Historic Downtown McKinney pier-and-beam retrofits sometimes stretch to 2–3 days because of crawlspace duct routing. We pull the City of McKinney permit before work starts, and the municipal inspector comes out within 2–3 weeks of completion. Every install closes with a commissioning test — superheat, subcool, and static pressure verified against manufacturer specs.
Should I Replace or Repair My Aging R-22 System in McKinney?
For most McKinney homes with R-22 systems (common in Stonebridge Ranch, Eldorado Pkwy, and Historic Downtown), replacement wins the 5-year cost comparison if the system has a major leak or compressor failure. R-22 hasn't been produced since 2020 (EPA.gov Clean Air Act phase-out) and costs $150–$200 per pound. I run both repair and replacement numbers side-by-side so you can compare honestly. New systems install with R-454B or R-32 only — the current AIM Act refrigerant standard.
Do You Offer Financing for AC Replacement in McKinney?
Yes — Optimus, Synchrony, and GreenSky with $0 down on approved credit. 50% deposit at booking, balance on completion. Monthly payments work out to roughly the system midpoint divided by 60. Most McKinney homeowners get approved same-day. Qualifying ENERGY STAR heat pump installations may also stack with the federal 25C tax credit — up to $2,000 per household per year (IRS Form 5695). Between financing and tax credits, the out-of-pocket impact is significantly less than the sticker price.
Should I Replace My Old R-22 AC System in Stonebridge Ranch and Craig Ranch?
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 Stonebridge Ranch and Craig Ranch 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 Stonebridge Ranch and Craig Ranch 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 Stonebridge Ranch and Craig Ranch 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.
