Real stories from recent Frosty's HVAC jobs in McKinney, TX -- published straight from the field.
Over on Eddington Dr in McKinney, a clogged AC drain line had the overflow pan filling up and water dripping outside the home. Our tech flushed both the primary and secondary drain lines, and now the water is flowing exactly like it should. One happy family, cool and worry-free a...
Over on Tangle Ridge Dr in McKinney, a family was struggling with a system that just wasn't cooling. Our tech tracked it down to an airflow restriction from a dirty filter, swapped out the filter, and gave the whole system a thorough once-over — inspecting the condenser and evapo...
When our tech arrived on Jace Dr in McKinney, this family's system had stopped cooling because it was low on refrigerant. To keep them comfortable without stretching the budget, they chose to have us add a leak-seal treatment and recharge the unit back to spec — an honest, tempor...
Our team services McKinney from our Farmers Branch base — 28 miles via US-75 North, roughly 35 minutes. We cover 75069, 75070, 75071, and 75072 including Stonebridge Ranch, Craig Ranch, Trinity Falls, Adriatica, Tucker Hill, and Eldorado Pkwy corridor. McKinney sits in Collin County.
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 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.
AC repair in McKinney starts at $85 for the diagnostic (waived with any repair). Most common repairs fall in the $350-$1,500 range — we're flat rate, which means the price we quote before we start is the price you pay at the end. Frosty Club members save 10-15% on every repair.

Join Frosty ClubIn my 8 years servicing McKinney homes, 80% of the emergency repair calls I get come down to a handful of issues. Here's what I see most often — and what each one typically costs to fix.
Usually a failed capacitor ($500), contactor ($600), or a tripped float switch. Diagnostic identifies the exact cause.
Low refrigerant from a leak, failed compressor, or iced-over evaporator coil. We find and fix leaks — we never gas-and-go.
Restricted airflow or low refrigerant. Shut the system off and call us before it destroys the compressor.
Clogged drain line ($350) or damaged drain pan ($1,200). A $400 float switch prevents future water damage.
Worn blower motor bearings, loose fan blade, or failing compressor. Don't ignore it — small noises become big repairs fast.
Weak capacitor, oversized system, failing thermostat, or refrigerant problem. Short cycling kills compressors in under a year.
McKinney is a 35-minute run from our Farmers Branch shop up US-75, and AC repair calls here split cleanly by housing generation across a city that grew from 55,000 to over 210,000 in two decades. Stonebridge Ranch (1988–2005) and the Eldorado Pkwy corridor are packed with 3-ton and 3.5-ton R-22 systems on their second or third capacitor cycle — 80% of those calls are capacitor failures ($500 flat, $425 Frosty Club), contactors ($600 / $510), and single-speed blower motors that finally burned through their start windings after 25 North Texas summers. Craig Ranch (2000–2015) and Adriatica's Mediterranean-style village show a different failure pattern: variable-speed ECM blower boards losing commutation, zoning damper actuators stuck mid-travel, and TXV starvation on upstairs coils in 3,500+ sqft two-stories where the second floor sits 8–12°F hotter than the great room. Trinity Falls — McKinney's newest large master-planned community on the north side — is mostly 2018-and-newer builds with R-410A or R-454B equipment still under manufacturer warranty, where tune-up neglect and builder-grade component quality are the early failure drivers.
McKinney has more corporate-campus remote workers than almost anywhere in Collin County — Toyota North America at Legacy (just south in Plano), Raytheon, Globe Life, and the growing medical corridor along US-380 all push daytime home occupancy higher than the DFW average. That matters because your compressor logs 14–16 hours a day instead of the 6–8 a typical commuter household puts on it, and I've pulled dead compressors out of Craig Ranch and Stonebridge homes at year 8 that should have lasted 12–15. According to the U.S. Department of Energy (Energy.gov), proper HVAC maintenance can reduce energy consumption by 15–25% — in McKinney's 200+ cooling-day climate with Oncor-delivered electricity averaging 13.8¢/kWh, that's $300–$600 in annual savings on a system running correctly versus one limping along with a weak capacitor or low charge. Twice-yearly maintenance and smart thermostat setbacks during peak ERCOT hours matter more here than most homeowners realize.

Deeper context on ac repair written by Omar Jacobo (EPA 608 #2396328).
AC repair in McKinney typically costs $350–$1,500 at Frosty's HVAC, with our $85 diagnostic fee waived when you approve the repair. Specific flat-rate prices: capacitor $500 ($425 Frosty Club members), contactor $600 ($510), standard blower motor $750–$1,500 ($637.50–$1,275), ECM variable-speed blower up to $2,800, refrigerant leak find-fix-recharge $350–$1,000, compressor $3,500–$5,000. Frosty Club Premium members save 15% on every repair plus a $500 credit — membership pays for itself on a single major repair. We never quote hourly and we never add surprise mid-job charges.
In Craig Ranch, Stonebridge Ranch, and Trinity Falls two-stories, the upstairs-too-hot complaint almost always traces to one of three issues: a TXV losing charge on the upstairs evaporator coil, a zoning damper actuator stuck partially closed, or an ECM blower drifting out of factory spec because the control module aged out. Our $85 diagnostic isolates which one. Adding a smart thermostat, installing more zoning, or topping off refrigerant without a leak search won't fix an airflow or metering problem — I've seen McKinney homeowners burn $1,500 on band-aids before calling us for the actual diagnosis.
Start with three questions: Are they licensed by TDLR (Texas Department of Licensing and Regulation)? Do they quote flat-rate or hourly? Will the actual technician — not a sales rep — diagnose your system? Frosty's HVAC holds Texas contractor license TACLA126718E, I'm EPA 608 Universal certified (#2396328), and we quote every job flat-rate from a published pricing book. 143 Google reviews at 4.9 stars, family-owned since 2018, and we answer the phone directly — no call center. Ask any McKinney HVAC company these questions and compare their answers to ours.
Yes — EPA 608 Universal certification means I can legally recover, recycle, and recharge R-22 refrigerant under federal regulations. R-22 production ended in 2020 under the Clean Air Act phase-out (EPA.gov), so reclaimed stock now runs $150–$200 per pound. For a 1990s Stonebridge Ranch or Eldorado Pkwy system with a major leak or compressor failure, I quote both repair and full replacement side-by-side so you can make an informed decision. New installs use R-454B or R-32 only — the current AIM Act refrigerant standards. ENERGY STAR certified heat pumps may qualify for up to $2,000 in federal tax credits under the Inflation Reduction Act (IRS Form 5695).
Short cycling narrows to three suspects: a frozen evaporator coil (restricted airflow from a clogged filter, failing blower, or untreated refrigerant leak), a weak capacitor that can't hold the compressor in a stable amp draw, or an oversized system that drops the thermostat setpoint too fast and shuts off before dehumidifying. In McKinney I see all three — the oversized-system problem especially in 1980s–90s homes where a contractor bolted a 4-ton condenser onto a 2.5-ton Manual J load without doing the calculation. The $85 diagnostic identifies which cause, and we fix flat-rate. Frosty Club Basic ($99/yr) saves 10% on every repair; Premium ($300/yr) saves 15% plus a $500 credit.
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.
Yes, I can repair it — R-410A production for new equipment ended Jan 2025 under the AIM Act (Energy.gov), but EPA 608 Universal cert #2396328 covers ongoing service. R-410A recharge runs $100 per pound installed. A typical Stonebridge Ranch and Craig Ranch leak repair totals $450-$700: electronic leak detection ($250) or nitrogen leak test ($500) plus recharge at $100/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, replacement to R-454B or R-32 is usually the better economics. Read our R-410A phase-out explainer.
