Emergency HVAC in McKinney, TX
No cool on a 105°F day. No heat on a 25°F night. Gas smell at 2 AM. When HVAC fails, you need flat-rate, honest, fast response. $85 diagnostic, $250 after-hours, $0 overtime for Frosty Club members. Licensed TACLA126718E, EPA 608 Universal certified, family-owned since 2018.
Gas Smell or CO Alarm? Call 911 + Atmos Energy FIRST
Gas smell: Leave the house immediately. Do not flip switches or light matches. From outside, call Atmos Energy: 866-322-8667. Atmos will shut off the gas at the meter. CO alarm sounding: Leave immediately and call 911 from outside. Once safety services have cleared the house, call us at (469) 254-0548 for diagnostic and repair. We NEVER repair cracked heat exchangers — those require full furnace replacement only.
Where in McKinney Do We Run Emergency Calls?
Emergency response to McKinney runs 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.
Now serving McKinney
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 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.

Join Frosty ClubWhat Counts as an HVAC Emergency in McKinney?
Some HVAC problems can wait until tomorrow. Others can't. Here's how I triage emergency calls in McKinney — and what to do in each case.
No cooling, 95°F+ summer
Real emergency when elderly, infants, or anyone with medical conditions is in the house. DFW summer heat kills. Move family to coolest room, run fans, stay hydrated, call us immediately.
No heat, below 35°F
Emergency for elderly, infants, and pipe-freeze risk. Usually ignitor, flame sensor, gas valve, or pressure switch. $400-$1,200 range. Same-visit fix when parts are in stock.
Gas smell
LIFE SAFETY. Leave the house immediately, call Atmos Energy 866-322-8667 from outside, then 911. Do not flip switches. Once gas is shut off, call us to diagnose the source and repair.
CO alarm sounding
LIFE SAFETY. Leave the house, call 911 from outside. Usually a cracked heat exchanger (full furnace replacement, we NEVER repair) or vent leak (repairable). Never run the furnace until cleared.
Water leaking from air handler
Clogged condensate drain triggered the safety switch — or the pan overflowed and water is dripping from the ceiling. Shut off the breaker. Call us. Drain clearing runs $350 ($297.50 members).
Electrical burning smell
Shut off the breaker immediately. Usually a failing contactor, blower motor, or wire connection. Do NOT run the system until we diagnose. Repair is $500-$1,500 range.
Why Do McKinney Homeowners Call Frosty's for Emergencies?
McKinney emergency HVAC calls cluster in three predictable windows we've learned to staff for: the first 100°F+ streak of June when Stonebridge Ranch and Eldorado Pkwy capacitors fail simultaneously across entire streets, the first hard freeze of December when furnaces that were fine in April refuse to ignite on the coldest night of the year, and any thunderstorm that takes down Oncor power lines and sends a surge through the neighborhood on grid restoration. That surge pattern is uniquely destructive in McKinney's newer Craig Ranch and Trinity Falls subdivisions — variable-speed inverter boards and communicating thermostat modules are more voltage-sensitive than the old single-stage equipment in Stonebridge. We're 35 minutes up US-75 from our Farmers Branch shop, so same-day emergency dispatch is routine. Frosty Club Premium members get priority routing — typically inside one hour; non-members during business hours, 2–3 hours.
What actually warrants a same-day emergency call in McKinney: AC completely down and indoor temp above 95°F with children, seniors, or pets in the house; heat completely down and outdoor temp below freezing; condensate water dripping from the ceiling or through a light fixture (Stonebridge Ranch's most common July water-damage scenario); burning smell, visible smoke, or electrical ozone odor from any HVAC component; suspected natural gas leak (call Atmos Energy emergency line and 911 first, then us); or CO detector alarming within 10 feet of the furnace. Per EPA indoor air quality guidance (EPA.gov), carbon monoxide exposure above 35 ppm sustained requires immediate evacuation. If the house is stable and you're simply uncomfortable, scheduling a next-day visit at the regular $85 diagnostic rate saves money versus emergency dispatch.
Emergency diagnostic pricing is the same $85 flat as a scheduled visit, waived when you approve the repair — we never stack emergency surcharges on top of flat-rate pricing during business hours. After-hours rates (before 7 AM, after 8 PM): $250 non-member, $212.50 Frosty Club Basic, $85 for Frosty Club Premium (regular rate, no overtime). The repair price itself stays constant regardless of clock — a capacitor is $500 at 2 PM or 2 AM, a drain clear is $350 day or night.

Why Should I Trust Frosty's Credentials for Emergency HVAC?
Because every credential is independently verifiable and directly tied to the emergency — Texas HVAC Contractor License TACLA126718E regulates how we touch gas and electrical, EPA CO safety guidance governs every cracked-heat-exchanger call, and the U.S. Department of Energy documents why annual maintenance prevents the emergencies in the first place.

Texas HVAC Contractor License held by Mariafernanda Jacobo. Issued and regulated by the Texas Department of Licensing and Regulation.
EPA Combustion Safety
Per the U.S. EPA CO Safety Guide, cracked heat exchangers are a leading cause of residential CO poisoning. We NEVER repair — full replacement only.
DOE Emergency Preparedness

What Do McKinney Homeowners Ask About Emergency HVAC?
Do You Offer Emergency HVAC Service in McKinney After Hours?
Yes — we run after-hours emergency response year-round for McKinney, with overnight dispatch prioritized for no-heat below-freezing and no-AC above-95°F scenarios when vulnerable family members are home. After-hours diagnostic: $250 non-members, $212.50 Frosty Club Basic, $85 Frosty Club Premium (waived with repair). Repair prices stay flat-rate regardless of time. Call (469) 254-0548 — a real human answers, usually Omar or Mariafernanda directly.
What Counts as an HVAC Emergency in McKinney?
True emergencies: AC down above 95°F with kids, seniors, or pets in the house; heat down below freezing; water dripping from the ceiling with AC running (condensate overflow — Stonebridge Ranch's July specialty); burning or electrical smell; visible smoke from any component; suspected gas leak (call Atmos Energy first); CO detector alarm near the furnace. If the thermostat reads 78°F and you want 72°F, that's uncomfortable but not an emergency — next-day regular-rate service saves you the overtime tier.
How Fast Can You Reach McKinney for an HVAC Emergency?
35 minutes on US-75 from our Farmers Branch shop off-peak, 50 minutes during rush hour. Business-hour emergency response: typically inside one hour for Frosty Club Premium members (priority routing), 2–3 hours for non-members. After-hours dispatch usually within two hours of your call. These are real drive-time numbers from 11410 Mathis Ave — not a 'sometime between noon and six' answering-service estimate.
Do You Add Emergency Surcharges on Top of McKinney Repair Prices?
No. Flat-rate means flat-rate. Business-hour diagnostic is $85 (waived with repair) regardless of urgency. After-hours adds the overtime diagnostic tier ($250 / $212.50 Basic / $85 Premium), but the repair itself is identical — a capacitor is $500 whether it fails at 2 PM or 2 AM. Frosty Club Premium eliminates the after-hours surcharge entirely, which pays for the $300 annual membership on a single overnight call.
Water Is Dripping From My McKinney Ceiling — Is That an Emergency?
Yes — treat it as urgent. A clogged condensate drain line backing up into the overflow pan is the number-one HVAC water-damage cause in McKinney during July humidity spikes. Leave the AC running and drywall gets soaked, attic insulation wicks the water laterally, and mold can establish within 24–48 hours per EPA indoor moisture guidance (EPA.gov). Shut the AC off at the thermostat immediately and call (469) 254-0548. Drain line clear is $350 ($297.50 Frosty Club members), float-switch install is $400 ($340 members) — it auto-shuts the system before overflow happens next time.
Do You Handle Emergency R-22 AC Failures 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 You Handle Emergency R-410A AC Failures in Stonebridge Ranch and Craig Ranch?
Yes — EPA 608 Universal cert #2396328 covers R-410A diagnosis, leak detection, and recharge. AIM Act 2025 phase-out (Energy.gov) affects new equipment manufacturing, not service work. For a Stonebridge Ranch and Craig Ranch R-410A emergency, expect $250 electronic leak detection (or $500 nitrogen for complex leaks) plus recharge at $100/lb installed. Most repairs run same-day. Read our R-410A phase-out explainer for DFW homeowners.
