Real stories from recent Frosty's HVAC jobs in McKinney, TX -- published straight from the field.
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...
When our tech arrived at a home on Spanishmoss Dr in McKinney, the AC was blowing hot air and the lines on the condenser were frozen solid on a nearly 30-year-old R-22 system. We installed a new drain pan package and, to help this family stay cool within their budget, added R-22 ...
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.
Furnace repair in McKinney starts at $85 for the diagnostic (waived with any repair). Most common heating repairs fall in the $250-$1,300 range. We're flat-rate, which means the price quoted before we start is the price you pay at the end. Frosty Club members save 10-15% on every repair.

A cracked heat exchanger means combustion gases — including carbon monoxide — can leak into your home's air supply. We NEVER repair a cracked heat exchanger. The only safe fix is a full furnace replacement. If I find a crack during diagnostic, I red-tag the unit on the spot and show you our three replacement tiers. Learn more about CO safety at the EPA.

Join Frosty ClubTexas winters are mild, but furnaces still need regular service — and when they fail on a 28°F January morning, they tend to fail all at once. Here's what I see most often on McKinneyheating calls, and what each one typically costs to fix.
Failed hot-surface ignitor ($400) or coated flame sensor ($400). Both are same-day fixes. The $85 diagnostic identifies the exact cause.
Usually a failed ignitor, bad flame sensor, or a stuck gas valve. We run a combustion analysis to confirm the exact cause before quoting.
Dying inducer motor ($500-$1,300) — the draft fan pulling combustion gases through the heat exchanger. Replace before it takes out the control board.
Dirty flame sensor, failing limit switch, or restricted airflow. Can be an early warning of a heat exchanger issue — we diagnose carefully.
EMERGENCY — leave the house, call Atmos Energy at 866-322-8667, then call us. We locate the leak source and repair or red-tag as required.
Carbon monoxide risk — NEVER repaired. Full furnace replacement required for safety. We confirm with combustion analyzer and bore-scope inspection.
McKinney's 20–30 hard-freeze nights a year are enough to expose every furnace weakness that hid through summer dormancy. Most no-heat calls we roll on in December and January come from Stonebridge Ranch and the Eldorado Pkwy corridor — 1990s-era 80% AFUE furnaces on their second or third hot-surface ignitor. The repair pattern is predictable: hot-surface ignitors ($400 flat / $340 Frosty Club), sooted flame sensors ($400 / $340), and stuck or slow gas valves ($400–$1,200 / $340–$1,020). Atmos Energy delivers natural gas across McKinney, and if you ever smell sulfur or rotten eggs, leave the house immediately and call Atmos before calling us — that's a gas leak protocol, not an HVAC repair. Pre-1950 Historic Downtown homes near the square are the outliers: gravity-vented furnaces in floor registers that predate mandatory draft inducers and need specialty diagnostic attention most franchise shops skip entirely.
Cracked heat exchangers are the one failure I refuse to negotiate on. A cracked exchanger leaks combustion gases — including carbon monoxide — into the supply air flowing to your family's bedrooms. Per EPA indoor air quality guidance (EPA.gov), chronic low-level CO exposure causes headaches, fatigue, and cardiovascular strain. I don't weld heat exchangers because a field weld can't restore OEM flame pattern or material thickness — when I find a crack, I condemn the furnace, explain why, and quote full replacement. Every McKinney diagnostic includes a calibrated combustion-analyzer CO reading at the supply register plus a visual inspection of the exchanger wherever the burner assembly allows access. In my 8 years serving McKinney, I've condemned about one heat exchanger per month across Stonebridge Ranch's aging furnace stock — it's that common in 25-year-old equipment.
Craig Ranch, Tucker Hill, Trinity Falls, and newer Adriatica homes often run heat pumps instead of gas furnaces — a smart fit in McKinney's climate where real heating demand spans only 20–30 nights. Heat pump winter failures look different: defrost control boards ($450–$650), reversing valves stuck or refusing to actuate ($900–$1,500), and low-voltage transformer damage from Oncor power surges during storm restoration. If your outdoor unit puffs steam on a 28°F morning, that's a normal defrost cycle — the system briefly runs cooling mode to melt ice off the outdoor coil.

Deeper context on heating repair written by Omar Jacobo (EPA 608 #2396328).
Furnace repair in McKinney typically costs $250–$1,300 at Frosty's HVAC, with our $85 diagnostic waived when you approve the repair. Flat-rate prices: hot-surface ignitor $400 ($340 Frosty Club), flame sensor $400 ($340), gas valve $400–$1,200 ($340–$1,020), inducer motor $500–$1,300 ($425–$1,105), pressure switch $250–$550 ($212.50–$467.50). Cracked heat exchanger = full furnace replacement required (never field-repaired). Frosty Club Premium ($300/yr) saves 15% plus a $500 repair credit.
No — shut it down at the thermostat immediately. A cracked heat exchanger leaks combustion byproducts including carbon monoxide into conditioned air. Per EPA carbon monoxide guidance (EPA.gov), even low-level chronic exposure causes headaches, fatigue, and heart strain. Field welds don't restore OEM specs — we condemn cracked exchangers and quote a full furnace replacement. Our diagnostic always includes a combustion-analyzer CO reading at the nearest supply register. If you need emergency heat while waiting for replacement, portable electric space heaters are the safe interim.
Yes — newer McKinney builds lean heavily on heat pumps, especially in Trinity Falls (2018+), Craig Ranch, Tucker Hill, and Adriatica. Common heat-pump winter failures: defrost board faults, reversing valve stuck mid-cycle, outdoor TXV starving in heating mode. We service every residential brand on the North Texas slab: Trane, Carrier, Goodman, Lennox, Rheem, Bryant, Amana, York, Heil, and Payne. Same flat-rate pricing whether it's gas or electric. Qualifying heat pump repairs may factor into your decision on whether to repair or upgrade to an ENERGY STAR model eligible for up to $2,000 in IRA tax credits.
Three top causes: a dirty flame sensor that loses flame signal every 90 seconds (60% of short-cycle calls — resolves for $400 flat with sensor cleaning and reseating), airflow restriction tripping the high-limit switch (clogged filter or caked blower wheel), or a pressure switch reading a failing inducer draft. The $85 diagnostic identifies which cause — I'll show you the actual meter reading so you're not trusting me blind. Chronic short-cycling wastes 20–30% of your heating energy according to Energy.gov and accelerates wear on every ignition component.
The first cold-morning run of the season normally produces a brief burnt-dust smell as summer dust burns off the exchanger and ignitor — clears in 10–15 minutes, harmless. Different story for an electrical ozone smell (motor windings overheating — shut off at the breaker and call us) or sulfur/rotten eggs (natural gas leak — leave the house, call Atmos Energy at their emergency line first, then us). When in doubt, shut it down and call (469) 254-0548. An $85 diagnostic is cheaper than guessing wrong.
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.
Yes — heat pumps and ACs use the same refrigerant rules. EPA 608 Universal cert #2396328 covers R-410A heat pump service. AIM Act 2025 phase-out (Energy.gov) only stops new equipment manufacture — existing Stonebridge Ranch and Craig Ranch heat pumps stay serviceable. Repair cost runs the same as AC: $250-$500 for leak detection plus $100/lb recharge. Repair is usually right unless the system is past 12 years old. Read our R-410A phase-out explainer for DFW homeowners.
