Cracked Heat Exchanger: Safety First
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 ClubWhat Are the Most Common Heating Problems in Lucas?
Texas 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 Lucasheating calls, and what each one typically costs to fix.
Furnace won't ignite
Failed hot-surface ignitor ($400) or coated flame sensor ($400). Both are same-day fixes. The $85 diagnostic identifies the exact cause.
Blowing cold air instead of hot
Usually a failed ignitor, bad flame sensor, or a stuck gas valve. We run a combustion analysis to confirm the exact cause before quoting.
Loud buzzing or grinding
Dying inducer motor ($500-$1,300) — the draft fan pulling combustion gases through the heat exchanger. Replace before it takes out the control board.
Short cycling (on/off/on/off)
Dirty flame sensor, failing limit switch, or restricted airflow. Can be an early warning of a heat exchanger issue — we diagnose carefully.
Gas smell or CO alarm
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.
Cracked heat exchanger
Carbon monoxide risk — NEVER repaired. Full furnace replacement required for safety. We confirm with combustion analyzer and bore-scope inspection.
Why LucasHomeowners Trust Frosty's for Heating Repair
Lucas heating repair calls concentrate from December through February when Collin County takes its 20-30 freeze nights. Lucas's 2000s-2010s custom homes run two-stage gas furnaces tied to variable-speed blowers, and the failures I see are age-typical: hot-surface ignitors ($400) cracking after 15 years of cycling, flame sensors ($400) carboned over from years of combustion deposits, pressure switches ($250-$550) stuck closed after summer dust accumulation, and inducer motors ($500-$1,300) that finally seized after two decades. Lucas Crossing and Stinson Highlands homes in the oldest pocket of the build hit that 20-year wall right about now, and we're starting to see compressor failures and heat exchanger cracks alongside the ignitor wear.
The heat exchanger is the component I take most seriously on Lucas systems hitting 15+ years. A cracked heat exchanger leaks carbon monoxide into the supply air, which circulates through every room of a 5,000 sqft custom. We don't repair cracked heat exchangers — they can't be safely welded to spec. Instead we condemn the furnace and quote full replacement. Every diagnostic in Lucas includes a CO check at a supply register and a visual heat exchanger inspection where access allows. On dual-furnace Lucas customs, we check both every time.
Some newer Lucas builds (especially in Brockdale's newest sections and near Trinity Falls) run heat pumps with electric heat strip backup instead of gas furnaces. Heat pump winter failures look different: failed defrost boards, bad reversing valves, outdoor TXV issues, electric heat strip element failures when the outdoor temp drops below 15°F. Heat pumps briefly reverse to cooling during defrost cycles to melt ice off the outdoor coil, so steam off the unit on a 25°F morning is normal. Call (469) 254-0548 and we'll diagnose whatever's actually wrong for $85 (waived with repair).

Heating Repair FAQ for Lucas, TX
How much does furnace repair cost in Lucas, TX?
Diagnostic $85 flat (waived with repair). Common Lucas furnace repairs: hot-surface ignitor $400 ($340 for Frosty Club members), flame sensor $400 ($340), gas valve $400-$1,200 ($340-$1,020), inducer motor $500-$1,300 ($425-$1,105), pressure switch $250-$550. Flat-rate — you see the total before we start.
Is my Lucas furnace safe with a cracked heat exchanger?
No. A cracked heat exchanger leaks combustion gases — including carbon monoxide — into your supply air. We don't repair cracked heat exchangers because they can't be safely welded to factory spec. Instead, we condemn the furnace and quote a full replacement. Every Lucas diagnostic includes a heat exchanger inspection and CO check at a supply register on systems 15+ years old.
Do you repair heat pumps in Lucas?
Yes. A subset of newer Lucas builds (Brockdale newest sections, Trinity Falls area) use heat pumps with electric heat strip backup instead of gas furnaces. Common failures include defrost board faults, failed reversing valves, outdoor TXV issues, and electric heat strip element failures. We service Carrier, Trane, Goodman, Lennox, Rheem, and all major residential brands.
My Lucas furnace keeps shutting off after a few minutes — why?
Short cycling on a furnace usually means a dirty flame sensor (most common, $400 flat to clean/replace), overheating from restricted airflow (clogged filter on a big dual-zone system is common), or a failing pressure switch. The $85 diagnostic identifies the cause. On big Lucas customs with 20+ supply registers, clogged filters on the zoning side are an overlooked suspect.
Cold snap hit Lucas and my heat died — how fast can you come out?
During hard freezes we prioritize no-heat calls. Business-hours response is typically within 2-3 hours for most 75002 Lucas addresses; Frosty Club Premium members get same-hour response when available. After-hours emergency diagnostic is $250 for non-members, $212.50 for Basic members, $85 for Premium members. Call (469) 254-0548.
