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 Lake Dallas?
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 Lake Dallasheating 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 Lake DallasHomeowners Trust Frosty's for Heating Repair
Lake Dallas heating calls concentrate December through February when Denton County takes its 20-30 freeze nights. The split housing stock means we see two distinct heating populations: older Lake Dallas Estates and Garza Street cottages often run 20-30 year old 80% AFUE gas furnaces that are past their service life, while newer Hickory Lake Estates homes run 90-96% AFUE condensing furnaces or heat pumps tied to variable-speed blowers. Age-typical failures: hot-surface ignitors ($400), flame sensors ($400), pressure switches ($250-$550), and inducer motors ($500-$1,300).
The heat exchanger is what I take most seriously on any Lake Dallas system 15+ years old — and plenty of Lake Dallas Estates cottages still have original 1990s-early 2000s furnaces. A cracked heat exchanger leaks CO into the supply air that circulates through every room. We don't repair cracked heat exchangers — they can't be safely welded to factory spec. Instead we condemn the furnace and quote full replacement. Every Lake Dallas diagnostic on an older system includes a CO check at a supply register.
Newer Lake Dallas waterfront and Hickory Lake Estates builds often 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 temps drop below 15°F. Heat pumps briefly run in cooling mode 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 for $85 diagnostic (waived with repair).

Heating Repair FAQ for Lake Dallas, TX
How much does furnace repair cost in Lake Dallas, TX?
Diagnostic $85 flat (waived with repair). Common Lake Dallas 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 Lake Dallas cottage furnace safe with a cracked heat exchanger?
No. A cracked heat exchanger leaks combustion gases — including carbon monoxide — into your supply air, which circulates through every room. We don't repair cracked heat exchangers because they can't be safely welded to factory spec. On 20-30 year old Lake Dallas Estates and Garza Street cottage furnaces, cracked exchangers are common, and replacement is the only safe answer.
Do you repair heat pumps in Lake Dallas?
Yes. Many Lake Dallas waterfront and Hickory Lake Estates homes use heat pumps with electric heat strip backup. 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 Lake Dallas 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, or a failing pressure switch. The $85 diagnostic identifies the cause. Flame sensor cleaning solves 60% of these calls.

During hard freezes we prioritize no-heat calls. Business-hours response is typically within 2 hours for 75065 Lake Dallas addresses; Frosty Club Premium members get same-hour response when available.
