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 Midlothian?
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 Midlothianheating 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 Do Midlothian Homeowners Choose Frosty's for Heating Repair?
Midlothian heating repair is predominantly gas furnace service because Atmos Energy natural gas runs through virtually every neighborhood in 76065, from Lake Ridge and Crystal Forest Estates to the newest BridgeWater and Redden Farms master-planned communities. Lake Ridge and Crystal Forest Estates 2000s-era homes run 60,000-80,000 BTU builder-grade gas furnaces that are now 15-20 years old and entering peak failure years. The three winter failure modes that stack up every December and January: hot-surface ignitors ($400, $340 for Frosty Club members), dirty flame sensors ($400, $340), and stuck or failing gas valves ($400-$1,200, $340-$1,020). BridgeWater, Redden Farms, and Hawkins Meadow 2010s-2020s builds have newer furnaces that typically need only basic maintenance, but inducer motor and pressure switch failures can still happen on these systems under Ellis County freeze conditions.
The heat exchanger is the furnace component I take most seriously on any Midlothian heating call. Midlothian's explosive growth from 5,141 residents in 1990 to over 35,000 by 2020 means thousands of furnaces were installed in the same build window and are aging together. A cracked heat exchanger leaks combustion byproducts including carbon monoxide directly into your supply air, and that is not a component we repair. We condemn the furnace and quote a full replacement. Every Midlothian heating diagnostic I run includes combustion analysis at the supply register with a calibrated CO meter and visual heat exchanger inspection. I'm Omar Jacobo, EPA 608 Universal certified (#2396328), and if I find rust streaks, flame impingement marks, or stress cracks on a Lake Ridge or Crystal Forest Estates furnace, I tell you immediately because per CPSC guidance, CO exposure is a medical emergency.
Inducer motor failures ($500-$1,300, $425-$1,105 for Frosty Club members) are climbing across Midlothian as the 2000s furnace generation passes 15-20 years, particularly in Lake Ridge, Crystal Forest Estates, and Mockingbird Estates where those vintage units are entering the highest-risk window. When inducer motor bearings fail, the furnace hums on startup but never completes the ignition sequence and you get lockout codes with no heat. Mountain Peak acreage estates with larger 100,000 BTU furnaces see similar failure patterns on a bigger scale.

What Do Midlothian Homeowners Ask About Heating Repair?
What Does Furnace Repair Cost in Midlothian, TX?
Flat-rate diagnostic $85 (waived with repair). Common Midlothian furnace repairs: hot-surface ignitor $400 ($340 for members), flame sensor service $400 ($340), gas valve $400-$1,200 ($340-$1,020), inducer motor $500-$1,300 ($425-$1,105), pressure switch $250-$550. You see the total on the quote before work begins. No hourly meter and no surprise line items.
Is My Midlothian Furnace Safe with a Cracked Heat Exchanger?
No. A cracked heat exchanger leaks combustion byproducts including carbon monoxide directly into your supply air, creating a serious health hazard. We do not repair cracked heat exchangers because they cannot be welded safely to spec. We condemn the furnace and quote a full replacement. Every Midlothian heating diagnostic includes heat exchanger inspection and calibrated CO testing, especially critical on aging Lake Ridge and Crystal Forest Estates furnaces.
Why Does My Midlothian Furnace Lock Out After Trying to Ignite?
Ignition lockout traces to one of three causes: dirty flame sensor (most common because long idle Texas summers leave heavy dust and pollen buildup on the sensor rod), overheating from restricted airflow through a clogged filter or dirty blower wheel, or a failing pressure switch. The $85 diagnostic identifies which. Flame sensor service at $400 flat ($340 for members) resolves about 60% of these lockout calls across Lake Ridge, Crystal Forest Estates, and BridgeWater homes.
Do You Service Heat Pumps in Midlothian?
Yes. A growing number of newer BridgeWater, Redden Farms, and Villages of Walnut Grove homes run heat pumps instead of gas furnaces, especially all-electric builds pursuing the $2,000 federal 25C tax credit. Common heat pump heating failures include defrost board faults at $400-$700, failed reversing valves, outdoor TXV issues, and electric heat strip failures during sub-15 degree stretches. Per EPA 608 rules, low refrigerant always means a leak we locate first.
How Fast Can Frosty's Respond to a Midlothian No-Heat Emergency?
About 45 minutes from our Farmers Branch shop via US-287 and US-67. During freeze events we prioritize no-heat calls in homes with kids, pets, or elderly residents across all of 76065. Frosty Club members get priority scheduling and Premium members pay no overtime surcharge at $85 after-hours versus $250 for non-members. Call (469) 251-0858 for immediate dispatch.
Should I Upgrade My Lake Ridge Furnace from 80% to 96% AFUE?
If you are replacing the furnace anyway, the efficiency upgrade from 80% to 96% AFUE typically saves $200-$400 per year on Atmos Energy gas bills across a Midlothian winter. The catch is venting: 96% AFUE condensing furnaces vent through PVC instead of the metal B-vent, so the new vent route needs planning before install. Gas furnaces at 96% AFUE or above also qualify for up to $600 in federal 25C tax credits.
