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 Mansfield?
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 Mansfieldheating 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 MansfieldHomeowners Trust Frosty's for Heating Repair
Mansfield heating repair work is dominated by gas furnace service because Mansfield has long-established Atmos gas infrastructure throughout the city. Walnut Creek Valley and Lake Ridge 1990s-2000s homes typically run 80,000-120,000 BTU 80% AFUE gas furnaces that are now hitting 20-30 years of service. Heritage Glen 2000s-2010s homes often have early 90%+ AFUE units. Twin Creeks and newer US-287 corridor builds mostly run 96% AFUE condensing furnaces with PVC flue venting. When temperatures drop into the 20s, the usual call mix is hot-surface ignitors ($400), dirty flame sensors ($400), and stuck gas valves ($400-$1,200).
Inducer motor failures ($500-$1,300) are a growing Mansfield call because the big 1990s-2000s installation wave is now aging out. When the inducer motor bearings go, the furnace hums on startup but won't complete the ignition sequence — lockout codes and no heat. We diagnose with a static pressure reading on the vent, current draw check, and visual bearing inspection. For 96% AFUE condensing furnaces in Twin Creeks and Heritage Glen homes, pressure switch issues from clogged PVC venting are a common ice-event call.
The heat exchanger is the component we worry about most on older Walnut Creek Valley and Lake Ridge furnaces — some are now 25-30 years old. A cracked heat exchanger leaks combustion gas — including carbon monoxide — directly into your supply air, and we don't repair it. We condemn the furnace and quote a replacement. Every Mansfield heating diagnostic includes a CO check at the supply register and a visual heat exchanger inspection. Call (469) 254-0548 for a $85 diagnostic (waived with repair).

Heating Repair FAQ for Mansfield, TX
How much does furnace repair cost in Mansfield, TX?
Diagnostic $85 flat (waived with repair). Common Mansfield furnace repairs: hot-surface ignitor $400 ($340 for members), flame sensor clean $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 furnace safe to run if the heat exchanger is cracked?
No. A cracked heat exchanger leaks combustion gas — including carbon monoxide — directly into your supply air. We don't repair cracked heat exchangers because they can't be safely welded to spec. Instead we condemn the furnace and quote a full replacement. Every Mansfield heating diagnostic includes a heat exchanger inspection and CO check at the supply register, especially on older Walnut Creek Valley and Lake Ridge systems.
Why does my Mansfield furnace keep going into lockout?
Lockout on a Mansfield furnace is usually one of three things: a dirty flame sensor (most common), overheating from restricted airflow, or a failing pressure switch on 96% AFUE condensing units. The $85 diagnostic identifies which one. Flame sensor cleaning is $400 flat ($340 for members) and solves 60% of lockout calls.
Do you repair heat pumps in Mansfield?
Yes. Some newer Twin Creeks and Heritage Glen homes run heat pumps instead of gas furnaces. Common heat pump failures include defrost board faults, failed reversing valves, outdoor TXV issues, and electric heat strip failures when temperatures drop below 15°F. We service Carrier, Trane, Goodman, Lennox, Rheem, and all major residential brands.
My Mansfield furnace smells like burning dust — normal?
First time in the fall when you kick the heat on — yes, that's dust burning off the heat exchanger and clears in a few minutes. Normal. If the smell persists, smells electrical, or smells like gas, shut the system off and call us at (469) 254-0548. Electrical smells mean an overheating motor; gas smell means leave the house and call Atmos first.
How fast can you get to Mansfield for a no-heat call?
We're about 50 minutes from Mansfield down I-35E and US-287, so same-day response is routine across 76063. During freeze events we prioritize no-heat calls in homes with kids, pets, or elderly residents. Frosty Club members get priority scheduling and no overtime charges. Call (469) 254-0548.
