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 Red Oak?
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 Red Oakheating 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 Red Oak Homeowners Choose Frosty's for Heating Repair?
Heating repair in Red Oak is almost entirely gas furnace work because Atmos Energy runs natural gas throughout the 75154 ZIP and builders have defaulted to gas heat for every era of Red Oak construction. Red Oak Creek and Live Oak Creek Estates homes from the 2000s typically carry 60,000-100,000 BTU 80% AFUE gas furnaces that are now 15-20 years old and entering the window where ignitor failures, flame sensor issues, and inducer motor bearing wear become annual events. Newer builds in The Oaks and Red Oak Crossing run 96% AFUE condensing furnaces with PVC flue venting — different failure modes, but still gas. When Ellis County temperatures drop into the low 20s, Red Oak heating calls spike overnight as furnaces that sat idle since March attempt ignition and fail.
The heating repair mix in Red Oak shifts by housing era. On 2000s-era Red Oak Creek and Live Oak Creek Estates furnaces, hot-surface ignitor replacement ($400, $340 for members) is the single most common call — these ceramic elements crack from thermal cycling over 15-plus winters. Flame sensor cleaning ($400, $340 member) and gas valve replacement ($400-$1,200, $340-$1,020 member) round out the top three. Inducer motor failures ($500-$1,300) are rising as the 2000s installation wave crosses the 15-year mark. On 96% AFUE condensing furnaces in The Oaks and Red Oak Crossing, pressure switch faults ($250-$550) from clogged or ice-blocked PVC intake are the recurring issue — one ice storm can plug the intake pipe overnight.
The component I take most seriously on Red Oak heating calls is the heat exchanger. Red Oak Creek originals pushing 20 years have logged enough thermal cycles for stress cracks to develop. A cracked heat exchanger leaks combustion gas — including carbon monoxide — into your supply air, and I do not repair them because a field weld cannot restore factory integrity. We condemn the furnace and quote replacement. Every Red Oak heating diagnostic includes a CO check at the supply register and a visual heat exchanger inspection. I hold EPA 608 Universal certification (#2396328), our TACLA126718E license covers all Texas residential work, and 99 Google reviews at 4.9 stars confirm the standard. Se Habla Espanol.

What Do Red Oak Homeowners Ask About Heating Repair?
How much does furnace repair cost in Red Oak, TX?
Diagnostic $85 flat (waived with repair). Common Red Oak 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. All flat-rate — you see the total before we start work.
Why does my Red Oak Creek furnace keep going into lockout mode?
Lockout on a Red Oak Creek 2000s-era furnace is usually one of three things: a cracked hot-surface ignitor that fails to light the gas (most common after 15 years), a dirty flame sensor that shuts down ignition after a few seconds of flame, or a pressure switch fault from restricted venting. The $85 diagnostic identifies which. Flame sensor cleaning ($400, $340 for members) resolves about 60% of lockout calls.
Is a cracked heat exchanger dangerous in my Red Oak home?
Yes — extremely dangerous. A cracked heat exchanger leaks combustion gas including carbon monoxide directly into the air your family breathes. We do not repair cracked heat exchangers because field welds cannot restore factory safety. We condemn the furnace and quote full replacement. Every Red Oak heating diagnostic on 15-plus year old equipment includes a heat exchanger inspection and CO check.
My furnace in The Oaks is only 5 years old — why is it failing?
Newer 96% AFUE condensing furnaces in The Oaks and Red Oak Crossing fail differently than older 80% AFUE units. The most common early-life issue is a pressure switch fault from a clogged or ice-blocked PVC intake — one Ellis County ice storm can plug the pipe overnight. Flame sensor carboning and inducer motor control board glitches also occur on newer units. The $85 diagnostic identifies the cause.
Do you repair heat pumps in Red Oak?
Yes. Some all-electric homes in The Oaks and newer Red Oak Crossing builds run heat pumps instead of gas furnaces. Common heat pump heating failures include defrost board faults, failed reversing valves, outdoor TXV issues, and electric heat strip failures when temperatures drop below 15 degrees. We service Carrier, Trane, Goodman, Lennox, Rheem, and all major residential brands.
My Red Oak furnace smells like burning — should I call for emergency service?
First fall startup dust-burn is normal and clears in minutes. If the smell persists, turns electrical, or smells like gas, shut off the system immediately. Electrical smell means an overheating motor. Gas smell means leave the house and call Atmos Energy first, then call us at (469) 251-0858. We can be in Red Oak within 2-3 hours for emergencies.
