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.

What Are the Most Common Heating Problems in Lancaster?

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 Lancasterheating 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 LancasterHomeowners Trust Frosty's for Heating Repair

Lancaster heating repair work is dominated by gas furnace service because Lancaster has long-established Atmos gas infrastructure throughout the city. Historic Lancaster around the Town Square has furnaces that have been replaced multiple times since the original retrofit — current systems are usually 1990s-2000s 80% AFUE units approaching end of life. Lancaster Lakes and Bluegrove 1990s-2000s homes run the first or second furnace generation. Ten Mile Creek and I-35E corridor 2000s-2010s homes often have 96% AFUE condensing units with PVC venting.

When temperatures drop into the 20s, Lancaster heating calls cluster into the usual trio: hot-surface ignitors ($400), dirty flame sensors ($400), and stuck gas valves ($400-$1,200). Inducer motor failures ($500-$1,300) are climbing as the 1990s-2000s installed base ages out. For newer Ten Mile Creek homes with 96% AFUE condensing furnaces, pressure switch issues from clogged PVC venting are a common ice-event call — snow or debris blocks the intake or exhaust and the unit locks out until it clears.

The heat exchanger is the component we worry about most on older Lancaster furnaces. 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 Lancaster heating diagnostic includes a CO check at the supply register and a visual heat exchanger inspection, especially on older Historic Lancaster and Lancaster Lakes systems. Call (469) 254-0548 for a $85 diagnostic (waived with repair).

Heating Repair FAQ for Lancaster, TX

How much does furnace repair cost in Lancaster, TX?

Diagnostic $85 flat (waived with repair). Common Lancaster 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 Lancaster heating diagnostic includes a heat exchanger inspection and CO check at the supply register, especially on older Historic Lancaster and Lancaster Lakes systems.

Why does my Lancaster furnace keep going into lockout?

Lockout codes usually come from one of three failures: a dirty flame sensor (most common — summer dust buildup insulates it), a failed hot-surface ignitor (cracked or shorted), or a pressure switch issue (especially on 96% AFUE condensing units where PVC venting can clog). 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 Lancaster?

Yes. Some newer Ten Mile Creek and Lancaster Lakes 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. We service Carrier, Trane, Goodman, Lennox, Rheem, and all major residential brands.

My Lancaster furnace smells like something burning — is that normal?

First time in the fall when you kick the heat on — yes, that's dust burning off the heat exchanger and it clears in a few minutes. Normal. If the smell persists, smells electrical, or smells like gas, shut the system off at the thermostat 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 Lancaster for a no-heat call?

We're about 45 minutes from Lancaster down I-35E, so same-day response is routine across 75134. 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.
