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 Fort Worth?

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 Fort Worthheating 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 Fort WorthHomeowners Trust Frosty's for Heating Repair

Fort Worth winters are mild by most American standards, but we still see 20-30 freeze nights a year, and the Panhandle winds coming off the Trinity bottoms make those nights feel colder than the thermometer reads. The heating repair calls we get from Fort Worth in December and January are dominated by three failures: cracked hot-surface ignitors ($400), dirty flame sensors ($400), and stuck or failed gas valves ($400-$1,200). All three have the same symptom — furnace tries to light, fails, goes into lockout. In historic Fairmount, Arlington Heights, and Near Southside homes with 1990s or older furnaces, I also see a lot of aging inducer motors ($500-$1,300) that grind or fail to spin up.

The heat exchanger is the one I worry about most, especially in historic Fort Worth homes where the furnace lives in a tight attic closet or a hall utility space with marginal combustion air. Crack a heat exchanger and you get carbon monoxide in the supply air — which means we're not repairing it, we're condemning the furnace and quoting a full replacement. Every diagnostic we do in Fort Worth includes a CO check at the supply register and a visual inspection of the heat exchanger where we can access it. If I see rust, scale, or flame impingement, I tell you straight. I'd rather lose a repair job than let a family breathe CO.

If you have a heat pump instead of a gas furnace — common in newer North Fort Worth builds in 76137 and 76244, and in TCU-area rentals where the owner went all-electric — the winter failures are different: failed defrost boards, bad reversing valves, and TXV issues on the outdoor unit. Heat pumps run in cooling mode briefly during a defrost cycle to melt ice off the outdoor coil, so if you're seeing steam off the outdoor unit on a cold morning, that's normal — not a problem. Call (469) 254-0548 and we'll diagnose whatever's actually wrong for $85 (waived with repair).

Heating Repair FAQ for Fort Worth, TX

How much does furnace repair cost in Fort Worth, TX?

Diagnostic $85 flat (waived with repair). Common Fort Worth 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. We're flat-rate, so 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 gases — including carbon monoxide — directly into your supply air. We don't repair cracked heat exchangers because they can't be safely welded back to spec. Instead, we quote a full furnace replacement. Every Fort Worth diagnostic includes a heat exchanger inspection and CO check at the supply register. This matters especially in Fairmount and Arlington Heights historic homes where furnaces often sit in tight attic closets with marginal combustion air.

Do you repair heat pumps in Fort Worth?

Yes. Newer 76137 and 76244 North Fort Worth homes and TCU-area rentals often have heat pumps instead of gas furnaces. Common heat pump failures include defrost board faults, failed reversing valves, and outdoor TXV issues. We service Carrier, Trane, Goodman, Lennox, Rheem, and all major residential brands.

Why does my Fort Worth furnace keep shutting off after a few minutes?

Short cycling on a furnace is usually a dirty flame sensor (most common), overheating due to restricted airflow (clogged filter or dirty blower), or a failing pressure switch. The $85 diagnostic identifies the cause. Flame sensor cleaning runs $400 flat ($340 for members) and solves 60% of these calls.

My Fort Worth furnace smells like something burning — should I call?

First time in the fall — that's usually dust burning off the heat exchanger and goes away in a few minutes. Normal. If the smell persists, is 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 or wiring; gas smell means leave the house and call Atmos Energy first.
