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 Dallas?

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 Dallasheating 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 DallasHomeowners Trust Frosty's for Heating Repair

Dallas doesn't have Chicago winters, but we still see 20-30 freeze nights a year and the occasional multi-day hard freeze (remember February 2021). That's enough cold to expose every weak point in a furnace that sat unused from April through October. The calls we get from Dallas 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 present the same way — furnace tries to light, fails, goes into lockout. For 1930s-50s Preston Hollow and Lakewood homes, I also see aging inducer motors ($500-$1,300) that grind or fail to spin up, and original gravity-vent flues that can't keep up with modern 80% furnaces retrofitted into them.

The heat exchanger is the component I worry about most, especially on older Dallas systems. 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 Dallas 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 Preston Hollow or Lakewood family breathe CO because I didn't catch it.

Uptown high-rises, Deep Ellum lofts, and newer North Dallas builds often have heat pumps instead of gas furnaces — especially in buildings where gas service is limited. Heat pump winter failures are different: failed defrost boards, bad reversing valves, TXV issues on the outdoor unit, and electric heat strip failures when the outdoor temp drops below 15°F. Heat pumps run briefly in cooling mode during a defrost cycle to melt ice off the outdoor coil, so if you see steam off the outdoor unit on a cold Dallas 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 Dallas, TX

How much does furnace repair cost in Dallas, TX?

Diagnostic $85 flat (waived with repair). Common Dallas 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 Dallas diagnostic includes a heat exchanger inspection and CO check at the supply register, especially on older prewar Preston Hollow and Lakewood systems.

Do you repair heat pumps in Dallas?

Yes. Uptown high-rises, Deep Ellum lofts, and many newer North Dallas builds use 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.

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

Short cycling on a furnace is usually a dirty flame sensor (most common), overheating from restricted airflow (clogged filter or dirty blower — rampant in Preston Hollow Tudors with undersized returns), 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 Dallas furnace smells like something burning — should I call?

First time in the fall when you kick the heat on — that's usually dust burning off the heat exchanger and goes away 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.
