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 DeSoto?

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 DeSotoheating 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 DeSotoHomeowners Trust Frosty's for Heating Repair

DeSoto heating repair work is concentrated in three failure modes that all show up when temperatures drop into the 20s: hot-surface ignitors ($400), dirty flame sensors ($400), and stuck gas valves ($400-$1,200). Thorntree and Eagle Ford 1970s-80s ranch homes run original-sized 80% AFUE furnaces that sat idle from April through October, and the dust loads that build up on flame sensors over a hot DeSoto summer cause nuisance lockouts the first cold week of December every year. Hampton Creek and Windmill Hill two-stories from the 1990s-2000s have aged enough now that inducer motors ($500-$1,300) are starting to grind and fail during startup — another call we get a lot in 75115 every January.

The heat exchanger is the component we worry about most on DeSoto furnaces, especially the older Thorntree and Eagle Ford systems that have been through 30+ winters. A cracked heat exchanger leaks combustion gas — including carbon monoxide — directly into your supply air, and that's not something we repair. We condemn the furnace and quote a replacement. Every DeSoto heating diagnostic includes a CO check at the supply register and a visual inspection of the heat exchanger wherever we can access it. If I see rust streaks, flame impingement marks, or stress cracks, I tell you straight. I'd rather lose a repair job than let a DeSoto family breathe CO.

Heat pump calls in DeSoto have grown a lot as newer Hampton Creek builds and some Eagle Ford renovations moved to all-electric systems. Heat pump failures look different than gas furnaces: failed defrost boards, bad reversing valves, outdoor TXV issues, and electric heat strip failures when DeSoto temperatures drop below 15°F. Heat pumps run briefly in cooling mode during defrost to melt ice off the outdoor coil — so if you see steam rising off the outdoor unit on a cold morning, that's normal operation, not a problem. Call (469) 254-0548 and we'll diagnose the real issue for $85 (waived with repair).

Heating Repair FAQ for DeSoto, TX

How much does furnace repair cost in DeSoto, TX?

Diagnostic $85 flat (waived with repair). Common DeSoto 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. We're 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 DeSoto heating diagnostic includes a heat exchanger inspection and CO check at the supply register, especially on older Thorntree and Eagle Ford systems.

Why does my DeSoto furnace short-cycle?

Short cycling on a DeSoto furnace is almost always one of three things: a dirty flame sensor (most common — DeSoto's long hot summers leave heavy dust buildup), overheating from restricted airflow (clogged filter or dirty blower wheel), or a failing pressure switch. The $85 diagnostic identifies the cause. Flame sensor cleaning is $400 flat ($340 for members) and solves 60% of these calls.

Do you repair heat pumps in DeSoto?

Yes. Many newer Hampton Creek and Windmill Hill 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.

My DeSoto 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 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 DeSoto for a no-heat call?

We're about 40 minutes from DeSoto down I-35E, so same-day response is routine across 75115. 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.
