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 Little Elm?
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 Little Elmheating 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 Little ElmHomeowners Trust Frosty's for Heating Repair
North Texas doesn't have Chicago winters, but Little Elm still sees 20-30 freeze nights a year, and that's enough to expose every weak point in a furnace or heat pump that sat unused from April to October. Because most Little Elm homes were built in the 2010s-2020s, a lot of what we see is heat-pump-specific — defrost board faults, failed reversing valves, and outdoor TXV issues on variable-speed heat pumps in Paloma Creek, Hillstone Pointe, and Frisco Lakes. For gas furnace homes, the December-January calls are dominated by cracked hot-surface ignitors ($400), dirty flame sensors ($400), and stuck gas valves ($400-$1,200).
The heat exchanger is the one I worry about most on gas furnace 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 Little Elm 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.
For heat pump homes — most of the newer Little Elm builds — winter failures look totally different. Failed defrost boards, bad reversing valves, and TXV issues on the outdoor unit top the list. Heat pumps briefly run in cooling mode during defrost cycles to melt ice off the outdoor coil, so if you see steam coming off the outdoor unit on a cold morning, that's normal — not a problem. Communicating heat pump systems (Carrier Infinity, Trane XL, Lennox) in Paloma Creek also see low-voltage comm faults that knock the whole system offline. Call (469) 254-0548 and we'll diagnose whatever's actually wrong for $85 (waived with repair).

Heating Repair FAQ for Little Elm, TX
How much does furnace repair cost in Little Elm, TX?
Diagnostic $85 flat (waived with repair). Common Little Elm 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 Little Elm diagnostic includes a heat exchanger inspection and CO check at the supply register.
Do you repair heat pumps in Little Elm?
Yes — most 2010s-2020s Little Elm builds in Paloma Creek, Hillstone Pointe, and Frisco Lakes use heat pumps instead of gas furnaces. Common heat pump failures include defrost board faults, failed reversing valves, outdoor TXV issues, and low-voltage comm faults on communicating systems. We service Carrier, Trane, Goodman, Lennox, Rheem, and all major residential brands.
Why does my Little Elm heat pump run in cooling mode when it's freezing outside?
That's the defrost cycle, and it's normal. Heat pumps briefly reverse into cooling mode to melt ice off the outdoor coil during cold weather. You'll see steam rising off the unit for 5-10 minutes, then it switches back to heating. If it stays in defrost longer than 15 minutes or cycles defrost every few minutes, the defrost board or sensor is failing — that's a $400-$700 repair.
My Little Elm heater smells like burning when I first turn it on — should I call?
First time in the fall — that's usually dust burning off the heat exchanger (gas furnace) or the heat strips (heat pump) 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 the gas company first.
