What Is Going Wrong?
The heat exchanger separates combustion gases from the air your family breathes. A crack, rust-through, or failed weld can let carbon monoxide into the supply air, and it cannot be reliably patched. If an inspection finds a cracked heat exchanger, the honest answer is usually replacement of the furnace, and the furnace should not run until that decision is made.
Common Causes
- Age, heat cycling, and metal fatigue over many winters
- Overheating from restricted airflow or a clogged filter
- Rust and corrosion, especially in older furnaces
- A furnace that was oversized and short-cycled for years
Signs You Need This Service
- A carbon monoxide alarm going off, or headaches and nausea near the furnace
- Soot around the furnace, or a strange smell when heat runs
- A flame that flickers or changes when the blower starts
- An inspector or technician flagging a crack or rust-through
What We Check, In Order
- Visual inspection, plus combustion and carbon monoxide testing
- Flame behaviour when the blower starts, a classic crack clue
- Venting and airflow that may have caused overheating
- Whether the furnace is safe to run at all, before any other work
Why Choose Us for This Furnace Job
- We diagnose in order, so the real fault gets fixed, not just the obvious part.
- You get an upfront price before work starts, and you decide with no pressure.
- After the repair we test ignition, airflow, and safety switches, and we clean up before we leave.
Repair or Replace?
| Situation | Honest next step |
|---|---|
| One failed part, furnace under 12 years old | Repair is usually the right call |
| Repeated failures, or a cracked heat exchanger | Price replacement, and do not run an unsafe furnace |
| Repair near half the cost of a new furnace | Get both options in writing before deciding |
Safety note: If you smell gas, leave the home and call from outside. If a carbon monoxide alarm sounds, leave and call emergency services, then call us.
