Heat exchanger cracks are more common in Colorado than most places. The altitude puts extra stress on combustion equipment, and our long heating season means furnaces run thousands of hours per year. A cracked heat exchanger can leak carbon monoxide into your home — this is the most serious furnace problem we encounter.
We inspect the heat exchanger on every furnace repair call. If we find a crack, we'll explain your options honestly. In most cases, a cracked heat exchanger means it's time for a new furnace rather than a $1,000-$3,500 repair on an aging system.
Most furnace repairs cost $150-$700. Ignitor replacements run $150-$350, blower motors $300-$700, and control boards $400-$900. Heat exchanger replacement ($1,000-$3,500) usually means a new furnace is a better investment.

Check your thermostat setting, air filter, and circuit breaker first. If those are fine, it's likely an ignitor, flame sensor, or control board issue that needs professional diagnosis.
