Unfortunately, if your furnace has a cracked heat exchanger, it’s time to choose between repairing or replacing your unit. Making this decision, however, is often easier said than done. In order to help you evaluate your current situation and take the right steps forward, here’s a guide to dealing with a cracked heat exchanger.

Why should I be concerned about a cracked heat exchanger?

Rule #1: If your Heat Exchanger has been deemed cracked by a HVAC professional you should NOT be running it. Unfortunately, some owners will attempt to run their furnace even when a cracked heat exchanger has been detected. It’s important that you understand there’s a good reason behind your furnace being red tagged, or taken out of commission. Choosing to ignore the warning could yield serious consequences.

A crack in the heat exchanger can allow poisonous carbon monoxide (CO) to leak into your home, leading to illness or even death. Additionally, because your heat exchanger is such an integral part of your heating system, it’s typically an expensive problem. Therefore, any cracks found in your heat exchanger should be addressed promptly in order to maintain safety and comfort.

Which is best: repairing or replacing my furnace?

Hiring your HVAC contractor to fix your heat exchanger may initially seem less expensive, but repairs should only be considered when:

  • Your furnace is under 10 years old

  • Repair parts are completely covered under manufacturer warranty

  • Labor costs are less than 25 percent of the cost to replace

Even if your situation meets these criteria, you should still consider upgrading your furnace.
