\"natural-gas-burner\"We\u2019ve written before about the importance of having your furnace\u2019s heat exchanger regularly checked<\/a> by a professional. This is a part of our routine preventive maintenance program, the Ultimate Service Agreement<\/a>, and it\u2019s a vital inspection to make sure that a furnace operates as safely as possible. What our technicians look for when they examine a heat exchanger is signs of cracks along it or corrosion that can lead to those cracks. A cracked heat exchanger can allow toxic combustion gases to escape into the airflow moving into the rooms around a house\u2014a dangerous situation!<\/p>\n

Furnace owners often feel nervous when they learn their furnace may pose a safety risk. This leads to the question whether they should have the furnace repaired\u2014which means replacing the heat exchanger\u2014or instead have a new gas furnace installed<\/a>.<\/p>\n

A cracked heat exchanger usually means an over-the-hill furnace<\/h2>\n

The damage to a furnace\u2019s heat exchanger that can lead to cracks usually occurs because the heating system is near the end of its service life, probably older than 15 years and maybe 20. Corrosion is the most common of the aging effects that can trigger cracks in a heat exchanger. The reaction of combustion gases with the metal in the heat exchanger leads to corrosion over time (faster if there is poor ventilation).<\/p>\n

We don\u2019t recommend keeping a gas furnace that\u2019s more than 20 years old, since it can mean numerous problems along with the safety risk. If a technician discovers a cracked heat exchanger in a furnace that\u2019s older than 15 years, it\u2019s much more cost-effective to have the furnace replaced rather than just the heat exchanger. A furnace this old doesn\u2019t have many more years of quality service left to it, and you\u2019ll need to replace it soon anyway. If you install a higher efficiency furnace, it will start paying back the replacement cost with better energy performance.<\/p>\n

Replacing the heat exchanger<\/h2>\n

The cost of putting in a new heat exchanger varies depending on the furnace. If you have a younger furnace that might have another decade of service in it, you\u2019ll have to weigh the cost of the heat exchanger replacement against getting a new gas furnace. In general, if the heat exchanger replacement is more than half the cost of a replacement furnace, the new furnace is a better option. Let your HVAC technicians help you make the best choice. If the cracked heat exchanger is a sign of larger problems with a newer furnace (unfortunately a common situation if amateurs installed it), then a replacement is both the more effective solution and the safer one.<\/p>\n
