Here is some information on heat exchangers, some of the reasons they encounter problems, and what you should do if you spot something wrong.
Heat Exchangers in Hanover Park, IL
The heat exchanger separates air used in the combustion process from the air that you breathe inside your home. It is typically a metal chamber that begins at the burner assembly and stops near the chimney vent and furnace connect. As air moves across the heat exchangers hot metal surface it is warmed and then distributed through your home.
It is imperative that your heat exchanger is sealed tightly, because if gases from the flue are allowed into your breathing air, carbon monoxide poisoning is a distinct possibility.
Reasons for Heat Exchanger Failure in Hanover Park, IL
Eventually, metal fatigue will lead to a heat exchanger failure. Metal expands when heated and contracts when it cools off. This constant movement will result in a breakage for the same reason that a paper clip will eventually break when it is moved back and forth. Most heat exchangers normally last between 10 and 20 years, but if they are poorly designed, installed or maintained, their lifespan can be substantially reduced.
Signs of Heat Exchanger Failure in Hanover Park, IL
Typically, the only way that you can spot a heat exchanger problem is by looking for some sort of breach, such as light or water passing through a crack or a hole. At Approved Comfort, we use sophisticated infrared video inspection devices to thoroughly examine every inch of a heat exchanger this is far superior to the old method of using a flashlight and a mirror.
Many people assume that testing for carbon monoxide will expose a heat exchanger problem, but the exchanger can still be breached even if a furnace is not producing the toxic substance.
What to do if Your Heat Exchanger Fails in Hanover Park, IL
Unfortunately, you basically have only two options if your heat exchanger is bad either replace the exchanger or replace the furnace. The first option is preferable if it is still under warranty; however, if an exchanger is not available quickly and the weather is cold, you may simply need a completely new furnace. A new furnace may be the better option if the cost of replacing the heat exchanger is comparable to a system replacement.
Call Approved Comfort and one of our professionals will come to your home, perform a thorough analysis of your heat exchanger and the rest of your furnace, and completely spell out all of your potential options.
