Can a furnace heat exchanger be repaired.

How to determine if a furnace has a cracked heat exchanger most problems with a gas furnace can be repaired though the repair cost is not always justified. This doesn t require replacing other parts of the furnace. Our friendly professional technicians are ready to help. Pour a little bit of the chemical on the hole and leave it to dry until it seals around the exchanger.

Check your documentation or contact the installer to find out. While we don t really repair cracked heat exchangers it s sometimes possible to replace them without replacing your entire furnace. A furnace with a cracked heat exchanger is usually an exception because of the cost of the repair. Occasionally cracked heat exchangers cause the flame to roll out and trip the safety switch shutting off your furnace.

If your furnace is no longer under warranty the decision becomes a little more difficult. Most repairs require a component that will return the furnace to normal and safe operation. Most furnace installers offer a labor warranty that lasts anywhere from 1 to 5 years after they installed the unit. Electric furnaces do not have a heat exchanger.

If the furnace is 10 years old or newer it s likely under some sort of protection agreement. So if your furnace is still under its labor warranty we definitely recommend replacing just the heat exchanger since most of the repair cost will be covered under warranty. So the first thing to do is to check your furnace s warranty. Press this onto the furnace heat exchanger and allow it to dry.

However it s an expensive repair. When a gas furnace heat exchanger fails not only is it dangerous and can result in carbon monoxide poisoning the heat exchanger replacement cost is usually on the high side of typical furnace repair costs. The furnace heat exchanger is the one of the main components inside the gas furnace and it s used to transfer the heat from the gas burner to the warm air that s blown into your home. The best way to repair a cracked heat exchanger is to remove it and put in a new one.

It s possible to repair a cracked heat exchanger but the repair is a costly one. And because it can take up to 8 hours or longer to replace a heat exchanger the labor itself is the bulk of the repair cost. Weld the sheet metal some more as it dries. A typical furnace will last about 20 to 25 years.
