How much does it cost to replace a heat exchanger in a gas furnace?
Replacing a furnace heat exchanger costs $1,500 on average with a typical range between $1,000 and $2,000. Most have a warranty of 10 to 20 years, which usually only covers the price of the exchanger, which typically ranges from $500 to $2,000. Labor alone runs an average of $500.
What happens when heat exchanger fails?
The problem is that all heat exchangers will eventually fail, developing holes or cracks that allow those poisonous gases to leak out and contaminate your home’s air. These leaks can be extremely dangerous, even deadly. In fact, cracked heat exchangers are one of the major causes of carbon monoxide poisoning in homes.
Will furnace work with cracked heat exchanger?
If it is your heat exchanger, you cannot run your furnace, even if it seems to be running fine. The gases will continue to seep into your home’s air. Many companies, upon finding a cracked heat exchanger, will shut your furnace down so you cannot run it.
How does a heat exchanger work in a furnace?
What Is a Heat Exchanger? The heat exchanger is the furnace component that heats air. It is a set of metal tubes or coils that connects to the burner assembly and ends at the vent or flue pipe. Air and gas are separated within the heat exchanger to prevent mixing and exposure to harmful combustion byproducts, such as carbon monoxide.
What kind of metal is a heat exchanger made out of?
The heat exchanger is manufactured from thin metal, and will be mild carbon steel or stainless steel depending on the type of furnace. Some heat exchangers are a hybrid such as steel with an aluminized coating. During the furnace heating cycle the combustion gas will travel through the heat exchanger and exhaust out of the furnace.
Where does the heated air go in a gas furnace?
A blower motor inside of the furnace blows the heated air into your ductwork from the heat exchanger and is circulated throughout your home. The heat exchanger is a crucial component that makes up gas furnaces.
How long does a heat exchanger usually last?
Heat exchangers offer a typical service life between 10 to 20 years – depending on the life of your furnace and other factors, you may decide to replace the entire furnace if the heat exchanger requires replacement.
What is the heat exchanger in a furnace and how does it work?
A furnace heat exchanger works by literally exchanging (or transferring) the heat created in the combustion chamber to the exterior of the unit, where it is then blown through the ductwork throughout the house.
Should I replace my furnace’s heat exchanger?
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. But if your furnace is no longer under the labor warranty and it’s over 10 years old, you might as well just replace the furnace completely.
Does an electric furnace have a heat exchanger?
Electric furnaces do not use heat exchangers. The way that a gas furnace transitions heat to the air is by collecting high temperature combustion gas inside a metal chamber known as a heat exchanger. The heat from the metal warms up the air passing around it. But electric furnaces heat the air directly using heating elements,…
Is a cracked heat exchanger on a fuel oil furnace dangerous?
In a nutshell, here are some of the dangers of a cracked heat exchanger. Heating your home with natural gas, propane gas, or fuel oil can result in the leakage of harmful gases when the heat exchanger cracks. Fossil fuel gases like Carbon Monoxide Poisoning Serious tissue damage caused by carbon monoxide building up in the bloodstream. and carbon dioxide can cause several health issues.
