What is a Heat Exchanger and What Can Go Wrong With It?

cold-man-thermostat-handsWearing layers is a great way to stay warm outside and at home. However, when you step into your house it is nice to be able to enjoy taking off a layer or two and remaining comfortable. When you need a heater repair in Fruitland, NM though you are likely to discover that you need just as many layers indoors and you do when you are outside. That’s not normal!

Those residents that use gas-powered furnaces in our area should take note when their heater doesn’t seem to be able to do its job. The solution may be a simple one like a thermostat that needs to be reset. However, it can also be something more serious like an issue with your heat exchanger.

What is a Heat Exchanger?

We want to start here for good reason. No, we don’t expect you to be an expert on the inner workings of your furnace (we’ve got that covered, not to worry.) However, we have found it helps residents around her to know how their furnace works because it helps them contact us that much faster when things aren’t working the way they should.

With that said, let us give you a quick rundown on the role of your heat exchanger.

When your furnace burns gas, this creates what’s known as combustion gases. These gases flow into your heat exchanger. The exchanger is a metal, sometimes clam-shaped, structure that holds those gases and heats up. As the metal heats up it will warm the air that is around it which is then blown into your home. Voila, you have hot air thanks to your heat exchanger. This is a pretty vital part of your furnace that you want to keep in optimal condition.

What Can Go Wrong With Your Heat Exchanger

Your heat exchanger is filled with combustion gases that heat it up. When metal warms up, it expands. This isn’t a problem unless you have a cracked heat exchanger.

A cracked heat exchanger is a problem for two key reasons. The first reason is that when gas escapes from that crack it slows down the creation of heat, hindering the ability of your furnace to warm your home. Secondly, that is gas that is leaking out of your system and into your home; this is of course a dangerous situation as it can put your health and the health of others in the house at risk. If your furnace’s heat exchanger develops a crack, you need to get it repaired as quickly as possible to keep your home safe and comfy.

Furnaces are made to operate safely but when your system gets too old or falls into disrepair, issues like a cracked heat exchanger can pop up that put your health and your comfort at risk. Avoid these issues by relying on a professional for your heating system services, maintenance included!
