Signs That Your Furnace Is about to Shut Down

Posted on

When your home's furnace shuts down completely, of course you need to call a contractor and have it repaired, but often there are signs that the unit is in need of repairs long before it actually breaks. Being aware of these signs can help a homeowner to know when they should repair their furnace and will help avoid even costlier repair bills down the road. If you notice any of the following in your own home, call a contractor right away.

1. Overly loud or unusual sounds

A furnace may make a humming or whooshing sound when it first comes on, but if you notice any overly loud or unusual sounds coming from your unit, you may need to call for repairs. This is often a sign that there is a part that is coming loose or that one part is grinding against another. As the motor or fan breaks down they may also start to creak and groan and this sound is carried through the vents.

Having these sounds checked out as soon as you notice them can keep broken parts from doing more damage and in turn, you can avoid larger repair bills down the road.

2. Burning smells

In some cases you might notice a burning or charred odor coming from your vents and this can be the dust and other debris that build up inside your ductwork. As the warm and dry air of your furnace passes over this dust, it can actually get singed. In other cases a burning smell can mean that the motor or fan is breaking down or that parts are grinding against another.

Ignoring any of these problems can allow your furnace to shut down, as having to push air through very dirty vents puts excess wear on the unit. Letting parts grind against each other can also allow them to completely break down or simply break off.

3. Uneven or very poor heating in your home

Your furnace should work to push warm air through all the vents in your home so that rooms are heated evenly. If it doesn't do this, it may be struggling with a faulty motor or blower. You may also need a new thermostat to help control the heat output. If this problem is ignored the furnace can be working too hard to push out warm air and this wear and tear can cause it to break down very quickly.
