5 Steps of a Furnace Cleaning

When the Chicago winter comes rolling around, your home will be prone to some devastatingly low temperatures. For this reason, you’re going to need your furnace running at its maximum capabilities. 

There are, however, a number of factors which can contribute to a poorly functioning furnace. These need to be negated as soon as possible. Perhaps the most common factor of a poorly functioning furnace is the existence of dust, dirt and grime.

To ensure that your furnace is ready to battle through a harsh winter, you need to get it cleaned.

Looking to clean your furnace by yourself? If so, you’ve come to the right place. These are the 5 steps of a furnace cleaning. 

1. Turn Off the Furnace

The first thing you’re going to need to do when cleaning your furnace is to turn it off. If you’ve got an electric furnace, it’s as simple as flipping off the switch on its exterior. Turning off a gas furnace requires that you twist the valve on the gas line which leads into the furnace.

Don’t, under any circumstances, attempt to clean a furnace while it’s still powered on. This would be unsafe for a number reasons. Not only will your furnace be exceedingly hot, but you will also put yourself at risk of being shocked.

2. Clean the Interior of the Furnace

After your furnace has been turned off, you can begin to clean its interior. This involves unscrewing the cover on the front or back of the furnace and then vacuuming out the dirt in its crevices. You might also want to have a flashlight on hand, as it can often be difficult to see into the intricate parts of the internal machinery.

Make sure to remove any internal component covers so that you can remove every ounce of dirt that you come across. Try your absolute best to get all the way into the back of the furnace.

3. Clear the Furnace Ducts 

Your furnace unit isn’t the only thing that you need clean when cleaning your furnace. You also need to clear out the furnace ducts which lead into the unit.

This process can be a little difficult as well as time-consuming. It requires that you turn on the fan in your HVAC system so that dust can move freely through your ducts. You must then unscrew the ducts so that you can reach inside of them and clear them of any residue.

4. Replace the Furnace Filter

Perhaps the easiest part of any furnace cleaning is the removal and replacement of the furnace filter. Furnace filters are placed in the furnace to catch any large residue which may make its way in. After a while, they will be completely inundated with dust.

Removing a furnace filter is usually as simple as loosening a few screws and pulling out on the filter frame. After it’s been removed, it can be easily replaced with a fresh, new filter.

5. Give it a Test Run

After you’ve replaced the filter, your furnace cleaning will be completed. The only thing left to do now is to turn the furnace back on and make sure that it’s running smoothly.

Listen closely for any rattling noises. These could be screws that you forgot to put back in. If they’re not dealt with, they can get caught up in the machinery of the furnace and cause serious mechanical issues.

And if you don’t trust your own ability to get the job done, you can always call in a professional.
