5 Warning Signs of a Dirty Furnace Filter That You Can’t Afford to Ignore

In colder parts of the USA, heating bills can account for between 35% and 50% of energy bills. That’s a lot of money!

When you’re paying that much and depending on the heat, you need to make sure you’re getting the most out of your furnace. That means spotting when the filter may be dirty and getting it swapped out.

However, how do you know when it’s time to change the filter? Here are the signs that you might have a dirty furnace filter.

  1. Higher Bills

If you have a clogged furnace filter, you can expect your heating bills to be higher. If you’re aware of what it usually costs and notice a sudden spike, then it may be time to get that filter looked at.

If you’re wondering why this is, it’s because when the furnace attempts to pull in air, it has to work harder to get through the clog.

You may not have realized a higher bill is one of the signs of a dirty furnace filter, but it’s a big one for that reason.

  1. Dust

If your filter is dirty, chances are, the dust will be circulating around your home as the heater draws it in and disperses it.

If you dust all the time and still can’t seem to get rid of it, it may be because of your furnace filter — especially if in combination with some of these other signs.

  1. Ineffective Heat

Ineffective heat is another sure sign that you might need to replace some furnace filters.

If your furnace is struggling, your house likely isn’t going to heat up as quickly or as well. This can make the colder months very painful, especially in the north of the country!

Following heater maintenance tips is important, as you want the most out of your furnace so you can be comfortable.

  1. You Smell Burning

If your furnace is trying to work through dust and dirt, you may smell an unusual smell — burning.

If this is constant or lingering, it’s important you get it looked at as soon as possible.

  1. You Get Sick

One of the signs and risks of a dirty furnace filter is getting sick. When your furnace is dispersing air around the house that’s full of dirty and of terrible quality, you’re going to be breathing in that air — which, in turn, isn’t good for your body or your immune system.

If you keep getting sick and can’t quite work out how or why then it’s time to take a look at that furnace.

Spot and Change Your Dirty Furnace Filter

If you’re noticing any of these signs, it’s worth having someone look at your potentially dirty furnace filter. They can tell you if it needs to be replaced and if it does, you’ll be healthier, have better heating, and lower energy bills!
