Maintaining Your Furnace Filter: Common Problems and Solutions

Having a functioning furnace filter is essential for keeping your home's air clean and free from allergens. However, over time, these filters can become clogged or damaged, leading to a variety of problems. In this article, we'll discuss the most common furnace filter issues and how to fix them.

Clogged Filters

One of the most frequent issues with furnace filters is clogging. This happens when dirt, dust, and other debris accumulate in the filter, reducing airflow and making it difficult for your furnace to do its job properly. Clogged filters can cause your furnace to work harder than it should, resulting in increased energy costs as well as potential damage to your system.

To prevent clogged filters from occurring in the first place, you should change them regularly according to the manufacturer's instructions. If you live in an area with high levels of dust or pollen particles in the air then you may need to change your filter more often than usual.

If you notice that your filter is already clogged then it's important that you replace it immediately. Make sure that you follow all instructions carefully when installing a new one.

Damaged Filters

Another common problem with furnace filters is damage caused by incorrect installation or lack of regular replacement. Damage can also occur if the filter is exposed to extreme temperatures or humidity levels.

If you notice any signs of damage on your existing filter then make sure that you replace it right away. Be sure to follow all manufacturer instructions when installing a new one too.

Incorrect Size

Another issue that can arise with furnace filters is incorrect sizing. If your filter isn't sized correctly for your particular system then it won't be able to do its job properly which could lead to decreased efficiency as well as increased energy costs.

To make sure that you have the correct size filter for your system, check out the manufacturer's specifications before purchasing a new one. You should also measure up the existing one so that there are no surprises when fitting a replacement.

Wrong Type of Filter

Finally, another common problem with furnace filters is using an unsuitable type for what's required. Different types are designed for different purposes such as removing particulates like dust and pollen or odors and chemicals, so make sure that yours fits what's needed.

To ensure that you're using an appropriate type, consult either your owner’s manual or contact an HVAC technician who will be able to advise on which type would best suit.

Conclusion

Furnace filters play an important role in keeping our homes' air clean, but they can become clogged, damaged, incorrectly sized, or even just not suitable over time. To prevent these problems from occurring, be sure to inspect them regularly, replace them according to manufacturer instructions, check their size before purchase, and use only those types suitable for purpose.
