7 Problems Caused By a Dirty HVAC Filter

March 20, 2023

Around 82% of Americans forget to change their HVAC filters every month. Are you a part of that 82%?

Having a dirty HVAC filter may not seem like a huge issue. You may have more pressing matters to deal with, but there are several problems that can arise if you forget to change them.

Not many people talk about the importance of HVAC care, but we are here to change that. It's vital that you are educated and understand the warning signs of a dirty HVAC filter.

All the information below will help you keep your home clean, safe, and comfortable. Continue reading so you can keep your household running smoothly.

1. High Energy Bill

It's normal for your electric bill to fluctuate throughout the year. However, it will be even higher if you don't clean and change the filters.

The more build-up there is, the harder your HVAC system has to work. The more energy that is required to cool your house, the more expensive it will be.

You may not see a spike in your bill, but it will gradually increase over time. To avoid this, be sure to check your bill every month and make a note of any changes.

During the winter, your system has to work a little harder. It will be beneficial to change the filters in your HVAC unit more often in the cooler months.

2. Poor Air Quality

Poor air quality in your home is an issue that you want to avoid at all costs. Dirty filters will become clogged and allow unwanted particles to circulate throughout your house.

Pollen, dirt, and dust can cause respiratory issues and even allergies, which is the last thing you want. Poor air quality isn't as easily identifiable as some of the other problems.

You may not notice that the air in your home is contaminated until it's already affecting your health. This is why it's crucial that you don't let the filters in your HVAC system get dirty.

3. Frequent Breakdowns

Another issue that will arise if you have a dirty HVAC filter is frequent breakdowns. Clogged filters and blockages will cause a lot of damage to your system. If you start to notice that your HVAC system is needing repairs more frequently, start by checking the filters.

In the hot summers, you don't want your HVAC system cutting out on you. Aside from it being inconvenient, it's also very expensive. Instead of paying for repairs every few months, have some extra filters on hand so you can change them regularly and on time.

4. Unpleasant Odors

Over time mold and bacteria can grow in your dirty HVAC filters. This can cause your home to smell.

As soon as you notice a musty or stale odor, check your filters. Life gets busy sometimes and it can be easy to forget about your HVAC system, especially if it's been working as normal.

The good news is that the strange odor coming from your system isn't a huge issue. Once you change your filters, the smell will likely go away in a few days, so don't worry.

5. Shorten Life Span

Your HVAC system is an investment and as a homeowner, you want your system to last as long as possible. Replacing your unit after only a few years is not ideal as they are expensive.

In order to prolong your system's lifespan, you'll need to prioritize filter replacement and HVAC maintenance. If your unit is always working harder than necessary, it won't last as long.

Purchasing filters every few months is going to be much more affordable than replacing your entire system prematurely. One of the best tips that we share with homeowners is to mark your calendars, so you never forget when it's time to replace your filters.

We also suggest that you set a reminder so you know when it's time to order more filters. If you forget to order filters, you'll have to wait even longer to switch them out, putting more strain on your system.

6. Uneven Heating and Cooling

Another tell-tell sign that your filters are clogged is even heating and cooling throughout your house. Some rooms may feel cooler than others, which isn't ideal for your comfort.

The dust in the filters will cause airflow to be constricted in some areas. Before calling a professional, check your filters—they are likely the issue. You'll notice a significant difference in the airflow once you have a new, clean filter installed.

Replacing your filter shouldn't take too long. It's a simple task that makes a huge difference.

7. Increased Risk of Fire

Your home should be a safe place for you and your family. If your HVAC filters are constantly dirty and clogged, your home is no longer as safe as it should be.

Dust and other debris can be extremely flammable. Changing your filters on a regular schedule will reduce the risk of fire igniting in your home.
