Air Filter Replacement Services

The air filter plays an essential role in your home’s HVAC system. The HVAC filter traps debris and prevents it from getting inside the system, where it could damage sensitive components. However, the filter can get clogged over time.

This may force the system to use more energy when cooling or heating your home. The result? High energy bills, and an HVAC unit that’s more likely to break down prematurely. That’s why it’s essential to change the filter regularly.

What You Need to Know About Replacing an AC Filter

Typically, a homeowner should perform an air filter replacement at least once every three months. That said, various factors can impact how often you should replace yours. Environmental conditions, the size of your system, how often you run it, and even the age of your HVAC unit are all factors you must consider.

Thus, it’s smart to coordinate with professionals. Ask them to demonstrate how to replace the filter, and ask them how often you need to do so.

The process typically involves these essential steps:

Finding the Return Air Intake

First, find the return air intake. An HVAC specialist can help you locate this component if you’re not sure where it is. Open the door, and take note of what size filter the system uses.

Keep in mind, some homes have numerous return air intakes with multiple filters. These air filters won’t always be the same size. Check all of them before buying new ones.

Purchasing Filters

You can find home air conditioner filters at many hardware stores and big box stores with hardware departments. Some newer models are designed to function reliably for longer periods of time than most. Again, an air filter replacement expert can recommend the ideal one for your needs.


Replacing the filter is usually a fairly simple process. Just open the return air intakes, remove the old filters, and install the new ones. Usually there will be arrows on top of the filter indicating which direction it should point in when you install it.

Why Regular Air Filter Replacement is Essential

If you don’t replace your HVAC filter on a regular basis, your system is more likely to sustain damage and run inefficiently. In fact, not replacing the filter regularly can impact the wellbeing of every member of the household. Here are just some of the problems that can develop if you don’t change your filter according to schedule:


Clogged filters that are exposed to condensation can result in mold growth. Mold in your HVAC system is a particularly serious problem. The air from the system can often distribute mold spores throughout your home.

If any member of the household is allergic to mold, the health consequences may be serious.

High Energy Bills

Systems that run inefficiently due to clogged filters can dramatically increase your energy bills. Simply replacing them according to schedule is an easy way to avoid paying more than you have to.

It’s also better for the environment.

Frequent Breakdowns

Using a lot of energy to compensate for a clogged air filter puts your HVAC system through wear and tear. As a result, it’s more likely to stop working without warning. Obviously, this is a problem you want to avoid. No one wants the air conditioner to break down in the middle of a heat wave.
