It's that time of year again! Time to change out your HVAC filter. Most people know they should do it, but many don't know how often they should be changing their filter. In this blog post, we will give you a yearly schedule for changing out your HVAC filter. This way, you can make sure that your system is running as efficiently as possible and prolong the life of your unit!

What Is an HVAC Filter and What Does It Do?

An HVAC filter is a device that helps keep your system clean. It does this by trapping dust, dirt, and other particles from the air. Over time, these particles can build up on the coils of your unit and cause it to run less efficiently. They can also lead to expensive repairs down the road.

Do All HVAC Filters Need to Be Replaced?

No. Not all HVAC filters need to be replaced. The type of filter you need depends on the system you have. If you're not sure what type of filter your unit uses, consult with a professional. You might be able to just clean the filter rather than replace it. However, this usually means more maintenance for you since cleaning is done more frequently than replacement.

How Often Should I Change My HVAC Filter?

The general rule of thumb is to change your filter every six months. However, if you have pets or someone in your home who smokes, you may want to change it more often than that. If you're not sure how often to change it, check with your manufacturer's recommendations or contact a professional HVAC technician.

What Are Signs That My Filter Needs Replacing?

You should keep a regular replacement or cleaning schedule. However, it is a good idea to keep an eye out for signs that it's time for a new filter. The top sign is that it is visibly dirty. This indicates it has done all it can do.

Another sign that it is time for your filter to go is visible damage. This indicates it can no longer perform its job.

Also, check to see if the airflow from your unit is decreased. If you're not sure whether or not your filter needs to be replaced, contact a professional HVAC technician for advice.
