An air conditioner filter is one of the least expensive and most easily replaced pieces in your HVAC unit, but it’s also very easy to ignore. Just because your filter isn’t as noticeable as other items that might need your attention, it’s still important. In fact, properly caring for your air filter can save you money on your electricity bill, and maybe even on an HVAC contractor down the line. The following is a guide to AC filters—what they are and how they’re maintained.

What Is an HVAC Air Filter?

The air filter sits in your HVAC system, allowing all outside and recycled air to pass through it before the air goes through your heating/cooling system. As the air moves through, the filter picks up debris of various sizes depending on the type of filter you have. Pet hair and dirt from inside the home are commonly found in air filters, so the dirtier your home is, the quicker the filter gets full of debris. If your air filter is not working properly, your HVAC system will need to work harder to provide proper air flow in your home.

How Do I Know If I Need To Change My Air Filter?

A plugged up air filter will stop providing a healthy environment for your family. If you notice reduced air-flow, or an unexplained increase in your electric bill, you might need to change your filter. If you have several animals or long-haired pets, you should also check the filter more often by going to your HVAC unit and pulling out the filter. If it’s dirty, you should replace it with a new one. A typical air filter should be replaced around every 3-6 months.

How Do I Replace My Air Filter?

Most air filters can be replaced without the help of an HVAC contractor. Some filters can be cleaned with a water, but most are just thrown away. Check your HVAC user manual for details relating to your specific unit, or contact an HVAC contractor if you need additional help.
