How to Know when it is Time to Change your Air Filter

The air filter is one of the most important parts of a central air conditioner. It helps keep the air free from dust and other allergens as they are pulled in from the outside. Some homeowners neglect this important piece of equipment and don’t bother checking to see if it is time to clean or replace your filter. This is a bad idea, as it makes people with allergies susceptible to illness and makes your unit work much harder than it needs to.

Most people choose to replace their filters instead of trying to clean them. They are relatively inexpensive and can be purchased at any hardware store. It is essential that the replacement filter be the correct size for your unit, so you may want to write down the type of filter you have before going out and buying a new one. Generally speaking, you should look to buy a new air filter every two months depending on how much usage your unit is getting. During the peak summer months, it may be wise to change it monthly.

It may be a good idea to check your air filter to ensure it is in good condition for the spring and summer. Most homeowners haven’t been running their unit during the winter months, but it is still possible for dust to gather on the filter. To make sure that your filter is ready for the coming season, consult your unit’s instruction manual and check your air filter today.

Along with changing your air filter, it may be a good idea to have your air conditioner inspected before we get into the dog days of summer. Because St. Louis summers are so hot and humid, our air conditioners will get quite a workout. Having routine maintenance performed can not only keep your unit in better shape for longer, but it can also cut down on energy bills during these summer months, potentially saving you hundreds of dollars.
