Every homeowner in Archdale, North Carolina, should know how to change their air conditioner filter. It’s a basic bit of maintenance that can boost the efficiency of your AC unit and save you a considerable amount of energy and money. Know when your air conditioner filter is due for replacement, and keep the following aspects in mind while changing it.

How Often Should You Change the Air Conditioner Filter?

The life span of your AC filter depends upon various factors, like the type of filter, quality of indoor air, and how often you run your AC. Some homeowners prefer to change the air filter periodically, such as once a month, while others may change it as soon as the summer sets in.

There is no hard and fast rule as to how often you should replace your HVAC filter because so many factors can affect this decision. You should replace the filter when it gets dirty. You will have to change it more often if your home is located in a construction zone, if there are pets in the house, or if any of your family members suffer from asthma or allergies.

Ideally, check the filter every month, at least in the summer, in order to determine whether it needs a replacement.

Choose the Right Type of Filter

Air conditioner filters today come in several different varieties. Make sure you know which kind you need.

Fiberglass filters are the most common type. They usually require replacement once a month. A pleated filter, on the other hand, is more effective in removing air pollutants and can last for about three months. If you are looking for something still more efficient, consider buying an electronic filter — it uses electricity to attract and remove even the smallest amount of smoke, odors, and other pollutants.

Electrostatic filters, on the other hand, use static energy to charge the air and attract the pollutants. However, they are inefficient in removing bacteria, odor, and other smaller particles, and that may create health issues for your family.

Size and Compatibility

The size of an air filter will be printed on the label. Even if you don’t see any size mentioned, you can measure the dimensions of the old filter or even take the old filter with you, as a sample, when buying a new one.

HVAC filters are rated on a scale of one to 20 based upon their Minimum Efficiency Reporting Value (MERV). A filter with high MERV will remove more pollutants from the air. Usually, the higher the efficiency, the tinier the filter pores will be, which will restrict the inflow of air into the air conditioner. In order to avoid this situation, you should ensure that the new filter you buy matches your machine’s blower’s capacity and is compatible with the whole air conditioning system.

Switch Off the AC

Before you begin removing the filter, make sure you’ve switched off the air conditioner. This is important for your own safety as well as for preventing dust from getting into the unit. If you allow the AC unit to run while removing the filter, it will pull in the dust particles from the old filter and the room air after the filter is removed.

There are multiple switches in your AC system; to be on the safer side, switch off from the main button that supplies power to the entire unit.

Consider the Airflow Direction

An arrow symbol on the filter shows the direction of airflow. Make sure you put the filter such that the airflow arrow points in the correct direction. The filter should also fit into its slot properly so that no air leaks into the system from anywhere around the filter frame. If you notice any loose fitting, use a piece of cloth or tape to take care of the leakage.
