Dirty air filters or clogged air filters greatly impact the quality of your air conditioner’s performance. In order to keep your AC unit cycling clean, cool air throughout your home, you need to maintain clean air filters by cleaning or changing them every one to three months, depending on how often you run your unit.
Frequently changing your air filter prevents dirt and air pollutants from entering your home, preserving you and your family’s health. In addition, a clean air filter will keep your unit running efficiently by improving the unit’s air flow. In fact, the United States Department of Energy reports that a clean filter can lower your air conditioner’s energy consumption by five to 15 percent.
Before attempting to change your AC filter, make sure the air conditioner is shut off and even unplugged. To change the air filter on a central AC unit, you must first locate your filter. You can usually find it on the return duct, near the wall, ceiling or furnace. You can generally remove the filter by sliding it out or pulling it towards you. If you have a window AC unit, you can usually find the filter mounted in the grill facing the room.
If you plan to clean the existing filter, you can do so by vacuuming it off and washing it with hot water and dish detergent. Before replacing the filter, you should check the grill, fins and coils for dust and dirt as well and vacuum them off. On a window unit, you can vacuum the grill and inside of the unit. Check your air filter to see if it specifies a direction for air flow, and insert it back into the unit facing that direction.
If you plan to replace the existing filter, check the filter for its measurements so you know what size to replace it with. After purchasing a filter, write the date on the filter so you know when you replaced it. Check your air filter to see if it specifies a direction for air flow, and insert it back into the unit facing that direction.
If you’ve replaced your air filters and your unit is still not operating properly, a larger technical problem could exist. Contact All Seasons Heating & Cooling for Baltimore air conditioning repair services.
