How to Clean Your AC Filters in 5 Easy Steps

AC Filter Cleaning in Burbank, CA

Your HVAC system’s filters play a vital role in keeping the air inside your home clean by trapping dirt, pollen, pet dander, and other small particles. Over time, these filters collect debris and become less effective, which can impact your indoor air quality and system performance.

Signs It’s Time to Check or Clean Your AC Filters

  • Increased dust buildup in your home

  • Allergy-like symptoms such as sneezing or congestion

  • Reduced airflow from vents

  • Higher electricity bills

  • Strange noises from your AC unit (working harder)

  • Uneven temperatures throughout your home

  • Your AC runs more frequently to maintain set temperature

  • Mold growth on bathroom walls, window sills, or fabrics

Types of AC Filters: Permanent vs. Disposable

  • Permanent filters can be cleaned and reused.

  • Disposable filters are not designed for washing and degrade if cleaned with water or vacuumed aggressively. Cleaning disposable filters is only a short-term fix until you replace them.

  • Wet or damp disposable filters can promote mold growth, so be cautious.

Benefits of Cleaning Your AC Filters

  • Saves money on energy bills by reducing system strain

  • Maintains better indoor air quality and reduces allergens

  • Helps protect vulnerable family members (children, elderly, people with respiratory issues)

  • Prevents dust circulation and buildup on furniture

  • Extends the life of your HVAC system

How to Clean Your AC Filter in 5 Easy Steps

  1. Turn off the AC
    Use the thermostat “off” setting to prevent dust from circulating while cleaning.

  2. Remove the filter
    Open the vented cover (usually with a screwdriver) and gently take out the filter. Consult your manual or contact Air Max HVAC for assistance.

  3. Vacuum off superficial dust
    Use a vacuum cleaner with a brush attachment to remove loose dirt gently. Avoid pressing hard on the filter.

  4. Rinse the filter
    For heavily soiled filters, soak in a 1:1 mixture of vinegar and water for about an hour, then rinse with clean water and let air dry completely. For larger filters, use a garden hose and spray with the vinegar solution, then rinse thoroughly. Never reinstall a damp filter.

  5. Reinstall the filter
    Place the dry filter back in the correct orientation (follow arrow markings) and secure the cover.

When Should You Replace Your AC Filters?

  • Follow the manufacturer’s recommendation—usually every 3, 6, or 12 months.

  • Replace more frequently during heavy pollen seasons, wildfire smoke events, or other situations with high airborne particles.

  • HEPA filters generally last longer but still need periodic replacement.

Recommended Routine HVAC Maintenance

To keep your system running efficiently year-round, schedule professional maintenance twice a year (spring and fall are ideal). Maintenance covers:

  • Electrical components

  • Lubricants and refrigerant levels

  • Mechanical inspections
