Your air conditioning unit plays a key role in keeping your home comfortable, yet many homeowners overlook a straightforward but essential maintenance task: cleaning the AC filter. At Westerville Air Conditioning & Heating, we understand the significance of fresh air and efficient cooling. Here’s why cleaning your air conditioner filter matters for health and the HVAC system, along with a step-by-step cleaning guide.
The Importance of a Clean Air Conditioner Filter

Not sure when to change your HVAC filter? If it’s been more than a month, it might be time. Most should be swapped out every 30–60 days based on home size, pet hair, and lifestyle. Check out the EPA’s Guide to Air Cleaners for pro tips on cleaner indoor air.
Clean air filters help with the following:
1. Improved Air Quality
An AC filter’s main job is to capture dust, pollen, and airborne particles. As these accumulate, a dirty filter becomes less effective, allowing pollutants to re-enter your home and potentially exacerbating allergies and respiratory issues.
2. Boosted Energy Efficiency
When clogged, your air conditioner has to exert extra effort to move air, consuming more energy and raising utility bills. A clean filter ensures smoother airflow, enhancing energy efficiency and cutting costs.
3. Extended System Life
A filter that’s regularly maintained helps keep your AC running smoothly, preventing unnecessary wear and tear. This leads to lower repair costs and a longer lifespan for the unit.
4. Superior Cooling Performance
A clean filter allows for free and even airflow, helping your AC cool your home effectively, which provides consistent comfort during the hottest months.
Steps to Clean Your Air Conditioner Filter

Cleaning your air conditioner filter is a task you can handle on your own without needing professional services. Here’s how:
1. Power Down the Unit
Always start by turning off your air conditioner. Do this either on the unit itself or at the circuit breaker to ensure your safety.
2. Remove the Filter
The filter is generally found behind the front panel or within the air handler. Gently take off the panel and slide out the filter. If you’re having trouble locating it, refer to your AC manual or reach out to Westerville Air Conditioning & Heating for help.
3. Inspect the Filter
Check if the filter needs cleaning or replacement. Disposable filters should be changed when worn, while reusable ones can be cleaned multiple times before replacement is necessary.
4. Clean the Filter
If the filter is reusable, follow these steps:
- Vacuum: Use a vacuum cleaner with a soft brush to clear loose dust from both sides of the filter.
- Wash: Soak the filter in warm water mixed with a few drops of mild dish soap. Use a soft brush to gently scrub off remaining dirt. Steer clear of harsh chemicals and high-pressure water.
- Rinse and Dry: Rinse with clean water and allow it to air dry fully to prevent mold growth.
5. Reinstall the Filter
Once dry, place the filter back into its slot and secure the cover. Restore power and verify that the AC is working properly.
How Often to Clean or Replace Your Air Conditioner Filter
As mentioned above, the frequency for cleaning or replacing your AC filter depends on several factors. Here’s a deeper look into that:
- Usage: During high-use periods, such as summer, aim to clean or replace the filter monthly.
- Local Air Quality: If you reside in a dusty or pollen-rich area, more frequent cleaning may be necessary.
- Household Dynamics: Larger households or those with pets might experience increased particle accumulation, necessitating more frequent maintenance.
