Cleaning Your AC Air Filter and Why It’s Essential

Have you inspected your air conditioner filter? As a rule of thumb, you should inspect it each month and take the appropriate steps when it looks dirty. We’ll share details about the different types of AC filters, why they require regular upkeep and step-by-step instructions on how to clean reusable filters effectively.

The Available Types of AC Filters

Your filter choice impacts indoor air quality, airflow efficiency and whether you should clean or change it when it becomes worn down or clogged. Here’s a summary of some common options:

• Disposable filters are usually made from fiberglass and a paper frame. These filters are intended for short-term use and should be swapped out every one to three months. They are typically inexpensive and quick to put in but not as environmentally friendly because they need to be thrown out.
• Reusable filters have stronger frame materials made with metals like aluminum or plastic. These filters can be cleaned and reused multiple times, and can last many years if cared for properly. They are more environmentally friendly and affordable in the long run. But on the downside, washing them takes extra time and effort than simply replacing a disposable filter.
• Electrostatic filters utilize static electricity to capture particles efficiently while maintaining airflow. These can be both disposable or reusable. Reusable electrostatic filters require regular washing to preserve their effectiveness.
• HEPA filters, or high-efficiency particulate air filters, are the top filters of all, removing 99.97% of airborne particles down to 0.3 microns. The bulk of HEPA filters are single use, but they remain effective for up to one year before needing to be replaced. While they offer exceptional filtration, they are costlier and aren’t always compatible with all HVAC systems.

Why Should You Wash or Replace Your AC Filter? 4 Important Reasons

It’s an easy chore to overlook, but rinsing or replacing your AC filter is a key part of overall system maintenance for several reasons:

1. Better air quality: A new filter captures dust, pollen, pet dander and other pollutants, keeping your indoor air cleaner and healthier. This plus is particularly important for people with allergies, asthma or other health issues.

• Energy efficiency: If you never wash or change your filter, the dust and debris slowly filling it it forces the AC to work even harder. A fresh filter preserves airflow, lowering the unit’s workload and helping rein in your energy bills.

• Prolonging your equipment’s life span: Regularly washing the filter stops the system from overheating, decreases wear and tear, and can even prolong your unit’s lifespan!

• Saving money on energy bills and early replacement: A clean filter reduces costs by cutting your energy bills, limiting damage and minimizing the risk of early replacement for the AC.

A Step-by-Step Guide to Washing Your AC Filter

Follow these steps every one to three months to get all the benefits of a clean air filter:

Prepare: First, shut off the AC unit to avoid electrical fire or similar hazards. Then, access your AC filter. It will most likely be found in the return air duct, in the air handler cabinet or within the unit itself.

Remove the filter: Gently remove the filter from its housing. Examine for holes or tears. If the filter is ripped, go ahead and change it.

Vacuum the filter: Get the brush accessory on your vacuum cleaner to remove dirt, hair, fibers and other loose debris.

Wash the filter: Bring the filter outdoors and rinse it off with a garden hose. For a more thorough clean, apply a mild detergent.

Dry the filter: Leave the filter out to dry on its own completely before putting it back. In the meantime, remember to not turn on your air conditioner or you risk bringing more dust particles inside the unit.

It’s important to note that disposable filters aren’t washable. They need to be swapped out when they become too clogged up with debris. The replacement filter should be the same size and type to make sure there’s compatibility with your AC unit.

Other Elements of an AC Unit to Maintain

Besides the air filter, additional AC components need routine upkeep for optimal results and longevity. Reach out to an HVAC contractor for help maintaining the following:

• The evaporator coils inside the air handler remove heat from the air. After enough time, these coils gather a lot of dust, which lowers heat transfer efficiency. HVAC Experts apply a specific cleaning solution to clear away dust and grime.
• The condenser coils within the outdoor system exhaust the heat taken out of your house. These coils are exposed to the rain and snow, and can get dirty fast. While you can lightly rinse off dirt, leaves and other debris using a garden hose, leave more in-depth seasonal cleanings to a professional.
• The fan blades in your AC unit will also accumulate dust and dirt. An HVAC professional will inspect the fan as part of their yearly tune-up, cleaning and adjusting the blades as necessary to restore normal performance.
• The condensate drain line in your AC unit can become clogged up with algae, mold and debris. Should this happen, call a qualified contractor to clean the drain line using a strong cleaning solution or mold treatment.
