Maintaining the HVAC Air Filter and Why It’s Important

When was the last time you checked your air conditioner filter? As standard practice, you should examine it each month and take the appropriate steps when it looks dirty. Find out what you should know about the different types of AC filters, why they need regular maintenance and detailed instructions on how to clean and replace reusable filters correctly.

The Available Types of AC Filters

Your filter design affects indoor air quality, ventilation efficiency and whether you should wash or replace it when it becomes dirty. Here’s an overview of some of the most common options:

• Disposable filters are usually made using fiberglass along with a paper frame. These filters are intended for short-term use and should be replaced every 1 to 3 months. They are usually inexpensive and quick to replace but not as environmentally friendly since they need to be thrown out.
• Reusable filters have more durable frame materials made with metals like aluminum or plastic. These filters can be rinsed out and reused again, often lasting many years if cared for properly. They are more environmentally friendly and cost effective in the long run. That being said, cleaning them takes additional time and effort than simply changing a disposable model.
• Electrostatic filters use static electricity to trap pollutants quickly while preserving airflow. These can be designed to either be disposable or reusable. Reusable electrostatic filters will need regular upkeep to preserve their effectiveness.
• HEPA filters, or high-efficiency particulate air filters, are the best filters for residential needs, trapping 99.97% of airborne particles down to 0.3 microns. Most HEPA filters are disposable, but they can be used for up to one year before needing to be replaced. While they provide superior filtration, they are higher priced and aren’t compatible with all HVAC systems.

Why Should You Wash or Change the AC Filter? 4 Important Reasons

It’s a simple chore to ignore, but washing or replacing your AC filter is important for a few reasons:

1. Enhanced air quality: A clean filter is more effective at trapping dust, pollen, pet dander and other particles, keeping your indoor air fresher and healthier. This kind of full spectrum comfort is particularly important for people with allergies, asthma or other respiratory conditions.

• Use energy more efficiently: If you never clean or swap out your filter, the dust and debris clogging it causes the AC to strain even more. A fresh filter preserves airflow, lowering the unit’s workload and helping to manage your energy bills.

• Longer life span: Regularly cleaning the filter stops the system from overheating, lowers wear and tear, and can even lengthen your unit’s lifespan!

• Saving money on energy bills and early replacement: A new filter reduces costs by tightening up your energy bills, avoiding damage and minimizing the risk of early replacement for the AC.

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

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

Prepare: To start, power down the AC system to prevent electrical fire or similar hazards. Then, access your AC filter. It might be in the return air duct, in the air handler cabinet or inside of the unit itself.

Remove the filter: Slowly remove the filter from its slot. Check 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 get rid of dirt, hair, fibers and other particles.

Wash the filter: Take the filter outdoors and rinse it off with a garden hose. For a filter that’s as clean as possible, add a small amount of a mild detergent.

Dry the filter: Lay the filter out to air dry completely before putting it back. In the meantime, do not use your air conditioner or you risk allowing more dust particles inside.

It’s important to note that disposable filters cannot be washed. They should always be swapped out when they become clogged with dust. The replacement filter should be the same size and type to make sure there’s compatibility with your AC unit.

Other Elements of an Air Conditioning System to Clean

Along with the air filter, additional AC components should receive routine upkeep for peak performance and longevity. Reach out to an HVAC professional for help servicing the following:

• The evaporator coils located in the indoor system remove heat from the air. With use, these coils collect a lot of dust, which restricts heat transfer efficiency. HVAC Experts use a specific coil cleaner to eliminate dust and grime.
• The condenser coils found in the part of the unit kept outside release heat absorbed from your home. These coils are left out in the rain and snow, and become dirty quickly. While you can lightly wash away dirt, leaves and other debris by grabbing a garden hose, leave more in-depth seasonal servicing to a professional.
• The fan blades in your AC system’s blower will also gather dust and dirt. An HVAC contractor will examine the fan as part of an annual tune-up, cleaning and tightening the blades as necessary to restore regular performance.
• The condensate drain line in your AC unit can get clogged up with algae, mold and debris. If this happens, call a qualified contractor to clear the drain line using a strong cleaning solution or algaecide.
