Follow These Steps to Clean Your AC Filter
How long has it been since you looked at your air conditioner filter? As a rule of thumb, you should check it once a month and clean or replace it when it is dirty. Find out what you should know about the multiple types of AC filters, why they require regular care and detailed instructions on how to wash reusable filters properly.
Why Should You Wash or Change the AC Filter? 4 Reasons Why
It’s a simple chore to overlook, but washing or changing your AC filter is a key part of overall system maintenance for several reasons:
1. Saving Money
A new filter saves money by tightening up your energy bills, preventing damage and minimizing the risk of early replacement for the AC.
2. Energy Efficiency
If you never clean or change your filter, the dust and debris slowly filling it it forces the AC to exert even more energy. A fresh filter optimizes airflow, lowering the unit’s workload and helping to manage your energy bills.
3. Improved Air Quality
A clean filter traps dust, pollen, pet dander and other particles, keeping your indoor air cleaner and safer. This kind of full spectrum comfort is particularly crucial for people with allergies, asthma or other health issues.
4. Prolonging Your Equipment’s Life Span
Regularly washing the filter stops the system from overheating, lowers wear and tear, and can even lengthen your unit’s life span!
Instructions for Cleaning Your AC Filter
Before you go grab the filter, it’s important to note first that disposable filters aren’t washable. They must be thrown away once they become too clogged up with debris. The replacement filter should be the same size and type to ensure compatibility with your AC unit.
Use these instructions every one to three months to get all the benefits of a new air filter:
- Prepare: To start, shut off the AC system to prevent electrical damage. 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: Carefully remove the filter from the housing. Examine for holes or tears. If the filter is damaged, go ahead and replace it.
- Vacuum the filter: Use the brush accessory on your vacuum cleaner to clear out any dirt, hair, fibers and other small debris.
- Wash the filter: Take the filter outdoors and spray it down with a garden hose. For a filter that’s as clean as possible, apply a mild detergent.
- Dry the filter: Leave the filter out to dry completely before putting it back. In the meantime, don’t run your air conditioner or you risk bringing more dust particles inside the unit.
Additional Helpful Information About AC Filters and Routine Service
Kinds of AC Filters
Your filter type affects indoor air quality, ventilation efficiency and whether you should clean or change it when it becomes old. Here’s a summary of some popular options:
Disposable filters are usually made using fiberglass with a paper frame. These filters are designed for short-term use and are best replaced every one to three months. They are usually low cost and easy to replace but not very environmentally friendly as they generate waste.
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 maintenance is handled properly. They are more eco-friendly and budget friendly in the long run. That being said, cleaning them takes extra time and effort than simply replacing a disposable filter.
Electrostatic filters employ static electricity to trap pollutants effectively while maintaining airflow. These can be either disposable or reusable. Reusable electrostatic filters will need regular washing to maintain their effectiveness.
HEPA filters, or high-efficiency particulate air filters, are the top filters around, removing 99.97% of airborne particles as small as 0.3 microns. Most HEPA filters are single use, but they remain effective for up to an entire year before requiring replacement. While they deliver superior filtration, they are costlier and may not be compatible with all HVAC systems.
Additional Components of an AC Unit to Clean
Besides the filter, additional AC components require regular maintenance for best performance and longevity. Reach out to an HVAC professional for help servicing components including:
- The fan blades in your AC system will also accumulate dust and dirt. An HVAC technician will check the fan as part of their yearly tune-up, wiping down and adjusting the blades as needed to return to normal operation.
- The condenser coils located in the outdoor unit expel heat absorbed from your house. These coils are exposed to 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 thorough seasonal servicing to a professional.
- The evaporator coils inside the air handler extract heat from the air. After enough time, these coils collect a lot of dust, which restricts heat transfer efficiency. HVAC Experts employ a commercial-grade coil cleaner to remove dust and grime.
- The condensate drain lines in your AC unit can become clogged up with algae, mold and debris. If this happens, choose a professional contractor to clear the drain line using a commercial cleaner or mold treatment.
