If you don't replace the air filter in your air conditioning system, it can quickly become clogged with dust and debris, preventing proper air filtration. This can lead to a variety of problems, such as system inefficiency, increased energy bills, inadequate air quality, and faults. To avoid these issues, it's essential to change the air filter regularly and have the system inspected. Switching out the filter on a regular basis can help preserve the life of the system and make it work more efficiently.
The most effective filters are reusable, usually with metal frames, and can be cleaned according to the manufacturer's instructions. If you're uncertain what type of filter is best for your system or how often you should change it, contact an HVAC technician for advice. Reusable filters should be cleaned according to the manufacturer's instructions. If you don't change or clean the filter, you'll notice that the air stagnates and it's harder to reach the desired temperatures.
This can also lead to a costly repair bill if you have to shut down your system for repairs or replacement. A clogged filter allows dust and other contaminants to reach ducts, fans, and other parts, soon causing them to accumulate. Once you understand what really happens when you forget to change the filter, you'll likely feel more motivated to replace it on a consistent basis. When the filter becomes clogged and air can't pass through it, the air conditioning system will work harder to push the air out.
This can also affect indoor air quality if pollen and dander are more likely to enter your home or business. Of course, this can vary depending on factors such as the type of air conditioning system you have and the filter you use. If you change your air conditioning filter every month during peak cooling season, you can save approximately 15% each month on utilities and avoid repair problems due to airflow restrictions. If you've never changed your air conditioner filter before, it's best to ask an HVAC technician to do it for you the first time.
If you've switched to a higher-efficiency filter as part of a COVID mitigation strategy or simply to alleviate allergy symptoms, remember that these filters need to be changed more frequently than standard HVAC filters. The owner's manual for your air conditioning system is the best source of information on how often you should change your air filters.
