AC Maintenance: How Often Should You Change Your Air Filter?
Air filters are an essential component of any HVAC system, helping to keep the air in your home clean and free from harmful particles. However, like many other household items, they need to be replaced periodically to maintain their effectiveness. But how often should you change your air filter? The answer is not as straightforward as it may seem. This guide offers essential tips on how often to replace your home air filter, considering factors like filter type, pets, allergies, and local pollution.
Why is it necessary to change the air filter?
An uncleaned air filter makes the working of your HVAC system harder, leading to more breakdowns. The replacement of the air filter is one of the quick and painless processes. However, many homeowners are unaware of how often they should change their air filters, leaving them vulnerable to damage. Your air filter is responsible for trapping various dust particles, pet hair, and other irritating particles, enabling your air conditioning to deliver fresh, clean air throughout the house. Consequently, if this accumulated dust and debris aren’t removed from the air filter, it will travel to the HVAC unit, leading to:
High Energy Bills: When dust or debris clogs the HVAC unit, the system has to work harder to draw air through to cool or heat the room. Eventually, it causes the HVAC unit to run for a prolonged time, leading to high electricity bills.
Health Concerns: Improper working of air filters can cause the dust and dirt to circulate in the house, leading to allergies and respiratory illness.
System Failure: When the HVAC system has to work harder to draw air through a clogged filter, it puts consistent strain on the unit, causing it to break. Ultimately, you have to pay hefty amounts for expensive air conditioning repair in Sacramento.
Factors Affecting How Often You Replace Your Air Filter?
ypically, air filters should be replaced every three months. However, several factors need to be considered when determining the appropriate time for replacement.
Type of Air Filter: The quality of air filter plays a significant role in longevity and effectiveness. Lower quality fiberglass filters are affordable, but they have poor durability and need replacement every month. High-quality filters such as pleated air filters are most effective in trapping particles and last for over two months.
Pets: If you are a pet owner, you might need to change your air filter every two months to ensure optimal air quality in your home. Pets can shed fur and dander, which can quickly accumulate and reduce the efficiency of your air filter, so keeping a regular maintenance schedule is important to maintain a clean and healthy living environment.
Allergies: If any of your family members are allergic to dust or dirt, it's important to take preventative measures to ensure their comfort and health. Consider changing your air filter every 50 days, as even the minutest dust particles circulating in the air can trigger allergic reactions.
Children: Children are particularly sensitive to dust and dirt, so maintaining high indoor air quality is crucial. To achieve this, replacing the air filter every two months is essential.
Home Use: If you use your HVAC system daily, your air filter might require more frequent replacement compared to a vacation home that doesn’t filter air regularly. In homes where the HVAC system is in continuous use, it's important to check and replace the air filters more often to ensure optimal air quality and system efficiency. On the other hand, if your home’s HVAC system operates only a few times a year, replacing the air filters every six to 12 months should suffice. Regular maintenance not only extends the life of the system but also contributes significantly to a healthier living environment by keeping pollutants and allergens at bay.
How To Know What Filter to Buy
To ensure you select the right filter for your HVAC unit, follow these steps:
- Consult with the installer who set up your system for guidance.
- Look for a label on the unit indicating the recommended filter size, typically found inside the unit's panel or near the filter slot.
- For added accuracy, take a picture of your current filter before shopping, making it easier to find an exact match and maintain your HVAC system's efficiency.
- Common filter sizes include 16x20, 16x25, and 20x25 inches. However, it's vital to verify the precise dimensions for your specific model to ensure optimal performance.
How to Replace Your HVAC Air Filter
Replacing your air filter is a simple and easy process that can be done in just a few minutes. Here's how:
- Locate your HVAC unit, commonly found in the basement, attic, or a utility closet, especially if you have central air conditioning. It's important to identify the unit's location to ensure proper maintenance.
- Before proceeding, turn off your unit to ensure safety while you are swapping out the air filter. This precaution helps prevent any accidental injury or damage to the system.
- Carefully remove the old filter, taking note of its size and orientation, as this will guide you when installing the new one. Filters often have an arrow indicating airflow direction, which is essential to follow for optimal performance.
- Use a rag or vacuum cleaner to thoroughly clean up any residual dust and debris from the filter compartment. This step is crucial for maintaining optimal airflow and preventing dirt from circulating through your HVAC system.
- Insert the new air filter, making sure it matches the size and orientation of the old one for a proper fit and maximum efficiency. A correct fit ensures that your system operates efficiently and effectively filters out impurities.
- Check that there are no gaps around the filter once it's in place by ensuring a snug fit. Gaps can allow unfiltered air to bypass the filter, reducing the system's efficiency and potentially causing issues.
- Turn the unit back on and listen attentively for any unusual noises, as these could indicate that something hasn’t been installed correctly. It's important to address such issues promptly to avoid damage to the system.
- Record the date you replaced the filter in a maintenance log or on a calendar as a gentle reminder for the next replacement. Typically, filters should be replaced every 1-3 months, depending on usage and the type of filter, to maintain the system's performance and air quality.
