Here’s a fun fact: a dirty air filter can make your HVAC system work up to 15% less efficiently. That’s according to the Department of Energy, which also notes that a dirty HVAC filter can cause increased energy bills and force your system to work harder.
That’s why it’s essential to replace your HVAC air filter regularly, especially in the summer when the weather is unbearable. This post will guide you through how often you should replace your HVAC air filter for optimal system function.
Let’s dive in and find out how to keep your HVAC air filter in top condition!
Factors that Determine How Often You Should Replace Your HVAC Air Filter
When was the last time you had your HVAC air filter replaced? The frequency at which you should replace your air filters depends on several factors. These include:
- Type of Air Filter: The type of air filter you use in your HVAC system can affect how often you need to replace it. Some filters are designed to last longer than others, and some are more efficient at capturing airborne particles. During summer, when air conditioning is more in use, it helps to use air filters that are more efficient at capturing airborne particles.
- Fiberglass Filters: These filters are the most basic and least expensive. They are designed to capture large particles such as dust, debris, and lint, but they don’t do much to filter out smaller particles. They need to be replaced every 30 days.
- Pleated Filters: These filters are more efficient at capturing airborne particles than fiberglass filters. They are made of folded material that traps more particles and must be replaced every 90 days.
- HEPA Filters: These filters are the most efficient at capturing airborne particles. They can capture up to 99.97% of particles as small as 0.3 microns. However, they are also the most expensive and must be replaced every 6-12 months.
- Level of Air Pollution: Outdoor air pollution levels may increase during the summer, making it necessary to replace your air filter more frequently. If you live in an area with high outdoor air pollution levels, have pets, or smoke indoors, consider replacing your air filter every month.
- Frequency of HVAC Use: The more you use your HVAC system, the more frequently you need to replace your air filter. If you use your HVAC system often, you may need to replace your air filter every month. However, if you only use your HVAC system occasionally, you may be able to get away with replacing your air filter every three months.
- System Age and Condition: The age and condition of your HVAC system can affect how often you need to replace your air filter. If your system is older and in poor condition, it may produce more dust and debris, clogging your air filter more quickly. In this case, you may need to replace your air filter more often.
Signs That Indicate the Need for Filter Replacement
Regularly replacing your HVAC air filter is essential. But how do you know when it’s time to replace it? Here are some signs that indicate the need for filter replacement for optimal cooling this summer:
- Poor Airflow: If you notice that your HVAC system is not providing adequate airflow, it may be a sign that your air filter is clogged with dust and debris. A dirty air filter restricts the amount of air that can flow through your HVAC system, causing it to work harder and less efficiently.
- Dust Buildup: If you notice excessive dust on your furniture or around your air vents, it may be a sign that your air filter needs to be replaced. A dirty air filter allows dust and debris to circulate throughout your home, which can lead to allergies and respiratory problems.
- Strange Smells: If you notice a musty or stale smell coming from your HVAC system, it may be a sign that your air filter needs to be replaced. A dirty air filter can trap moisture and mold, which can lead to unpleasant odors.
- Increased Energy Bills: If you notice a sudden increase in your energy bills, it may be a sign that your air filter needs to be replaced. A dirty air filter causes your HVAC system to work harder and less efficiently, which can raise your energy bills.
- Unusual Noises: Unusual noises from your HVAC system, such as rattling or whistling, maybe a sign that your air filter needs replacing. A dirty air filter can cause your HVAC system to work harder and make these noises.
Tips for Maintaining Your HVAC Filter for the Summer
Maintaining your HVAC air filter is essential for keeping your indoor air clean and your HVAC system running smoothly. Not sure where to start? Here are some tips for maintaining your HVAC air filter to ensure optimal cooling and comfort in your Terrell, TX, home.
- Choose The Right Type Of Air Filter: Ensure you choose the right air filter for your HVAC filters. Look for filters that are the correct size and have the appropriate MERV rating for your needs. Higher MERV ratings indicate better filtration but can also restrict airflow if the filter is too dense.
- Regularly Check And Replace Your Air Filter: It is essential to check your air filter regularly and replace it when necessary. Most air filters need to be replaced every one to three months, depending on the factors discussed above.
- Keep Your HVAC System Clean: Regularly cleaning your HVAC system can help extend the life of your air filter. An HVAC maintenance service can help clean the air vents, ductwork, and other HVAC system components to reduce the amount of debris that can clog your air filter.
- Change Your Air Filter During Home Renovations: You must change your air filter after completing renovations on your home. Construction dust and debris can quickly clog your air filter, reducing airflow and causing your HVAC system to work harder.
- Consider Upgrading To A High-Efficiency Air Filter: If you or someone in your home has allergies or respiratory problems, consider upgrading to a high-efficiency air filter. These filters can trap smaller particles and improve air quality, reducing allergy symptoms.
