Changing your air filter is one of the easiest and most cost-effective ways to maintain and enhance your HVAC system’s efficiency, longevity, and air quality. In this blog, we’ll walk you through the hows and whys of changing your HVAC air filter, and the risks of not changing them on time.

Air filter change frequency

When it comes to changing your HVAC air filter, frequency is key. The frequency of change depends on the type of filter you use and how often the HVAC system runs. Generally speaking, you should be replacing standard 1-inch fiberglass filters every 30 days or so, while pleated filters can last up to 3 months before they need to be replaced

If your filter is clogged with dirt, dust or pet dander, you should replace it more frequently to ensure the optimal performance of your system. Also, if you have a member of your household who suffers from allergies or asthma, you may want to change the filters more often.


How Often Vancouver Homeowners Should Change Their HVAC Air Filters

If you live in Vancouver, BC, the specific climatic and environmental conditions of this region may affect how often you should change your HVAC air filters. Vancouver’s climate is classified as a moderate oceanic climate, which means it experiences mild winters, cool summers, and a high level of humidity throughout the year. This environment can create an ideal breeding ground for mold and mildew, which can easily become airborne and clog up your HVAC filters.

Furthermore, Vancouver is known for its high pollen counts, particularly during the spring and early summer. If you or anyone living in your house suffers from allergies, it’s critical to change your filters more frequently during these months to ensure optimal indoor air quality. Given these conditions, homeowners in Vancouver should consider changing their HVAC air filters at least every 1-2 months. Always consult with an HVAC professional to determine the best schedule for your specific situation and system.


The Risks of Neglecting Your HVAC Air Filter Change

Neglecting to change your HVAC air filter can lead to a series of unpleasant complications that extend beyond just discomfort. When your filter is clogged, the efficiency of your HVAC system plummets, forcing it to work harder to maintain the desired temperature. This not only leads to increased energy consumption and higher utility bills but also causes undue wear and tear on your HVAC system, potentially leading to costly repairs or premature system failure.

Moreover, a dirty filter can no longer adequately filter out pollutants, allergens, and microorganisms from the air. This decline in air quality can exacerbate allergy symptoms, trigger asthma attacks, and even pose health risks to individuals with respiratory conditions. In extreme cases, a severely clogged filter can also pose a fire risk.

Changing your HVAC air filter is an essential part of maintaining the efficiency and safety of your HVAC system. Regularly scheduled filter changes can help you save money on energy bills and avoid costly repairs, as well as provide you with improved indoor air quality. So, don’t forget to change your air filters according to the schedule prescribed by your HVAC professional.


Tips for Easier HVAC Air Filter Maintenance

To make your HVAC air filter maintenance routine easier, consider taking the following steps:

  • Make a schedule: Set up reminders on your phone or calendar to change your filters according to the frequency prescribed by your HVAC professional.

Troubleshooting Common Air Filter Problems

If you’re having trouble with your air filter, such as a strange odor or loud noise coming from the system, you may need to troubleshoot. The most common issues are caused by clogged filters or a malfunctioning fan motor.

  • Check your filter: Make sure that your filter is clean and free of debris. Replace it if necessary.

  • Inspect the vents: Check for any visible dust buildup or blockages in the air vents and clean them accordingly.

  • Check the fan motor: If your fan is making buzzing noises, it could indicate a malfunctioning motor which will require professional attention.
