The Importance of Regularly Changing Your AC Air Filter: An Expert's Perspective

As an HVAC expert, I have seen firsthand the impact that a clean air filter can have on a home's air quality and energy efficiency. Many homeowners may not realize the importance of regularly changing their AC air filter, but it can make a significant difference in both the health of your home and your wallet. When an air filter becomes clogged and dirty, it forces the HVAC system to work harder to circulate air. This leads to higher energy consumption and ultimately, higher energy bills. But it's not just about saving money - a dirty air filter can also have negative effects on your health.

The filter collects dust, spores, hair, dander, and other particles that are then pumped through the air conditioning system. Breathing in these contaminants can cause respiratory issues and allergies. That's why it's crucial to change your home's air filter regularly. Most manufacturers and HVAC companies recommend changing the filter every 90 days or every 3 months. However, this timeline may vary depending on factors such as the location of your home (e.g.

dry and dusty climates), the presence of pets, and the age of your system and equipment. If you have pets at home, it's recommended to change the filter every 60 days or every 2 months. For homes with multiple pets or individuals with allergies or respiratory conditions, it's best to change the filter every 20 to 45 days. And for vacation homes or homes that are not used frequently, the filter should be changed every 9 to 12 months. The general rule of thumb is that the more you use your home, the more often you should change your air filter. By doing so, you'll not only improve your home's air quality but also prolong the life of your HVAC system.

The Benefits of Changing Your Cabin Air Filter

But it's not just your home's air filter that needs regular attention - your car's Cabin Air Filter is just as important.

A well-maintained vehicle will not only perform better but also provide you with many more years of service. By changing your cabin air filter every month or two, you can ensure that your car remains a reliable addition to your lifestyle. The cabin air filter is specifically designed to filter the air supply inside the vehicle, creating a cleaner environment while driving. It not only filters out pollen and dust particles but also acts as a barrier to prevent contaminants from entering the air conditioning system. Without a properly functioning filter, dust and other pollutants can enter the HVAC system and reduce its efficiency. It's worth noting that only high-efficiency particle (HEPA) air filters can trap allergens and spores.

Using an air filter with a MERV rating higher than what is recommended by the manufacturer can actually hinder the performance of your HVAC system. If you notice a bad smell coming from your ventilation grilles while using the heating or air conditioning, it's a sign that it's time to replace the cabin air filter. At All Temperature Air, we recommend changing your air filter regularly to ensure that your home and HVAC system work without any problems. While a cabin air filter may not need to be replaced as often as an oil filter, it's still important to follow a schedule and change it frequently. Pleated filters are often more effective than non-pleated ones, as they have a larger surface area to collect dust, pet hair, and other debris from the air.

Choosing the Right Air Filter

When it comes time to buy new air filters for your HVAC system, there are a few things to keep in mind.

First, make sure to choose the right size for your system. Most filters have a MERV (minimum efficiency reporting value) that indicates the type and size of contaminants they can filter out. It's important to choose a filter with a MERV rating that is suitable for your system. Additionally, it's important to change your air filter regularly, even if you have a high-efficiency one. If you neglect to change it often enough, moisture buildup can lead to mold growth in your ducts, which can cause serious health issues. In conclusion, changing your AC air filter regularly is crucial for maintaining good air quality in your home and prolonging the life of your HVAC system.

By following the recommended timeline and choosing the right filter, you can ensure that your home and car remain healthy and efficient for years to come.
