How Often Should You Change Your Air Filter in the Winter? A Guide for Homeowners

Maintaining a well-maintained central air system in your home is essential for ensuring clean air circulates throughout the house. Professionals, such as our team at Airco Service, Inc., recommend changing your air filter at least every three months, and even more frequently during the winter when you're more dependent on your heating system. It's important to visually inspect the filter every month to check for excessive particulate build-up. Factors such as the size of your home and air quality can affect the frequency of air filter replacement.

Smaller homes need a heating filter or air conditioning system to pump less air with the same amount of temperature change as larger homes, which will naturally need to pump more air. The primary purpose of an oven filter is not to clean the air you breathe, but to clean the air that passes through the oven and other HVAC equipment. People with allergies or respiratory conditions, such as asthma and COPD, may be affected by a dirty air filter, as their lungs are more sensitive to dust and dirt. Compared to other home improvement projects, changing air filters is a quick and painless process that can be done in less than an hour. If your HVAC has a single filtration system that uses an air filter for the air conditioning unit and boiler, replacements will be less frequent in winter than in summer.

The lifespan and replacement cycle of the boiler filter and air conditioner are affected by indoor and outdoor air quality. The filter is placed in a shared air controller where it cleans the air before diverting it to the conditioning unit or oven. Ideally, you should change your air filter every three months; however, there are certain factors to consider when determining when to replace an older filter. For instance, if you live in an area with high levels of dust or pollen, you may need to replace your filter more often than usual. Additionally, if you have pets or smoke indoors, you should also consider replacing your filter more frequently. In general, it's best practice to visually inspect your air filter every month and replace it when necessary.

This will help ensure that your HVAC system is running efficiently and that your family is breathing clean air. If you're unsure about how often you should replace your filter or need help with any other HVAC maintenance tasks, contact our team at Airco Service, Inc. for assistance.
