- Unusual HVAC Noises: Strange sounds from your HVAC system can indicate that it’s struggling due to a clogged filter.
- Visible Dirt: Inspect the filter; if it looks gray or has visible dirt, it needs replacement.
How Often Should You Check Your Air Filter?
Regular maintenance is key to ensuring your air filter functions properly. Generally, you should check your air filter every 1 to 3 months, but this can vary based on several factors:
