How do I know if my air filter needs to be replaced?

If you’re unsure when to replace your home’s air filter, watch out for these telltale signs indicating it’s time for a replacement. These indicators shed light on the crucial role air filters play in enhancing your home’s comfort and how a small investment of time and money can yield significant improvements:

1. Visible Dust Around Vents: It’s time to replace your filters when you can see visible dust accumulating on and around vents.
2. Dirty or Clogged Filter: A visibly dirty or clogged filter should be replaced promptly.
3. Extended Heating/Cooling Cycles: Longer HVAC cycles signal reduced airflow due to a clogged filter.
4. Higher Energy Bills: Increased energy consumption may result from a clogged filter.
5. Declining Indoor Air Quality: Worsening air quality suggests an overdue filter replacement.
