One of the Most Frequent HVAC Issues We See Starts With a Simple Oversight: Filter Replacement.
Every HVAC system relies on a clean filter to function at its best. The filter’s main job? Trap airborne pollutants, such as dust, pollen, pet dander, and cleaning products. When a filter is past its prime, these particles circulate right back into your living spaces, lowering indoor air quality.
But there’s a bigger risk: a clogged filter blocks airflow. The system must work harder to move air, which means higher utility bills and unnecessary strain on expensive equipment. In extreme cases, restricted airflow can lead to overheating or freezing up, leaving you without heat or cooling when you need it most.
If it’s been years since your last HVAC filter replacement—or if you’ve never replaced the filter—no worries. We won’t judge you. But here’s why we recommend our clients in Issaquah, WA, and surrounding areas make replacement a regular habit.
