Common HVAC Filter Myths That Could Be Costing You Money


The Truth About HVAC Filters and Your Home’s Efficiency

At Four Suns Heating & Cooling, we often hear misconceptions about HVAC maintenance that can lead to unnecessary expenses and reduced system efficiency. One of the most persistent myths we encounter during our service calls in Naperville involves air filters.

The Popular Myth

Many homeowners believe that the more expensive and dense the filter, the better it is for their HVAC system. This isn’t always true, and here’s why:

  • Higher-density filters can restrict airflow
  • Excessive filtration may strain your system
  • Some premium filters are overkill for basic needs

The Reality

Your HVAC system is designed to work with a specific level of airflow. Using an unnecessarily dense filter can actually reduce your system’s efficiency and potentially lead to:

  • Increased energy consumption
  • Higher utility bills
  • Reduced system lifespan
  • Unnecessary strain on components

Instead of automatically choosing the most expensive filter, consult with a professional to determine the right balance between filtration and system efficiency. The ideal filter will protect your system while maintaining proper airflow.

The Solution

For most residential systems, a medium-grade MERV 8-11 filter provides excellent filtration without compromising system performance. Regular maintenance and proper filter selection can help ensure your system runs efficiently year-round.
