Common HVAC Filter Myths That Could Be Costing You Money


The Truth About HVAC Air Filters That Might Surprise You

One of the most persistent myths in home heating and cooling is that expensive, high-MERV air filters are always the best choice for your HVAC system. At Childs Heating & Air, we regularly encounter homeowners across Donelson, Hermitage, and surrounding Tennessee communities who believe this common misconception.

Let’s debunk this costly myth once and for all.

The truth is:

  • Higher MERV ratings don’t automatically mean better system performance
  • Ultra-dense filters can actually restrict airflow
  • Restricted airflow forces your system to work harder
  • This extra strain can lead to increased energy bills and potential system damage

What many homeowners don’t realize is that most residential HVAC systems are designed to work optimally with medium-efficiency filters (MERV 8-11). Using filters with higher ratings without proper system modifications can do more harm than good.

The key is finding the right balance between:

  • Air filtration efficiency
  • System performance
  • Energy consumption

Whether you’re in Mt. Juliet, Lebanon, or Old Hickory, the best approach is to consult with HVAC professionals who can recommend the most appropriate filter for your specific system and needs. Regular maintenance and proper filter selection will ensure your system runs efficiently while maintaining healthy indoor air quality.

Remember: The most expensive option isn’t always the best solution for your home’s heating and cooling needs. Focus instead on regular maintenance and appropriate filter choices for optimal performance and longevity.
