Common HVAC Misconceptions

One of the most persistent myths in home heating maintenance is the belief that you must replace your furnace filter every single month, no exceptions. While Harley’s Heating & Air encounters this misconception frequently during service calls in Lincoln, NE, the reality is much more nuanced than that.

The Real Story Behind Filter Replacement

The truth is that filter replacement frequency depends on several factors:

• Household size and occupancy
• Number of pets in the home
• Local air quality
• Filter quality and thickness
• Season and HVAC usage

For example, a single person living in a clean environment with no pets might only need to change their high-quality filter every 3-4 months. However, a family of five with three dogs and a dusty environment might indeed need monthly replacements.

The Cost of Over-Replacement

Unnecessarily frequent filter changes not only waste money but can also create additional environmental waste. The key is to inspect your filter regularly and learn to recognize when it truly needs replacement, rather than following an arbitrary schedule.

Professional Recommendation

Instead of blindly following the monthly replacement rule, we recommend checking your filter every 30 days and replacing it when it appears dirty or clogged. This practical approach ensures optimal furnace performance while avoiding unnecessary maintenance costs.

Remember, proper filter maintenance is just one aspect of keeping your heating system running efficiently. Regular professional maintenance from qualified technicians remains the best way to ensure your system’s longevity and performance.
