Common Air Filter Myths That Are Costing You Money

The Truth About HVAC Air Filters: Separating Fact from Fiction

As heating and cooling professionals serving communities across Illinois and Indiana, we frequently encounter misconceptions about HVAC air filters. Today, we’re setting the record straight on some costly myths that might be affecting your home’s comfort and efficiency.

Myth #1: More Expensive Filters Are Always Better

While premium filters can offer superior filtration, they’re not always the best choice for every system. Some high-end filters are so dense they can actually restrict airflow and make your system work harder, potentially leading to increased energy costs and premature wear.

Myth #2: You Only Need to Change Filters Once a Year

This is perhaps the most dangerous myth we encounter. Most filters need replacement every 60-90 days, and some homes require monthly changes, especially if you have:
• Pets
• Family members with allergies
• High dust levels
• Construction nearby

Myth #3: The Filter’s Only Job Is to Clean Your Air

While air filtration is important, your HVAC filter’s primary purpose is protecting your system’s components from debris. Clean filters help maintain efficiency and prevent expensive repairs by keeping dust and dirt away from sensitive mechanical parts.

The Bottom Line

Regular filter maintenance is crucial for your HVAC system’s longevity and efficiency. Don’t fall for myths that could compromise your comfort and increase your energy bills. When in doubt, consult with a professional who can recommend the right filter type and replacement schedule for your specific system.

Remember: proper filter maintenance is just one aspect of keeping your HVAC system running optimally. Regular professional maintenance ensures your system operates efficiently year-round, saving you money and preventing unexpected breakdowns.
