The Truth About HVAC Filters: Debunking a Common Misconception – San Francisco Remodeling & Construction

At Guardian Heating & Cooling, we often encounter myths and misconceptions about HVAC systems. Today, we’re tackling a widespread belief that many homeowners in Chicago, Northbrook, Lincoln Park, Skokie, Glenview, and Highland Park hold: the idea that using the highest-rated HVAC filter will always result in the best air quality and system performance.

The Myth

Many people believe that installing the highest MERV (Minimum Efficiency Reporting Value) rated filter in their HVAC system will provide the cleanest air and the best overall performance. This misconception leads homeowners to purchase expensive, high-MERV filters without considering the potential consequences.

The Truth

While it’s true that higher MERV ratings indicate better filtration, using a filter with too high a rating for your specific system can actually cause problems. Here’s why:

Reduced airflow: High-MERV filters are denser, which can restrict airflow in systems not designed to handle them.
Increased energy consumption: Your HVAC system may work harder to push air through a dense filter, leading to higher energy bills.
Potential system damage: In extreme cases, using an incompatible filter can strain your system, potentially leading to premature wear or breakdowns.

The Solution

Instead of automatically opting for the highest-rated filter, consider these steps:

1. Consult with a professional: Our experts at Guardian Heating & Cooling can assess your system and recommend the optimal filter rating.

2. Balance filtration and airflow: Choose a filter that provides good air quality without compromising your system’s performance.

3. Regular maintenance: Schedule routine check-ups to ensure your HVAC system is running efficiently with the right filter.

Remember, when it comes to HVAC filters, the best choice is one that balances air quality with system efficiency.
