How Air Filters Actually Impact Your Energy Bills


The Common Misconception About HVAC Filters

Many homeowners believe that using the highest-rated air filter available will automatically result in better HVAC performance and improved energy efficiency. However, this widely-spread myth needs some careful examination.

Here’s what you really need to know about air filters and energy consumption:

The Truth About Filter Ratings

1. Higher MERV ratings don’t automatically mean better performance
2. Too restrictive of a filter can actually increase energy consumption
3. The right filter depends on your specific HVAC system’s specifications and your home’s needs

Finding the Right Balance

Your HVAC system is designed to handle a specific level of airflow resistance. When you install a filter that’s too restrictive, your system has to work harder to pull air through, which can:

– Increase energy consumption
– Put extra strain on your blower motor
– Reduce overall system efficiency
– Potentially lead to system failures

The Smart Approach

Instead of automatically choosing the highest-rated filter, consider:

1. Consulting your HVAC manual for recommendations
2. Regular filter replacement schedule
3. Balancing air quality needs with system efficiency

Remember, the goal is to find the sweet spot between air quality and system performance. A mid-range MERV filter (8-11) often provides excellent filtration without compromising system efficiency for most residential systems.

At Bruton Comfort Control, we recommend regular maintenance and proper filter selection to maintain optimal system performance. By choosing the right filter and maintaining a regular replacement schedule, you can ensure both clean air and energy efficiency in your home.

The Bottom Line

Don’t fall for the myth that the highest-rated filter is always the best choice. The key to optimal HVAC performance lies in choosing the right filter for your specific system and maintaining it properly.
