The Truth About Furnace Filter Changes

As experts in heating systems, we at Heat Engineering frequently encounter misconceptions about home maintenance practices. Today, we’re tackling one of the most persistent myths about furnace care that could be impacting your wallet and comfort.

The Myth: Expensive Filters Are Always Better

Many homeowners believe that purchasing the most expensive furnace filter with the highest MERV rating will automatically result in better air quality and furnace performance. This isn’t necessarily true.

Here’s why this myth needs debunking:

• Higher MERV ratings can restrict airflow if your system isn’t designed for them
• Some budget-friendly filters work perfectly well for basic filtration needs
• Over-filtration can strain your furnace’s blower motor

The Reality

The truth is that the best filter for your furnace depends on several factors:

• Your furnace’s specifications
• Your home’s specific air quality needs
• The type of debris typically present in your environment

At Heat Engineering, we recommend consulting with a professional to determine the ideal filter rating for your specific system. What works for one home might not work for another, and using the wrong filter can lead to increased energy costs or even system damage.

Remember to change your filters regularly – typically every 1-3 months, depending on usage and environmental factors. This simple maintenance task can help ensure your heating system operates efficiently and extends its lifespan.
