Breathe in, breathe out—what’s in the air around you? If you think furnace filters are just a forgettable piece of your HVAC system, it’s time to think again. These simple tools can enhance your well-being and save money, making them indispensable. Let’s debunk the myths.
“You only need to change filters annually”
Waiting too long between filter changes can wreak havoc on your HVAC system. Filters typically need replacement every 1–3 months, depending on factors like household size, usage, and whether you have pets.
“Thicker filters are always better”
A thicker filter isn’t always better; although they capture more particles, they may restrict airflow if your system can’t handle them. Too thick of a filter can strain your furnace’s blower motor and reduce system efficiency.
“All furnace filters are the same”
Furnace filters come in different materials, sizes, and MERV ratings (Minimum Efficiency Reporting Value). High MERV filters trap tiny particles, but they can limit airflow if your system isn’t equipped for them.
“Reusable filters are more economical”
It might seem economical to use reusable filters, but they require thorough cleaning to work effectively. Neglecting proper maintenance can reduce efficiency and mold growth, ultimately costing you more in the long run.
“Expensive filters are always the best choice”
The best filter for your home depends on your system’s specifications and unique needs. Consider factors like allergies, pets, and your system’s requirements to choose a filter that balances efficiency and cost-effectiveness.
“Replace filters only when dirty”
Even if a filter looks clean, it may still be clogged with microscopic particles. A dirty filter restricts airflow, which puts strain on your system and reduces its efficiency. Regular replacement is essential to keep your HVAC running smoothly.
“Air purifiers replace furnace filters”
Furnace filters protect your furnace from dust and debris, helping maintain airflow and prevent wear. Even with air purifiers, they still serve a key role. The air purifier handles finer particles, while the filter protects the more significant system components.
“Furnace noises are normal”
Unusual sounds from your furnace often signal underlying issues. Squealing may point to a worn belt, while rumbling could indicate dirty burners or airflow problems. Neglecting these sounds may result in more serious issues and costly repairs.
“Insulation doesn’t make a big difference”
Proper insulation plays a huge role in reducing energy costs. Even minor improvements like sealing gaps or adding insulation to attics and walls can significantly decrease energy loss and minimize the strain on your furnace, lowering energy usage.
“Energy-efficient models aren’t worth it”
Furnace efficiency impacts your energy bills year-round, especially in regions with fluctuating temperatures. A more efficient furnace can better regulate indoor temperatures, improving comfort and reducing costs during winter and transitional seasons.
