Is It Time To Replace Your HVAC Filter?

Regularly changing your HVAC (heating, ventilation, and air conditioning) filter is important for several reasons:

• Improved Air Quality: The primary function of the filter is to trap dust, pollen, pet dander, and other airborne particles. Over time, the filter becomes clogged with these contaminants, reducing effectiveness. Regularly changing the filter ensures that the system continues to filter out these particles.
• Energy Efficiency: A dirty filter restricts airflow through the system, making it work harder to heat or cool your home, resulting in higher energy consumption (and a higher bill). Regularly changing the filter helps maintain optimal airflow and improves the system’s efficiency.
• Extended Equipment Life: When the system has to work harder due to a dirty filter, it experiences increased wear and tear, leading to mechanical issues and a shortened lifespan over time. Regular filter changes can contribute to the longevity of your system, saving you money on repairs and replacements.

Always use manufacturer recommendations for replacing filters. Many factors can affect how quickly a filter gets dirty—if you have pets, your climate, etc.—but generally, most manufacturers recommend changing air filters every 60 to 90 days.
