Replacing your furnace filter is one of the simplest ways to maintain efficiency and extend the life of your system. Most homeowners should replace their filters every 1–3 months, but the exact frequency depends on factors like furnace usage, presence of pets, dust levels, and allergies. High-efficiency filters may need closer attention, as clogged filters can restrict airflow, forcing your furnace to work harder, reducing efficiency, and potentially causing long-term damage.
Econoair recommends checking filters monthly during peak winter months. Our licensed technicians can help homeowners select the right filter type for their system, inspect it during maintenance visits, and ensure it’s installed correctly. With clean filters, furnaces operate efficiently, energy bills are reduced, and the system experiences less strain, ultimately prolonging its lifespan.
