Frequently Asked Questions
How often should I change furnace filters before the heating season?
For most homes, replace pleated filters every 90 days for MERV 8–11 levels. If you have pets, high dust, or use MERV 13 media, check filters every 30–60 days—replace sooner if visibly dirty or airflow is reduced.
Will a higher MERV filter damage my furnace?
A properly sized higher-MERV filter won’t ‘damage’ your furnace, but very dense filters (and some MERV 13+ options) can reduce airflow on older or low-capacity blowers. Confirm your HVAC manufacturer's recommendations and monitor system airflow and temperature after installing higher-MERV media.
What else should I include in a fall furnace filter & vent replacement kit?
Include the correctly sized spare filters, a screwdriver set, flashlight, foam gasket or weatherstripping tape for sealing the grille, a small pack of sheet-metal screws or mounting clips, a vacuum or brush to clean the return, and HVAC foil tape or silicone for small leaks. Consider a magnetic or snap-fit return grille replacement if the existing grille is bent or damaged.
