HVAC filters: the one habit that pays for itself
No home maintenance task has a better return than changing your HVAC filter on time. It’s cheap, it’s quick, and skipping it is how comfortable systems quietly become broken ones.
What a dirty filter costs
A clogged filter chokes airflow, so the blower strains, energy use climbs, and the whole system runs hotter and harder than it should. Over time that stress is what turns a routine season into a repair bill.
How often, really
A basic filter wants changing every 1–3 months; homes with pets or allergies lean toward the shorter end. The trick isn’t knowing the interval — it’s remembering the exact size when you’re standing in the store.
Never guess the size again
Store the filter dimensions against your furnace in HearthIQ once, set the reminder, and the recurring question — "what size was it again?" — simply goes away.
