Answers to Common Winter HVAC Questions
How frequently should furnace filters be replaced in winter? For most households, swapping filters every 30 to 60 days during heavy use is ideal. Homes with pets or allergy sufferers may need more frequent changes to maintain air quality.
What is the typical lifespan of a furnace? With consistent care, including annual tune-ups and filter maintenance, a furnace can last 15 to 20 years, often reaching the upper limit when well-maintained.
How do I know if my furnace poses a safety risk? Look for indicators like soot buildup near the unit, a yellow flame instead of blue, frequent on-off cycling, or a triggered carbon monoxide alarm. If any of these occur, turn off the system immediately and contact a technician.
Is annual duct cleaning required? Not usually, though an inspection every few years is advisable. Cleaning becomes necessary if you observe mold, excessive dust, or evidence of pests within the ductwork.
By adhering to this expert-driven checklist, you position your home for a winter of reliable comfort and efficiency. Preparation is the foundation of success, and with these actionable steps, your HVAC system will stand ready to weather every cold snap with ease.
