An annual inspection on your furnace can help identify potential problems before they become costly breakdowns and ensure your equipment is operating safely and efficiently. There are checks you can do yourself and those that need to be performed by a professional.
- Examine the heating system occasionally for signs of deterioration, such as water stains, corrosion or leakage.
- In forced-air systems, clean the furnace air filters frequently – at least twice a heating season.
- Keep the area around the furnace free from dust, lint, rags, paint, drain cleaners and other materials or chemicals that could catch fire or explode if they become too hot.
- Make sure warm-air outlets and cold-air outlets are not covered by carpets or blocked by debris.
- Make sure walls, other obstructions or new renovations do not block the heating system’s air supply.
