- Check the pilot flame on older gas furnaces. An orange or yellow standing pilot flame (instead of blue) could be a sign of a problem. Inspect exposed ductwork for loose fittings or holes. Air leaks often leave dirt streaks on ducts.
- Keep your grills and registers free of dirt and debris. Dirty vents impede airflow.
- Look for signs of rust or signs of corrosion on your system.
- Inspect the blower and belt, if there is one. A cracked belt needs to be replaced.
- Replace or clean the air filter. Doing this on a monthly basis may cut your energy bill by 5 percent and protect your system from damage, according to the California Energy Commission.
- Allow sufficient air flow around your heating unit by keeping stored items well back from the furnace.
- Test the system controls.
- Lubricate moving parts to reduce friction in the motors and reduce energy use.
- Inspect the system for carbon monoxide leaks.
- Inspect the heat exchanger.
- Look at the flue for separated joints or holes.
