Typical furnace filters and ducing should be cleaned on an annual basis. Heating systems with HEPA filtration, electrostatic air cleaners or ultraviolet lights generally have cleaner ducts and less dust accumulated in the house, but the cold air return duct can be just as dirty as any standard system.
Clean just before the cold sets in.
What to look for in a standard cleaning:
- Furnace filter is located on the cold air return side of the furnace, eliminating the dust from entering the heating chamber. Replacement should occur twice a year to maintain a healthy furnace.
- Duct cleaning should occur annually to prevent dust and condensation from accumulating during the non-heating months.
- Duct cleaning could uncover some varmint activity. A good cleaning crew can tell when a supply line has been compromised and rodents have been in the heating system.
- Furnace tune-up is like maintaining the engine in your car. Efficiency is lost without proper maintenance.
