  1. Every single month
  2. Every year, no exceptions
  3. Not routinely, only as needed ✔

Why: EPA does not recommend cleaning ducts routinely, only as needed. Duct cleaning has never been shown to prevent health problems, and a light amount of household dust in ducts poses no known risk.

Huh, didn't know that: EPA does recommend inspecting and servicing fuel-burning furnaces, stoves and fireplaces before each heating season.
