Salinas ducts run seven months of the year
Your furnace pulls air through the ducts from November through May, seven months a year. On winter nights averaging 38°F, it cycles on and off for hours at a stretch, and every cycle pulls household dust and whatever is loose in the ducts back through the system.
Most homes in Monterey County are single-family houses, and most of those are owner-occupied, so what has settled in the ducts has built up over years in the same house, not left behind by a string of renters.
- 7 months

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every house. Homes with pets, a smoker, or someone with allergies tend to need it more often, since dander and dust build up faster than in other homes. If you see dust blowing out of the vents when the system starts, or notice more dust settling around the house than before, have them checked.
- Is air duct cleaning worth it?
- It is worth it if your ducts are visibly dirty, if rodents or insects have gotten into them, or if someone in the house has allergies that act up more indoors than outside. Cleaning removes dust, pet hair, and debris that the airflow would otherwise push back into the rooms. It will not fix a system that is undersized or poorly laid out, so a contractor should look at the ducts before you pay for cleaning.
- What does air duct cleaning involve?
- A contractor opens access points in the ductwork and uses a vacuum system with brushes or air whips to loosen and pull the dust and debris out. Both the supply and return ducts get cleaned, along with the grilles and registers. Most contractors also clean the blower compartment, since dust collects there too and gets pushed right back into the ducts if it is left alone.
