Ocean City ductwork works seven months of the year
Your ducts move heated air from October through April here, with winter nights averaging 30°F from December through February. That is seven straight months of the system cycling on and off, pulling dust and debris through the same runs of duct over and over. Whatever settles in there gets pushed right back into the house every time the furnace kicks on.
Worcester County has seen 45 damaging wind events and 12 winter storms over the past ten years, and storms like that mean power interruptions. When the system shuts down and restarts, or when a home sits closed up during a storm, more dust has a chance to settle in the ducts before the air moves again. Over a long heating season, that buildup adds up, and it is the air moving through a dirty duct that ends up in the rooms you live in.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home. Homes with pets, a smoker, or someone with allergies tend to need it more often, since more dust and dander end up in the return air. If you see dust blowing out of the vents or it builds up fast on furniture after a cleaning, that is a sign to move the schedule up. A contractor can look at your ductwork and tell you what it actually needs.
- Is air duct cleaning worth it?
- It is worth it when there is a real reason for it, like dust everywhere, a musty smell from the vents, or work done on the ductwork recently that left debris behind. It will not fix an allergy problem on its own and it will not lower a heating bill. The value is in removing what has built up, not in some ongoing improvement to how the system runs.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or air tools to knock loose dust and debris from inside the supply and return runs, then pulls it out through the vacuum. The registers and grilles get cleaned too, along with the return vents. On a full job the coil and blower housing get looked at, since dust there affects airflow the same way dust in the ducts does.
