Seven months of heat means seven months of dust moving through your ducts
Most of Kings County lives in attached and multi-unit buildings, so ductwork often runs through shared walls and tight chases before it reaches a vent. From October through April, that system runs almost nonstop trying to keep up with nights near 29°F, and every cycle pushes more dust, dander, and fine debris through the same runs of ductwork.
Over years that buildup lines the inside of the ducts and settles on the coil, so the system has to work harder to move the same amount of air. In a building where you do not own the unit outright, a duct system nobody has looked at in years is easy to forget about until the air coming out of the vents feels thin or smells stale.

- How often should air ducts be cleaned?
- There is no fixed interval that fits every home, so a contractor should tell you based on what they find inside your ducts. Signs that it is time include dust settling again soon after cleaning, a vent blowing out visible debris, or someone in the house dealing with allergies that seem worse indoors. If you just moved in and don't know when the ducts were last cleaned, it's worth having them checked so you have a starting point.
- Is air duct cleaning worth it?
- It depends on what is actually going on in your home. If dust keeps piling up fast, a vent is pushing out debris you can see, or someone's breathing troubles seem tied to the air indoors, then yes, it is worth having a contractor look. If the ducts are doing their job and nobody has symptoms, cleaning them just to have it done will not change much. Check the furnace filter too, since a dirty filter causes a lot of the same complaints people blame on the ducts.
- What does air duct cleaning involve?
- A contractor hooks a vacuum system up to the ductwork, then uses brushes or air tools to knock dust and debris loose from inside the duct walls so it pulls out through the vacuum. Each supply and return vent gets opened and cleaned on its own rather than all at once. The vents, the grilles and sometimes the blower compartment get wiped down as part of the same visit. A contractor can walk through what your duct layout needs before starting.
