What humid air leaves behind in your ducts
Escambia County only needs heat five months a year, November through March, which means the air handler is pushing cooled air through the ducts the rest of the time. That cooled air meets warm, humid air at the duct walls, and moisture collects there. Dust and debris stick to that moisture instead of blowing through, and it builds up along the seams over time.
Power loss makes it worse. Florida households went dark for 24 hours or more in 38% of cases last year, and the county has logged 72 damaging wind events over the past ten years. When the power drops, the air handler stops moving air, but the humidity in the ducts does not go anywhere. Whatever is already built up inside sits there with no airflow to dry it out until the system comes back on.

- How often should air ducts be cleaned?
- There is no set schedule that fits every house, but most homes do not need it often. If anyone in the house has allergies, or you have had a rodent problem or water damage near the ducts, do it sooner rather than later. A contractor can look inside the ducts and tell you what is actually in there before you decide.
- Is air duct cleaning worth it?
- It depends on what is actually in the ducts. If you can see dust coming out of the vents, or there is a musty smell when the air runs, cleaning will help. If the ducts look fine and the air smells fine, cleaning them will not make your system heat or cool any better. A contractor can inspect the ducts with a camera and show you what is really in there before you pay for anything.
- What does air duct cleaning involve?
- A technician connects a vacuum system to the ductwork, then uses brushes or air whips to knock dust and debris loose so it gets pulled into the vacuum. Each vent gets cleaned this way, along with the main trunk lines. The filter and any coils inside the system are separate from the ducts, so they may need their own attention depending on their condition.
