How Often Should South Florida Homes Clean Their Ducts?
There's no set schedule for duct cleaning in South Florida. Five common household situations and what each one usually needs.
Ads sometimes say you should clean your ducts every year or two. The EPA disagrees. It doesn't recommend duct cleaning as routine maintenance, and it advises against hiring companies that do. That's true even in South Florida, where air conditioners run nearly all year. The right timing depends on what's happening in your home. Rather than a single number, here are five common situations and what each one tends to need.
Five common situations
Situation 1: A well-kept home with no recent changes
You change the filter regularly, the system gets serviced, nobody has done any remodeling, and the registers look clean.
What it usually needs: probably no duct cleaning right now. Keep up with filters and HVAC maintenance. The EPA notes that much of the dust in ducts sticks to the duct surfaces and doesn't necessarily enter the living space, so a little dust inside a duct isn't a problem by itself.
When to reconsider: if you start seeing dust blowing from vents, heavy buildup on returns or any of the situations below.
Situation 2: You just renovated
Kitchen remodels, flooring replacement, drywall work and window or door replacement all create fine dust. If the AC ran during the work, some of that dust likely went through the returns.
What it usually needs: a cleaning after the work is done is often worthwhile. Remove a register and look inside with a flashlight. If you see drywall dust or debris, air duct cleaning can help remove it. For your next project, the EPA suggests sealing off supply and return registers and not running the system until the dust is cleaned up.
Situation 3: You bought an older home
Many neighborhoods in Palm Beach County have homes from the mid-20th century or earlier, often with ductwork that has been modified over the years. When you move in, you may have no idea when the ducts were last cleaned.
What it usually needs: a look first. If registers and returns are coated, or you find debris inside, a cleaning makes sense as a fresh start. If the ducts look reasonably clean, you can hold off. Either way, have an HVAC contractor check the equipment, coil and drain pan.
Situation 4: Pets, pests or both
Homes with dogs and cats collect hair and dander on return grilles and in returns. Separately, rodents or insects sometimes find their way into attics and ducts, especially in older homes or after storm damage.
What it usually needs: for pets, clean return grilles often and check the filter more frequently. Cleaning may be worthwhile if hair builds up in the ducts themselves. For pests, the EPA lists infestation as one of the situations where cleaning may be warranted. Deal with the pest problem first, then clean.
Situation 5: Moisture, musty smells or mold
The AC smells musty, you've had a leak, or you see dark spots on vents or ceilings.
What it usually needs: not a duct cleaning, at least not first. Moisture problems usually start at the coil, drain pan, drain line or a leak. Call an HVAC contractor, and a mold professional if there's visible growth. The EPA says that wet or moldy duct insulation should be replaced rather than cleaned, and that mold will return if the moisture source isn't fixed. A cleaning may follow once that's done. We don't offer mold remediation or fogging treatments.
What South Florida homes should do every year
Even without a duct cleaning schedule, some tasks belong on the calendar:
- HVAC service, including cleaning the coil and drain pan, as the EPA suggests.
- Dryer vent cleaning, which the U.S. Fire Administration recommends at least once a year, or sooner if drying takes longer than normal. Unlike ducts, dryer vents collect lint with every load.
- Filter changes whenever the filter looks loaded. In heavy-use months, that may be more often than the package suggests.
- A quick look at registers and returns. If they're coated, it's a sign to look further.

The bottom line
In South Florida, the question isn't how many years it has been. It's whether there's a reason. Renovations, unknown history, pests and visible buildup are good reasons. A calendar alone isn't.
