Air duct cleaning and duct repair in Cape Coral

When duct cleaning is worth paying for

The EPA's guidance is plainer than most of the ads. Duct cleaning has never been shown to actually prevent health problems. The EPA says to consider it when:

• There is substantial visible mold growth inside the ducts or on other parts of the system.
• Vermin (rodents or insects) are in the ducts.
• The ducts are clogged with so much dust and debris that it blows out of the supply registers into the house.

Outside those cases, I'd spend the money on a new filter, a clean coil and a working drain first. A dirty system is more often a filter problem than a duct problem.

The coupon that turns into a mold quote

A common pattern: a low-priced whole-house duct cleaning coupon, a technician who finds "mold" once inside, and a quote several times the coupon price for treatment. Sometimes the mold is real. Cape Coral is humid, and a system with a clogged drain or a wet air handler closet can grow it. But you should see it before you pay for it.

• The EPA says to ask the company to show you any mold they claim to have found. A photo of the inside of your own duct, not a stock image.
• The EPA does not certify duct cleaning companies, so a "certified by EPA" claim is not real.
• Be careful about chemical treatments. The EPA notes that no biocide is registered for use on fiberglass duct materials. Ask what product they plan to use and what it is registered for.
• The EPA also says to get estimates from more than one company.

Mold on the ducts usually has a moisture cause upstream. If you clean it and leave the cause, it comes back. Our page on musty smells and humidity covers the usual causes, and a clogged drain line is near the top of the list.

New AC, same old ducts

A frequent local question: the house got a new system last year and it is still dusty, so should the ducts be cleaned? Two things to know. A replacement usually reuses the existing ductwork, which in an older Cape Coral house may be as old as the house. And technicians on local forums are blunt that most household dust is not coming out of the ducts at all. Before paying for cleaning, check that the filter fits its slot with no gaps. Then ask whether the return side is pulling attic dust through a torn joint. A very restrictive filter isn't the fix either; it can choke airflow. If the ducts are old or moldy, pricing a duct replacement may make more sense than cleaning them.

Leaky attic ducts in slab homes

A typical Cape Coral house is single-story on a slab, so the ducts run through the attic. In August that attic is far hotter than the outdoor high, which averages 92°F at Page Field. A torn flex duct or a supply joint that pulled loose dumps cooled air into that space and pulls hot, wet attic air back in through leaks on the return side. Signs:

• One or two rooms that never cool while the rest of the house does.
• Weak airflow at registers far from the air handler.
• Higher bills with no change in how you set the thermostat.
• Insulation dust around return grilles.

The DOE's Energy Saver guide lists sealing ducts as one of the basic ways to cut cooling costs. Repairs range from resealing joints with mastic to replacing crushed or rotted runs. Hurricane damage counts too: if a storm opened the roof and the attic got wet, wet duct insulation should be inspected, and our after the hurricane page covers the rest of the system.

Duct work in Cape Coral can fall under the city's A/C Change Out permit, which covers replacing AC units and/or doing duct work. Ask the company whether your repair needs it.

What it costs

Air duct cleaning	$300 to $700, $500 average	Fixr
Typical AC repair, for comparison	$250 to $700, $375 average	Fixr

National figures, not a Cape Coral average and not our quote.

Duct repair is priced by what is found, so get it in writing after the technician has been in the attic. Ask whether the price includes sealing the air handler cabinet and the return plenum, since those leak as often as the ducts do.
