HVAC & Air Duct Mold Remediation in Shreveport, LA
If the house smells musty a minute after the AC kicks on, or black specks keep coming back on the supply vents, the mold is probably inside the air conditioning system itself: on the coil, in the drain pan, in the air handler or along the duct runs. Because the system pushes air into every room, mold in the AC turns one wet part into a whole-house problem. HVAC and air duct mold remediation in Shreveport means cleaning or replacing the parts that grew it, treating the rooms it reached, and fixing the drainage or humidity that started it. Call (318) 666-4874.
Mold in the AC unit, the vents and the ducts
An air conditioner pulls water out of the air all summer long, and that water has to go somewhere. When it drains properly, the system stays clean. When it does not, these are the places mold shows up first.
The coil and the drain pan. The evaporator coil is cold and wet for months at a time. If the condensate line clogs, water sits in the pan and the coil and pan grow a dark film that the blower spreads.
The AC closet and the air handler cabinet. The insulation lining the cabinet soaks up moisture and dust. In hall closets and garages the unit can sweat on the outside too, which is how a musty AC closet starts.
Duct runs in the attic. Cold ducts running through a hot Shreveport attic sweat when the insulation wrap is torn or the seams leak. Flex duct and fiberglass duct board that get wet inside grow mold that cannot be cleaned out and has to be replaced.
The supply vents and the filter. Specks, fuzz or a dark ring around a grille is the growth arriving in the room. A filter that looks speckled on the clean side is another sign the source is upstream.
Who checks the system, and who cleans it
Louisiana does not allow the same company to both assess and remediate mold on one property, so the work is split in two. An independent mold assessor opens the air handler, looks at the coil, pan and a section of duct, and takes air samples in the rooms the system serves, compared against an outdoor sample. That report says what is growing, where, and how far it has spread.
The remediation crew then works from that report, and the independent assessor comes back at the end to test the air with the system running. Keeping the two apart means nobody is grading their own work. More on how assessments work is on the mold inspection and testing page.
How the AC and duct mold job is done
Seal the system. The unit is shut down and the supply and return openings are covered so nothing gets blown through the house while the work goes on.
Clean the parts that can be cleaned. The coil, drain pan, cabinet and blower wheel are cleaned and treated with a product made for HVAC equipment. Metal duct runs are agitated and vacuumed with filtered equipment.
Replace the parts that cannot. Moldy duct board, flex duct and cabinet liner come out and new runs go in, with the openings sealed so the attic does not get contaminated on the way out.
Treat the rooms it reached. Where growth has started on ceilings or walls around the vents, those areas are handled under containment, the same way as any mold remediation job.
Stop it starting again. The condensate line is cleared and trapped, the pan sloped to drain, attic ducts sealed and wrapped, and indoor humidity brought down, whether that means a correctly sized system or a dehumidifier.
Most AC mold jobs take three days to a week, depending on how much duct is replaced and how many rooms are involved.
Duct cleaning or HVAC mold remediation?
A duct-cleaning crew vacuums dust out of the ducts. That is the right service when the ducts are simply dusty, and it costs less. It is not built for mold: it does not open and treat the air handler, replace moldy duct board, deal with the rooms, or fix the drain that caused it, and nobody tests the air afterwards. The assessment tells you which of the two you need.
What AC mold removal costs in Shreveport
Cleaning and treating the coil, pan, cabinet and blower, with the metal ducts cleaned, sits at the low end, usually a few thousand dollars. A whole-house job with duct replacement and the affected rooms treated runs $6,000 to $20,000, depending on the size of the system, how much duct comes out and how many rooms are involved. The assessment is typically $300 to $600, plus $50 to $100 for each air sample. Every price on the site is on the mold removal cost page.

Getting the AC looked at
Call (318) 666-4874 and tell us what you notice, which rooms it is in, and roughly how old the system is. If it is easier to write it down, use the callback form below or the contact page. If the mold turned up in the attic as well, see attic mold removal; for offices and rentals, see commercial mold remediation.
Mold in the AC: what Shreveport homeowners ask
What should I do about mold in my AC vents?
Treat the vents as the place the mold is showing up, not where it started. Specks or fuzz on a supply grille usually mean something upstream is wet: the coil, the drain pan or a sweating duct. Have the air handler and a section of duct opened and checked so the source is found before anything is cleaned.

Can a duct cleaning company get rid of mold in the AC unit?
Not on its own. Duct cleaning removes dust from the ducts, but it does not treat the coil and cabinet, replace moldy duct board, deal with the rooms, or fix the drainage behind it. If the system only has dust, duct cleaning is the cheaper and right choice; if there is mold, it is a remediation job.

How much does it cost to remove mold from an AC system in Shreveport?
Cleaning and treating the system usually runs a few thousand dollars. A whole house with duct replacement and the affected rooms treated runs $6,000 to $20,000. The assessment is typically $300 to $600 plus $50 to $100 per air sample, and the written price comes after it.

Who tests the system before and after the work?
An independent mold assessor, not the crew doing the removal. Louisiana does not allow one company to both assess and remediate the same property, so the first inspection, the air samples and the final air test come from a separate firm.

How long does an AC mold job take?
Usually three days to a week. Cleaning the equipment is the quick part; replacing duct runs and treating the rooms takes longer, and the final air test happens with the system running.

Should I keep running the air conditioning?
If you know there is mold in the system, run it as little as you can until it is dealt with, because every cycle moves spores around the house. In a Shreveport summer that is hard to do for long, which is why it is worth getting the system looked at quickly.

Does the contractor need a Louisiana license for AC mold remediation?
For mold remediation jobs valued at $7,500 or more, Louisiana requires the contractor to hold a mold remediation license from the State Licensing Board for Contractors. Ask to see it, and proof of insurance, before the work starts. Swapping out ducts or AC equipment may also need a mechanical permit; the City of Shreveport, or the parish outside city limits, decides.

Will a UV light keep mold out of my AC?
A UV light at the coil helps keep the coil itself clean. It does nothing for the ducts or the rooms, and it will not fix a clogged drain or a sweating duct. It can be part of the fix, but it is not the fix.
