HVAC & Air Duct Mold Remediation in Metairie, LA
HVAC mold remediation in Metairie deals with growth inside the air-conditioning system itself: on the evaporator coil, in a drain pan that does not empty, on the air handler's lining and inside the ductwork, where every cycle can carry spores and odor to the rooms the system serves. The Louisiana Department of Health says mold growing inside an HVAC system is a job for professionals. An independent assessment establishes where in the system the growth is; a separate contractor cleans or replaces those parts. Call (504) 360-1797 to have the system checked.
HVAC mold in Metairie: coil, pan, handler and ducts
An air conditioner removes water from the air as it cools it, so its cold coil and the pan under it are wet for much of the year. If the pan drains slowly, the condensate line clogs, or the handler sits in a hot attic or closet, those surfaces stay damp long enough to grow mold. From there, dust and spores move into the supply plenum and the ducts. Signs include a musty smell when the system starts, dark residue on supply registers, or growth visible when the handler panel is opened.
Why AC mold takes hold in Metairie
The air the system pulls in is heavy with water: at the NOAA station in Kenner the average dew point stays above 70°F from June through September. That keeps coils and pans wet and puts condensation on duct runs in hot attics and crawl spaces where insulation has gaps.
Storms add another route. After Hurricane Ida in 2021, about 198,000 Jefferson Parish Entergy customers were still without power five days later, and Entergy's estimate for Metairie and Kenner was September 8. Houses closed up in late-summer heat with no air conditioning for days collected moisture in ducts and handlers, and growth from that period can still be in a system that was simply switched back on.
How HVAC and air duct mold removal works
Assessment. The inspector opens the handler, checks the coil, pan and condensate line, looks inside the ductwork at accessible points, and decides whether rooms served by the system need checking too.
System off and sealed. The system is shut down for the work, and registers are covered so cleaning does not blow debris into rooms.
Handler and coil. The coil and blower are cleaned, the drain pan is cleaned or replaced, the condensate line is cleared, and contaminated internal lining is removed.
Ducts. Rigid metal ducts are cleaned under negative air; flex duct and duct board with growth in the lining are usually replaced, since that material cannot be cleaned reliably.
The cause. Drainage, insulation on cold surfaces and, where needed, sizing or humidity control are corrected so the system dries properly in use.
Air duct mold: clean, seal or replace
Routine air duct cleaning removes dust; it is not a fix for mold growing on duct lining or in the handler. Spraying a coating over growth inside ducts leaves the growth in place. The decision between cleaning a run and replacing it depends on the duct material and how far growth has reached, and the written scope should name each run and what happens to it.
HVAC mold and the Louisiana two-firm rule
Louisiana does not let a mold remediation contractor both assess and remediate one property, or own part of both companies (La. R.S. 37:2158(A)(23)(c)-(d)). The system is assessed by one firm; the remediation of the handler and ducts is carried out by another, with an HVAC technician involved where equipment has to be repaired or replaced.
HVAC and duct mold removal cost
For the AC system and ducts of a whole house the published price table gives $7,500 to $25,000. Where only the handler, coil and pan are involved the figure sits toward the bottom; replacing long runs of flex duct, or treating rooms the system has affected, pushes it up. The assessment with a written report is $300 to $650, plus $75 to $150 when the handler is in the attic or crawl space.
That range is for planning; your price is set in writing after the system has been opened and looked at. More on the mold removal cost page.
Booking an HVAC mold assessment in Metairie
Call (504) 360-1797 and say where the air handler is, how old the system is roughly, whether the smell is in every room or just some, and whether the house was without power after a storm. The callback form below and the contact page are alternatives.
HVAC and air duct mold questions
What should I do about mold in my AC ducts?
Have the system assessed before anyone sprays or fogs it: the source is usually at the coil, pan or handler, and duct lining with growth in it often needs replacing rather than cleaning. The written scope then goes to a separate remediation contractor. To book an HVAC assessment, call (504) 360-1797.
What is the average cost to remove mold?
For a whole-house AC system and ducts the published range is $7,500 to $25,000; work limited to the handler, coil and pan sits at the low end. The assessment is $300 to $650 beforehand. For a written figure on your system, call (504) 360-1797.
Is a mold inspection worth it?
For HVAC mold it usually is, because the musty smell can come from the coil, the pan, the ducts or a room the air passes through, and each needs a different fix. An independent inspection tells you which before money is spent. Request one on (504) 360-1797.
Who handles mold in a rented house, the renter or the landlord?
Air-conditioning equipment is usually the owner's responsibility under a lease, but the lease itself decides, and so does whether filters and drains were maintained. A written assessment of the system gives tenant and landlord the same record. Either can call (504) 360-1797.
Will my insurance pay for mold remediation?
Mold from routine condensation in an AC system is often excluded, while damage following a covered event may be treated differently; your insurer decides. The assessment report and photos record the condition of the handler and ducts for any claim. To have that record made, call (504) 360-1797.
Who removes mold from homes?
For an air-conditioning system, a mold remediation contractor does the handler and duct work, often with an HVAC technician for equipment repairs, after an independent assessor has set the scope. Louisiana keeps the assessor and the remediator separate. For a system in Metairie or Kenner, call (504) 360-1797.
