HVAC & Air Duct Mold Remediation in Lafayette, LA
HVAC mold remediation in Lafayette deals with the one part of a house that pulls water out of the air all summer long. Every hour the air conditioner runs, the coil turns humid air into water, the drain pan collects it and a condensate line carries it away. When the pan rusts, the line clogs or the ductwork sweats, growth starts inside the system and the smell travels to every room it serves. An independent assessor looks at the system and the rooms, and a separate contractor does the cleaning, replacement and air duct mold removal. Call (337) 294-0039.

Where HVAC mold grows in a Lafayette air-conditioning system
- Evaporator coil. Wet for most of the cooling season; dust stuck to the fins holds the moisture.
- Drain pan and condensate line. Standing water from a slow or blocked drain, a rusted pan or an air handler that is not level.
- Air handler cabinet and blower. Lined panels and the blower wheel collect damp dust.
- Ductwork. Lined duct, and flex duct whose outer jacket sweats where it runs through a hot attic or a crawl space.
- Registers and returns. Dark rings where cold supply air meets humid room air, often in rooms that are over-cooled.
Why Lafayette AC systems are prone to AC mold
Lafayette's cooling season is long and wet. The airport averages 90.7 days a year at 90°F or hotter (NOAA 1991-2020 normals), and from June through August the average dew point sits between 71.8°F and 73.9°F. Every hour of cooling wrings water out of that air onto the coil, and the pan and condensate line have to carry all of it away.
Oversized units make it worse. A system bigger than the house needs cools the air in short runs and shuts off before it has pulled much water out, so rooms feel cold and clammy at the same time.
How HVAC mold remediation and air duct mold removal are done
The independent assessment covers the system and the rooms: the coil, the pan, the drain, the cabinet, sample sections of duct, and the registers, with moisture readings in rooms that smell. A separate contractor then does the work in the scope:
- HVAC mold cleaning of the coil, cabinet and blower, and a new or re-pitched drain pan with the condensate line cleared.
- Air duct mold removal: hard ducts cleaned with HEPA vacuum and rotary agitation tools driven along the run; lined or flex duct with growth inside it replaced, because the lining cannot be cleaned.
- Remediation of any rooms the system affected.
- Correction of the cause: insulation on sweating duct, a drain that runs, or a unit sized and set so it removes moisture as well as heat.
Duct cleaning on its own is not HVAC mold remediation. Cleaning the ducts while a wet coil and a full pan keep feeding them only resets the clock. Louisiana keeps the assessor and the remediation contractor separate on any one property (La. R.S. 37:2158(A)(23)), and someone other than the contractor checks the system before it is put back in service.
HVAC mold remediation cost in Lafayette
Cleaning and treating the coil, pan, cabinet and blower, with the main ducts cleaned, sits at the lower end. A whole-house job with duct replaced and affected rooms remediated runs $6,000 to $20,000, depending on the size of the system, how much duct is replaced and how many rooms are involved. The assessment is $300 to $600, plus $50 to $100 for each air sample if samples are needed.

HVAC and air duct mold questions
Why does my house smell musty when the AC turns on?
Usually because something in the system stays wet: the coil, a pan that does not drain, or lined duct. The smell rides the air to every room. Call (337) 294-0039 to have the system assessed.
Is duct cleaning the same as HVAC mold remediation?
No. Cleaning ducts while the coil and pan stay wet only buys time. Remediation fixes the moisture and treats or replaces every part with growth. Call (337) 294-0039 to compare the two for your house.
Can moldy ductwork be cleaned or does it need replacing?
Hard metal duct can usually be cleaned. Lined duct and flex duct with growth inside are replaced, because their surfaces cannot be cleaned. Call (337) 294-0039 so sections can be checked.
What does air duct mold removal cost in Lafayette?
A whole-house job with duct replacement and room remediation runs $6,000 to $20,000; cleaning only the unit costs much less. Call (337) 294-0039 for a figure on your system.
Will a UV light stop mold in the AC?
A UV lamp at the coil can slow regrowth on that one surface, but it does nothing for a blocked drain, wet duct or growth that is already established. Call (337) 294-0039 before buying one as a fix.
Who checks the system after HVAC mold remediation?
Someone other than the contractor who did the work, before the system goes back into normal use. Call (337) 294-0039 to have that check included.
