Quick answer

Removal of mold in ductwork, coils, and air handlers, with the condensation and humidity problems that feed it corrected.

When mold grows inside an HVAC system, the problem is not contained to one room. Every time the system runs, air moves across coils and through ductwork, so growth in the air handler or ducts can distribute spores throughout the home. HVAC systems are prone to mold because cooling produces condensation. Cold coils, drain pans that do not drain properly, and ductwork running through humid spaces all create the damp conditions mold needs, which is especially relevant in Atlanta where humidity and cooling loads are high for much of the year. We remove mold from the affected components and address the condensation and humidity behind it, because cleaning the ducts without fixing the moisture just lets the mold come back.

What Our Air Duct and HVAC Mold Removal Includes

Inspect the system for growth and moisture

We check the components where HVAC mold typically appears: the air handler and blower, the cooling coil and drain pan, and the supply and return ductwork. The EPA notes that if there is mold in the HVAC system, the system should not run until it has been cleaned, to avoid spreading spores through the home.

Remove mold from coils, pans, and the air handler

Hard, non-porous components like coils, drain pans, and metal duct interiors are cleaned. Porous parts that have absorbed mold, such as contaminated insulation, fiberglass duct board, or a moldy duct liner, generally cannot be fully cleaned and are removed and replaced.

Address ducts and registers

Where ductwork is affected, we clean accessible non-porous ducts and replace porous duct material that cannot be cleaned. The principle is the same as elsewhere: physically remove the growth rather than fogging a product through the system and calling it done.

Correct the condensation and humidity source

A clogged condensate drain, an oversized system that short-cycles, ductwork sweating in a humid attic or crawl space, or whole-home humidity above the recommended 30 to 50 percent range can all keep an HVAC system damp. We identify the moisture source so the problem does not simply return after cleaning.

How It Works

Inspect and identify the moisture

We inspect the air handler, coils, drain pan, and ductwork for mold and trace the condensation or humidity source feeding it.

Take the system offline and contain

Because running the system spreads spores, we have it shut down during the work and contain the affected components and registers with HEPA filtration.

Remove and clean

Non-porous coils, pans, and metal ducts are cleaned, while porous insulation, duct board, or liner that cannot be cleaned is removed and replaced.

Fix the moisture source

We correct or recommend fixes for the condensate drain, sweating ductwork, or humidity problem so the system stays dry and mold is far less likely to return.

Document and verify

You receive written records of the work, and where it adds value, post-remediation testing helps confirm the area has returned to a normal condition.

Signs This May Be What You Need

A musty smell that gets stronger when the heating or cooling runs
Visible mold around supply registers, vents, or the air handler
Allergy-like symptoms that ease when you leave the home
Standing water or overflow at the condensate drain pan
Ductwork sweating or staining in a humid attic or crawl space
Mold returning shortly after a previous duct cleaning

Frequently Asked Questions

How does mold get into an HVAC system?

Cooling creates condensation, and that moisture is what mold needs. Cold coils, a drain pan that does not drain properly, and ductwork passing through humid attics or crawl spaces all stay damp, especially during Atlanta summers. Dust drawn through the system gives mold something to grow on. Until the condensation or humidity source is corrected, cleaning the system tends to be temporary.

Can mold in my ducts spread through the whole house?

Yes, that is the main concern. When the system runs, air moves across the coils and through the ductwork, so mold in the air handler or ducts can distribute spores to every room the system serves. The EPA advises not running an HVAC system that has known mold until it has been cleaned, precisely to avoid spreading it.

Is duct cleaning the same as HVAC mold remediation?

Not quite. Routine duct cleaning removes dust and debris, while remediation removes mold growth, replaces porous components that cannot be cleaned, and corrects the moisture source that caused it. Fogging or cleaning ducts without addressing the condensation problem usually leaves the conditions that grew the mold in place, so it comes back.

Do you have to replace my ductwork to remove the mold?

It depends on the materials. Hard, non-porous metal ducts, coils, and drain pans can usually be cleaned. Porous components like fiberglass duct board, internal duct liner, and contaminated insulation generally cannot be fully cleaned and are removed and replaced. We scope replacement to what is actually affected rather than swapping out the whole system by default.

Cost and Insurance

What affects the cost?

Every situation is different, so we do not quote a price before we know what we are dealing with. Cost depends on the size of the affected area, how much material has to be removed, how hard the growth or moisture is to reach, the type and extent of containment needed, and any moisture repairs behind the problem. You get a written estimate after an inspection, so the scope and what is included are clear before any work begins.

Will insurance cover it?

It depends on your policy and the cause. Sudden and accidental events, such as a burst pipe, are more often covered, while gradual leaks, long-term seepage, neglected maintenance, and flooding are commonly excluded or need separate coverage, and many policies cap mold-related costs. We cannot promise what your policy will pay, so review your own policy and speak with your insurer about your situation. We can provide documentation of the conditions we find and the work performed to support a claim.
