Technician cleaning an evaporator coil inside an open air handler

HVAC Mold Cleaning

Why AC systems in Miami get musty

Your air conditioner cools air by passing it over a cold coil, and in Miami’s humidity that coil is wet much of the time. Water drips into the drain pan, and the air handler cabinet stays damp. When dust and organic debris settle on those wet surfaces, they can support microbial growth. That’s one of the most common causes of the musty smell people notice when the AC turns on.

Our HVAC mold cleaning service targets those areas: the evaporator coil, drain pan, blower, air handler cabinet, plenums and accessible ductwork where buildup is present. We clean the affected surfaces, apply an antimicrobial product where appropriate, and point out moisture problems we see so they can be corrected.

For general system cleaning without odor or microbial concerns, see HVAC cleaning. For odors in the ductwork only, air duct sanitizing may be enough.

What’s included

Areas we clean

01

Evaporator coil

The wet coil surface where buildup often starts.

02

Drain pan & condensate line

Standing water and sludge in the pan, and a slow or clogged drain.

03

Blower wheel & housing

Buildup carried from the coil area onto the fan blades.

04

Air handler cabinet

Interior panels and surfaces inside the unit.

05

Plenums & accessible ductwork

The plenums and the duct sections closest to the equipment.

Warning signs

Signs worth having checked

  • A musty or mildew-like smell when the AC starts
  • Dark buildup on supply registers or around vents, which could be dust or something else
  • Water standing in the drain pan or overflowing
  • Condensation or sweating on the air handler or nearby ducts
  • The AC was off for a long stretch, such as summer travel or after a storm
  • Indoor humidity that stays high even with the AC running

The benefits

What this service can and can’t do

Removes visible buildup

Buildup is cleaned from the AC components and accessible ductwork we work on.

Can reduce musty odors

When the odor comes from buildup in the HVAC system, cleaning often helps.

Highlights moisture sources

Fixing the moisture problem is key to keeping buildup from returning.

Honest limits

We don’t test for mold, and cleaning isn’t a guarantee that all growth is gone or that health symptoms will change.

Our process

How our HVAC mold cleaning works

  1. 01

    Discuss & inspect

    We talk through your concerns and inspect the accessible components and ductwork.

  2. 02

    Protect the area

    The work area around the air handler is protected before cleaning begins.

  3. 03

    Clean affected components

    Coil, drain pan, blower, cabinet and plenums are cleaned as needed.

  4. 04

    Antimicrobial application

    Where appropriate, a professional antimicrobial product is applied according to label directions.

  5. 05

    Moisture notes

    We point out moisture sources we see, such as a clogged drain or sweating duct, so they can be fixed.

Good to know

Important to know

Not every dirty duct or vent contains mold. Most buildup is ordinary dust and debris. Mold also can’t be identified just by looking; confirming it requires sampling and lab analysis by a qualified professional. Purix does not provide mold testing.

This service covers cleaning of HVAC components and accessible ductwork. If you suspect growth on walls, ceilings, insulation or other building materials, or if growth is widespread, we recommend contacting a qualified mold professional.

Do you test for mold?

No. We clean HVAC components and accessible ductwork. If you want to confirm whether mold is present, or identify what kind, that requires testing by a qualified professional.

Can you tell if it’s mold just by looking?

No. Dark buildup can be dust, debris or microbial growth, and it can’t be confirmed visually. We describe what we see and clean the affected components.

Will cleaning get rid of the musty smell?

If the smell comes from buildup on the coil, drain pan, blower or nearby ductwork, cleaning often helps. If an underlying moisture problem isn’t fixed, the smell can return.

Does every dirty AC duct have mold?

No. Most duct buildup is ordinary dust, lint and debris. Microbial growth is more likely where there’s ongoing moisture, which is why we focus on the wet components of the system.

How can I keep it from coming back?

Keep the condensate drain flowing, replace filters on schedule, avoid shutting the AC off for long periods in humid weather, and have sweating or leaking ductwork repaired.
