What to Do if You Find Mold in Your HVAC System?

The discovery of mold in your HVAC system can present a significant hazard to the occupants. It is of the utmost importance to address HVAC mold to contain the mold and prevent spores from spreading throughout the home. Due to the nature and design of residential HVAC systems, your health and indoor air quality can deteriorate quickly if the issue is left unresolved. Mitigating mold in HVAC systems requires a quick response and an effective remediation plan.

Is Mold Common in an HVAC System?

The purpose of the HVAC system is to control and moderate temperature and airflow. These systems are designed to create conditions unfavorable for mold growth, but the mechanisms themselves can provide an ideal environment for mold to colonize.

Common Causes of Mold in HVAC Systems

Dark and enclosed ductwork, paired with continuous moisture from condensation, offers the perfect breeding ground. These spaces also accumulate dust and organic debris, prime food sources for mold. Mold in HVAC systems is most commonly found in units lacking regular maintenance. Neglected HVAC systems are more likely to harbor dangerous mold infestations.

How Do I Get Rid of Mold in My HVAC System?

Attempting to remove mold from your HVAC system can be challenging. Before starting any mold removal, it is critical to take safety precautions.

First, shut down the HVAC system to prevent further distribution of mold spores. Next, wear proper personal protective equipment (PPE). Inhaling or touching mold spores can be dangerous. Minimum recommended PPE includes:

N-95 respirator
Gloves
Eye protection

Accessibility plays a key role in whether a homeowner can tackle the job or if professionals are needed. Small mold colonies in accessible areas may be managed as a DIY project. Steps for HVAC mold removal include:

Identify and eliminate the source of moisture (e.g., leaks, condensate pans, drain lines).
Clean mold from nonporous surfaces with a detergent solution.
Use a HEPA vacuum to remove mold and spores.
Replace any porous materials contaminated with mold, like filters and insulation.
Thoroughly dry the area and ensure proper ventilation.

However, professional HVAC mold remediation is recommended when:

Mold is not easily accessible
The infestation is large
Occupants have health conditions worsened by mold exposure

What Should You Expect For HVAC Mold Removal Cost?

So, how much does it cost to remove mold from an HVAC system?
HVAC mold removal cost varies depending on several factors:

Size and extent of the mold infestation
Accessibility of mold-contaminated areas
Type of mold involved
Specific HVAC components affected (e.g., air ducts, coils, insulation)
Need for replacement or repair of damaged parts

To get an accurate quote, a professional assessment by a licensed mold remediation company is essential.

Is Mold in Air Conditioners Harmful? Is It Safe to Use an AC with Mold?

If you suspect mold in your HVAC system, especially in your air conditioner, stop using it immediately. Mold in an AC unit is dangerous and can pose serious health risks.

Exposure to HVAC mold can trigger:

Respiratory issues
Allergic reactions
Asthma attacks

Some types of mold can even produce particularly harmful mycotoxins. Continued use of an air conditioner with mold will circulate spores throughout your home, worsening indoor air quality and spreading the infestation.
