The Florida "M-Word" – Legal Boundaries & Tech Communication - Short #299 · HVAC School - For Techs, By Techs summary

Key takeaways

HVAC contractors in Florida must be cautious when addressing mold, as they are limited by law from diagnosing or remediating beyond a small size without proper certifications.
Proper identification of mold requires laboratory testing and specialist training—visual guesses or smell are not sufficient or legal equivalents.
Building and environmental laws aim to prevent scare tactics and protect consumers from unqualified contractors making false claims about 'toxic mold'.
Contractors should focus on moisture management, coil cleaning, and basic maintenance, and collaborate with licensed professionals for mold assessment and remediation.
Understanding the specific types of mold and their behavior helps create awareness but does not replace certified testing and diagnosis.

Summary

Legal Boundaries and Communication Regarding Mold in Florida

This section discusses the legal limitations HVAC technicians face when it comes to diagnosing, discussing, and handling mold issues in Florida. Due to strict laws, HVAC contractors cannot legally diagnose or remediate mold beyond a certain size (more than 10 contiguous square feet) without proper certification and laboratory testing. Essentially, the law aims to prevent scare tactics and false claims, especially by unqualified contractors. The speaker emphasizes that while contractors encounter mold-related issues regularly, their role is limited to maintenance and cleaning—no formal diagnosis or labeling as 'mold' unless a certified assessor is involved. The importance of understanding these legal boundaries and respecting the professional scope is stressed to ensure proper handling and ethical practice.

The Science of Mold and Its Identification Challenges

In this section, the discussion moves to the scientific aspects of mold, including common types such as Cladosporium, Aspergillus, Penicillium, and Stachybotrys. The speaker highlights that identifying specific mold types typically requires laboratory analysis and specialist training, which HVAC contractors generally do not possess. The conversation explains that outside conditions greatly influence indoor mold presence, and that the spores found inside often originate from outside. The importance of proper sampling and lab testing, rather than visual or smell-based guesses, is underscored. Additionally, the challenges in distinguish mold types and understanding their health impacts are acknowledged, emphasizing that exact identification is complex and best left to licensed professionals.

Practical Implications for HVAC Professionals and Recommendations

This final section provides practical guidance for HVAC contractors. It stresses the importance of staying educated on mold-related laws and scientific facts but also recognizes the limits of an HVAC tech's role. Contractors should avoid making definitive statements or diagnoses about mold unless qualified, and should focus on moisture control, coil cleaning, and basic maintenance. The speaker advocates for collaboration with certified mold assessors when necessary, and warns against using the 'mold' label as a scare tactic. The overarching message is that HVAC professionals must respect legal boundaries, understand the science, and act ethically to maintain trust and compliance.

Show notes

In this short podcast episode, Bryan and Roman talk about Florida law and how it relates to the "M-word" (mold) and the legal boundaries our techs must respect when they communicate with customers. HVAC School and Kalos are NOT mold experts, but we have experience as HVAC professionals who encounter suspicious microbial growth in our market (and cannot diagnose or remediate mold).

We cannot use the word "mold" because "mold" MUST be diagnosed by a certified mold assessor via laboratory testing according to Florida law. A guess based on sight does NOT qualify as a diagnosis; it is the equivalent of diagnosing a compressor failure as acid contamination without a test that proves the presence of acid. Residential property owners, however, are allowed to identify, remediate, and speak freely about mold in their own homes (which Roman can do because he hired mold assessors and remediators in his home).

Florida limits HVAC contractors from diagnosing mold (or removing more than 10 contiguous square feet while removing, maintaining, or installing equipment) to prevent scare tactics in sales, such as by diagnosing "toxic mold" in a drain, or to sweep larger problems under the rug. There are also many different mold types that have specific characteristics that can only be identified by an assessor; HVAC contractors are not trained to recognize those. However, mold is part of our work whenever we clean coils, HVAC units distribute air (which contains mold spores from outside), and we manage moisture (which contributes to fungal growth).

Mold assessors also have specific diagnostic tools and send lab samples. HVAC contractors don't have those resources, training, or certification. As HVAC contractors, need to be educated on mold, but we also need to understand our limitations; we can't diagnose it or make decisions for customers.
