PTAC Unit Myth 3 of 3 - Dehumidification

This is a 3 part Vlog series of, “The 3 Myths of PTAC Units.”

Over the past 30 years, building experts at Liberty Building Forensics Group (LBFG) have investigated hundreds of moisture problems (involving thousands of guest rooms) and in the process, have observed three repetitive assumptions that appear to be completely ignored by the building industry:

  1. PTAC units cannot effectively ventilate interior spaces.

  2. PTAC units cannot effectively pressurize hotel guest rooms.

  3. PTAC units are often ineffective in dehumidifying hotel guest rooms, especially when outside conditions are hot and humid.

The Mold Tree - A Predictability Chart to Help Avoid Mold and Moisture Problems

Why are we still seeing the same PTAC-related mold and moisture problems today as we saw in the 1980’s? We need to become more cognizant of the basic principles for low-cost systems in very simple applications. Liberty’s team has developed a diagram, using their 30+ years of experience in building forensics, that will help you avoid the potential risks of a catastrophic mold and moisture problem in your PTAC-equipped room.
