We provide consulting services to architectural and engineering firms for topics related to our areas of expertise. Specifically, mold avoidance, moisture and humidity problems, dehumidification, humidification, drying of materials; and humidity and moisture measurement, monitoring and control. We work with building owners and property managers to diagnose and recommend solutions to complex problems involving the interaction between the HVAC systems and the building enclosure.

Typical examples of HVAC-building enclosure problems include ice dams, mold inside interior walls and humidity problems caused by kitchen exhaust and by intermittent operation of seasonally-occupied buildings. To be clear, we are not licensed professional engineers, and we do not provide HVAC design services. Instead, we serve as diagnostic consultants and specialized technical design consultants to owners, consultants: engineers, architects, and HVAC designers who need to understand humidity-related HVAC technologies at the design stage, and classic problems that occur with their operation and interaction with the building over time.
