HVAC Interview Question EN 01

In a pharma HVAC interview, you can expect questions that assess your technical knowledge of HVAC systems, including their design, operation, and maintenance. You may be asked about various types of HVAC equipment, such as chillers, boilers, air handlers, and exhaust systems, as well as their components and functions.

GMP Compliance: Good Manufacturing Practices (GMP) are critical in the pharmaceutical industry to ensure product quality and safety. Interviewers may ask about your understanding of GMP requirements and how they apply to HVAC systems in a pharma setting. You may be asked about clean room classifications, air changes per hour (ACPH), temperature and humidity control, and monitoring systems.
