10. Maintenance in Critical Environments

If you want to be sure your heating, ventilating and air conditioning (HVAC) system is safe, efficient and consistent in operation, the single best recommendation we can give you is to perform scheduled maintenance.

If you are not familiar with maintenance, it is worth your time getting up to speed quickly. Maintenance protects the return on your investment. It is a set of tasks by which you make sure your critical environment is operating the way it was designed. Regular maintenance is like going to the doctor for an annual check-up. It helps you catch things early, before your building ends up in Emergency, where you can spend 10 times as much fixing the problem.

Example of Maintenance Tasks

Objective: to check HVAC system air flows, sequence of operation and directional flow relationships in biological safety level 2 laboratory.

  • Dampers or air control valves operation
  • Airflow measurement stations are reading correctly, if not clean, calibrate or replace
  • Temperature, humidity, and pressure sensors are reading correctly, if not clean, calibrate or replace
  • Verify fume cupboard monitors/controllers are functioning properly
  • Air quality sensors are reading correctly, if not clean, calibrate or replace element
  • Verify control functions and sequences are controlling properly

In addition HVAC contractors must perform preventative maintenance to protect static pressure in variable air volume control systems. Click here for illustration of common tasks
