HVAC System Testing

Maximize HVAC Efficiency: Our Expert Testing & Balancing

Testing, adjusting, and balancing (TAB) is an essential part of any heating, ventilating, and air conditioning (HVAC) installation. All facilities require the correct flow of air and water to provide optimum operating conditions, comfort levels, and energy efficiency available from building systems.

Since 1978, ViroCon’s staff of engineers and technicians has provided the best in TAB services. Unlike other firms, we utilize professional engineers in the field to test and adjust your system. Our engineering team has the knowledge and experience to make your HVAC systems work for you. We have the most advanced instrumentation and test equipment and are certified by the National Environmental Balancing Bureau (NEBB #2517).

Our careful attention to detail ensures that building HVAC systems perform as designed.

Our TAB experience lends to our expertise in related commissioning and troubleshooting projects. Our engineers are experts at TAB verification as well as diagnosing system problems and developing solutions. ViroCon’s expertise in TAB of HVAC systems is another way in which we make your facility work.

Sound & Vibration Testing

We are an NEBB-certified agency that provides sound and vibration monitoring and testing. Our engineers are experienced in troubleshooting noise and vibration problems. We can pinpoint problem sources and develop solutions for corrective action.

Noise control in building systems can be as critical as conditioning the building environment or providing uninterrupted power. Excessive noise and vibration from building systems can be a nuisance to occupants, cause early component failure, and damage to building contents (e.g., lab specimens).

Sound and vibration testing determines whether a building system machine or component operates within specified and acceptable vibration/noise limits. Vibration and noise sources are typically motors, fans, pumps, turbulent airflow, etc.

ViroCon is a NEBB Certified Firm
Comprised of licensed professional engineers who are NEBB Certified in Building Systems Commissioning and Testing, Adjusting and Balancing.
