Testing and Balancing, Air and Hydronic
Environmental systems are designed to provide a proper balance of air movement, temperature and humidity to create a comfortable and healthy indoor environment.
In order for these systems to perform as designed, testing and balancing is needed. Without proper TAB (testing, adjusting and balancing), an environmental system can rarely meet all the objectives set by the design engineer. Research has proven that proper TAB will improve HVAC performance in terms of comfort and health, reduce maintenance costs by uncovering potential problems and provide 5 to 15% savings in energy costs.
Cleanroom Performance Testing (CPT)
Air Systems is now NEBB Certified in Cleanroom Performance Testing.
We are the only firm located in Upstate New York with this internationally recognized and respected distinction.
CPT is the act of evaluating the performance of a cleanroom by performing a series of defined tests with prescribed procedures and reporting requirements.
Air Systems possesses the skill to work through the testing process and provide a detailed analysis at the project’s completion.
We can assist in resolving any non-conformance issues to minimize a facilities downtime and assure a successful certification process.
Our firm follows NEBB’s Procedural Standard for Certified Testing of Cleanrooms, as well as International Standards ISO 14644-1:2015, ISO 14644-2:2015, and ISO 14633-3:2005. IEST recommended practices are used in order to ensure proper compliance.
Primary cleanroom tests include:
Airflow Velocity, Volume and Uniformity
HEPA Filter Installation Leak Test
Airborne Particle Count Cleanliness Classification
Optional Tests include:
Airflow Parallelism (visualization)
Lighting Level and Uniformity
Temperature and Humidity Uniformity
Air Change Rate (ACH)
Bench Scan Filter Leak Tests
Annual and Periodic Testing
OSHA requires annual testing of laboratory fume hoods. Air Systems Balancing tests the face velocity at multiple points to determine if the fume hood is working as intended. If it is not, we take the steps necessary to help resolve the problem. Air Systems Balancing can test and balance any kind of exhaust system, including: paint spray booths and dust collection systems.
Hospital isolation rooms, operating rooms and nuclear imaging rooms should be tested on a scheduled basis to verify the required air changes per hour and room pressurization. Air Systems Balancing performs this work for several hospitals to help protect public health.
Building Systems Commissioning
Building Systems Commissioning is a disciplined procedure designed to provide a building owner with a completed building operating as designed and specified. Its intent is to furnish a building owner with a high degree of assurance that equipment and systems have been installed in the prescribed manner and will operate according to the performance guidelines. Air Systems Balancing is a NEBB & ICB/TABB Certified Commissioning Administrator and is prepared to offer a full range of Commissioning services.
Fire and Smoke Damper Testing
Fire dampers, smoke dampers, and combination fire smoke dampers are hidden from view but they play an important role in passive fire protection by preventing fire and smoke from spreading through a facility.
The significant protection capabilities of fire dampers to life and property are now widely recognized by facility managers throughout the United States. More and more Authorities Having Jurisdiction (AHJs) and building owners are requiring fire dampers to be operational tested and maintained on a regular basis.
AHJs are requiring operational tests to determine if the damper will function when needed in order to resist the spread of fire. All the dampers installed in a building must be tested prior to occupancy and again one year later under normal operating conditions. After that, fire damper inspection and testing requirements are every four years and every six years for healthcare facilities.
During fire damper testing, our certified technicians make sure that the dampers open and close as designed. Operational testing normally involves removing the fusible link and letting the damper close. Once the damper has proven to close, it is reopened and the fuse link reinstalled.
We provide our customers with a comprehensive fire damper analysis report that notes all the important information about each of their devices. No matter what service you require, we help to keep you compliant with JCAHO and NFPA fire damper testing, inspection, and maintenance requirements.
Air Systems possesses the skills and instruments necessary to perform periodic on-site calibration of the critical devices controlling your HVAC systems. Calibration assures your systems are operating at optimum efficiency which translates to fewer trouble calls and maintenance issues. Devices that we specialize include but are not limited to:
Airflow stations – supply, return and outside air
Hydronic Flow Stations (water & glycol), Ultrasonic Flow Measurement
Temperature transmitters – air and hydronic, Pressure transmitters
CO2 meters used for demand control ventilation (DCV)
Controls Integration (with support from controls contractor)
Duct Leakage and Pressure Testing
Air Systems Balancing has the equipment and experience to test for duct leakage. We can test to very low loss systems at high pressures, such as for a process.
Indoor Air Quality
In this day and age building occupants are much more educated about IAQ. They are more demanding than just a few years ago. Even minor temperature and humidity swings can lead to complaints. Lack of proper ventilation can lead to fatigue, lost employee productivity and increases in the number of sick days.
Air Systems Balancing technicians set the required air volumes at all points of the system to assure that building occupants are not only comfortable, but breathing the proper amount of fresh outside air.
