“As the leader when it comes to testing, adjusting, and balancing, we at Massive Testing and Balancing seek to create a reliable customer relationship through clear communication and top-notch performance to ensure your satisfaction. We always strive to provide superb service to each project, and an excellent experience for customers large and small.”

Testing & Balancing of Hydronic Systems

This is the regulating of design airflow and hydronic volumes to achieve the proper flow rates, and ventilation for each designated area/room through the project scope.

ASHRAE 110 Fume Hood Certification

Just after the fume hood is installed and prior to its first use, the hood must be set up with the proper face velocity and airflow rate, so that it can effectively exhaust any fumes when in use. Once this step is completed, the ASHRAE 110 certification tests can be performed.

HVAC Survey’s

This is work that provides a baseline measurement of the system and pieces of existing equipment for a specific building. Also, this provides an opportunity to trouble shoot any issues with this existing equipment.

Isolation Room Certification

This involves the testing and regulation of airflow in an isolation room, to make sure that the room has the proper air change rates, and also pressurization.

Ductwork and Unit Casing Leakage Testing

The unit or ductwork has an allowable leakage rate when this testing is required, and this is based off a specific system pressure. The unit/duct involved is blown up to the specified “test pressure” and is then tested for the leakage rate. The unit must be below the specified leakage rate (cfm) in order to pass.

Commissioning Services

This is the verification of flows and proper set up of equipment to make sure the customer’s needs and wishes are satisfied. Commissioning is when a specified percentage of the jobs equipment and systems are verified by checking the accuracy and consistency of airflow rates, unit operations, hydronic flows, and other aspects of the balancing and HVAC systems.

Cleanroom Certification Testing

This is testing your cleanroom and its equipment to the appropriate industry standards. Using Calibrated NIST traceable equipment, we will verify and document that your site and equipment are in compliance and functioning as intended. Certification Services are performed on an Annual/Biannual cycle as needed and a digital copy of all findings are provided.

HEPA Filter Leak Testing

This is testing your HEPA Filter for both Airflow and the verification of any leaks. Using Calibrated NIST traceable equipment, we will measure the filters airflow and then introduce an Aerosol upstream of the filter and check for any leaks downstream. Potential repair and replacement services are available, and a digital copy of all findings are provided.

Blower Door Test

TA blower door test is used on buildings in order to quantify the amount of air leakage through its enclosure. During this test, a calibrated fan is installed in a sealed doorway(to the exterior) while all the other openings to the exterior are closed.


Testing is the use of specialized and calibrated instruments to measure temperatures, pressures, rotational speeds, electrical characteristics, velocities, and air and water quantities for an evaluation of equipment and system performance.  Read more.


Adjusting is the final setting of balancing devices such as dampers and valves, adjusting fan speeds and pump impeller sizes, in addition to automatic control devices such as thermostats and pressure controllers to achieve maximum specified system performance and efficiency during normal operation.

Balancing is the methodical regulation of system fluid flows (air or water) through the use of acceptable procedures to achieve the desired or specified airflow or water flow. Read more. Read more.
