TAB Services Inc.

Commissioning is performed by a third party independent company that records and documents specifications related to a project.

As a member of the AABC Commissioning Group, we help plan, organize, and facilitate the commissioning process for the owner of a certain project. Functional Performance Testing (FPT) of equipment and systems is at the heart of the commissioning process. Equipment operation during the tests is performed by the appropriate contractor or equipment manufacturer, but the responsibility for directing, witnessing, and documenting the tests rests with the commissioning authority.

We provide complete hydronic balancing for chilled water, hot water, condenser water, geothermal loop, and Process water systems.

Duct Air Leakage Testing (DALT) is a cost-effective method of potentially reducing an owner’s overall cost of operation. Testing is performed to maximize efficiency in an air handling system while minimizing the energy used to heat and cool an area.

We can test and certify the results of leakage testing in ducts and equipment casings having as little as a few cfm of leakage up to 1500+ cfm of leakage. We are capable of testing with pressures up to +16” w.c. and negative pressure testing down to -16” w.c.

Calculating the allowable leakage in accordance with SMACNA guidelines is included as part of the testing procedure. If necessary, smoke induction can be used to identify leakage areas in tested ductwork. After we determine the actual amount of air leakage, the mechanical contractor can do the necessary fixes to reach the allowable leakage rate.

The less leakage, the more efficient and cost-effective a system is, ultimately reducing energy costs.

LEED IEQ 3.2 2009 test methods

Our air quality test equipment measures for levels of carbon monoxide, carbon dioxide, nitric oxide, formaldehyde, and particulate matter in an indoor environment.

We offer seasonal performance testing to verify that the system as a whole is operating correctly when at or near peak high summer temperatures and peak low winter temperatures. Any deficiencies in the system are documented in a seasonal test & balance report, along with recommendations on how to best fix any problems found at the time.

We offer sound and vibration testing services to determine whether or not the levels are acceptable, and if not, to determine which specific unit or rotating component is causing a problem.

We offer stairwell pressurization tests to ensure that the system, as built, is operating as intended. The performance test consists of measuring the pressure differences across barriers under various conditions.

Checking for leaks on a Large Rooftop Air Handler is crucial for the units efficiency rating. Before the unit leaves the manufacturer, it is tested to insure factory settings. Once the unit is delivered and set up, it is retested to those settings verifying the units integrity.

As a third party to this procedure, we can test and certify the results of leakage testing in equipment casings having as little as a few cfm of leakage up to 1500+ cfm of leakage. We are capable of testing with pressures up to +16” w.c. and negative pressure testing down to -16” w.c.
