Alaska Air Balancing offers several services for the successful completion of your project.

Air Balancing
Hydronic Balancing
Building Acoustics Measurements
Duct Leakage Test

Air balancing is a method of testing your heating and cooling systems to ensure airflow is properly distributed.

Air balancing will ensure that the system is performing the way it is designed to and that it is operating as efficiently as possible. Air balancing helps to provide comfort for the occupants as well as a great level of manageable temperature control.

Hydronic balancing is the process of optimizing the distribution of fluid throughout a buildings hydronic heating or cooling system by equalizing the system pressure to provide optimum energy efficiency and minimize operational costs.


In a properly balanced system every heating or cooling element is set to receive the proper amount of fluid in order to generate the required amount of heating or cooling.

AAB has extensive experience in acoustic measurements in both commercial and residential buildings. We are able to perform a wide range of acoustic measurements to suit a clients needs.

We have experience in the following

  • Reverberation Time (RT60) Measurements

  • Sound Transmission Class (STC) / Noise Isolation Class (NIC) Measurements

  • Noise Criteria (NC) and Room Criteria (RC) Measurements

  • Vibration Testing

Duct Air Leakage Testing (DALT) is an extremely important service that will measure the airtightness of your HVAC ductwork. Leaks in ductwork is a major source of wasted energy in a building and contributes to indoor air quality, room pressurization issues, and
noise issues.

Being able to identify those leaks so that they can be repaired is a great way to improve HVAC efficiency and save money.

Critical Space Testing
Building Envelope Testing
Thermal Imaging
Fume Hood Certification

Critical Space Testing (CST) is a maintenance and operations process defined as the measurement of airflow and pressure relationships for spaces that are deemed critical to providing patient care.

CST is typically performed within health care facilities and provides facility managers, maintenance personnel, hospital staff and patients confidence in the operation of the HVAC equipment serving operating rooms, isolation rooms and many other critical spaces.

Building envelope testing is the process of testing both the interior and exterior of a building structure to determine if there are any air or thermal leaks. 

The impact of air leakage, in which uncontrolled air leakage enters or leaves a building, imposes a significant
energy penalty on the building. In addition to the direct energy penalty imposed by air leakage, there are other associated problems that usually occur, these include:

  • Occupant discomfort due to drafts

  • Degradation of the building fabric due to interstitial condensation

  • Poor indoor air quality due to the ingress of fumes, dust, molds, etc

  • The inability to achieve the required pressure conditions in pressure sensitive areas

AAB is Level 2 Thermography certified and specializes in building heat loss. Thermographic building surveys can provide many useful insights. 

Thermal Imaging can be used in conjunction with Blower Door Testing while the building is in
either a positive or negative pressure condition. In this mode we are able to detect the effectiveness of insulation as a barrier to heat loss; occurrences of thermal bridging; sources of air leakage; moisture and damp areas and other hidden components.

Chemical fume hoods are one of the most critical items of safety equipment present within the laboratory. It is vitally important they are properly maintained.


Chemical fume hoods serve to control the accumulation of toxic, flammable, and offensive vapors by preventing their escape into the laboratory atmosphere. Fume hoods provide physical isolation and containment of chemicals and their reactions, thus serving as a protective barrier between laboratory personnel and the chemical or chemical process within the hood.

We are able to provide an ASHRAE 110 test and certify that it is operating correctly. The ASHRAE 110 test includes:


  • Face Velocity Measurement

  • Smoke Visualization Test
