HVAC Balancing
Testing, Adjusting and Balancing (TAB) allows us to adjust the environmental settings of your building to achieve optimal comfort that meets the standards for the heating, ventilation and air conditioning (HVAC) systems.
We use state-of-the-art instruments to measure the performance of the HVAC system components. The field data is analyzed by our automated HVAC Analysis System, which generates a series of comprehensive Balancing Reports showing both test readings and the final conditions. For HVAC troubleshooting, readings are taken of current operating conditions, which are reported along with recommendations for correction action.
HVAC Tools
THB Company, Inc. uses the best and most accurate test equipment available today. Below is a partial listing of the instruments that we use for testing and balancing HVAC systems.
The Balometer provides accurate measurements of air inlet and outlet capacities. It has an electronic micromanometer that measures pressure differentials.
The Vane Anemometer is used to test sidewall register and exhaust inlet registers.
The Tachometers are used to measure rotation of fans, motors and pumps.
