How To Produce A Reliable Test And Balance Report

How To Produce A Reliable Test And Balance Report

By Zelma Hurley


Testing and balancing is the final procedure considered for an HVAC system after it is being installed. When an engineer designs the HVAC system, he will surely follow a certain procedure. The indoor temperature will be determined as well as the humidity levels that will be needed to be maintained in the space. The outdoor design conditions will be determined based upon the location.

The maximum number of individuals will also be determined who will be occupying the space and the appliance and lighting loads anticipated. From this information of proper ventilation requirements, the amount of the outdoor air will be determined and will be brought into the space. This is just the beginning of the test and balance report Chicago that a contractor will produce.

After the installation process, the contractor can perform the test of the unit to identify the quantities that should be delivered and the right balance of the unit to make sure that the specified quantities are being delivered to the outlets. The test and balance procedure is a way to check the air quantities to be brought to the unit at the conditions required for the outlets.

It also provides certain details to be certain that the units handle the specified total quantities of air and to ensure that the unit is operating based in the specifications of the manufacturer. If the system used chilled or condenser water the test and balance process will also include measuring of water quantities that pass throughout the unit and the temperature of the entering and exiting water.

The importance of the process cannot be overemphasized. After all, this is a great way to conduct proper measurements to determine whether the system performs as specified and designed. These procedures are also used to take measurement needed for the whole process. Therefore, the need for a contractor that is unrelated to the process is obvious.

Actually, the tools and instruments are widely used to take precise measurements. They are also sensitive and expensive. In the HVAC industry, this process is very important and becomes a specialty performed by contractors who are members of the national groups. Once the work has been completed, the contractors will issue their report about the system.

If the contractor cannot get the systems to deliver the needed design air quantities. It often indicates a problem with either the design or installation of the systems. Usually, the report will show some discrepancies between the design air and measured quantities that will lead to maintenance issues. Basically, the testing and balancing report is a report card of the units performance.

Due to its importance, it is strongly recommended to hire a contractor directly by the retailer in Chicago IL rather than being hired by an HVAC subtractor or general contractor. Without asking the integrity of the contractors as a team, there is also a possibility that issues will be overlooked when the repair of issues will be the responsibility of the person who is paying you.

These reports can also determine if the issue may be results of a poor installed system or because of a poor design. Once you understand the importance of the procedure, the next thing to consider is to learn how to read the report.
