Performance Test and Balance was started in order to
provide the best quality Independent Testing and Balancing
services to their clients. We take pride in every project we are
awarded no matter how big or small.

With more than 60 years of combined experience in the
industry there is nothing we can’t handle. Projects we have
balanced include Hospitals, Labs, Schools, Manufacturing
Facilities, Office Building and Residential Buildings as well.
We have worked for every possible client, Construction
Manager, General Contractor, Mechanical Contractor, Control
Contractor, Building Owner, Building Manager or Engineer.
And our goal is the same with each, wanting to end each
project so each party is looking forward to working together on
next project.
