Alpha TAB is the premier independent testing, adjusting, and balancing contractor for Maryland, Virginia, and Washington, DC. We measure your building's air and water systems against the design — and hand your engineers a certified, color-coded report the next day.
TAB is the science of measuring and fine-tuning a building's HVAC air and water systems so every space receives exactly the airflow and water flow the design calls for. A properly balanced building runs quieter, costs less to operate, and keeps occupants comfortable.
Seventeen services, one standard: calibrated instruments, certified procedures, and documentation your engineers can trust. The six below are where most projects start.

Every diffuser, grille, and valve is identified on the drawing and tied to its measured reading — so your mechanical contractor and engineer know exactly what was tested, what passed, and what needs attention.
Alpha TAB holds no affiliation with any HVAC installation or service contractor. We don't sell equipment, and we don't profit from repairs — our findings are never influenced by anything but the measurements.
"When we certify a system, the numbers speak for themselves."
No project is too small or too complex. We bring the same calibrated instrumentation and certified procedures to a single-suite fit-out as we do to a full hospital tower.
Great balancing starts with great people. Alpha TAB is always looking for motivated technicians who take pride in precise, honest work — experience in HVAC or mechanical trades is a plus, but we'll train the right person.
