Alpha TAB is a fully independent, NEBB certified Testing, Adjusting, and Balancing contractor. Our team has been providing TAB services to the DMV — Maryland, Virginia, and Washington, DC — for more than 20 years.

About UsTAB is an acronym for Testing, Adjusting, and Balancing.
Testing, adjusting, and balancing are essential procedures to ensure the proper performance of building HVAC systems and indoor air quality. A balanced HVAC system helps reduce utility expenses, creates proper ventilation for better health and comfort, and extends equipment life leading to reduced maintenance costs.
Studies show that proper testing, adjusting, and balancing, along with commissioning, can result in energy savings of 15 to 30 percent. Certified TAB reports also satisfy the specification, code, and municipality requirements most commercial projects carry.
