Air balancing vs water balancing is the basic split inside commercial TAB. Specifically, air balancing vs water balancing means two distinct trades — air-side covers diffusers, grilles, VAV boxes, and AHUs; water-side covers coils, pumps, and balancing valves. Both follow ASHRAE 111. Most commercial closeouts need both. The air balancing vs water balancing decision is
Testing adjusting and balancing (TAB) is the three-phase procedural process applied to commercial HVAC systems on every closeout. Testing adjusting and balancing under ASHRAE Standard 111 brings measured field performance into compliance with the engineer’s design intent and produces the stamped report owners need at substantial completion. The three phases of testing adjusting and balancing
Air balancing lowers commercial HVAC energy waste by getting the right CFM and GPM to the right zone. Specifically, air balancing lowers commercial fan-kW, chiller hours, and simultaneous heating-cooling waste. In our portfolio, a documented balance on a drifted building returns 8-15% in the first year — the kind of payback that makes air balancing
Skipping test and balance on a commercial closeout has predictable, expensive consequences. Owners and GCs who omit test and balance from scope typically discover the cost six to twelve months later, when energy bills run high, AHJs delay the CofO, and tenant complaints fill the work-order queue. What happens when test and balance is skipped
How do you know your commercial building needs air balancing? Seven signs point straight at it — hot and cold spots, doors that slam under HVAC operation, climbing utility bills, stale air complaints, humidity that won’t track setpoint, BAS overrides operations has been hiding, and tenant complaints that PM cycles never fully resolve. If two
Indoor air quality issues in commercial buildings most often trace back to airflow distribution — not to filter media, not to the AHU alone, and not to the OA damper in isolation. A documented air balance under ASHRAE 111 is the right first step on most indoor air quality complaints. How airflow distribution drives indoor
TAB services in Atlanta typically run as an independent third-party scope on commercial closeouts and on chronic-comfort retrofits in occupied buildings. Owners, mechanical contractors, and property managers engaging TAB services in Atlanta should expect a specific sequence and a specific deliverable. What TAB services in Atlanta cover First, the scope covers every diffuser, grille, VAV
