The equipment can be working perfectly and the building can still feel wrong. That is a balance problem, not a breakdown.
Testing, Adjusting and Balancing · Kitchen pressure correction · VAV recalibration · Written balance report
The short answer
A commercial HVAC system can be operating correctly and a building can still feel uncomfortable, one tenant space ten degrees colder than the one next to it, a lobby that never cools down, or a kitchen that will not maintain negative pressure against the dining room. This is rarely an equipment failure. It is almost always an air balance issue: ductwork, dampers, and diffusers delivering the wrong volume of air to the wrong locations relative to what the building’s load actually requires.
Headquartered in Sarasota and serving commercial clients throughout Collier County, Hillsborough County, Lee County, Manatee County, Pinellas County, Sarasota County, and surrounding areas, Putnam Mechanical provides professional Testing, Adjusting, and Balancing (TAB) services for commercial properties across Florida’s Gulf Coast. Our experts measure actual airflow and static pressure at each register and diffuser, compare the results against design specifications, and adjust dampers, VAV boxes, and duct configurations until every zone receives the air volume it was designed for. For buildings that have been renovated, re-tenanted, or expanded over the years without updating the original duct design, a current balance assessment is often the fastest way to resolve comfort complaints without replacing equipment.
Air balance work also plays a direct role in code compliance. Commercial kitchens require correct makeup air and negative pressure to control smoke, grease, and odor migration. Healthcare and laboratory spaces often have specific pressurization requirements between rooms. Getting the air balance wrong in these environments is not just uncomfortable, it can result in a compliance failure.

What we resolve
Based in Sarasota and serving Collier, Hillsborough, Lee, Manatee, Pinellas, Sarasota Counties and surrounding areas, Putnam Mechanical provides expert building balance services for commercial refrigeration and HVAC systems. Our team resolves building balance issues including:
New partition walls, a bigger kitchen hood, or added square footage can all unbalance a system that was correct when installed. Start here before replacing equipment.
What to know
A proper testing, adjusting, and balancing (TAB) visit starts with measurement, not guesswork. Putnam Mechanical’s Sarasota-based technicians use calibrated instruments to record airflow at each supply and return, document static pressure across the system, and identify where the as-built ductwork has diverged from the original design intent. From there, we adjust dampers and diffusers, recalibrate VAV controls where applicable, and re-test to confirm the corrections hold. For larger commercial properties throughout Collier, Hillsborough, Lee, Manatee, Pinellas, Sarasota Counties and surrounding areas, we provide a written balance report that documents before-and-after readings—useful both for your internal records and for satisfying inspectors or insurance requirements.
Most commercial properties do not think about air balance until something changes. A new tenant build-out adds partition walls that alter airflow paths. A kitchen hood is replaced with a larger unit that pulls more exhaust than the makeup air system was designed to handle. A property adds square footage without updating the original duct design. Any of these can disrupt a system that was correctly balanced when it was first installed. If comfort complaints started after a renovation, a new build-out, or an equipment change, an air balance assessment from Putnam Mechanical is usually the first step to take before assuming the HVAC or refrigeration equipment itself is the problem.
Balance work is scheduled. If a system has failed outright and a space is uninhabitable now, call for priority dispatch.

Building air balance (TAB — Testing, Adjusting, and Balancing) is the process of measuring and adjusting airflow throughout an HVAC system so every zone receives the volume of air it was designed for. Without it, some areas run too cold, others stay too warm, and equipment works harder than necessary to compensate.
If individual rooms are inconsistently hot or cold despite a properly functioning HVAC unit, if comfort complaints are isolated to specific zones, or if problems started after a renovation or build-out, air balance is a likely cause. A measurement-based assessment can confirm it before any equipment work is recommended.
Yes. Commercial kitchens depend on correct pressure relationships to control smoke and odor migration, and healthcare or lab spaces often have specific pressurization requirements between rooms. An out-of-balance system can put either at risk.
Yes. We document airflow and pressure readings before and after adjustments, which gives you a written record for your files or for an inspector or insurer if needed.
There's no fixed schedule, but it's worth reassessing any time a space is renovated, re-tenanted, or has equipment replaced, or any time comfort complaints appear that weren't there before.
