Commercial HVAC repair
When a rooftop unit fails on a Florida afternoon, there’s usually little warning, one moment it’s cooling, the next it’s short-cycling, tripping breakers, or pushing warm air into a building full of customers or employees. Commercial HVAC repair has to happen quickly, but speed without an accurate diagnosis only leads to repeat breakdowns and more service calls.
Headquartered in Sarasota and serving businesses throughout Collier County, Hillsborough County, Lee County, Manatee County, Pinellas County, Sarasota County and the surrounding areas, Putnam Mechanical delivers expert commercial HVAC repair for rooftop units, package systems, split systems, and multi-zone equipment along Florida’s Gulf Coast. Our technicians identify the true point of failure, whether it’s a failing capacitor, a refrigerant leak, a control board fault, or a clogged condensate line, before recommending repairs, so you are not paying for parts or labor that won’t actually fix the issue. With a well-stocked warehouse of common commercial components, most repairs are completed in a single visit instead of waiting on special-order parts.
Because commercial HVAC problems rarely occur on a convenient schedule, our repair experts are supported by a 24/7 emergency dispatch line for businesses that can’t wait until the next business day.

Emergency calls with no cooling, electrical hazards or safety issues are dispatched through our 24/7 line and prioritised over routine scheduling. Routine repairs are typically scheduled same day or next business day.
Our method
Every service call begins with a structured diagnostic process. Our Sarasota-based commercial HVAC experts check refrigerant pressures, electrical readings, airflow, and control signals to identify the true cause of the failure instead of guessing from symptoms. This is especially important in commercial systems, where a single rooftop unit often includes more components such as economizers, multiple compressors, and staged controls that can fail independently. Without a methodical check of each subsystem, someone might replace a part, see the unit run briefly, and then face another breakdown when the underlying issue returns.
Not every failure calls for a full system replacement, and not every repair is a smart investment on an older unit. As a general guideline, equipment under about 10 years old with a contained, clearly identifiable failure is usually a strong candidate for repair. Equipment past 12 to 15 years of Florida runtime, especially with a history of repeat repairs or a refrigerant type that is being phased out, often makes more financial sense to replace. The decision typically comes down to repair cost compared with remaining useful life and the increasing risk of future failures. Putnam Mechanical will provide that comparison honestly so you can choose what is best for your facility, rather than steering you toward whichever option would be more profitable for us.
