A system that runs all day without ever cooling the building is often losing the air before it arrives.
Leak location and sealing · Damaged and disconnected runs · Insulation repair · Partial and full replacement
The short answer
Ductwork often goes unnoticed until there is a visible problem, yet leaking or damaged ducts are one of the most common reasons a commercial HVAC system runs constantly without ever fully cooling the building. Air that should be reaching a sales floor, kitchen, or office space can instead escape into a ceiling cavity, attic, or mechanical room, driving up energy costs while failing to deliver comfort where it is needed.
Based in Sarasota and serving businesses throughout Collier County, Hillsborough County, Lee County, Manatee County, Pinellas County, Sarasota County and surrounding areas, Putnam Mechanical inspects, repairs, and seals commercial ductwork for a wide range of facilities. Our refrigeration and HVAC experts locate leaks at duct joints, damaged sections, and disconnected runs, then repair or reseal them to restore the airflow your system was originally designed to provide. When ductwork is deteriorated beyond practical repair, which is common in older commercial buildings with decades of wear, we install replacement runs that are properly sized for current building use rather than simply duplicating the existing layout.

What we fix
One zone far warmer than the next, or a system that never satisfies the thermostat, often traces back to ductwork rather than the equipment.
What to know
For commercial facilities in Sarasota and throughout Collier, Hillsborough, Lee, Manatee, Pinellas, Sarasota Counties and surrounding areas, a duct system losing even 15 to 20% of conditioned air to leaks, which is common in older commercial ductwork, forces the HVAC equipment to run longer and harder to maintain the same comfort level. This shows up directly as higher utility costs. It also means the equipment is operating under more strain than its design load allows, which can shorten compressor and motor life. Sealing and repairing ductwork with the commercial HVAC experts at Putnam Mechanical, headquartered in Sarasota and serving all of these counties, is often one of the most cost-effective improvements for an older commercial building because it reduces load on equipment that does not need to be replaced just to correct an airflow problem.
For many commercial properties in Sarasota and across Collier, Hillsborough, Lee, Manatee, Pinellas, Sarasota Counties and surrounding areas, sealing and patching is usually the right choice for isolated leaks, loose joints, or sections with manageable damage. Full or partial duct replacement makes more sense when insulation has failed throughout the system, when ductwork was undersized or poorly routed during the original installation, or when a renovation has changed the building layout enough that the existing duct paths no longer match current room use. Putnam Mechanical, your Sarasota-based commercial refrigeration and HVAC experts, carefully evaluates actual duct condition and airflow performance before recommending the repair or replacement approach that makes the most sense for your building.
