Rooftop HVAC Unit: Repair or Replace?
Why Gotham Home Services
A commercial rooftop HVAC unit may be worth repairing when the main components remain serviceable, compatible parts are available, and the proposed work is reasonable for the equipment’s age and condition. Replacement deserves consideration after repeated failures, major compressor or heat-exchanger trouble, obsolete refrigerant, extensive corrosion, or performance that no longer meets the space. New York City projects also depend on roof access, lifting requirements, electrical service, controls, curb dimensions, and permitted work hours. No single age or percentage decides every case. Gotham Home Services inspects rooftop and packaged equipment for light-commercial properties, explains the findings, and provides a written repair or replacement quote before approved work begins.

Document model information, visible symptoms, when the issue began, and any building access rules. Stop operating equipment when there is smoke, sparking, a burning odor, repeated breaker trips, or a carbon-monoxide alarm; leave the area and contact emergency services or the utility when immediate danger is present.
