Repair Or Replace? Contractors Help Building Owners Decide
"As a contractor, you can help owners make an informed decision by providing them with records of the original installation, periodic maintenance, and repairs, as well as the model and serial number and individual unit or site reference numbers," said Andy Fracica, brand manager for York International's Unitary Products Group.
According to Fracica, installation and operating instructions are also important, as is warranty information and factory or contractor-based service and maintenance agreements.
