A compliant hood cleaning includes: complete degreasing of the hood canopy, all grease filters, the entire ductwork system from hood to exhaust fan discharge, and the exhaust fan and housing. Areas that cannot be thoroughly cleaned must be documented. Cleaning must be performed by a qualified company and documented with service report and before/after photos. The technician should leave a dated sticker on the equipment and provide a compliance certificate.

Most commercial kitchen equipment installations require permits: gas appliance permits for any gas connection work, electrical permits for new circuits or panel changes, plumbing permits for water and drain connections, and health department approval for new food service operations or major renovations. Requirements vary by jurisdiction — your installer should know local requirements. Operating without required permits can result in fines and forced closure during inspections.

Signs of compressor problems: unit not reaching temperature despite running constantly, compressor making loud knocking or grinding sounds, compressor starting and stopping rapidly (short cycling), compressor not starting at all, or high pressure shutdowns. Compressor failure is typically the most expensive refrigeration repair. Early diagnosis can sometimes allow for less costly repairs — don't wait if you hear unusual compressor noises.
