Quality Installation Specialists

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.

A comprehensive PM program should include: scheduled inspections at manufacturer-recommended intervals, cleaning of condenser coils and filters, calibration of temperature controls, inspection and testing of safety systems, lubrication of moving parts, replacement of wear items (gaskets, filters, belts), refrigerant level checks, combustion analysis for gas equipment, and detailed documentation for each visit. Avoid programs that are just a visual inspection without hands-on service.

Signs of a refrigerant leak: unit runs but doesn't reach temperature, ice buildup on evaporator coil, hissing or bubbling sounds from refrigerant lines, oily residue near connections or fittings, and higher than normal electricity consumption. Only EPA-certified technicians can legally handle refrigerant. If you suspect a leak, call a technician promptly — operating a refrigerator with low refrigerant damages the compressor.
