Reliable Air Conditioning Refrigeration

Walk-in door gaskets typically last 2-4 years and should be inspected every 6 months. Signs of failing gaskets: visible tears or cracks, frost buildup near the door frame, condensation on the door frame, noticeably warmer temperatures near the door, or the door not staying closed. A failing gasket forces the compressor to work harder, increasing energy costs and reducing equipment life.

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.

High-temperature commercial dishwashers must reach 180°F (82°C) at the final rinse to achieve proper sanitization per NSF and health department standards. Low-temperature chemical sanitizing machines must maintain proper chemical concentrations (chlorine, iodine, or quaternary). If your high-temp machine isn't reaching 180°F, it's not properly sanitizing and may fail health inspection. Call a technician immediately.
