Signs your oven needs calibration: food is consistently undercooked or overcooked at standard settings, cooking times are significantly longer or shorter than expected, the displayed temperature doesn't match an independent thermometer reading. Oven calibration should be part of every service visit and can drift over time from component wear. A variance of more than 25°F warrants professional calibration.

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.

Consider replacement when: repair costs exceed 50% of replacement cost, the equipment is over 75% of its expected lifespan, parts are no longer available, the equipment frequently breaks down, or energy costs are significantly higher than modern alternatives. Repair when: the equipment is relatively new, the repair is straightforward, and the total repair cost is well below replacement value. A qualified technician can help evaluate your specific situation.
