Ever seen what happens when a commercial freezer coil isn’t cleaned for months? 😬 That thick “blanket” isn’t frost it’s grease, dust, and kitchen debris baking onto the coil like concrete. When coils can’t breathe, the whole system starts to suffer: ⚠️ Compressor overheats – it works twice as hard and eventually burns out. ⚠️ Fan motors seize – bearings dry up from constant heat. ⚠️ Thermostats misread – the unit never shuts off, wasting energy. ⚠️ Cooling drops – food starts to thaw or spoil.
