Quick answer

Enter the unit's running power, how many hours a day its compressor runs and your electricity rate. The result is a daily and yearly running cost, useful for comparing a repair against a more efficient replacement.

Where to find the inputs

Running power of the unit (watts, from the nameplate or a meter) Hours per day the compressor actually runs (often 12 to 18 for a walk-in) Your electricity rate ($ per kWh, from your bill)

If a cooler, freezer or ice machine still is not right after the safe checks, a C-38 refrigeration technician can find the cause.
