Compressor Size Calculations and Charts

This chart shows the recommended compressor HP for commonly found domestic and commercial fridges and freezers.

Please check the chart below before replacing any compressor.

NEVER not rely on the compressor HP found in a fridge you intend on swapping out. There is a good chance the previous technician may have got it wrong and installed the wrong size.
