A used reach-in or prep table can save you 40–60% over new — but refrigeration is where a bad buy hurts most, because a failing compressor can cost more than the unit. Here's how to separate a workhorse from a money pit.
Start with the compressor and how it holds temperature
The compressor is the heart of the unit and the most expensive thing to replace. Ask when it last ran, and if you can, plug it in and let it pull down to temperature — a healthy reach-in reaches 34–38°F within 30–45 minutes and holds steady without short-cycling.
Listen for loud rattling or a compressor that kicks on and off every couple of minutes. That short-cycling usually points to a failing start component or low refrigerant, both of which mean service.
Gaskets, doors and seals are the cheap tells
Door gaskets are inexpensive to replace but tell you how the unit was treated. Cracked, torn or greasy gaskets mean the cooler has been working harder than it should — and often that the previous owner deferred maintenance elsewhere too.
Open and close every door. Hinges should be tight and doors should self-close and seal. A door that sags or won't seal bleeds cold air and runs up the compressor hours.
Match the unit to your kitchen, not just the price
Reach-ins, prep tables, glass-door merchandisers and undercounter coolers all solve different problems. A pizza prep table with a cracked cutting rail or a merchandiser with a failed anti-condensate heater can be worth fixing — or not — depending on the part cost.
Check the electrical requirements too: some units need a dedicated 208–240V circuit. Confirm your space can supply it before you buy.
Check before you buy
- Powers on and pulls down to 34–38°F within ~45 minutes
- Compressor runs steadily without short-cycling
- Door gaskets are intact and doors self-close and seal
- No standing water or heavy rust in the interior or drain pan
- Voltage/plug matches an available circuit in your space
- Ask for the age and any service history of the compressor
