Signs of compressor problems: unit not reaching temperature despite running constantly, compressor making loud knocking or grinding sounds, compressor starting and stopping rapidly (short cycling), compressor not starting at all, or high pressure shutdowns. Compressor failure is typically the most expensive refrigeration repair. Early diagnosis can sometimes allow for less costly repairs — don't wait if you hear unusual compressor noises.

Walk-in door gaskets typically last 2-4 years and should be inspected every 6 months. Signs of failing gaskets: visible tears or cracks, frost buildup near the door frame, condensation on the door frame, noticeably warmer temperatures near the door, or the door not staying closed. A failing gasket forces the compressor to work harder, increasing energy costs and reducing equipment life.

Commercial oven repair costs range from $200 to $2,000+ depending on the issue.

Diagnostic fees of $100-$200 are typically applied to the repair total.
