A compressor overhaul usually involves an inspection and replacement of worn parts within your refrigeration compressor. We’ll assess items such as: pistons, piston liners, con rods and bearings. Any part where friction is applied during the continued operation of the compressor.

Knowing when to overhaul a unit is important, and there are certain signs that indicate a unit needs attention. Performing routine fluid checks, taking oil samples, and routinely checking for bearing vibration can unveil indicators that suggest an upcoming failure. Oil contamination with metal fragments usually indicates parts are wearing. It’s also important to take notice of airend temperature increases. If internal compressor temperatures go up, that’s a good indicator that the cooler may be failing.
