Refrigeration compressor brands we work on

Semi-hermetic piston and screw compressors for refrigeration and air conditioning systems, across ammonia and freon. These are the brands we service.

We repair, overhaul, inspect and commission all recognised compressor brands used in commercial refrigeration, industrial refrigeration and air-conditioning systems. These are the ones we see most often — if yours is not listed, send us the make, model and serial and we will tell you straight whether it is work we can take.

A full strip-down is what "overhaul" means here — every unit that comes off the bench has been opened, measured and rebuilt to spec, not swapped out and hoped for.

Manufacturer names are used to say which brands we service, not to claim dealership or endorsement. Badges without a logo file render as a plain wordmark.
