Recommissioning a system can help determine if a compressor replacement makes sense, or if the whole system should be replaced.

Refrigerant migration can be damaging to a compressor. The refrigerant migrating back to the compressor can possibly slug the component.

The compressor’s discharge temperature can tell the service technician what is going on inside a refrigeration or air conditioning system.

Replacing a compressor is typically a major investment, so having to return and repair the same issue, or an additional issue, should be avoided.

When it comes to servicing compressors, technicians often encounter three issues: flooding, migration, and slugging.

This article will discuss tips on troubleshooting single phase, residential compressors that won’t start.

There are times when the attempt to do something positive can result in something unexpected. The annual increase in the number of hard-start kits being added to air conditioners is a perfect example.

If a system has a defective compressor, finding a replacement is generally easy, but here are a few tips, just in case.

The weird thing about compressor problems is that — well, it’s usually not the compressor.

It’s probably something else. Can the technician on the job today figure out what that something else is? That could determine whether it’s a successful call and a happy customer or a visit that appears successful until the new compressor fails (after several additional costs and a lot of frustration).

To obtain the heat content (enthalpy), it would be necessary to know both the pressure and temperature at this point and then use a thermal dynamic superheat table for this specific refrigerant.
