Replacing a central heat pump compressor

I am having a heat pump scroll compressor replaced on a Ruud that is under 1 year old under warrenty. My question is other than replacing the compressor what else should be replaced or added? Does the refrigerant need to be replaced? Does the compressor relay need to be replaced (contacts may be burned)? Should they install a filter in the referigerant line? Any help would be appreciated

Well first its like what took it out??As to just what all should be done to it. But they should recover the freon pump it out not just blow it. Now like if you had a bad burn out they should try and clean all the lines and coils first then put the new compressor in. You want for sure a new liquid line drier and on the suction line for sure a 2-way heatpump filter drier. Then vacuum the whole system down real good and charged it. On the electric end just what is bad put new in.

The Repairman just said the compressor was bad and probably a factory defect and would be replacing the compressor. He did smell the freon from one of the ports. He is going to be replacing the compressor tomorrow and I wanted to be sure they do the job correctly, so based on the "factory defective compressor" They should put on a new dryer/filter and compressor. They usually don't recover all the system freon just the freon in the condenser unit, is that correct?

Most compressor failures are from mechanical problems. A severe burnout that spreads contaminants outside of the compressor is rare. The liquid line drier must always be replaced. The refrigerant can be recovered and reused by a competent technician.

The cause of any compressor failure may not be evident until a new compressor is installed and operating. This is a good reason not to replace compressors in out of warranty systems. The final cost may be way too much.

Manufacturer's defects are rare. The most common cause of compressor failures is low airflow (Dirty filters, dirty coil, incorrectly sized and poorly designed ductwork, etc.)

Some useful information on air conditioners and their care...is at http://www.eere.energy.gov/consumeri...s/aircond.html
