Copeland Expansion Valve Issue - AC-Renew

Climatemaster Heat Pumps

Re: Copeland Expansion Valve Issue / AC-Renew

Copeland put an additive in their scroll compressors that can cause the expansion valve to become sluggish or unresponsive.

AC-Renew can be added to the refrigerant system to counteract the additive.

Climatemaster is currently paying to install AC-Renew in units with the following Serial# ranges:

• R144 - R152
• S101 - S142
