Replacement parts for Rheem air conditioners can be purchased from independent contractors who deal in Rheem products. They can also be purchased online from retailers such as Sears and All Parts Heating.
Rheem recommends using only parts that bear a special seal certifying their authenticity. Some dealers, such as All Parts Heating, recommend allowing professionals to service appliances. Others, such as Sears, offer "Expert Q&A" sections to provide answers to common questions. Some dealers provide customer service seven days a week, while others keep business hours Monday through Friday. Some online retailers ship from central warehouse locations, while others have multiple regional warehouses.
