What is Preventative Maintenance?

Sub-Zero Freezer Company recommends the general maintenance of your luxury appliance to ensure its proper operation for years to come.  This maintenance includes the cleaning of the condensing unit on your appliance every 3-6 months, but in most cases annually, as dirt, dust and pet hair can accumulate on the condenser coil preventing the airflow necessary for proper operation. Failure to clean the condensing unit may result in a loss of temperature, mechanical parts failure or general damage to the necessary systems of your luxury appliance.

As a courtesy to our customers, we are offering this maintenance service for $109.00. If you are in need of this maintenance, or would like to have your unit inspected by one of our experienced technicians, please call our customer service department toll free at (800) 492-2121 for help in setting up your service call.
