The Capital District

The Sub-Zero Service Experience.

At Certified Refrigeration we provide Sub-Zero Refrigerator service for the Capital Region.  Counties we service are Albany, Columbia, Greene, Rensalear, Saratoga, Schenectady, Warren and Washington County. We exclusively service Sub-Zero refrigerators. Our technicians are trained on these machines, and have spent years learning how to properly diagnose, fix and restore Sub-Zero Refrigerators. We came into this trade through the necessity of specialization in the Sub-Zero Refrigeration Service industry. The Sub-Zero refrigerator is a household investment, and when it is serviced by an experienced technician using Factory Authorized Parts, its longevity is unrivaled. Some units that have been maintained by our company are going on their 35th year of service!

Service, Made Simple.

Over the years we have grown as a service business and learned some principles that make sense when dealing with the Sub-Zero refrigerator.These are some principles we live by, and if you choose us to fix your Sub-Zero, hopefully you will experience along with us.

  • Get to the call quickly, refrigeration is hard to live without.
  • Know the model number you are about to work on, stay prepared with a stocked truck.
  • Use only OEM parts on these machines, Sub-Zero sells them for a reason, do not source parts from Amazon, ebay, appliance part stores, etc…
  • Using charging cylinders for the accurate measurement to the ounce of refrigerant used on these units.
  • Keep your condensers clean. 
  • Be informative, the inner workings of these machines are an amazing thing, we like to inform all of our customers why and how we do the repairs we do.
  • Give good warranties, One Year or More, any Factory Authorized Part that is installed correctly should last way longer than a year.
