Sub-Zero Refrigerator Repair and Maintenance

As a Factory Certified Service and Premier Partner of Sub-Zero, we’ve provided unrivalled Sub-Zero refrigerator repair and maintenance to Greater Philadelphia for nearly 40 years. Our demanding performance standards ensure that we exceed expectations with every Sub-Zero service experience, which starts with these three foundational approaches to Sub-Zero refrigerator repair.

Expert Technicians
Our hand-picked, rigorously-screened, and highly-trained technicians are authorized to work on all Sub-Zero refrigerators and wine storage units, both under warranty and not. In fact, because they almost exclusively work on Sub-Zero appliances and receive ongoing training from the factory to stay up-to-date with the latest models, technology and specialized diagnostic tools, you can rest easy knowing that we can efficiently diagnose and repair any issue.

Genuine Parts
We only use genuine Sub-Zero parts on every service call. Since we also own and operate the Factory Certified Parts distributor for much of the Atlantic seaboard, our warehouse is always stocked with a comprehensive inventory of genuine Sub-Zero parts. Every one of our service trucks is also fully-stocked with Factory Certified Parts, often helping us solve problems on the first visit. These parts are covered by a comprehensive one-year replacement warranty.

White-Glove Service
We provide updates throughout the service process to provide peace-of-mind on the status of your appointment. Protective shoe covers and special drop cloths are utilized during every visit to protect your home’s many surfaces. And though our technicians are uniquely efficient at their job, they will always take the time to explain to you the problem, solution and cost involved in the repair or maintenance of your Sub-Zero unit.

The Sub-Zero Difference 

Sub-Zero is committed to creating the world’s finest refrigeration appliances. While other brands build appliances of all types, Sub-Zero has remained focused on refrigeration to refine and master their specialty.

Sub-Zero has the most energy-efficient refrigeration units — they last 56 percent longer than ordinary refrigerators. Even the larger models use less energy than a 100-watt light bulb. Sub-Zero refrigerators are made in the United States, and the cost of each appliance goes toward high-quality parts and manufacturing standards. With their state of the art design and luxury sensibilities, Sub-Zero appliances can be integrated into any room décor and withstand the test of time.

Those who already own a Sub-Zero refrigerator, freezer, ice machine, or wine storage unit know the many benefits of these revolutionary appliances. Sub-Zero refrigerator air purification and dual refrigeration keep air sealed between the refrigerator and freezer to keep food fresher and help it last longer. Your Sub-Zero refrigerator exceeds market expectations, but you can extend its efficiency and lifespan by providing regular maintenance and service. Be sure to call Appliance Repair Service for your annual Clean and Service, which includes a complimentary multi-point inspection.
