Certified Refrigeration is a small family business with a deep expertise working with Sub-Zero refrigerators. Based in North Jersey, we specialize in efficiency as our small team is fully equipped to zip around the tri-state area and make fast accurate repairs. People love our service because of how well prepared we are. We really make it easy. When you call you speak to our office who will send us a quick little message to a professional. We will call you back shortly and discuss your Sub-Zero or Wolf’s issue. Over the phone we will figure out what kind of model you have, what the issue is and what we can do to help. If we think we know whats going on and you can repair it yourself, we always help you do so (lots of our reviews mention this). If not, we send out a technician to your home. Our preparation guarantees that when we arrive we are totally prepared to fix your refrigerator, freezer, oven etc.
