Frequently Asked Questions
Your Sub-Zero has two independent cooling systems. The fridge and freezer don’t share air. If your fridge gets warm while the freezer stays fine, the issue is strictly on the fridge side—usually a failing fridge compressor, bad evaporator fan, or a faulty thermistor.
At least once every 12 months. However, if you have dogs or cats at home, or if you live near dusty coastal construction, you should clean them every 6 months to keep your compressor from overheating.
Absolutely. We service older legacy units (500 and 600 Series), built-in 700 Series drawers, as well as the latest BI, IT, IC, and PRO series models.
Yes! If your fridge stops cooling completely or you’re dealing with an active water leak, contact us right away. We keep open slots for local emergency repairs.

We had an urgent issue with our dishwasher. Davis Appliance was able to make it day of. They came and were wonderful, quick and efficient to identify the issue and fix it. The dishwasher is working great. Super happy. We'll call again when needed (but hopefully not for awhile).Posted on Google![]()

We've relied on Davis for appliance repairs over the past several years, and he has consistently provided excellent service. He is professional, knowledgeable, responsive, and communicates clearly throughout the process. His prices are always fair and reasonable. Davis first helped us resolve a cooling issue with our Sub-Zero refrigerator. More recently, he repaired our LG dryer by replacing the heating element. Shortly after the repair, our dryer began making loud noises. Davis was quick to respond and came back to investigate. He discovered a separate issue that was completely unrelated to the original heating repair. As a courtesy, he replaced the drum belt at no additional charge. We truly appreciate his professionalism, honesty, fair pricing, excellent workmanship, and commitment to customer service. We highly recommend Davis and will continue to call him for our appliance repair needs!Posted on Google![]()

Davis did a fantastic job. He is the owner as well as that is the name of the company. He fixed a Viking oven that was not working and he did it very quickly and reasonably. I really appreciate good vendors like this. We all need to reward people who do good jobs like thisPosted on Google![]()

We contacted Davis Repair about our Thermador freezer approximately five months ago. At the time, he was professional and pleasant. I specifically asked whether replacing the recommended parts would actually resolve the problem or whether we would be better off purchasing a new refrigerator. He assured me that once the part and the freezer lock were replaced, the issue would be resolved. Based on that assurance, we followed his recommendations and spent approximately $2,500 on the repairs. Fast-forward, last week, the freezer was again not working properly. I contacted him because, naturally, we were frustrated after having spent that amount of money. Instead of acknowledging our frustration, his response was, "It's not like it broke down in 2 or 3 days, it took 5 months." He came out again last week and charged us another $658. Unfortunately, the freezer still did not work properly after the service. The check has already been cashed, and we have now decided to purchase a new refrigerator. What is most disappointing to me is not simply the money we spent, but the fact that I specifically asked five months ago whether we should repair the refrigerator or replace it. I relied on his professional recommendation, spent approximately $2,500 following that recommendation, and ultimately ended up needing a new refrigerator anyway. I have already communicated my concerns to him and left the decision regarding the most recent payment with him. In my view, when a customer spends thousands of dollars following a repair recommendation and the underlying problem ultimately remains unresolved, it is reasonable to expect the service provider to acknowledge the customer's frustration and stand behind the work. My experience was that the interaction was pleasant as long as everything was going according to his expectations, but when I raised concerns about the results of the repair, I felt my frustration was not handled professionally. I am sharing this experience so other customers can make an informed decision before spending a significant amount of money on repairs for a Thermador refrigerator or freezer and I wish instead of relying on his advice I researched the issue more to see that maybe repair was not the way to go.Posted on Google![]()
