I've been using Speedy for several years and for some reason I trusted them . A few years ago my sub zero refrigerator was not cold enough . Speedy came and said I needed a new coil . It cost $750 . Took the crooked repair man 15 min to install it . I just had the same problem and I called speedy again he says it's the coil again and smiled and says now it's $ 900 . I told him to get out of my house . Then I had a honest repair man come , the fridge was just low on freon he put more in and it's working perfectly . Also I saw the coil for sub zero on Amazon for $180 . Speedy probably gets them for less than that then charge you $900 and you don't even need one.
