Chain Drive VS Screw Drive Garage Door Opener?
I installed a Stanley screw drive garage door opener about 9 years ago. I have a solid wood sectional double-car door that is quiet heavy and the opener just won't lift the door anymore. I had a repair man out today and he says i need a new opener. He says that companies will tell us to put in a screw drive but he says they are bad in the cold and he would only put it a chain drive. He also thought that I would be better off buying a good Sears chain drive and installing it myself. What do you think? My self installed opener only lasted 9 years. Are professional openers better than self installed openers? Should I go with a Chain or a Screw Drive?
