Had Brian come out to check on a opener that was not working too well anymore. He presented options to try and repair the gears or for a replacement. We opted for the new liftmaster with the DC motor and belt drive. He installed it that day and everything went smooth. The new garage door opener is amazing. Our old one rattled the entire house! The new liftmaster is smooth and quiet. Added on a wireless keypad and a mini keychain remote. This is the 3rd time we have used them. They have also replaced the springs, cable, rollers in the past. They don't seem to try and sell you things you don't need.
