- Oil Change
- Engine Tune-Up
- Spark Plug Replacement
- Tire RotationI just have to address this because I come from an automotive background. What is a "Tune Up" on a garage door? Where are the spark plugs, how do you change the points / set the dwell, adjust the timing? Do you need to check the compression every tune up? How about adjusting the valves? SORRY, just making fun of the guys who offer a "FREE GARAGE DOOR TUNE UP". This is like a free oil change on your car, or a free tire rotation. the only reason a shop does either of these things is to get you in so they can UPSELL you. SHOCKER, there are no free lunches.
