overhead garage door company question
We bought a home that has two OHGDC openers installed---LEGACY models. Are these good models and is this a good brand? We never had a garage before so I have no idea what I am looking at. Both work. My side is a little loud and makes a bit of a clunky noise. My wife's side is quiet and smooth yet I see the chain is not tight up against the rail that runs from the opener to the far wall where the door is. It actually hangs down. I have tried to find online manuals to educate myself as to what is right and wrong and have found nothing. Ideas?
