Cost Of Installation 3240m System?
Under ideal conditions, what is the approximate cost to buy and have installed a LiftMaster 3240M for a roll up door which has previously had a Sears opener? The price on the Sears unit alone is less than $200 which includes TWO remotes AND a number pad. A tech just installed a 3240M with two remotes and NO number pad. The total bill was OVER EIGHT HUNDRED DOLLARS! The tech did a great job, but for three hours work, the labor cost OVER SIX HUNDRED DOLLARS!
