What you should know about your Old & New  Door Opener:

Performance requirements for your door opener depend on the weight of your door. A 1/3 horsepower opener may be adequate for single car doors and a 1/2 horsepower for double car doors. Heavier carriage doors usually require specially designed 3/4 horsepower openers. For most residential doors, it is perfectly fine to use 1/3 horsepower openers if you desire.

Opener codes are dictated by State and Federal guidelines (UL-325). Existing machines are checked first by the serial number and manufacturer name, then by proper installation and finally by condition. If a compliable machine does not work properly or a machine is not in compliance, our installing technician will tag the machine and notify you of the reason for the tag.

If you have an electric garage door opener on your door, itís not necessary to have a lock. Electric openers function as the lock, making it improbable that an intruder would be able to lift your door from the outside.
DASMA, the trade association for the garage door industry, discourages homeowners from attaching a lock when an opener has been installed, because too frequently, a child or other family member will accidentally lock the door. If someone then tries to open the door using the electric opener, the opener will pull against the lock causing the door to be damaged.
