Look for references ; Have any of your friends, family and colleagues faced problems with their garage doors? Why not ask them for contact details of the technicians they hired? If they received excellent service, then it is quite likely that you will, too.
However, if this doesn't happen, you shouldn't think that you need garage door repair, but you shouldn't force the opener either. In case you go on hitting the button, it is possible that you will end up with a burned out motor, stripped gears or broken coils. Instead, you will have to do the work. Use a blow drier or heat gun to melt the ice.
If the rollers or other parts seem stuck, you can try brushing on some kerosene to the parts. If they are rusty, use steel wool to take away the rust and lubricate as usual. If they are badly corroded they may need replacement. You also need to take a look at the opener. If it is operated by a drive screw or a chain, you may need to lubricate these parts as well.
De-icing products will also do the trick. If you are sure that you won't damage the door, you could also use a flat shovel to break the ice. The skilled (and lucky) people will manage to open the door and in this case make sure to clean all water and ice from the spot where the floor and the garage door meet. This way you can ensure that the garage door will open the next time you need it.
