Standard garage doors on today's market use a torsion spring system that counterbalances the weight of the physical door. When spring strength meets equilibrium with door weight, the industry calls the door "balanced." There are numerous factors that go into the equation that determines strength of torsion springs. Such as wire gauge, inside diameter, and spring length. If a garage door doesn't have the proper spring, it will feel too heavy to lift. Or worse, the door will fly open. Replacing torsion springs can be very dangerous and it's always recommended to hire trained professionals who both know the correct springs to use in every situation, and also know how to handle the job safely.
