Is it significantly colder compared to when you installed the opener?

My Craftsman has a habit of balking when it gets really cold. I have
to increase the up and/or down force to get the door to travel it's
full distance. I should note that my opener is about 20 YO, however,
it has been doing it since the first cold winter.
