The tank in your garage may have been there longer than you have, since water heaters often come with the house. An owner or two before you probably put it in, and most people don't think about it at all after that. A water heater usually works without trouble for years until one morning there's no hot water.
A water heater usually gives you some warning before it fails. The water runs a little cooler or runs out a little faster, the pilot goes out more often, or rust or a damp spot shows up around the bottom where it's always been dry. Calling at that stage gives you time to weigh whether a repair makes sense at the tank's age, whether the household has outgrown it and whether replacing it now on your terms is the better plan.
When someone comes out, you get a clear assessment, not a scary one. If a small repair fixes it, that's what you'll hear. If the tank's near the end, you'll hear that too, with the reasons in plain English and the decision left with you.
