What a contractor has to work out before quoting a replacement is whether the unit in front of them has run a quiet life or a hard one. 11,578 severe weather events were recorded in Virginia between 2015 and 2024. At that rate, equipment across the state is asked to hold capacity and recover again on a schedule that wears components faster than calendar age alone predicts. A system installed a handful of years ago in a county that caught the brunt of that load can arrive at inspection in worse condition than an older one that ran easier years. Age on the nameplate and actual wear are two different numbers, and a contractor reads the second from the equipment itself.
A water heater replacement connects to whatever gas line, vent, and circuit were already there. Those were sized for whatever unit sat in that spot before, not necessarily for the one going in now. Half the homes in Virginia were built in 1984 or earlier, and half in 1984 or later (2020-2024 ACS 5-year). That split means a contractor cannot guess which kind of hookup is waiting in a given closet or utility room without opening it up and looking. A vent that is undersized for the new tank, a gas line sized for a smaller unit, a circuit that was never meant to carry the load. Any of these can be sitting behind a tank that looks ordinary from the front. Checking each one before the new unit goes in is the only way to know.

A water heater installed where it is exposed to wind, flooding or ice is at greater risk of a problem than one properly placed and secured. A tank set near a low point can take on water. A unit outdoors or in an unconditioned space can be damaged by a falling limb or a hard freeze. Have a contractor check where the water heater sits, how it is secured, and whether its venting and power connections are protected.
