Gas-fired water heaters run their burner, thermocouple, and gas valve every time the tank calls for heat, which in a home that heats with gas is constant year-round demand rather than seasonal. Utility gas heats more occupied homes in Archuleta County, Colorado than any other fuel, at 40.3% (2020-2024 ACS 5-year). That share of the housing stock means contractors here work almost exclusively on gas appliances, so a repair call follows a predictable path: burner assembly first, then the thermocouple and pilot circuit, then the gas valve. A unit that has been cycling hard for years tends to show thermocouple drift or a fouled burner before the tank itself gives out.
Water heaters in houses from this era were built and installed around product lines that manufacturers have since discontinued or retooled. When a contractor opens a unit and identifies what it needs, the next question is whether that part still ships, and from where, and at what lead time. Half the homes in Archuleta County, Colorado were built in 1996 or earlier (2020-2024 ACS 5-year). Stock that old has had time to cycle through replacements, but the replacement units sitting in those mechanical rooms are not always recent either, and a repair on a mid-range water heater of uncertain age can stall on parts availability before it stalls on anything else.
The Parts of a Water Heater a Contractor Checks First
The tank is what most homeowners see, a large insulated cylinder that sits in a utility room, basement, or garage and holds a supply of heated water ready to use. Inside the tank, the burner assembly or heating elements do the actual heating, and the thermostat tells them when to run. When water arrives cold or in short supply, a contractor starts here.
The anode rod runs down through the tank and slows corrosion from the inside out. The pressure relief valve mounts on the tank's side or top and releases if pressure or temperature climbs past a safe point. Cold water enters through a dip tube that pushes it to the bottom, and hot water exits from a separate port at the top, feeding the supply lines that run to the rest of the house.

Archuleta County's climate puts real stress on water heaters, and that stress compounds when storms hit. A unit that runs hard through weather-driven demand swings is a unit more likely to need a contractor's attention.
