A boiler in Gregg County has been running against real load. 105 severe weather events were recorded in Gregg County, Texas between 2015 and 2024. At that rate, severe weather is a standing condition for equipment here, and a contractor arriving at a repair call works through what that load has done to the heat exchanger, the pressure relief valve, and the flue connections before anything else. Those are the components that carry the strain when conditions outside are bad, and in this area they show it. Age and installation still matter, but the weather record means a contractor checks stress-related failure first.
Boilers in houses that have been through one or more equipment cycles carry parts tied to a specific manufacturer generation, and that generation may no longer be in production. Half the homes in Gregg County, Texas were built in 1980 or earlier (2020-2024 ACS 5-year). Stock that old has had time to accumulate layered service histories, which means the unit a contractor opens is almost never the one the house was built with. What that contractor finds when the system is open determines whether the repair is a parts order or a decision about replacement, and the answer comes from the serial plate and the heat exchanger, not from the age stamped on the permit.
The Parts of a Boiler a Contractor Checks First
The boiler itself sits in a mechanical room, basement, or utility closet and is the piece a contractor heads to first. It heats water and pushes it through the system. When it fails, symptoms range from no heat at all to uneven temperatures across rooms. The burner, heat exchanger, and pressure vessel are all inside this cabinet and each can be the source of the problem.
Radiators or hydronic baseboards sit in the living spaces and release heat into each room. The circulator pump, aquastat, and expansion tank live near the boiler and keep water moving at the right pressure and temperature. A failed pump, a waterlogged expansion tank, or a faulty aquastat can each produce symptoms that look similar from the outside.
The drawing shows a general layout of these components, and a licensed contractor determines which parts apply and what condition they are in for this specific house.

Severe Weather Events in Gregg County
Boilers work harder and wear faster when outside conditions swing hard, and Gregg County puts real stress on heating equipment. That stress is local, which is why repair needs here are not the same as repair needs somewhere else.
