A boiler in Chaves County runs its burner and ignition system hard through most of the calendar year. Homes in Chaves County, NM run heat about seven months a year, from October through April. The heat exchanger cycles through that full run, and the ignition components fire at the start of every call for heat, making them the first place a contractor checks when the system is underperforming. Sediment buildup in the heat exchanger and worn igniter assemblies are common findings in boilers that have been carrying this kind of load without a service visit.

Piping that has been moving hot water through the same joints and fittings for a long time builds up scale and sediment in ways that shape what a boiler repair actually requires. Half the homes in Chaves County, New Mexico were built in 1972 or earlier (2020-2024 ACS 5-year). A contractor who opens a boiler in a house like that finds heat exchanger surfaces and circulator components that have been working against that buildup, and what they find determines whether the repair is a part swap or something that runs deeper into the distribution system. Visible symptoms at the boiler itself sometimes trace back to a loop that has never been flushed.
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 goes to first. It houses the burner, the heat exchanger, and the controls that keep water at the right temperature. When heat stops reaching the rooms, or water pressure drops, or the unit short-cycles, the problem usually starts here.
From the boiler, supply pipes carry hot water to radiators or radiant panels in each room, and return pipes bring cooled water back. The circulator pump, mounted on those pipes near the boiler, is what moves water through the loop. The expansion tank, also close to the boiler, absorbs pressure changes as water heats and cools.
The drawing shows a typical layout, and a licensed contractor will determine which components apply to your specific system.
