A boiler working through a Louisiana heating season cycles its burner and ignition system hard, and the wear lands on specific parts. Homes in Tangipahoa Parish, LA run heat about five months a year, from November through March. By March, the igniter, the flame sensor, and the heat exchanger have logged the kind of repeated thermal stress that shows up as cracked seals, fouled sensors, or an ignition sequence that hesitates before it lights. A contractor quoting a repair here checks those components first, because that is where the season's load concentrates.
Boilers in housing this old have usually been repaired before, and what a contractor finds once the unit is open reflects that history: replacement seals, non-original fittings, or components that were already substitutes for discontinued originals. Half the homes in Tangipahoa Parish, Louisiana were built in 1993 or earlier (2020-2024 ACS 5-year). That matters for repair work because a system running in a house that old draws on a parts supply that has had time to thin. A contractor may open the unit, identify the failed component, and then spend more time sourcing a compatible part than performing the repair itself.
The Parts of a Boiler a Contractor Checks First
The boiler itself sits in the basement or a utility room and is the piece a contractor goes to first. It heats water and circulates it through the system. The heat exchanger inside it is where problems most often start, so that is the first surface a contractor reads carefully.
The circulator pump moves hot water through the pipes to the radiators or baseboard units spread through the house. The expansion tank, usually mounted near the boiler, keeps pressure stable as the water heats and cools. The thermostat on a wall upstairs tells the whole system when to fire.
The drawing shows a typical layout, and a licensed contractor determines which parts and conditions apply to this particular home.

Severe Weather Events in Tangipahoa Parish
Weather puts real hours on boilers. Each storm cycle that swings temperatures or cuts power sends heating systems through the kind of stress that surfaces hidden faults, and that pattern is specific to this parish and the conditions it sees.
