On a repair call, a contractor working a boiler in Burlington County starts with the burner and the ignition system. Homes in Burlington County, NJ run heat about seven months a year, from October through April. That load falls almost entirely on those two components: the burner fires and extinguishes repeatedly across every cold month, and the ignition system strikes every time it does. By the time a boiler shows a fault, the igniter and the burner assembly have already absorbed seasons of that cycling. A contractor quotes the heat exchanger and controls after ruling those out first.

A boiler that has run in a house this old will show the contractor something specific once they open it: worn cast-iron sections, heat exchanger corrosion, or burner assemblies built to tolerances that current replacement parts fit only loosely. Half the homes in Burlington County, New Jersey were built in 1977 or earlier (2020-2024 ACS 5-year). That spread matters for repair work because parts availability follows the age of the design, and a fix that is straightforward on a newer unit can turn into a sourcing problem on a system like this. What the contractor finds inside determines whether the repair stays a repair.
The Parts of a Boiler a Contractor Checks First

The boiler itself sits in the basement or a utility room and is the heart of the system. It heats water that travels out to the rest of the house. When heat stops reaching certain rooms, or stops altogether, the boiler's burner, heat exchanger, or pressure relief valve is where a contractor starts looking.
From the boiler, supply pipes carry hot water to radiators or baseboard units in each room, then return lines bring cooled water back. The circulator pump moves water through that loop, and the expansion tank keeps system pressure stable. A pump that has seized or a waterlogged expansion tank will show up as uneven heat or pressure faults on the boiler's gauge.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific system.
