Historic Homes in Bethlehem
Historic steam & cast-iron systems — 62% of homes in Bethlehem predate 1960, and many still run one-pipe or two-pipe steam. That means Hartford Loop piping, McDonnell & Miller low-water cutoffs (LWCO), Honeywell Pressuretrols, and main line air vents are not museum pieces here — they are the parts that fail. Our techs skim boilers, check the Hartford Loop, clean pigtail siphons, and test LWCOs before recommending any replacement, because a steam system that is piped wrong will bang and surge no matter how new the boiler is.
