What to Watch for This Winter in Naugatuck
- A 38-inch frost depth means exposed hydronic loops in Naugatuck can freeze within hours of a no-heat failure when January lows hit 20°F.
- With 55% of Naugatuck homes on natural gas from Eversource Gas, igniter and flame-sensor faults are the top cold-snap failures — a boiler that fires for three seconds and locks out needs a sensor check, not a reset.
- Homes built before 1960 make up 50% of Naugatuck — check the low-water cutoff and Pressuretrol before the first freeze, not after the radiators go cold.
- If your home drops below 55°F, call (833) 873-0668 — average dispatch to Naugatuck is about 40 minutes via I-84.

Historic Homes in Naugatuck
Historic steam & cast-iron systems — 50% of homes in Naugatuck 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.
