Summer in Freeport
- Failed AC capacitors — the #1 summer call. We carry every common size on the truck.

- Frozen condensate lines on high-efficiency furnaces during deep cold snaps.

Boiler repair in Freeport, NY — steam & hot water experts
A lot of Freeport homes still run on 40–60 year old cast-iron boilers. North Freeport has hot-water systems in the ranches; South Freeport has steam boilers in the older colonials near the Nautical Mile. We service both and stock parts for the six brands that cover this village.
No heat / boiler won't fire
Aquastat, low-water cutoff, gas valve, thermocouple, ignitor — all diagnosed in one visit. $99 diagnostic waived with repair.
Steam boiler service
Water-line skim, low-water cutoff flush, pigtail cleaning, and near-boiler piping inspection. Steam boilers that get annual service run 40+ years.
Leaking or flooded boiler
Freeport's high water table + Sandy-era mechanicals still in some basements = corrosion at the bottom of cast-iron sections. We diagnose and quote replacement honestly.
Boiler replacement
High-efficiency gas boiler installed $6,900–$12,500 depending on size and venting. National Grid rebates available.
