Boiler configurations vary by neighborhood age and distribution type. North Shore and pre-war South Shore homes may use cast-iron radiators or steam, while post-war homes often use hydronic baseboard loops. Steam replacement sizing should account for connected radiation, while condensing-boiler performance depends on the design water temperatures, radiation, controls, venting, condensate, and piping. Compare written proposals that identify the exact equipment, sizing basis, near-boiler piping, venting, electrical work, domestic-hot-water assumptions, permits, exclusions, and commissioning scope.

Frequently Asked Questions
Do you service steam boilers in Nassau County?
Share the boiler, fuel, one-pipe or two-pipe distribution, symptoms, and requested scope so steam capability can be confirmed before scheduling. Skimming, main venting, controls, piping, and water quality may all affect the diagnosis.
Should I replace my cast-iron boiler with a condensing unit?
The answer depends on the distribution system, design water temperatures, heat loss, radiation, chimney or venting, controls, condensate, domestic-hot-water needs, and installed cost. Review modeled performance and the written scope for the specific home.
Do I need a permit to replace a boiler in Nassau County?
Requirements vary by town, fuel, venting, electrical work, and project scope. The written proposal should identify who determines, files, pays for, schedules, and closes each required permit or inspection.
What boiler brands do you install?
For condensing: Triangle Tube Prestige and Weil-McLain WM97+. For cast-iron: Peerless and Burnham. For combi: Navien NCB series. Steam replacements are typically Peerless or Burnham sized to your EDR.
Can you evaluate an oil-to-gas boiler conversion?
A conversion assessment should identify fuel availability, utility responsibilities, tank work, gas piping, venting, electrical work, equipment, permits, inspections, exclusions, and which party owns each step. Capability and scope are confirmed for the specific property.
