Boiler Installation in Brooklyn
The right boiler, sized and installed right. Serving homeowners throughout Brooklyn, from Park Slope to DUMBO.
Newer construction and converted co-ops along the waterfront and in neighborhoods like Williamsburg and DUMBO bring a different mix — tankless water heaters, PEX repiping, and combi boiler systems that require different diagnostic tools than a century-old steam system. When it comes to boiler installation, that context shapes how we approach every job in Brooklyn — from the tools we bring to the diagnostic steps we take first.
Across Brooklyn, Queens, the Bronx, Manhattan, Staten Island, and Long Island, we've installed boilers in everything from single mechanical-room brownstones to multi-unit buildings with shared systems, so we plan around your building's actual constraints rather than a generic installation checklist. In Brooklyn specifically, we regularly see clay or cast-iron sewer laterals affected by street tree roots and frozen exposed pipes in uninsulated cellar and garden-level units, both of which factor into how we diagnose and price boiler installation calls in the area.

Our Process
How It Works
Home heat-load assessment
We calculate the correct BTU output for your home's size, insulation, radiator layout, and hot water demand — not guessed from the old unit's rating.
System design
We select the boiler type (steam, hot-water, or combi), fuel source, and plan venting, piping runs, and control placement before any equipment arrives.
Site preparation
The mechanical room and access path are protected, and the old unit — if one exists — is safely disconnected and removed.
Professional installation
The new boiler is set, piped, and vented to current code, with permits and inspections handled as required for the scope of work.
Commissioning & safety testing
We run a full combustion analysis and pressure test to confirm the system is operating safely and efficiently before we leave.
Walkthrough & training
We walk you through thermostat operation, basic maintenance, and what to watch for during the system's first heating season.

FAQ
Frequently Asked Questions
Installation costs depend on the boiler type, whether a fuel conversion is involved, and what venting the building can support, so a published flat price would be misleading. You get a clear, itemized estimate after an on-site heat-load assessment — before any equipment is ordered.
Most residential replacements are completed in one to two days, depending on how much venting and piping has to change. An oil-to-gas conversion or a switch to a condensing unit needing new venting typically runs to the longer end of that range.
Sizing comes from a heat-load calculation — square footage, insulation, window and radiator count, and domestic hot water demand — not from matching the old unit's rating. That matters because a great many existing NYC boilers were oversized to begin with, and copying that number forward carries the original mistake into the new system.
Often, yes. A single failed component on a sound, correctly sized boiler is a repair, and age alone does not change that. Replacement earns its cost when repairs have become annual, when the heat exchanger or shell itself is compromised, or when the original unit was sized wrong — because no repair fixes a sizing problem.
Yes, we serve homeowners across Brooklyn, including Park Slope, Williamsburg, Bay Ridge, Bushwick, and every neighborhood in between.
