Oil-to-Gas Conversion in Manhattan
Off oil, onto gas, sized and vented properly. Serving homeowners throughout Manhattan, from Upper West Side to Hell's Kitchen.
We're experienced working within co-op and condo building rules, including required building notifications, freight elevator windows, and coordinating with management for any work affecting shared risers or stacks. When it comes to oil-to-gas conversion, that context shapes how we approach every job in Manhattan — from the tools we bring to the diagnostic steps we take first.
Most Manhattan residential heat runs through central steam plants in prewar co-ops and condos on the Upper West and Upper East Sides, so conversion here is usually a building decision rather than an apartment one. The constraints that dominate are access to a central mechanical room, shared chimney arrangements, and board approval — and the logistics of getting equipment into a building that was not designed with that in mind.
The first question is not which boiler you want — it is whether gas is available at your address at all, and on what terms. A gas main running down your street does not automatically mean a service line runs to your house, and the utility (National Grid or Con Edison, depending where you are) controls that part of the job, its cost, and its timeline. Some blocks are straightforward. Others require a street opening, and the utility's queue is the utility's queue. We tell people to confirm availability and get the utility's answer in writing before spending money on anything else, because every other decision in a conversion depends on it. In Manhattan specifically, we regularly see townhouse boilers original to early-1900s construction and building management coordination for shared-stack repairs, both of which factor into how we diagnose and price oil-to-gas conversion calls in the area.
For the full picture on this work — common causes, repair versus replacement, and what actually drives the cost — read our complete guide to oil-to-gas conversion.
Warning Signs
Signs You Need Oil-to-Gas Conversion in Manhattan
The existing oil boiler is at or past its service life and repairs are recurring
Gas is already serving the block and neighbouring houses have converted
You are replacing the boiler anyway, which is the cheapest moment to change fuel
An aging buried or basement oil tank you would rather not replace
Our Process
How It Works
Confirm gas availability first
Before anything else, we help you establish whether the utility can serve your address, what they will charge, and how long their side will take — in writing. Every other step depends on this answer.
Heat-load calculation
We size the new boiler to the building, not to the old unit's rating. A conversion is the one chance to correct an oversizing mistake without paying extra for the privilege.
Survey the gas piping and electrical
Interior gas piping has to carry the new load, and existing runs sized for a cooktop will not. We check what can be reused and what has to be upsized before equipment is selected.
Decide the venting approach
Chimney liner or sidewall direct vent, decided against the equipment and the building — including where exhaust terminates on an attached or row property.
Plan the oil tank decommissioning
Removal or abandonment in place, scheduled as part of the project rather than left as an afterthought, with the condition of a buried tank assessed before the work is priced.
Permits and licensed work
Gas line work and permit-required portions are coordinated through our licensed partner network, with filings and inspections handled as the scope requires — see our Licensing & Compliance page.
Installation, commissioning, and handover
The new system is installed, combustion-tested, and run through a full heat cycle under real conditions. We then walk you through the controls and what the system actually needs from you.

FAQ
Frequently Asked Questions
It has to be properly decommissioned — emptied, cleaned, and then either removed or abandoned in place to the applicable requirements, with the accompanying documentation. A buried tank carries the extra question of whether it has already leaked, which is a larger problem than the conversion and one worth establishing before the job is priced rather than during it.
Often not yet. Conversion has a payback period, and if the existing boiler is mid-life, correctly sized, and heating evenly, the economics usually argue for waiting. The moment conversion makes most sense is when you are replacing the boiler anyway — then the fuel decision costs you nothing extra to make.
Our portion is typically a small number of days once equipment is on site. The schedule is usually set by the utility's side — service line installation and meter setting — which can run weeks and is not something we control. Plan the project around their timeline, not ours, and start well ahead of heating season.
Usually, though how much depends on fuel prices and on what you are replacing. A meaningful part of the saving often comes from correct sizing rather than from the fuel switch itself — an oversized boiler short-cycles and wastes fuel whatever it burns, so a conversion that also fixes a sizing error tends to outperform one that simply swaps fuel.
Generally no, because in most prewar co-ops and condos the heat comes from a central building plant rather than a unit boiler. Conversion is a building-level project decided by the board and managing agent. If your apartment does have its own heating unit, that is a different conversation and worth a look.
Rarely the mechanical work. It is board approval, access and staging for getting equipment into the building, shared chimney and venting arrangements, and the utility's own timeline. Those are the items worth starting early.
Yes, we serve homeowners across Manhattan, including Upper West Side, Upper East Side, West Village, Harlem, and every neighborhood in between.
