Oil-to-Gas Conversion in Bronx
Off oil, onto gas, sized and vented properly. Serving homeowners throughout Bronx, from Riverdale to Mott Haven.
Riverdale's larger, often older single-family homes also bring a steady stream of full boiler replacement and repiping projects as original systems reach the end of their service life. When it comes to oil-to-gas conversion, that context shapes how we approach every job in Bronx — from the tools we bring to the diagnostic steps we take first.
A large share of Bronx heating work is building-scale rather than single-family — prewar apartment buildings along the Grand Concourse and in Fordham running central plants that serve dozens of units. Converting a central plant is a different project from converting a house: the load calculation is larger, the gas service requirement is heavier, and the work has to be staged around not leaving a full building without heat.
The second thing that goes wrong is sizing. A great many oil boilers in New York were oversized when they were installed, and the easiest mistake in a conversion is to read the old unit's rating and order the gas equivalent. That carries the original error forward for another twenty years. An oversized boiler short-cycles — it fires, satisfies the thermostat quickly, shuts down, and repeats — which wastes fuel, wears components faster, and heats unevenly. A conversion is the one moment when correcting that costs nothing extra, because you are specifying new equipment anyway. We do a heat-load calculation against the actual building: square footage, insulation, window and radiator count, and how the existing distribution is laid out. In Bronx specifically, we regularly see aging risers and branch piping in prewar buildings and sewer backups in older two-family homes with shared laterals, 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 Bronx
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
Soot, odour, or oil staining around the burner and the surrounding floor
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.

What Bronx Homeowners Say
“I had a leak in my living room ceiling and couldn't figure out where it was coming from. Keon and his employee showed up quickly after I reached out. They were professional, patient, and took the time to explain everything to me.”

“Keon was able to come the same day. He was very meticulous pinpointing the issue and tried to be as minimally invasive as possible.”

FAQ
Frequently Asked Questions
Gas line work and permit-required portions are performed through appropriately licensed partner professionals, coordinated as part of the overall project rather than left for you to arrange separately. We will tell you upfront which parts of your specific job fall into that category.
Yes. Multi-family and co-op conversions bring extra coordination — board approval, shared chimneys, access to a central mechanical room, and scheduling around tenants — but they are a normal part of what we do across the boroughs.
There is no useful flat figure, because a large share of the cost belongs to the utility rather than to us — bringing a gas service line to the house can dwarf the boiler itself on some blocks and be modest on others. The honest sequence is to get the utility's number first, then price the mechanical work against it. We will not quote a conversion before that answer exists.
You contact the gas utility for your address — National Grid or Con Edison depending where you are — and request a service availability determination. A gas main on your street does not guarantee you can be connected affordably, so get their answer, including cost and timeline, in writing before committing to anything else.
Yes, and it is a meaningful part of what we do here. It is a larger project than a house conversion — heavier gas service requirement, a bigger load calculation, and scheduling that has to avoid leaving the building without heat. It is planned around the heating season rather than dropped into the middle of it.
That depends on ownership. For a rental the owner or managing agent decides; for a co-op or condo the board generally has to approve anything touching gas service, venting or a shared chimney. We coordinate with whoever holds that authority rather than working around them.
Yes, we serve homeowners across Bronx, including Riverdale, Throggs Neck, Fordham, Pelham Bay, and every neighborhood in between.
