Oil-to-Gas Conversion in Hicksville, NY
A lot of Hicksville homes still run on oil. Tank age, delivery hassle, and rising fuel costs are the three reasons homeowners finally make the switch to gas.

What it involvesWhat it costsFAQ
Once National Grid has a gas line running down your street, the conversion is usually more straightforward (and cheaper) than most people expect.
What the Conversion Actually Involves
Every conversion job has the same core pieces, even though the details differ by house:
Oil tank decommissioning or removal
Above-ground tanks are straightforward; buried tanks need a DEC-registered contractor and sometimes soil testing.
Gas line coordination with National Grid
Getting the meter set and the line run to your mechanical room.
New equipment install
A gas furnace or boiler sized to your home with a real Manual J calculation, not a guess.
Venting changes
Gas appliances vent differently than oil, so this is rarely a drop-in swap.
What It Costs
Pricing depends on tank type, gas line distance, and the equipment you choose. We’ll give you an exact number after a walkthrough, not a phone guess. National Grid runs rebate programs for qualifying high-efficiency gas equipment, and PSEG Long Island offers rebates on qualifying heat pumps – we’ll help you check what you qualify for before you commit to anything.
Common Questions About Oil-to-Gas Conversion
Is my oil tank required to be removed, or can it stay?
An above-ground tank you’re no longer using should be decommissioned properly rather than left in place – abandoned tanks can complicate a future home sale. A buried tank has stricter rules and may need testing before removal.
How long does the conversion take?
Most residential conversions take one to two days for the mechanical work itself, once the gas utility has completed the meter set – which is scheduled through National Grid and can be the longer lead time in the process.
Will I need to upgrade my zone controls too?
Sometimes. If your home has an older multi-zone baseboard setup on a Taco relay panel, we’ll check whether it’s compatible with the new boiler or furnace before we finalize the quote – it’s a common add-on we flag upfront, not a surprise afterward.
