Where the gas main runs out and the tanks begin
Marcellus is where this county starts running short of gas main. Of its 2,711 occupied housing units, 1,971 heat with utility gas, 151 with fuel oil, 96 with bottled or LP gas, 370 with electricity and 28 with wood. The combined fuel oil and bottled gas share of 9.1 percent is the second highest in Onondaga County, and it introduces a failure a gas main cannot produce: the tank empties, or a delivery is missed, and the house goes cold with nothing broken in it. Check the gauge before you book anybody, because that check costs nothing and occasionally ends the whole matter.
What furnace repair involves
Why oil, propane and gas diverge at the burner
Once the supply is confirmed, the fault lists separate. An oil burner has a nozzle, a pump, a filter, an igniter assembly and a combustion chamber, and its characteristic failures are about atomization, fuel quality and soot. A propane appliance looks more like a natural gas one but runs at a different pressure with different orifices, so parts are not interchangeable and neither is the setup. A natural gas appliance in this town is the common case and its fault list is the familiar one. That is why naming the fuel first genuinely saves a visit rather than being a formality. It also matters that this town is old on both sides of the line: 38.4 percent of the village's 1,031 units and 31.8 percent of the town's 2,789 were built in 1939 or earlier, so heating was generally added to these houses rather than designed into them, which is where awkward pipe runs and undersized venting come from.
Read the gauge before you make the call
One Marcellus household in eleven heats from a tank on the property, 151 on oil and 96 on bottled gas. An empty tank produces exactly the same symptom as a dead appliance and costs nothing to rule out. It is the one check we would always rather you did than we did.
Oil and propane are not gas with a different label
Burner components, operating pressures and setup procedures differ. A contractor who works on oil burners regularly is a different call from one who works mostly on natural gas, and saying which you have gets the right one dispatched.
Heating was added to these houses, not designed in
38.4 percent of village units and 31.8 percent of town units predate 1940. Systems retrofitted into buildings that were never planned around them produce undersized venting and awkward pipe runs, and those are worth looking at during a repair.
9.1 percent on delivered fuel, the county's second highest
Of 2,711 occupied housing units in the town of Marcellus, the American Community Survey 2020-2024 five-year estimates report 1,971 heated with utility gas, 72.7 percent, 151 with fuel oil or kerosene, 5.6 percent, 96 with bottled, tank or LP gas, 3.5 percent, 370 with electricity, 13.6 percent, and 28 with wood. The combined fuel oil and bottled gas share of 9.1 percent is the second highest in Onondaga County. Of the occupied units, 2,126, 78.4 percent, are owner occupied.

Section M1801.3 of the Residential Code of New York State applies where an appliance is permanently disconnected from an existing chimney or vent, or connected to an existing chimney or vent during a new installation. M1801.3.1 requires the chimney or vent to be resized as necessary to control flue gas condensation in its interior and to provide the appliance or appliances served with the required draft, with resizing for oil-fired appliances vented to masonry chimneys done in accordance with NFPA 31. M1801.3.2 requires the flue gas passageway to be free of obstructions and combustible deposits, to be cleaned if previously used for a solid or liquid fuel-burning appliance or fireplace, and the flue liner or inner wall to comply. M1801.3.3 requires a cleanout opening in masonry chimneys and M1801.3.4 sets clearance to combustibles.

Oil or propane, and the heat stopped?
Read the tank gauge first. If there is fuel in it, send us the Marcellus address and we will get somebody who works on that burner.

Marcellus questions about oil, propane and gas furnaces
My Marcellus furnace runs on oil and keeps locking out. What causes that?
Start with fuel and work in. A tank that is low draws sediment and water from the bottom, which blocks the filter and the nozzle, and that alone produces repeated lockouts. Beyond that the usual suspects on an oil burner are a worn or wrong nozzle, a failing pump, a dirty or misaligned igniter electrode, a clogged filter, or a combustion chamber that needs cleaning. What is worth avoiding is repeated resetting: each attempt can put more unburned oil into the chamber and make the next start worse. Note how many times it has tried, check the gauge, and tell us both along with the address.
Can a contractor who works on natural gas service my propane furnace?
Sometimes, but it is worth asking rather than assuming. Propane and natural gas appliances look similar and share a lot of their architecture, but they operate at different pressures with different orifices, and conversion between them is a specific procedure rather than a settings change. In a town where 96 households are on bottled or LP gas and 1,971 are on a utility main, the default assumption a dispatcher makes will be natural gas unless you say otherwise. One word in the first line of your request prevents a wasted visit, so it is worth the keystrokes.
