3.2 percent prewar in the county's largest housing stock
The American Community Survey 2020-2024 five-year estimates put the median year structure built in the town of Clay at 1978, plus or minus 1 year. Of 26,282 housing units, the largest count of any municipality in the county, only 831 were built in 1939 or earlier, 3.2 percent, 14,459 before 1980, 55.0 percent, and 4,053, 15.4 percent, in 2000 or later. Of 25,725 occupied units, 17,654 are heated with utility gas, 68.6 percent, 6,334 with electricity, 24.6 percent, and 832 with bottled, tank or LP gas, 3.2 percent. 18,316 units, 71.2 percent, are owner occupied.

The Energy Information Administration's 2020 Residential Energy Consumption Survey reports 16.04 million homes in the Middle Atlantic census division, which is New York, New Jersey and Pennsylvania. Of those, 8.24 million use a central warm-air furnace as their main heating equipment and 4.48 million use a steam or hot water system, which is 27.9 percent. Nationally the survey reports 9.29 million of 123.53 million homes on steam or hot water, which is 7.5 percent. Heat pumps are the main heating equipment in 0.68 million Middle Atlantic homes, 4.2 percent, against 16.13 million nationally, 13.1 percent.

What being the exception costs you on a hydronic call
Clay holds the largest housing stock in Onondaga County at 26,282 units and one of the smallest prewar shares: 831 units built in 1939 or earlier, 3.2 percent, against 4,053 built in 2000 or later. Practically every no-heat call in this town is a ducted, forced-air call, which is good news for the town and awkward news for you if your heat arrives off a radiator. Regionally hydronic heat is far from unusual, 27.9 percent of homes across New York, New Jersey and Pennsylvania run steam or hot water against 7.5 percent nationally, but that share is concentrated in the old villages rather than out here. The risk on a Clay hydronic call is simply the wrong trade arriving.
Make the system obvious before anybody is dispatched
Three sentences in the request do the work. First, how the heat arrives: radiators, baseboard or floor, which rules out every furnace checklist in one line. Second, how much of the house is affected, because one cold emitter is a valve, a vent or trapped air while a whole cold house is the circulator, the water level, the expansion tank or the boiler's controls. Third, what the pressure gauge reads, if there is one, because a system you have topped up more than once this season is losing water and that is the actual fault rather than whichever part gave up first. None of that requires any tools. All of it changes who turns up, which in a town where radiators are the exception is the single most useful thing you can influence.
Ask whether they work on hydronic systems regularly
It is a reasonable question rather than a rude one in a town that is 3.2 percent prewar. A contractor who sees boilers every week carries different parts and reaches the answer faster than one who mostly sees furnaces.
Repeated topping up is the fault, not maintenance
A closed hydronic system should hold its water. If you are adding some every few weeks, finding the loss matters more than replacing the component that failed because of it.
Nothing on a furnace checklist applies to you
No filter, no blower, no ducts, no vents to open. Advice written for the 96.8 percent of Clay housing built after 1940 will send you looking for parts your system does not have.
Radiators in a town of ducted houses?
Say so in the first line. Send the Clay address and describe how the heat arrives and we will get the right trade to it.

Clay questions about radiator and baseboard heat
How do I make sure the right kind of contractor comes to a Clay boiler call?
Say what the system is in the first line of the request and be specific about how the heat arrives: radiators, fin tube baseboard, or pipes in the floor. Then say whether it is one room or all of them, and whether the boiler is firing. Those three details are what a dispatcher routes on, and in a town where only 831 of 26,282 units predate 1940 they matter more here than they would in an older village. Send us that along with the address and we will arrange somebody who works on hydronic systems rather than the next available van.
The boiler runs constantly but the house never warms up. What is that?
Almost always circulation rather than combustion, which is why burner work will not touch it. The heat is being made and it is not reaching the rooms. The usual suspects are a circulator that has failed or lost its coupling, zone valves stuck closed, air trapped in the system after a top-up or a repair, or a system that has lost enough water that it is moving very little. On steam, a similar picture comes from failed vents or wet returns. Tell us whether the pipes leaving the boiler get hot and how far along they stay hot, because that single observation narrows it enormously.
