The Hamlet on Main Avenue
Wynantskill sits in the northeast corner of the Town of North Greenbush. NY 66 is Pawling Avenue on the Troy side of the line and becomes Main Avenue here, and most homes are on the side streets off it. The 2020 census counted 4,050 people.
The name comes from the stream. Kill is an old Dutch word for creek, and Wynant was Wynant Gerritsen van der Poel, who held a share of a sawmill on the stream in the 1650s. A Dutch Reformed church started around 1794 and a post office opened in 1820. In the 1950s the town historian says Main Avenue was called gas station row, with seven service stations in under a mile.
Wynantskill Homes and Heating Fuel
Wynantskill is mostly single-family homes from the middle of the last century. For the Wynantskill census place, the median home was built in 1959, about 37 percent went up between 1950 and 1979, and about 83 percent are owner-occupied. About 78 percent heat mainly with gas.
Oil is more common than the hamlet average suggests. Along the Main Avenue core, about 10 percent of homes still burn fuel oil, and across all of ZIP 12198, which reaches into rural North Greenbush, about 24 percent do.
Systems We See Here
Houses from the 1950s and 1960s were typically built with either a forced-air furnace and ductwork or a hot water boiler and baseboard. Where the original ducts are still in the walls, that makes central air or a ducted heat pump a reasonable add in many Wynantskill homes, as long as the ducts can carry enough air.
For homes still on oil, the choices when the old system fails are another oil unit, a switch to gas where the street has it, or a cold-climate heat pump with the old system kept as backup. Along Main Avenue, the town's 2015 design guidelines ask that rooftop heating and cooling equipment be screened from view.

Wynantskill Questions
Do I need a permit to replace a furnace in Wynantskill?
The Town of North Greenbush building department lists furnaces and water heaters among the appliances that need a permit. Call the department at Town Hall to confirm for your project.
My 1950s house has its original ductwork. Will central air work?
Often, yes. Ducts from that era were sized for heat, so we check the duct sizes and the return air before adding a cooling coil and outdoor unit.
I heat with oil off Main Avenue. Is a heat pump worth a look?
It can be. Many oil homes add a cold-climate heat pump for most of the season and keep the oil system for the coldest nights. The house and its insulation decide how far a heat pump can carry it.
