Sizing a furnace for a Hudson County home starts with how long the burner actually runs. Homes in Hudson County, NJ run heat about seven months a year, from October through April. A heat exchanger and ignition system cycling through that kind of season accumulate wear that a contractor quoting off a generic table will not see coming. The installer has to build in capacity that holds up through months of repeated on-off cycling, not just through a cold week or two. An undersized unit runs longer burner cycles to chase the setpoint, and those cycles are where ignition components and heat exchangers fail.

Ductwork in stock this old was sized around equipment that has since been replaced, sometimes more than once, and each replacement shifted the load the ducts were designed to carry. Half the homes in Hudson County, New Jersey were built in 1966 or earlier (2020-2024 ACS 5-year). A contractor installing a furnace here has to evaluate what the existing duct runs can actually handle before the new unit is chosen, because a box that does not match what the house will move will underperform regardless of its rating. The electrical side is a secondary check, but it is the ductwork that determines how the job is scoped and priced.
What Gets Installed With a New Furnace

The furnace itself sits in a mechanical room, basement, or utility closet and is the unit that produces heat for the house. Attached to it is the flue or vent pipe, which runs through the wall or up through the roof and carries combustion gases out of the home.
The air handler and blower assembly move conditioned air into the duct system once the furnace has done its work. A thermostat mounts on an interior wall and serves as the control point, while a filter housing sits at the return-air opening to catch particulates before air reaches the furnace itself.
The drawing shows a general layout of these components, and a licensed contractor determines exactly what applies to your house.
