Chimneys, Ducts and Dryer Vents in Delaware Township, NJ
Delaware Township meets the Delaware River on its southwest side, with Sergeantsville near its middle and farms, creek valleys and old villages all around. Fuel oil heats more than half of its homes, so the chimney and the boiler are usually the first things to look at.
The township was set off from old Amwell Township in 1838 and covers about 37 square miles of Hunterdon County, part of it on the Hunterdon Plateau and the southern part in the Amwell Valley. The Delaware River and the Delaware and Raritan Canal run along its southwest side, across from Bucks County, Pennsylvania. Raritan Township borders it on the east, East Amwell to the southeast, and Flemington is a short drive out Route 12. It counted 4,560 residents in the 2020 census.
Nearly all of the township's homes are detached houses, by census estimates; about one in five went up before 1940, and the largest later groups date from the 1980s, 1990s and 2000s. Oil is the main fuel, with propane, gas and electricity well behind and a few homes still heated by wood.
Sergeantsville, Rosemont and the covered bridge
Sergeantsville sits near the middle of the township and holds the municipal building, the school and the post office. It was called Skunktown until the post office brought its present name in 1827, and its annual house tour, Thanksgiving in the Country, began in 1973. West of the village, Green Sergeant's Covered Bridge, built in 1872 and rebuilt from its original materials in 1961, crosses the Wickecheoke Creek; it is the last historic covered bridge in New Jersey. Rosemont, Raven Rock and Locktown each carry National Register listings of their own.
The older houses were built to be warmed by fireplaces and stoves, their ductwork came much later, and many still use a big masonry chimney for a boiler, a fireplace or both. Chimney Cleaning sweeps each flue in use and clears the base and the smoke chamber, with the damper checked on the fireplace side.
Oil heat and what a fuel switch does to a chimney
An oil boiler leaves soot and acidic scale in its flue, which flakes off and piles up at the cleanout. When a house moves from oil to propane or to a heat pump, the chimney changes jobs: a new condensing appliance may vent through a side wall and leave the flue empty, or a propane boiler may go back into the old masonry and call for a liner sized to it.
Chimney Repair handles the liner work, along with crowns opened by freeze and thaw, loose flashing and a rusted cap. Before any fuel switch, a sweep and an inspection show what the chimney can still do.
Central air in a boiler house
With a boiler doing the heating, the ducts exist for the air conditioning. The air handler usually sits in the attic, runs hard in the hottest weeks and sits still for months, and its return draws attic dust through any leaky joint. Air Duct Cleaning covers the supply runs, the return, the blower and the coil. Air Duct Repair seals the joints and rehangs runs that sagged, and Air Duct Installation adds a return upstairs when the original system had one grille for the whole floor.
The dryer in these houses often lives in a mudroom or an addition, with a long run to reach the outside. Dryer Vent Cleaning clears it from the machine to the hood, and Dryer Vent Installation swaps foil, or a run with too many turns, for rigid metal.
Creek valleys, the river road and damp air
The Wickecheoke rises on the plateau and drops through the Rosemont valley to the Delaware at Prallsville, and the USGS listed it among the Hunterdon creeks that flooded in the remnants of Ida in September 2021. Houses low in the creek valleys and along the river road can keep damp lower levels, where a return draws moist air and a coil stays wet. Mold Treatment and Removal cleans up growth on the coil, the drain pan and the duct beside them. A lamp at the coil, put in under HVAC UV Light Installation, is a layer between cleanings, never a replacement for a dehumidifier or a clear drain line.

Questions and answers
We are switching from oil to propane. What happens to the chimney?
It depends on the new appliance. A condensing unit vents through the wall and leaves the flue unused, while a non-condensing propane boiler usually goes back into the chimney and calls for a liner sized to it. Have the flue swept and inspected before the installer arrives, so any liner work is planned.
Our farmhouse sits in the Rosemont historic district. Will duct or chimney work change how it looks?
Cleaning ducts, vents and flues leaves no mark on the outside of the house. Where a new chimney cap or vent hood is called for, we show you the part before it goes on and choose one that suits the house.
The air handler is in our attic. How often should the ducts be cleaned?
There is no fixed calendar. Look at the return grille, the filter slot and the coil: heavy dust at the return, debris at the registers or growth on the coil means it is time. We open those points on the first visit and tell you what they show.
Is Sergeantsville its own town?
No. Sergeantsville is an unincorporated village near the center of Delaware Township, home to its municipal building, school and post office. Raven Rock, Rosemont, Locktown and Prallsville are Delaware Township places too, while Stockton, carved out in 1898, is a separate borough.
