Air Ducts and Dryer Vents in the Borough of Raritan, NJ
Raritan is the old mill borough on Somerville's western edge, home to 7,835 people at the 2020 census on 2.03 square miles, and not to be confused with Raritan Township in Hunterdon County. Its houses run from the mill years through the postwar decades to new apartments on the woolen mill's former ground.
The village became the town of Raritan in 1868 and a separate borough in 1948. A water power canal dug in 1840 drew industry along its banks, and the Raritan Woolen Mills, founded in 1846, made uniforms for the Union Army and stayed the area's largest employer through the 1930s and 1940s. Census estimates date a fifth of the borough's housing before 1940 and more than a quarter to the 1950s and 1960s, so a typical street mixes houses heated before central air with houses built around a basement furnace.
Two-family buildings hold a large share of Raritan's homes, and half of its households rent, so many visits involve an owner, a tenant and two of everything. Air duct cleaning takes in both systems, the dryer vent cleaning takes in both runs, and the notes go to whoever pays for the work. Somerville borders the borough to the east, Hillsborough lies across the river, and Route 202 carries on west to Branchburg, so this part of Somerset County shares one crew and one schedule.
Two-family houses and two sets of ducts
In a two-family house each unit usually has its own furnace, both standing in the one basement. The lower unit's supplies are short and simple. The upper unit's runs climb through first-floor walls, old closets or a chase beside the chimney, and a joint that opens anywhere along that climb heats the downstairs hallway instead of the bedroom it was meant for. Smells can travel the same path, which is how cooking from one apartment reaches the other. Air duct repair seals those joints, and it often settles a tenant complaint that a cleaning alone would not.
Two units also mean two dryers. The upstairs machine often vents down through the lower unit's ceiling or sideways across the house to reach an outside wall, a long run with low spots where damp lint settles. Where that route uses foil or plastic hose, or turns more times than the dryer can push through, dryer vent installation lays in rigid pipe with fewer turns and no sags.
Postwar blocks and the cooling that came later
A house from the 1950s or 1960s was usually built with a basement furnace, a rectangular trunk down the middle and round branches to each room, sized for heat. Central air arrived later as a coil set on top of that furnace, and cooling asks the same ducts to carry more air than they were drawn for. Upstairs rooms that never cool down are often the sign, and the answer can be a larger return or a new branch through air duct installation rather than another cleaning.
That coil sits over a basement that holds humidity in August, so the coil and the drain pan beneath it are the first things we inspect. Where growth has taken hold on those surfaces or inside the plenum, mold treatment and removal takes care of that equipment and the ducts joined to it. HVAC UV light installation can follow as an added layer, alongside a filter changed on time and a pan that drains, because the lamp does nothing about the moisture itself.
Chimneys from the mill years
The borough's prewar houses carry brick chimneys that may hold an unused fireplace flue beside the one serving the furnace. The postwar houses usually have a single flue for the furnace and the water heater, clay-lined inside a block or brick stack. Chimney cleaning clears soot, fallen mortar and the nests that settle into a flue with little heat going up it, and the cleanout door at the base is where that debris piles up first.
Chimney repair covers the top of the stack: a crown cracked by freeze and thaw, a cap that rusted or blew off, flashing that no longer sheds water off the roof. On a two-family house the chimney often serves both furnaces, so a problem at the top affects two households, and we plan the work with both in mind.
Parade weekends, rentals and scheduling
Somerset Street is the borough's main street, and each September the John Basilone parade fills it on a Sunday, honoring the Raritan Marine who received the Medal of Honor for Guadalcanal. A visit that weekend is planned around the route. On rental properties we set the time with the owner and let each tenant know which rooms we need and for how long.

Questions and answers
We own a two-family in Raritan. Can both units be done in one visit?
Yes. We work both furnaces and both duct systems, then both dryer runs, in one visit planned around the tenants. Each unit gets its own findings, so you can see which system carried more dust and which vent was the one packed with lint.
Is this the Raritan in Hunterdon County?
No. This page covers the Borough of Raritan in Somerset County, between Somerville and the Raritan River, along Route 202. Raritan Township near Flemington is a separate municipality in Hunterdon County.
Our upstairs tenant says the dryer needs a second cycle for towels. Where do we start?
With the vent run, not the dryer. The upstairs run in a two-family is usually the longest in the house, and lint packs at its low points and at the hood. We clean it end to end, check the flap outside, and tell you if the route itself needs replacing.
The coil above our furnace smells musty in late summer. Cleaning or a UV light?
Cleaning first. The coil, the pan and the drain line get checked and cleaned, and any growth on the equipment is treated. A UV light can help keep the coil clean afterward, but only when the pan drains and the basement humidity is under control.
