Air duct cleaning in Essex County, New Jersey

In Essex County the water arrives through the drain

Four small waterways carry the rain off the Watchung slope into the Passaic, and in most of this county the water does not come over a bank in view of the house. It comes up through the floor drain, in at the base of a foundation wall, or down a driveway into a walkout basement, because the storm system serving a small stream corridor is full. Older parts of the county drain through a combined system that carries storm water and sewage in the same pipes, so what returns up a floor drain is category 3 grossly contaminated water under the ANSI IICRC S500 standard.

The air handler in a Bloomfield, Nutley or Belleville house usually stands in that same basement. Where it ran while the basement was wet, the question of what is in the ductwork is a fair one, and it is answered by an inspection of the supply and the return rather than by a guess.

S520 treats the system as its own part of a remediation

Mold work in this county is written against ANSI IICRC S520, and that standard covers heating and cooling system remediation beside structural and contents remediation. The reason is the stairwell and the return air path: what is disturbed in a contained basement reaches bedrooms on the floor above through the ductwork unless the system is part of the plan.

So a duct line on an Essex County estimate is recommended when the system ran while growth was active, when growth is found on or near the coil or in the return, or when a musty smell arrives at a register rather than at a wall. All three point at the system. Cleaning the ducts never replaces fixing the water that fed the growth.

Plaster on lath, and why the timing matters

Most of the housing between Newark and Montclair predates modern construction: nineteenth century rowhouses in the Newark East Ward, large apartment blocks in East Orange, and Victorian and early twentieth century stock through Bloomfield and Montclair, all plaster on lath over deep cavities. That construction holds water after the surface reads dry, which is why the drying runs longer here and the readings are repeated daily.

The ducts are cleaned at the end of that sequence, once the affected material is out and before the space is closed up. Cleaning a system while the building around it is still wet achieves very little, and the order is what keeps a finished remediation finished.

What whole system cleaning covers

The work follows the NADCA standard, which is the standard duct cleaning is measured against. Whole system means the supply and return ducts, the registers and grilles and the heating and cooling coil, the set of components the Environmental Protection Agency names for a duct cleaning. The system is inspected before the work so the scope is set by what is in it, and inspected again afterwards so there is something to compare. A sanitizing treatment is offered where the scope calls for one, using EPA registered products described as safe around pets and children. Nothing is fogged in place of removal and no ozone is used in an occupied home.

Fifteen Essex County towns, one method

Newark is tidal, dense and divided into five wards. East Orange and Orange are apartment and multi family cities on the Second River. Irvington is attached housing. Belleville sits where the Second River meets the Passaic, Bloomfield is where Toney's Brook joins it at Watsessing Park, and Montclair and Glen Ridge are Victorian and Edwardian stock up on the slope. Livingston, Caldwell, West Orange, Nutley, Millburn, Maplewood, South Orange and Newark's neighbors are all worked by the same IICRC certified technicians.

Routine dryer vent cleaning is the one duct job that does not belong here. It goes to AMG Duct Cleaning, the same owner's dedicated duct company with its own Google profile and its own reviews, and a call here about a dryer vent is passed on to them. A person answers at any hour, the visit is by appointment, and a written estimate comes before the work starts with no hidden fees.
