Air Duct Installation in Somerville, NJ

Each supply is sized for the room it serves, and the trunk it comes off has to carry the added load without taking air from the rooms already on it. The crew looks at the furnace or air handler's capacity first, because new runs on equipment that is already at its limit leave every room short. Returns are planned along with the supplies, so each part of the house has a way for air to get back.

Runs are kept as short and direct as the framing allows, with the fewest elbows the layout needs. Trunks and long straight runs are sheet metal, and insulated flex is kept to short connections where it can lie straight and fully stretched. Every joint, seam and boot is sealed with mastic as it is installed, and any duct passing through an unconditioned attic, garage ceiling or crawl space is insulated so it is not fighting the outdoor temperature along its length. Dampers go in wherever a branch will need balancing later.

A finished basement in a house built in the 1980s or 1990s usually has the trunk running through it, so new registers come off that trunk on short branches. The mistakes to avoid are familiar ones: registers cut straight into the side of the trunk, no return from the new space, and ceilings closed over joints that were never sealed. The crew adds supplies and a return for the finished rooms and sets the dampers so the floors above keep their share.

An addition or a room over the garage usually sits at the far end of the system, as far from the equipment as it can be. Where the existing trunk cannot carry the new room, a separate branch is run back toward the plenum, or the crew tells you plainly that the equipment should get a look from your heating contractor first. In the two-story houses of Montgomery, Branchburg and Hillsborough, the attic air handler serving the second floor is often the tie-in point for a new bedroom or bonus room.

Yes, with planning. Many houses in Somerville's older neighborhoods, in Raritan, and in the historic districts of Rocky Hill and Millstone went up long before central air, and a house heated by a boiler and radiators has no ductwork to build on. Adding a system means finding routes through plaster walls, closets, attic floors and basement ceilings while opening as little of the house as the layout allows. One workable plan is an attic air handler feeding the upper floor through ceiling registers, with a separate route for the first floor.

In the historic districts, where trim, plaster and facades are much of what makes the houses worth keeping, grille locations and any exterior opening are agreed with you before the layout is final. The work is planned around a household still living in the house, with dust barriers at each opening and the work area cleaned at the end of each day.

In the flood-prone parts of Manville, and in Somerville houses near Peters Brook, ductwork that took on water is replaced rather than cleaned, following the EPA's guidance that wet duct insulation cannot be cleaned effectively. The rebuild is also a chance to raise the trunk into the joist bays, keep branches off the basement floor, and straighten out a layout that was pieced together over the years. If the furnace or air handler was replaced after the water, the new ductwork is matched to that equipment.

The free estimate happens at the house: rooms measured, the equipment and the trunk inspected, and the proposed route walked with you before a price is given. The company is licensed and insured, registered as NJ HIC 13VH13654300, veteran owned, and books installation visits across central Somerset County 8 AM to 8 PM, 7 days a week. If the project includes a laundry room, the dryer vent installation gets laid out at the same time, while walls and ceilings are still open, and older runs that stay in service get an air duct cleaning so construction dust does not blow into the new rooms.
