Custom Ductwork in Pittsburgh, Fabricated on the North Side

Pittsburgh is a city of odd ductwork. The housing stock runs from 1890s rowhouses on the South Side Slopes to postwar brick in Brookline and Penn Hills, with narrow chases, stone foundations, sloped lots and basements that were never meant to hold a modern air handler. Almost nothing is square, and almost nothing standard fits the first time. That is the work this shop was built for: a fitting made to the measurement you actually have, not the nearest stock size.

The shop is on California Avenue on the North Side, in the 15202 ZIP, a few minutes from Route 65 and the McKees Rocks Bridge. Contractors working anywhere in Allegheny County, from Cranberry and Wexford down to Bethel Park and Monroeville, are close enough to talk through a drawing on the phone in the morning and have the piece cut on the same equipment that builds every fitting on this site.

What we fabricate for Pittsburgh

Thirteen fitting types, each built to the dimensions you enter, in galvanized steel, aluminum or stainless steel. Square to round transitions lead the list because they are the fitting most often missing from a stock rack; every other hub works the same way. Open a fitting, enter the size, and the designer prices it as you type.

The size catalog

5,582 published sizes across the thirteen fitting types, each on its own page with a fixed price in galvanized, aluminum and stainless that you can order from directly. The ranges below are the lowest and highest published price for each fitting; the designer prices every size in between.

Pittsburgh houses and the fittings they need

The typical Pittsburgh retrofit is a furnace or heat pump replacement in a basement built for a gravity coal furnace. The old octopus duct comes out, the new unit is smaller and in a different spot, and the trunk has to find its way between joists, a stone wall and a sewer line. That job is mostly offsets, transitions and square to round fittings, because the plenum is rectangular and the branches are round pipe. A plenum sized to the new unit's opening, a transition to the trunk width the joist bay allows, and square to rounds at every takeoff cover most of it.

Rowhouses in Lawrenceville, Bloomfield and the South Side add a second problem: there is no room to run duct sideways. The chase is a closet corner or a boxed-out soffit, and the fitting that saves the job is a reducer or a flat elbow made to the width of the chase instead of the width of the trunk. Because every fitting here is cut from a sheet to your dimensions, a 14 by 6 trunk that has to become 20 by 4 to clear a header is a normal order, not a special.

Hillside houses in Mount Washington, Greenfield and the North Hills often have the mechanical room on a different level than the living space, with the trunk climbing a stair wall. That is where a long offset or a pair of elbows with a short straight between them earns its keep, and where the designer pays off: you can set the exact rise and run and see the piece in 3D before you commit.

Commercial and industrial work in the Pittsburgh area

Restaurant kitchens in the Strip District, Oakland and Shadyside need grease exhaust in welded or fully sealed stainless, and the hood collar is rarely the same shape as the fan inlet. A stainless square to round with a long taper is the standard answer, and it is priced live on the square to round page in stainless as well as galvanized and aluminum.

The region's labs, hospitals and university buildings in Oakland, the machine shops along the rivers and the light industrial parks in RIDC, Neville Island and the Turtle Creek valley all run exhaust and makeup air that was never on a residential size chart. Larger tees, wyes and crosses in heavier gauge, and end caps for cleanouts and future taps, are ordinary orders here.

Working with the shop

Most Pittsburgh customers never call. They open the fitting page, type the dimensions from the job, pick material and gauge, and order at the price the designer shows. When a piece is unusual, an offset outlet on a square to round, a TDC flange on a size the designer does not list, a takeoff from a drawing, call 412.725.2744 or email sales@pmxductwork.com with the dimensions and we will price it from the drawing.

If you are used to driving to a supply house and hoping the fitting you need is on the shelf, the difference is that here the shelf is the whole catalog: every size, in three materials, made to order from the same sheet stock. The published size list below is the set of common sizes with fixed prices; the designer builds everything in between.
