Most HVAC companies order their fittings and wait. We make ours. Hoffner Heating & Air runs its own sheet metal fabrication, so when your job needs a transition, boot, or trunk line that doesn’t exist in a supplier catalog, we build it to fit your house instead of forcing your house to fit a catalog part.

If you landed here looking for duct cleaning, we discontinued that service. We’d rather tell you straight than sell you something we no longer do. What we do every week: designing, building, installing, repairing, and modifying the ductwork itself, the part of the system that actually determines whether conditioned air reaches your rooms.
Rooms that never cool down. A second floor that’s ten degrees off. A furnace that’s plenty big but can’t seem to keep up. These are usually duct problems wearing a furnace costume, undersized returns, crushed flex runs, trunk lines that were never designed for the load they carry. We measure, calculate, and design duct systems around the airflow your equipment actually needs. If one room is always the problem child, start with our guide: why one room is hotter or colder than the rest.
Off-the-shelf fittings assume an off-the-shelf house. Pittsburgh’s housing stock, stone basements, tight joist bays, century-old framing, is anything but. Our in-house sheet metal fabrication means custom plenums, transitions, boots, and offsets cut on our CNC plasma table for a precision fit, sized to the job, not to a catalog page.
Our CNC plasma table precision-cuts sheet metal for the plenums, transitions, boots and offsets each job requires.

We fabricate custom sheet metal in-house, plenums, transitions, boots, offsets, sized to the job.
Often, yes. Before blaming the furnace or AC, the duct path to that room needs checking: size, length, crushed sections, and whether the room has a return path.
