Custom Sheet Metal Work

Custom Sheet Metal Fabrication in New Bern, NC

GP Heating & Cooling is a family-owned and locally-owned company based in New Bern, NC. Many heating and cooling projects stall on one problem: a duct transition, plenum connection or fitting that standard parts cannot match. Our team measures the existing opening, confirms how the air needs to travel and fabricates a custom sheet metal piece to fit it. Backed by 22 years of experience, we build each part around the system it will serve, so the connection seals and delivers the airflow the equipment was designed for.

Our Fabrication Approach

Why New Bern Chooses Our Sheet Metal Company

Custom work only helps when the measurements and the layout are right. These six commitments shape every fabrication job we take on.

  • Family ownership behind every custom cut

    Our company is family-owned, and the people who take your measurements are the same people who answer for the finished piece. A part that does not fit can leak air, strain a blower or leave a room short of airflow, so we treat every dimension as a commitment. You can read about our background on our About Us page.

  • Local ownership that stays in the community

    We are locally owned and operated, and our fabrication work stays with the neighbors who will live with the results. A part we fabricate remains our responsibility long after installation, through every season the system runs.

  • Measure first, then cut

    Every custom piece begins with field measurements of the existing duct, the equipment connection and the surrounding framing. We record those dimensions before any metal is shaped, so the part reflects the actual opening rather than a guess from a drawing.

  • Fit checked at both ends

    A transition joins two different openings. We check the connection at the furnace, air handler or package unit, along with the duct on the other side, so the piece meets both without forcing or leaving gaps.

  • A written scope before fabrication

    You receive a plain-language description of the part, its dimensions and the reason it is needed before we fabricate anything. You can review that scope and ask questions first, so the decision rests on clear information.

  • Experience across ducted systems

    Our work reflects 22 years of experience, and we are an Armstrong ProTeam Dealer and a Ducane dealer. We see how ductwork connects to central air, heat pump, furnace and package systems, which helps us fabricate parts that match the equipment around them.

Share Your Ductwork Details

Tell Us About the Part Your System Needs

Describe the opening or connection that needs a custom piece, including the equipment it joins, its approximate size and any photos you have. Send those details through our contact page, and our team will follow up to arrange a visit. Our technicians come to your home or business to take exact measurements. If the problem turns out to be a leak rather than a missing part, you can compare our furnace repair service and package unit repair service before deciding.

Signs a Custom Part Is Needed

Ductwork Signs That Call for a Custom Piece

Not every airflow problem needs new metal. These six situations often point to a connection or section that a standard part cannot solve, so a closer measurement is worth scheduling.

  • A Transition That Does Not Line Up

    When the duct opening and the equipment connection sit at different heights or angles, a standard transition often leaves a gap or forces the joint. That strain can crack seams, loosen fasteners and let conditioned air escape into the attic or crawl space. We measure both ends and fabricate the transition so the connection meets without force.

  • A Section Damaged Beyond Patching

    A corroded, crushed or separated duct section may be too damaged to hold a seal. Patching can buy time, but repeated patches often leak at their edges. We measure the damaged run, check the surrounding sections and fabricate a replacement piece that matches the original path. Sealing the remaining joints is a separate step, covered by our duct sealing service, and we explain it before recommending work.

  • A Supply Branch That Starves One Room

    When a single room stays cool or warm while the rest of the home responds, the branch serving it may be undersized, misrouted or joined with an improvised fitting. A custom branch or reducer can correct the path without changing the whole system. We record the existing dimensions and confirm the change before fabricating it.

  • An Opening Altered by a Remodel

    Remodeling often changes the framing around a return or supply opening. The new opening rarely matches standard duct sizes, and makeshift fittings can restrict airflow. We take the dimensions of the finished framing and build a piece sized to it, so the connection fits the space as it now exists.

  • An Equipment Swap That Changes the Connection

    A new furnace, package unit or heat pump may have a connection size or position that differs from the unit it replaces. Forcing the old duct to fit can waste capacity and strain the new equipment. A custom piece bridges the difference while keeping the airflow close to the original design.

  • A Return Path That Pulls Dust Into the Space

    Return openings that are too small, poorly located or unsealed can draw dust and unconditioned air into the system. Those conditions can also cause filters to clog sooner than expected. We check return dimensions and fabricate a corrected piece where the opening needs it.

How a Custom Piece Comes Together

From First Measurement to Installed Fit

Each custom job follows the same sequence. The order matters because every later step depends on the measurements recorded earlier.

Step 1 of 5

Review the Opening and the Problem

We start by understanding what the new or corrected piece has to do before we measure anything.

  • Ask which furnace, air handler, heat pump or package unit the piece connects to.
  • Note what the existing duct or opening currently does, including any leaks, noise or uneven airflow.
  • Share any earlier drawings, photos or installation notes you have on hand.
  • Confirm which areas of the home or building the technician will need to access.
  • Identify whether the job is a new connection, a repair or a correction after a remodel.

Components We Fabricate

Custom Components for Precise Fits

Each component below solves a specific fit problem. Every card links to our request form, so you can describe the part your system needs.

  • Transition Pieces

    Transition pieces join a duct to an equipment opening that does not match it in size, shape or height. We measure both ends and build the piece so the connection meets without strain.

  • Custom Duct Sections

    Some runs cannot be completed with standard lengths or angles. A custom section follows the actual path of the duct and keeps airflow smooth through the bend.

  • Branch Fittings and Reducers

    Branch fittings send air toward a room or zone, while reducers adjust the size of a line where capacity changes. Both need accurate dimensions to avoid restriction.

  • Plenum Connections

    A plenum connection links the main air path to the equipment it serves. We fabricate the connection to the recorded dimensions so the joint seals and carries air evenly.

  • Return Air Openings

    Return openings must be sized and placed to draw air without pulling in dust from the wrong areas. We build the opening to the framing that exists in your home.

  • Equipment Connection Adapters

    When a new system differs from the one it replaces, an adapter bridges the difference at the connection point. The adapter is sized to the equipment specifications and the existing duct.

  • Repair Sections

    A damaged section that cannot hold a seal may need a fabricated replacement rather than another patch. We match the replacement to the original path and seal it at each joint.

  • Remodel Openings

    Renovations often leave openings that no standard fitting can serve. We take the dimensions of the finished space and fabricate a piece that matches it.
