Custom Ductwork in South Jersey | B & B Heating & Air Conditioning Inc

Custom Ductwork Design & Fabrication for Better Comfort and Efficiency

At B & B Heating & Air Conditioning Inc, we do more than just install HVAC systems — we engineer the airflow that powers them. Our in-house custom ductwork design and fabrication services are built to improve comfort, energy efficiency, and system performance in homes and light commercial spaces across South Jersey.

Whether you're remodeling, building new, or struggling with uneven airflow, our ductwork solutions deliver the precision your system needs — all crafted right here in our Berlin, NJ facility.

Why Custom Ductwork Matters

Your HVAC system is only as good as the ductwork behind it. Poorly sized, aging, or leaky ducts can undermine even the most advanced heating or cooling system. Unfortunately, many homes — especially older ones — were built with duct systems that don’t meet today’s performance standards.

Systems that short cycle or overwork

Custom ductwork ensures your system delivers air evenly and efficiently to every part of your space — helping your HVAC equipment work smarter, not harder.

Duct Sealing, Repairs & System Modifications

You don’t always need to replace your entire duct system. Our technicians also provide:

  • Duct inspections for airflow and leakage
  • Sealing of joints and gaps
  • Duct resizing or re-routing
  • Air balancing for even room-to-room comfort

In-House Ductwork Fabrication Facility

Unlike many HVAC companies, B & B has a fully equipped ductwork fabrication shop on-site at our Berlin, NJ location. That means we can build what your project needs — fast, accurate, and to spec — without relying on third-party suppliers.

Why Choose B & B for Ductwork Fabrication?

Most HVAC contractors outsource ductwork — which leads to delays, poor fit, and higher costs. We design and build everything under one roof to ensure quality control and speed.
