Proper duct design ensures that your HVAC system delivers balanced airflow to every room, operates efficiently, and maintains consistent temperatures throughout your home or building. Poorly sized or routed ductwork can cause hot and cold spots, noisy airflow, excessive energy use, and premature equipment wear.
Custom fabrication involves creating sheet metal ducts, transitions, plenums, and fittings specifically for your HVAC system layout. Unlike stock parts, custom ductwork is built to match your home's exact dimensions and airflow requirements, resulting in tighter seals, better efficiency, and a cleaner installation.
We primarily use galvanized sheet metal, which is durable, corrosion-resistant, and ideal for both residential and commercial HVAC applications. In some situations, we may use flexible ducting (for short runs or tight bends), but rigid metal ductwork offers superior airflow, sealing, and lifespan.
Not necessarily—but it has limitations. Flex duct can be helpful in tight spaces, but it's more prone to airflow restriction, sagging, and leakage if not properly supported or installed. At RJ's, we often use a hybrid approach: rigid ductwork for main runs and flex for short final connections.
You may need duct replacement if you experience:
An inspection can reveal whether sealing, rerouting, or full replacement is the best solution.
Yes! We design and install custom ductwork for home additions, finished basements, second-story expansions, and remodels. We ensure your new space receives balanced airflow and that your existing system is properly sized and zoned for the added demand.
Duct sizing is based on Manual D and Manual J load calculations, which consider room size, insulation, windows, and HVAC equipment capacity. Proper sizing ensures that each register receives the right amount of airflow—too small causes noise and restriction; too large reduces system performance.
By fabricating ductwork in-house, RJ's provides:
It also ensures we can handle any on-site modifications without delay.
We seal joints and seams using mastic sealant, foil-backed tape, or duct sealant depending on the application. Proper sealing reduces air leakage, energy loss, and contamination, and is especially important in attics, basements, or crawl spaces.
Yes. Insulated ducts reduce heat gain or loss, maintain air temperature, and prevent condensation in unconditioned spaces. For ducts running through attics or basements, R-6 or higher insulation is standard. We ensure all new ductwork meets or exceeds current energy code.
Absolutely. Noise often comes from improper duct sizing, sharp bends, or turbulent airflow. We can reduce HVAC noise by:
For a full duct replacement in an average-sized home, installation takes 1–3 days, depending on access and scope. New construction installations may be phased with other trades. We coordinate all work to minimize disruption and ensure clean, code-compliant results.
Yes. We provide duct fabrication and installation for retail shops, offices, restaurants, medical suites, and other light commercial spaces. Our team works with general contractors, architects, and business owners to deliver custom HVAC duct systems that meet performance and code standards.
Yes. New or properly sealed ductwork can improve system efficiency by 20% or more by eliminating leaks, pressure imbalances, and restrictions. When paired with high-efficiency HVAC equipment, optimized ductwork ensures your investment pays off in both comfort and lower energy bills.
