Load and Duct Design
We calculate heat gain and loss for each room, then size trunks, branches, and returns so airflow matches what your equipment and floor plan actually need throughout the year.

Ductwork Installation in Roswell, GA
A heating and cooling system can only perform as well as the ducts that carry its air. Undersized runs, crushed flex duct, and poorly planned layouts cause hot and cold rooms, noisy registers, and equipment that works harder than it should. Our ductwork installation in Roswell service covers full replacements, new construction, additions, and finished basements. We start with a room-by-room load calculation and design the system using Manual D principles so each space gets the airflow it needs. From there we fabricate or select sheet metal trunks, rigid or flex branches, and properly sized returns, then seal every joint with mastic and insulate runs that pass through attics and crawlspaces. Many older homes near Historic Roswell still have original duct systems that were never designed for modern equipment, and a well-planned replacement often makes a noticeable difference in comfort.

Full Duct Replacement
Aging, leaky, or poorly routed systems are removed and replaced with new trunks and branches, often rerouted to shorten runs and cut down on restrictive bends and transitions.
New Construction Systems
For new homes and commercial buildouts, we coordinate with builders to plan duct chases, register locations, and return paths before walls close in, avoiding costly compromises later.
Additions and Basements
When you add square footage, we evaluate whether existing equipment and ducts can serve it, then extend the system or recommend a separate solution such as a dedicated zone.
Return Air Upgrades
Many homes have too few or undersized returns. Adding properly sized return paths reduces static pressure, quiets the system, and helps the blower move air without straining.
Sealing and Insulation
Every seam and connection is sealed with mastic or approved tape, and runs in unconditioned attics or crawlspaces get insulation rated for the location to limit heat loss and condensation.
Why Choose our Ductwork Installation Experts in Roswell
Duct design is often an afterthought, and many comfort complaints trace straight back to it. Our team treats ductwork as engineered infrastructure, not just pipe between the furnace and the vents. We measure, calculate, and plan before cutting anything, and we explain the layout so you know exactly why each run goes where it does.
Clean installation matters too. We use proper hangers and supports, avoid kinked or overstretched flex duct, and keep attic and crawlspace work neat. Because we also install and service the equipment itself, we can match new ducts to your system's blower capacity and make sure the whole setup works together from the first day it runs. For homes in Roswell, Alpharetta, and Milton, that means a duct system planned around long cooling seasons rather than a generic layout copied from another job.

Once the system is connected, we measure static pressure and airflow at registers, adjust dampers to balance rooms, and walk you through the finished layout and filter location.
FAQ
Ductwork Installation FAQs
Answers to the questions Roswell customers ask us most. Still unsure? Call (770) 661-0066.
How do I know if my ductwork needs to be replaced?
Replacement is worth considering when ducts are badly leaking, crushed, poorly insulated, or simply undersized for your equipment. Warning signs include rooms that never reach temperature, whistling registers, high static pressure readings, and visible damage in the attic. Older homes around Historic Roswell often have original ductwork that was never designed for modern systems, so an inspection is a good first step.
What determines the cost of new ductwork?
The main factors are home size, the number of rooms and returns, attic or crawlspace access, material choices such as sheet metal versus flex duct, and whether old ducts need removal. Design changes like added returns or rerouted trunks also affect labor. We measure and inspect first, then provide an upfront written quote before any work is scheduled.
How long does a ductwork installation take?
A full replacement in a typical home usually takes one to three days, depending on size, access, and how much rerouting is involved. Additions or a single new branch can often be done in a day. We plan the work so your system is offline for as little time as possible and confirm the schedule with you in advance.
Should I replace my ductwork when I replace my AC or furnace?
It is often the best time to evaluate it, but not every system needs new ducts. If existing ducts are sound, properly sized, and well sealed, they can serve new equipment fine. If they are leaky or undersized, new high-efficiency equipment may never deliver its rated performance, so we test the ducts and recommend replacement only when it is justified.
Is sheet metal or flex duct better?
Each has a place. Sheet metal trunks are durable, smooth inside, and resist damage, which makes them ideal for main runs. Flex duct is practical for short branch connections in tight attic spaces, as long as it is fully stretched, supported, and not kinked. Most well-designed residential systems combine both, matching the material to the location and airflow needs.
