New construction HVAC in Roswell for custom homes, additions and commercial builds: load calculations, duct design, rough-in and startup on schedule.
Designing heating and cooling during construction is far easier and less expensive than correcting mistakes after drywall goes up. Roswell HVAC works with builders, general contractors, and homeowners on new homes, additions, and light commercial projects throughout Roswell and North Fulton. We begin with room-by-room load calculations based on the plans, insulation levels, window specifications, and orientation, then design duct layouts that deliver balanced airflow to every space. Equipment selection accounts for Georgia's long, humid cooling season, so systems control moisture instead of simply chilling the air. Our crews coordinate rough-in with framers, plumbers, and electricians to keep the project on schedule, and we return for trim-out, startup, and testing before closing. Need a dependable mechanical partner for your next build? Talk with us about new construction HVAC in Roswell early in the planning stage.
We calculate heating and cooling loads from the construction drawings, factoring insulation values, window performance, ceiling heights, and orientation, so equipment is sized for the finished building rather than estimated.
Supply and return ducts are laid out to fit framing, trusses, and soffits while keeping runs short and properly sized. Good design prevents noisy registers, weak rooms, and pressure imbalances.
We help you choose between heat pumps, gas furnaces with air conditioners, ductless systems, or hybrid setups, balancing efficiency goals, fuel availability, budget, and the comfort expectations of future occupants.
Our crew installs ductwork, refrigerant lines, condensate drains, gas piping connections, and thermostat wiring during framing, coordinating with other trades so inspections pass and schedules stay on track.
Tighter modern homes need planned fresh air. We incorporate bath and kitchen exhaust, fresh air intakes, or energy recovery ventilators, and can add filtration upgrades during construction at lower cost.
After finishes are complete, we set equipment, install registers and thermostats, charge refrigerant, verify airflow to each room, and confirm the system performs as designed before move-in.
Builders need subcontractors who show up when scheduled, communicate clearly, and pass inspections the first time. We provide written scopes, coordinate directly with your superintendent, and keep our work areas organized so other trades can move forward without delays.
Homeowners building custom homes benefit from the same attention. We explain equipment options in plain language, discuss zoning for multi-story layouts, and point out decisions that affect long-term comfort and operating costs, like duct placement inside conditioned space. Our goal is a system that runs quietly, keeps humidity under control, and holds even temperatures from the basement to the bonus room. From Roswell to Milton and Alpharetta, we bring careful design and clean installation to every new build we take on.

We review architectural plans, run load calculations, and design the duct layout and equipment package. You receive a detailed proposal and schedule aligned with your construction timeline and inspection milestones.
During framing, our crew installs ductwork, line sets, drains, and control wiring, coordinating with other trades and scheduling the mechanical rough-in inspection so drywall can proceed on time.
Once finishes are complete, we set equipment, install grilles and thermostats, start the system, measure airflow and refrigerant charge, and walk the owner or builder through operation and maintenance.
FAQ
Answers to the questions Roswell customers ask us most. Still unsure? Call (770) 661-0066.
Ideally during design, before framing begins. Early involvement lets us plan duct chases, equipment locations, and return paths so ducts are not squeezed into whatever space is left. Changes are simple on paper and expensive after framing, so involving us at the planning stage saves time and avoids compromises later.
Cost depends on home size, number of stories and zones, equipment type and efficiency, duct layout complexity, and ventilation requirements. Features like zoning, air purification, or ductless rooms also affect the total. We review the plans and provide an upfront written quote that itemizes the scope for the builder or homeowner.
When possible, yes. Ducts inside the conditioned envelope lose far less energy than ducts in hot attics, which matters during Roswell's long summers. Options include dropped soffits, conditioned attics, or running ducts between floors. We discuss what is practical for your plans and budget during the design stage.
Both work well here. Heat pumps provide efficient heating and cooling with one system and suit Roswell's mild winters, while gas furnaces paired with an air conditioner deliver strong heat during cold snaps. Dual-fuel systems combine both. We help you compare based on fuel availability, efficiency goals, and comfort preferences.
HVAC work happens in two main phases. Rough-in usually takes a few days after framing, depending on home size and complexity, followed by inspection. Trim-out and startup happen near the end of the project once finishes are complete. We coordinate both phases with your builder's schedule to avoid delays.
