Commercial Load Calculations
We calculate heating and cooling loads using occupancy, lighting, equipment heat, glazing, and outdoor air requirements so the new system is sized correctly for the building instead of matched to old equipment.

Roswell Commercial HVAC Installation
Commercial HVAC installation in Roswell for offices, retail, restaurants and warehouses: load calculations, rooftop units, VRF and phased startups.
Roswell, Georgia
Commercial HVAC Installation in Roswell, GA
A new commercial system has to fit how your building actually runs: occupancy patterns, equipment heat, ventilation requirements, and the hours your doors are open. Roswell HVAC plans and installs heating and cooling for offices, retail storefronts, restaurants, warehouses, schools, and government facilities across North Fulton. We start with a load calculation and a review of existing ductwork, electrical service, and roof structure, then recommend equipment sized for the space rather than guessed from square footage. Rooftop package units, split systems, ductless and VRF systems, and make-up air for kitchens are all part of our work. For tenants who cannot close, we phase the project and schedule the heaviest work after hours or on weekends. If you are planning a buildout or replacing aging equipment, talk with our team about commercial HVAC installation in Roswell and get a clear scope before work begins.

Commercial HVAC Installation Services in Roswell
Rooftop Unit Installation
We set packaged rooftop units with crane coordination, curb adapters, gas and electrical connections, and condensate routing, then verify airflow and economizer operation before the unit is turned over to you.
VRF and Ductless Systems
Variable refrigerant flow and ductless systems give multi-zone buildings independent temperature control. We design refrigerant piping, branch selectors, and controls so each office or suite stays comfortable year round.
Split Systems and Air Handlers
For buildings without rooftop access, we install split condensing units with indoor air handlers or furnaces, sizing refrigerant lines and supply trunks to match the floor plan and ceiling space available.
Ventilation and Make-Up Air
Restaurants, gyms, and classrooms need controlled outdoor air. We install make-up air units, energy recovery ventilators, and exhaust balancing so kitchens vent properly and occupied rooms stay fresh without wasting energy.
Controls and Building Automation
Programmable thermostats, zone controllers, and building automation integration let you schedule setbacks around business hours. We configure sequences, label equipment, and show your facility staff how to adjust settings.
Why Choose our Commercial HVAC Installation Experts in Roswell
Commercial installations involve more moving parts than residential work: permits, landlord approvals, crane lifts, electrical upgrades, and tenants who still need to operate. Our team plans each step in advance, coordinates with general contractors and property managers, and keeps the jobsite clean so your business can keep serving customers during the project.
We recommend equipment based on measured loads and long-term operating cost, not the biggest unit available.

FAQ
Commercial HVAC Installation FAQs
Answers to the questions Roswell customers ask us most. Still unsure? Call (770) 661-0066.
What affects the cost of a commercial HVAC installation?
Cost depends mainly on building size, the number of zones, equipment type, and how much existing ductwork and electrical service can be reused. Crane lifts, roof curb changes, permits, and after-hours labor also play a role. We walk the site, review drawings, and provide an upfront written quote before any work is scheduled.
How long does it take to install a new rooftop unit?
A straightforward like-for-like rooftop unit swap can often be completed in a day once equipment and crane time are scheduled. Projects that require new curbs, structural review, gas line changes, or electrical upgrades take longer. We give you a realistic timeline during the site survey so you can plan around tenants and staff.
Can you install new equipment without shutting down my business?
In most cases, yes. We phase work by zone so part of the building stays conditioned, and we schedule crane lifts, ductwork tie-ins, and electrical shutdowns for early mornings, evenings, or weekends when possible. Before work starts, we agree on a schedule with your property manager so nobody is caught off guard.
Is a VRF system a good choice for a Roswell office building?
VRF works well for offices with many small rooms or suites that need independent temperature control, and it handles Roswell's long cooling season efficiently. It does require careful refrigerant piping design and a higher level of controls setup. We compare VRF against rooftop or split options based on your floor plan, budget, and how the space is used.
Do I need a permit for commercial HVAC replacement?
Yes, commercial HVAC installations and most equipment replacements require mechanical permits, and electrical or gas work may need separate permits and inspections. Requirements vary by jurisdiction, so we confirm what applies to your property in Roswell or neighboring cities and handle the paperwork and inspection scheduling as part of the project.
