New rooftop units and commercial split systems for New Orleans businesses
A commercial replacement has to fit the load, the roof, the code and the business calendar. We plan all four, then install with as little disruption to your hours as the job allows.

Commercial HVAC installation in New Orleans usually means replacing a rooftop package unit or installing split systems for a light commercial space. The job starts with a load calculation for the space and its use, a mechanical permit, and crane or roof-access planning, and is scheduled around business hours so the space keeps operating.
What makes a commercial install different
Updated September 2026
Commercial spaces carry loads that homes do not: kitchen equipment, lighting, doors opening all day, and ventilation air brought in at high humidity. Equipment sized from the old unit's label, or from square footage alone, often ends up fighting humidity all summer.
We start from how the space is used, then plan the equipment, the roof or pad work, the electrical and the schedule, so the business knows exactly when the old system goes off and the new one comes on.
What drives the cost of a commercial installation
Commercial installs are priced after a site visit; these are the main variables.
Tonnage and type
Package units, splits and multi-unit systems vary widely.
Roof work
Curb adapters, new curbs and roof penetrations add cost.
Crane and access
Lifts, street permits and roof access are part of the job.
Electrical
Service and disconnect upgrades where required.
Controls
Economizers, programmable thermostats and building controls.
Scheduling
Night or weekend installs to keep the business open.
What every commercial install includes
- Load calculation for the space and its use
- Mechanical permit and inspection
- Crane and roof access planning
- Curb, pad or stand work as needed
- Gas, electrical and condensate connections
- Economizer and controls commissioning
- Old equipment removed and recycled
Rooftop package unit or split systems
| Rooftop package unit | Split systems | |
|---|---|---|
| Equipment location | All on the roof | Condenser outside, air handler inside |
| Zoning | One unit per zone | Easy to split by area or tenant |
| Service access | Roof access needed | Indoor unit reachable from inside |
| Best fit | Single-story retail and restaurants | Offices, clinics, multi-tenant spaces |
Rooftop Package Units
Most small and mid-size commercial buildings here run on rooftop package units that hold the compressor, coils and blower in one cabinet. Replacement means matching or adapting the roof curb, arranging a crane lift, reconnecting gas and electrical, and commissioning the economizer and controls. We check whether the existing curb fits the new unit before quoting, because a curb adapter or a new curb changes the roof work and the schedule, and we would rather you know that at quote time.
Split Systems for Light Commercial
Offices, clinics and retail spaces often use split systems: condensers on a pad or roof and air handlers above the ceiling or in a closet. They are easier to zone by tenant or area and simpler to service than one large unit. We lay out the equipment, refrigerant lines, condensate drainage and thermostats so each area can be controlled on its own, and we plan drain routing carefully, because a clogged drain above a ceiling grid is an expensive problem.
Tenant Build-Outs
When a space is being built out for a new tenant, the HVAC has to match the new layout, occupancy and equipment, not the last tenant's. We work from the drawings with the general contractor, size and place the equipment, run the ductwork or refrigerant lines, and coordinate inspections with the rest of the build. Getting the HVAC right before the ceiling closes costs far less than fixing hot spots after the tenant moves in. It also keeps the opening date from slipping over a mechanical inspection.
Permits and scheduling on commercial jobs
Commercial HVAC replacements in New Orleans need a mechanical permit and inspection, just like residential ones, and on a commercial job the permit is part of the schedule, not an afterthought. We file it early so the crane date and the inspection line up. We also do not build utility rebates into commercial proposals this year, because the Entergy Louisiana programs are paused.
