Commercial HVAC repair for New Orleans restaurants, offices and shops
A warm dining room on a Friday or a server closet running hot costs real money by the hour. We repair rooftop units, commercial split systems and small chillers, and we answer 24/7.

Most commercial cooling failures in New Orleans come down to a failed compressor contactor, a clogged condensate drain, dirty condenser coils or an economizer stuck open on a humid day. We diagnose rooftop package units and split systems on the first visit and carry the common electrical parts, so many repairs finish the same trip.
Signs a commercial unit needs service now
- Space temperature climbing through the afternoon
- Rooftop unit short cycling or tripping on high pressure
- Water dripping from ceiling tiles near the air handler
- Humidity high even while the unit runs
- Burning smell or loud rattling from the roof
- Economizer damper stuck open on a humid day
- Server room temperature alarm going off
Commercial cooling in a city that stays humid
Updated September 2026
Commercial systems work harder here than the load calculation suggests. Kitchens add heat and moisture, doors open constantly on a busy block, and outside air brought in for ventilation arrives at high humidity most of the year. A system that is only slightly undersized or slightly dirty shows it fast.
We work on the equipment most small and mid-size businesses run: rooftop package units, commercial split systems, ductless systems for server rooms and additions, and the controls that tie them together.
How a commercial service call runs
- 1
Call and triage
We ask what is down, what it serves and when the space is occupied.
- 2
Dispatch and access
Roof access, keys and a contact on site are arranged.
- 3
Diagnosis
Electrical, refrigerant, airflow and controls checked on the failed unit.
- 4
Quote before work
The repair and price in writing for your approval.
- 5
Repair
Common parts from the truck; larger parts ordered with a date.

Report
What failed, what we did and what to watch on the other units.
Restaurant and Retail Cooling
Restaurants fight two loads at once: the kitchen line and a full dining room. Make-up air, grease on condenser coils near the exhaust, and drain lines that clog with kitchen humidity are the common failures. Retail adds door traffic and lighting heat. We check the condenser coils, drains and airflow on every call, not just the part that stopped, because a clean coil is often the difference between a unit that holds temperature on a Saturday afternoon and one that trips.
Office HVAC
Offices usually fail more quietly: one side of the floor too warm, a conference room that never cools, or humidity that makes paper curl. Zoning dampers, thermostat programming, failed VAV boxes on larger systems and short-cycling rooftop units are the typical causes. We balance what is there before recommending new equipment, and we can schedule repairs early or late to keep the office working. Humidity complaints get a meter reading, not a guess, because the fix for a damp office is different from the fix for a warm one.
Server Room Cooling
A server closet cannot wait until Monday. Most small server rooms here are cooled by a ductless mini-split or a dedicated split system that runs around the clock, which means filters, drains and coils need more attention than a comfort system gets. We repair these units, check that the condensate is draining away from the equipment, and can add a second unit for redundancy where losing cooling is not an option. A simple high-temperature alarm is cheap insurance too, and we can recommend one when we are there.
How long the space is without cooling
Electrical repairs, drain clearing and coil cleaning are usually finished on the first visit. Compressors, motors and control boards for commercial units are sometimes ordered, and we tell you the lead time when we quote.
Commercial buildings in the historic districts
Much of the commercial stock in older parts of the city sits in historic districts where buildings run to the property line and there is no yard for equipment. The preservation commission reviews wall-mounted condensers and exposed conduit on those facades, so in places like the Marigny and Bywater a replacement is planned around what the review will allow, not just what fits. Repairs to existing equipment in place do not raise that question.
Brands we service and install
We repair and install Trane, Carrier, Lennox, Goodman, Rheem, Ruud and the other major lines, plus Mitsubishi Electric ductless.
What drives the cost of a commercial HVAC repair
We quote commercial repairs after diagnosis, not from a list.
Equipment type
Rooftop package units, splits and ductless systems each carry different part costs.
Access
Roof access, lifts and after-hours building rules add labor.
Tonnage
Larger units carry larger compressors, motors and coils.
Refrigerant
Older equipment on phased-out refrigerant limits repair options.
Urgency
Nights, weekends and holidays cost more at most shops.
Controls
Economizers, building automation and zoning add diagnostic time.
Questions about Commercial HVAC Repair in New Orleans
Yes, 24/7. After-hours calls are dispatched by urgency, and a restaurant or server room without cooling is treated as urgent.
Yes. Rooftop package units are a large share of our commercial work, including economizers, belts, compressors and curb adapters.
We service all the major commercial lines, including Trane, Carrier, Lennox, York, Rheem and Daikin, and repair any unit we can get parts for.
Often, yes. Planned repairs can be scheduled early or late to avoid disrupting service or staff.
Yes. Quarterly or seasonal visits with filter changes, coil cleaning and a written log for each unit.
Common causes are too much outside air, an oversized unit short cycling, or a dirty coil. We check airflow and humidity before recommending a fix.
Yes. A clogged drain near electronics should be handled the same day. Shut the unit off if water is near equipment and call.
Yes, when repair no longer makes sense. We quote replacement separately and plan it around your hours.
