Short answer
Commercial AC repair in New Orleans usually means a rooftop package unit or split system that has stopped cooling because of a failed capacitor or contactor, a broken belt, a clogged coil or filter, a refrigerant leak, or a failed control. A technician checks the unit's controls and safeties first, then the electrical parts, airflow and refrigerant, and quotes the repair before work starts.
Signs a commercial unit is failing
How commercial units fail
Commercial units run longer hours than home systems, often with doors opening all day and kitchens adding heat. That wears belts, fan motors, contactors and capacitors faster, and grease and dust load coils and filters quickly. Many breakdowns are small parts failing under that load.
We start at the controls and safety switches, since economizers, pressure switches and freeze stats can shut a unit down without anything else being broken. We repair Carrier, Trane, Lennox, York and Daikin equipment, and scheduled commercial maintenance prevents most of these calls.
Rooftop unit repair
Rooftop package units hold the compressor, coils, blower and controls in one cabinet, which makes them quick to diagnose once we are on the roof. Common failures are broken or slipping blower belts, failed capacitors and contactors, condenser fan motors, clogged filters and coils, economizer faults and refrigerant leaks. We check the safeties and controls, then each component in turn, and repair what failed. If a unit is near the end of its life, we tell you and price a replacement alongside the repair.
Restaurants that cannot keep the dining room cool
A dining room that will not stay cool on a busy night is often a system that cannot keep up rather than one that has failed: dirty coils, a slipping belt, low refrigerant, or kitchen exhaust pulling hot air into the dining room because make-up air is short. We check the unit's capacity against the load, clean what is choking it, repair failed parts, and look at the balance between kitchen exhaust and make-up air. Where the space has simply outgrown the equipment, we say so.
Office split systems
Offices and small commercial spaces often run split systems with indoor air handlers above ceilings or in closets. The failures look like home systems at a larger scale: clogged condensate lines leaking into ceiling tiles, frozen coils, failed blower motors, and thermostats and controls that fight each other across zones. We find the fault, protect ceilings and equipment from water, and repair it, scheduling around office hours when the repair can wait. Server closets and other rooms that must stay cool get priority.
Getting the business cooling again
Belts, capacitors, contactors, filters and drain clears are usually fixed on the first visit. Compressor, coil and control replacements take longer, and when a part has to be ordered, we tell you the timeline before you decide.
Restarting businesses after an outage
During Hurricane Ida's long outage, a collapsed tower darkened New Orleans and the east bank of Jefferson Parish while heat index values reached 106. When power returned, businesses restarted their rooftop units at once, and the ones with weak capacitors, slipping belts or surge-damaged controls failed together. A post-outage restart is the time to have commercial units checked, before a full dining room or office tests them on the first hot afternoon.
How a commercial repair call runs
- Talk to the managerWhat failed, when, and what the space needs today.
- Check controls and safetiesThermostats, economizer and safety switches.
- Test the componentsElectrical parts, belts, motors, coils and charge.
- RepairQuote first, then the fix.
- Run and confirmSupply air and space temperature checked.
What decides the cost of a commercial repair
Commercial repairs are quoted on site, so we do not publish a figure. These are the main drivers.
- Type of failure. Belts and capacitors cost far less than compressors.
- Unit size and type. Larger rooftop units take larger parts.
- Roof access. Hatches, ladders and lifts affect time on site.
- Refrigerant work. Leak repairs and recharges add parts and time.
- Controls and economizers. Boards and actuators vary widely in price.
