Commercial AC Repair New Orleans | Commercial HVAC Experts

Running a commercial building in New Orleans is already a full-time job. The last thing you need is an HVAC system that decides to quit on a Friday afternoon in July when the heat index is pushing 108°F and you've got a full house of customers, guests, or employees counting on you. That's the reality we deal with down here, and it's exactly why New Orleans Mechanical Pros was built the way it was — not as a residential shop that dabbles in commercial work, but as a dedicated commercial HVAC contractor with the equipment, the training, and the field experience to handle the systems that keep businesses running.

ASHRAE Standard 90.1 is the energy efficiency standard for commercial buildings — all New Orleans commercial HVAC installations must comply with its requirements for equipment sizing, controls, and insulation.

The Air Conditioning Contractors of America (ACCA) Quality Installation standard for commercial systems requires commissioning verification, including airflow measurement and refrigerant charge confirmation, before system handoff.

ENERGY STAR commercial building certification requires HVAC systems to perform in the top 25% of similar buildings nationally — a benchmark our commercial clients regularly achieve.

We are a Disabled Veteran-Owned commercial HVAC company with 17 years of mechanical industry experience and three years of deep roots serving businesses throughout Greater New Orleans. Our technicians are licensed, insured, and NATE-certified — trained specifically on the rooftop units, chillers, boilers, air handlers, and building automation systems that commercial buildings depend on. We handle everything from a single-tenant retail space to a multi-story hotel to a 200,000-square-foot distribution warehouse, and we treat every job with the same standard of professionalism and accountability that military service instilled in us.

Whether you need emergency commercial AC repair in New Orleans, a preventive maintenance agreement to protect your equipment investment, a full system replacement, or a new installation for a build-out, New Orleans Mechanical Pros is the commercial HVAC company in New Orleans that businesses call when the stakes are too high to gamble on the wrong contractor.

Why Businesses Choose New Orleans Mechanical Pros — A Trusted Commercial HVAC Company in New Orleans

There is no shortage of HVAC companies in the New Orleans area, but there is a significant shortage of contractors who truly understand the demands of commercial mechanical systems. Most residential-focused companies will take a commercial call, but they're often working outside their depth — misdiagnosing complex controls issues, underestimating refrigerant system requirements, or recommending equipment that isn't rated for the application. We've seen the aftermath of those decisions more times than we can count.

New Orleans Mechanical Pros was built from the ground up as a commercial HVAC contractor in New Orleans. Here is what that means in practice:

Disabled Veteran-Owned Business. Our ownership comes from a military background, and that shapes everything about how we operate — the discipline, the attention to detail, the zero-tolerance policy for cutting corners, and the commitment to doing what we said we'd do, when we said we'd do it. Businesses that have been burned by contractors who disappeared mid-job or padded invoices with unnecessary work tend to appreciate working with us.

17 Years of Commercial HVAC Experience. We have worked on every major commercial system type — rooftop package units from 3 tons to 50 tons, centrifugal and screw chillers, steam and hot water boilers, variable refrigerant flow systems, hydronic heating and cooling, building automation systems, and industrial process cooling. That depth of experience means we diagnose problems faster, source parts more efficiently, and avoid the costly trial-and-error that less experienced contractors put on your invoice.

Licensed, Insured, and Certified. Louisiana Contractor License #75402. Full commercial liability insurance. NATE-certified technicians. EPA Section 608 certified for all refrigerant classes. These aren't just credentials — they're the minimum standard for anyone working on your commercial mechanical systems, and we hold every one of them.

Fast Emergency Response. Commercial HVAC emergencies don't follow business hours. We offer 24/7 emergency response for commercial clients because a restaurant that can't cool its kitchen, a hotel that loses chilled water in August, or a medical facility with a failed air handler cannot wait until Monday morning.

Honest Recommendations, Not Upsells. We diagnose what's wrong, tell you exactly what it will cost to fix it, and give you our honest assessment of whether repair or replacement makes more financial sense for your situation. We don't manufacture urgency or recommend equipment you don't need.

Complete Commercial HVAC Services in New Orleans

Commercial AC Repair New Orleans

When a commercial air conditioning system fails, the cause is rarely simple. Commercial systems operate under sustained loads that residential equipment never sees — running 12 to 18 hours a day, six or seven days a week, in buildings with high occupancy, heavy kitchen heat loads, server room demands, or industrial process requirements. The failure modes are correspondingly complex.

Our commercial AC repair technicians are trained to diagnose and resolve the full spectrum of commercial cooling failures: compressor failures on rooftop units and split systems, refrigerant leaks at brazed joints and service valves, electrical failures in contactors, capacitors, and control boards, thermostat and building automation control issues, airflow restrictions from fouled coils and blocked ductwork, and economizer malfunctions that cause systems to bring in unconditioned outside air. We carry a fully stocked service van with commercial-grade parts for the most common system failures, which means we resolve most commercial AC problems in a single visit rather than leaving your building without cooling while we wait for parts.

Commercial HVAC Repair New Orleans

Beyond straight cooling, our commercial HVAC repair capabilities cover the full range of heating and ventilation systems that commercial buildings depend on. Air handlers with failed blower motors or cracked heat exchangers. Heat pumps with reversing valve failures. Split systems with refrigerant circuit issues. Package units with economizer, heating, and cooling section problems. HVAC controls and Variable Frequency Drives (VFDs) that are mistuned, faulted, or failed. We work on all of it, and we work on all the major brands — Trane, Carrier, York, Lennox, Daikin, Rheem, AAON, Mitsubishi, LG, Bryant, Goodman, American Standard, Bosch, Liebert, McQuay, and ClimateMaster.

Commercial HVAC Installation New Orleans

New construction, tenant build-outs, system upgrades, and equipment replacements all require a commercial HVAC contractor who understands how to properly size, design, and install systems for the specific demands of the space. Oversized equipment short-cycles and fails to dehumidify — a critical problem in New Orleans where outdoor humidity routinely exceeds 80%. Undersized equipment runs continuously, wears out prematurely, and never achieves comfort setpoints.

We perform proper load calculations using ACCA Manual N for commercial applications, select equipment that matches the building's actual thermal load, and install systems to manufacturer specifications with full commissioning and performance verification before we consider a job complete. We also handle energy-efficient system upgrades — replacing aging equipment with high-efficiency units that qualify for utility rebates and deliver measurable reductions in operating costs. Our mechanical contracting team manages large-scale commercial installations from design through commissioning.

Commercial HVAC Maintenance New Orleans

The single most cost-effective investment a commercial building owner or facility manager can make is a preventive maintenance agreement. The data on this is unambiguous: according to the U.S. Department of Energy's Operations and Maintenance Best Practices Guide, well-maintained commercial HVAC systems consume 15 to 30 percent less energy than neglected ones, and preventive maintenance reduces emergency repair costs by up to 40 percent.

Our commercial HVAC maintenance agreements include seasonal inspections and tune-ups, coil cleaning (condenser and evaporator), filter replacement and media upgrades, refrigerant level verification and leak checks, electrical connection tightening and component testing, belt and motor inspections, thermostat and controls calibration, and written service reports after every visit. We also flag equipment that is approaching end of useful life so you can budget for replacements proactively rather than being blindsided by an emergency replacement during peak season.

Specialized Commercial Mechanical Services

Rooftop Unit Repair New Orleans (RTU Repair)

Rooftop package units are the workhorse of commercial HVAC in New Orleans. They're on virtually every strip mall, restaurant, office building, and retail center in the metro area, and they take an extraordinary beating from the Gulf Coast climate — intense UV radiation, salt-laden air, hurricane-force winds, and the kind of sustained heat that pushes compressors to their limits for months at a time.

Our rooftop HVAC replacement and repair technicians are experienced with the full range of rooftop unit diagnostics and repairs: compressor replacement and refrigerant circuit repairs, economizer damper and actuator repairs, fan motor and belt replacements, condenser and evaporator coil cleaning and repair, electrical component replacement (contactors, capacitors, control boards, transformers), and controls and thermostat troubleshooting. We work safely on rooftops of all heights and configurations, and we carry the rigging equipment to handle large RTU replacements when repair is no longer economically viable.

Commercial Chiller Repair New Orleans

Chillers are the most complex and most expensive equipment in commercial HVAC. A failed chiller in a hotel, hospital, or large office building can affect hundreds of people simultaneously, and the cost of an unplanned chiller failure — in lost business, emergency repair premiums, and potential equipment damage — can easily reach six figures. That's why chiller maintenance and early intervention are so critical.

We service both water-cooled and air-cooled chillers, including centrifugal, screw, and scroll compressor types. For a full overview of our chiller capabilities, visit our dedicated chiller repair New Orleans page. Our chiller services include condenser and evaporator tube cleaning, refrigerant circuit diagnostics and recharge, compressor oil analysis and replacement, pump and motor inspection, controls and building automation integration, and cooling efficiency optimization. We also work with the ASHRAE Standard 147 guidelines for reducing refrigerant emissions during chiller service — an important compliance consideration for commercial building operators.

Boiler Repair New Orleans

While New Orleans winters are mild by national standards, commercial buildings — particularly hotels, hospitals, and historic properties — often rely on boilers for domestic hot water, hydronic heating, and steam-based systems. A failed boiler in a 200-room hotel means cold showers for every guest. A failed steam boiler in a hospital creates immediate patient care concerns.

Our boiler repair capabilities cover steam and hot water boilers, heat exchanger inspection and cleaning, pump and circulator repairs, safety control testing and replacement, combustion analysis and burner tuning, and complete commercial heating system troubleshooting. We are familiar with the older boiler systems found in New Orleans' historic commercial buildings, many of which have been in service for decades and require technicians who understand legacy equipment.

Commercial Mechanical Services New Orleans

Beyond HVAC equipment, commercial buildings depend on a range of mechanical systems that require the same level of expertise and care. New Orleans Mechanical Pros provides comprehensive commercial mechanical services including hydronic system design and repair, cooling tower maintenance and water treatment coordination, air handler repair and replacement, mechanical piping installation and repair, and building automation system (BAS) integration and troubleshooting. We work with major BAS platforms and can integrate new equipment into existing building automation infrastructure to maximize energy efficiency and operational visibility.

24/7 Emergency Commercial HVAC Repair New Orleans

Commercial HVAC emergencies are not inconveniences — they are business crises. A restaurant that loses kitchen ventilation during dinner service faces health code violations and forced closure. Our 24/7 emergency HVAC service is specifically designed for these high-stakes situations. A hotel that loses chilled water in August faces mass cancellations and reputational damage that can take months to repair. A medical facility with a failed air handler faces patient safety concerns that cannot wait for a next-day service call. A warehouse that loses climate control in a distribution center can face spoilage losses that dwarf the cost of any HVAC repair.

We maintain 24/7 emergency commercial HVAC response because we understand what's at stake. When you call our emergency line, you reach a live technician — not an answering service, not a callback queue. We dispatch immediately, arrive with a fully stocked service van, and work until the problem is resolved. Our emergency response time for commercial clients in Orleans, Jefferson, and St. Bernard parishes is typically under two hours.

The types of commercial HVAC emergencies we respond to most frequently include restaurant AC failures during service hours, hotel cooling loss affecting guest rooms and common areas, warehouse HVAC failures threatening temperature-sensitive inventory, medical facility air handler failures, industrial production downtime caused by process cooling failures, and office building HVAC outages affecting large numbers of employees.

Industries We Serve

Restaurant HVAC Repair New Orleans

Restaurants are among the most demanding commercial HVAC environments in existence. Commercial kitchens generate enormous heat loads from cooking equipment, and that heat must be exhausted efficiently while conditioned make-up air is supplied to maintain negative pressure and prevent smoke and odors from migrating into dining areas. At the same time, dining rooms must be maintained at comfortable temperatures despite the heat load from the kitchen, the body heat of a full house of diners, and the thermal load from lighting and equipment.

We understand restaurant HVAC from the kitchen to the dining room — exhaust hood systems, make-up air units, walk-in cooler and freezer support, commercial refrigeration, dining room comfort systems, and the complex balancing act of managing pressure relationships between kitchen and front-of-house. We also understand that restaurant HVAC problems almost always happen during service, which is why our emergency response for restaurant clients is a genuine priority.

Hotel HVAC Services New Orleans

Hotels present a unique combination of HVAC challenges: dozens or hundreds of individually controlled guest rooms, large common areas with variable occupancy, conference and banquet facilities with high instantaneous heat loads, commercial kitchens, laundry facilities, and the central plant equipment — chillers, boilers, cooling towers, and air handlers — that serves the entire property. A failure anywhere in that system affects guest experience immediately and directly.

We have extensive experience with hotel HVAC systems of all sizes, from boutique properties in the French Quarter to large convention hotels in the CBD. Our hotel HVAC services include guest room PTAC and fan coil unit repair and replacement, central chiller and boiler maintenance and repair, cooling tower service, common area and lobby air handling, conference room HVAC, and 24/7 emergency response for any system failure that affects guest comfort.

Warehouse HVAC Contractor New Orleans

Warehouses, distribution centers, and manufacturing facilities present HVAC challenges that most contractors simply aren't equipped to handle — large clear-span spaces with high ceilings, significant heat loads from equipment and occupancy, loading dock areas with frequent door openings, and in many cases, climate-controlled storage requirements with tight temperature and humidity tolerances.

We work with warehouse operators, distribution center managers, and manufacturing facility owners throughout the New Orleans metro area to design, install, and maintain HVAC systems that meet the specific requirements of their operations. Whether that means large rooftop HVAC units with destratification fans, spot cooling for equipment rooms, or precision climate control for pharmaceutical or food storage, we have the experience and equipment to deliver it.

Industrial HVAC Contractor New Orleans

Industrial facilities — refineries, processing plants, manufacturing operations, and heavy commercial buildings — require HVAC contractors who understand process cooling, equipment room thermal management, and the safety requirements of industrial environments. We work in industrial settings regularly, and our technicians are trained on the specific protocols and safety requirements that industrial clients demand.

Office Buildings, Healthcare, Retail, and Government Facilities

Multi-story office buildings, medical offices and clinics, retail centers, government facilities, schools, and churches all have distinct HVAC requirements driven by their occupancy patterns, equipment loads, and comfort standards. We serve all of these facility types throughout Greater New Orleans, providing repair, maintenance, and installation services tailored to the specific demands of each building type.

Common Commercial HVAC Problems We Solve

After 17 years of commercial HVAC work, we've seen every failure mode that commercial systems produce. The most common problems we're called to resolve include commercial AC not cooling (typically compressor failure, refrigerant loss, or severely fouled coils), RTU not working (electrical failures, economizer issues, or refrigerant circuit problems), chiller failure (compressor or refrigerant circuit issues, fouled heat exchangers, or controls failures), boiler malfunction (ignition failures, heat exchanger problems, or safety control trips), HVAC controls failure (building automation faults, sensor failures, or programming issues), high energy bills (indicating system inefficiency from fouled coils, refrigerant undercharge, or failing compressors), refrigerant leaks (at service valves, brazed joints, or coil penetrations), poor airflow (from failed fan motors, blocked filters, or duct leakage), electrical failures (contactor, capacitor, or control board failures), and uneven building temperatures (from zoning issues, duct imbalance, or equipment sizing problems).

Our Commercial HVAC Repair Process

Every commercial HVAC engagement follows a structured process designed to minimize your downtime and maximize the accuracy of our diagnosis and repair.

Step 1 — Comprehensive Building Assessment. We start by understanding your building, your systems, and your operational requirements. What equipment do you have? What are your comfort and temperature requirements? What is the history of the system? This context shapes everything that follows.

Step 2 — Advanced HVAC Diagnostics. We use professional diagnostic equipment — manifold gauges, refrigerant analyzers, combustion analyzers, thermal imaging cameras, and electrical testing equipment — to gather objective data on system performance. We don't guess; we measure.

Step 3 — Identify the Root Cause. Commercial HVAC failures almost always have a root cause that goes beyond the obvious symptom. A failed compressor may have been caused by refrigerant undercharge that went undetected for years. A controls failure may be masking a sensor drift problem. We identify the root cause so we're not just treating symptoms.

Step 4 — Transparent Repair Estimate. Before we touch anything, you get a written estimate with a clear breakdown of parts, labor, and timeline. No surprises. No scope creep. If we discover additional issues during the repair, we stop and discuss them with you before proceeding.

Step 5 — Professional Repairs. Our technicians perform repairs to manufacturer specifications using OEM or OEM-equivalent parts. We don't cut corners on commercial systems — the consequences of a failed repair in a commercial building are too significant.

Step 6 — Performance Testing. After every repair, we verify system performance against design specifications — supply air temperatures, static pressures, refrigerant subcooling and superheat, electrical amperage draws, and controls operation. We don't call a job complete until the numbers confirm the system is performing correctly.

Step 7 — Preventive Maintenance Recommendations. We provide a written report of our findings, including any items that should be addressed proactively before they become failures. This gives you the information you need to make informed maintenance decisions.

Why Preventative Maintenance Saves Businesses Money

The economics of commercial HVAC preventive maintenance are straightforward, and the evidence is overwhelming. The EPA's ENERGY STAR program for commercial buildings consistently documents that buildings with active preventive maintenance programs operate 15 to 25 percent more efficiently than comparable buildings without them. Over the life of a commercial HVAC system, that efficiency gap translates to tens of thousands of dollars in avoided energy costs.

Beyond energy savings, preventive maintenance delivers lower operating costs through early detection of developing problems before they become expensive failures, reduced downtime because planned maintenance is scheduled around your operations while emergency repairs happen at the worst possible time, longer equipment life because well-maintained systems routinely outlast neglected ones by five to ten years, better indoor comfort and air quality for employees and customers, improved energy efficiency through clean coils and properly charged refrigerant circuits, reduced emergency repair frequency and the premium labor rates that come with them, and warranty protection — most commercial equipment warranties require documented preventive maintenance to remain valid.

Our commercial HVAC maintenance agreements are structured around your specific equipment inventory and operational requirements. We offer monthly, quarterly, and semi-annual visit frequencies depending on your system complexity and criticality, and every visit is documented with a written service report that becomes part of your equipment maintenance record.

Why Businesses Trust New Orleans Mechanical Pros

17 Years of Commercial HVAC Experience

Seventeen years in commercial HVAC means we've worked through every equipment generation, every refrigerant transition, and every building type that the New Orleans market has to offer. We've repaired chillers in French Quarter hotels that have been running since the 1980s. We've installed new rooftop units on warehouse rooftops in Elmwood and Harvey. We've maintained the HVAC systems in medical offices in Metairie and government facilities in the CBD. That breadth of experience is what allows us to walk into an unfamiliar building and quickly understand what's there, what's wrong, and what it will take to fix it.

Disabled Veteran-Owned Commercial Mechanical Contractor

Military service teaches you things that no technical training program can replicate — the importance of doing the job right the first time, the discipline to follow procedures even when shortcuts are tempting, the accountability to own your mistakes and fix them, and the communication skills to keep clients informed throughout a project. These values are embedded in how New Orleans Mechanical Pros operates, and they're why our commercial clients tend to stay with us for years.

Local New Orleans Knowledge

Commercial HVAC in New Orleans is not the same as commercial HVAC in Dallas or Atlanta. The combination of extreme summer heat, persistent high humidity, salt air from the Gulf, hurricane season wind and water exposure, and the unique characteristics of New Orleans' commercial building stock — including a large inventory of historic buildings with unconventional mechanical systems — creates challenges that require local knowledge and experience to navigate effectively.

We understand how Gulf Coast humidity affects refrigerant system performance and dehumidification requirements. We know how salt air accelerates corrosion on rooftop equipment and what protective measures extend equipment life in coastal environments. We've worked through multiple hurricane seasons and understand how to assess and repair storm-related HVAC damage. And we know the quirks of New Orleans' historic commercial buildings — the cast-iron radiator systems, the gravity-fed ductwork, the unconventional equipment placements — that confound contractors who haven't worked in this market before.

Customer Success Stories

French Quarter Restaurant — Emergency AC Repair During Service

A 120-seat French Quarter restaurant called us at 6:45 p.m. on a Saturday — their dining room rooftop unit had failed and they had a full reservation book for the evening. Our technician was on-site within 90 minutes, diagnosed a failed compressor contactor, replaced it from stock, and had the system running before the first seating was significantly impacted. Total downtime: under two hours. The restaurant owner has been on a preventive maintenance agreement with us ever since.

CBD Hotel — Chiller Repair During Peak Season

A 180-room CBD hotel experienced a partial chiller failure in August, losing approximately 40 percent of their cooling capacity during one of the busiest weeks of the year. We dispatched a senior chiller technician within three hours, diagnosed a failed compressor unloader valve, sourced the part from our supplier network, and completed the repair within 24 hours. The hotel avoided guest relocations and the associated costs and reputational damage that would have followed a multi-day outage.

Elmwood Warehouse — Rooftop Unit Replacement

A 60,000-square-foot distribution warehouse in Elmwood had three aging rooftop units that were consuming excessive energy and requiring increasingly frequent repairs. We performed a comprehensive assessment, recommended replacement with three high-efficiency units, coordinated the crane lift and installation over a weekend to minimize operational disruption, and commissioned all three units before Monday morning. The facility's energy costs dropped by approximately 22 percent in the first full billing cycle after installation.

Metairie Office Building — HVAC Controls Upgrade

A four-story Metairie office building was experiencing chronic comfort complaints and high energy bills despite relatively new HVAC equipment. The problem turned out to be an outdated pneumatic controls system that was providing inaccurate zone temperature data and causing equipment to run inefficiently. We replaced the pneumatic controls with a modern digital building automation system, recalibrated all zone sensors, and implemented an energy management schedule. Energy costs dropped 18 percent, and tenant comfort complaints essentially disappeared.
