5-star rating on GoogleRooftop Unit Replacement in New Orleans, LA
Commercial rooftop unit replacement New Orleans buildings need is a packaged unit that is done, not a condenser swapped in an afternoon. A rotten cabinet, a second compressor failure, or a coil that has been eating salt air can make another repair a poor spend. The new unit still has to match the curb or use an adapter, the crane has to reach the roof, and the duct, the power, and the drain have to land. New Orleans Mechanical Pros is veteran-owned. We plan that changeout before the unit is ordered. Call New Orleans Mechanical Pros at (504) 826-3775 to discuss commercial rooftop unit replacement in New Orleans. Say the cross street when you call so the crane question starts with the building, not a guess.
Commercial Rooftop HVAC Replacement In New Orleans
RTU replacement New Orleans LA jobs are restaurants, small hotels, offices, and retail bays whose packaged unit will not hold the room. Repeated compressor failures, a cabinet you can see through, and a repair quote that is most of a new unit are the usual reasons. Ordering the same tonnage off the old nameplate skips the building. Humidity, a kitchen hood, and a longer cooling season change the load. The repair path, when the cabinet is still sound, is commercial HVAC repair.
Types Of Commercial Rooftop Units We Replace
Gas/electric, cooling-only, and heat-pump rooftops are different machines. The name on the door does not pick the replacement.
Commercial Packaged Rooftop AC Units
A packaged cooling unit carries the compressors, the condenser, and the evaporator in one cabinet, and it has to move the air the duct was built for. A house condenser is not this job. Home changeouts are AC replacement.
Gas/Electric Rooftop HVAC Units
Gas/electric units cool and heat in the same box. The gas piping, the venting, and the heat exchanger have to be part of the look. A cracked exchanger is a reason to shut the heat down, not to keep firing it. If you smell gas, leave and call the utility from outside.
Commercial Rooftop Heat Pumps
A rooftop heat pump heats with the reversing valve instead of a gas furnace. The electrical service and the controls have to match that sequence. Mild winters help. They do not size the unit. Auxiliary heat, if the building has it, gets checked at startup.
Carrier Commercial Rooftop Unit Replacement
Carrier commercial RTU replacement New Orleans owners ask about starts with the model, the serial, the curb dimensions, the voltage, and how the supply and return sit. A new Carrier unit is an option when it fits. It is not a requirement. Another manufacturer can go on that roof if the curb, the power, the duct, and the capacity work, often with an adapter. We do not claim to be an authorized Carrier dealer or a factory-certified Carrier contractor.
Trane, YORK, Lennox, And Other Commercial RTUs
Trane, YORK, Lennox, Daikin, and the rest get the same test: curb, electrical, duct, ventilation, and whether the tonnage belongs on this building. A logo match is not a load calculation. We do not claim a dealer badge for any of them.
Emergency Commercial RTU Replacement In New Orleans
A search for emergency commercial RTU replacement New Orleans is a hotel, a restaurant, a store, an office, or a medical suite with no cooling and a unit that will not be repaired. We still check whether a repair can carry the building while a replacement is ordered. A crane date and a unit on a truck are not the same thing, and we do not promise either is free this week. The office is open 24 hours a day, 7 days a week. You get a window before a truck is sent. That is not a promised arrival time. Call (504) 826-3775 and say which unit is down.
Signs Your Commercial Rooftop Unit Needs Replacement
Frequent compressor failures, repair bills that keep climbing, a unit that trips every afternoon, cooling that never catches up, a cabinet or coil you can poke a finger through, refrigerant leaks, a damaged heat exchanger, parts the supplier cannot get, storm damage that opened the cabinet, or a building that outgrew the unit. Age is a clue. A 15-year-old rooftop that still cools and has parts is not automatically scrap. A younger unit with a failed heat exchanger might be.
Commercial Rooftop Unit Crane Lifts And Rigging
Many changeouts need a crane because the cabinet will not come down a stair. Weight, roof height, where the truck can sit, overhead lines, and the weather decide the lift. A CBD street and a tight French Quarter block are different from a Metairie pad with a side lot. The lift plan belongs to the qualified rigger and the crane operator. We coordinate the day with the building. We do not invent the rigging. A small unit on a low roof is sometimes a different set. Do not assume every job is a crane, and do not assume a downtown roof is a roll-up.
Roof Curb, Ductwork, And Electrical Requirements
Rooftop HVAC replacement New Orleans jobs fail at the curb when the new footprint does not match the old one. An adapter, a new curb, or a transition in the supply and return duct is normal, not a surprise at the crane. Flashing and the roof membrane are part of keeping water out after the unit is set. Voltage, phase, the breaker, and the disconnect have to match the nameplate. Gas piping applies only if the new unit heats with gas. The condensate has to leave the roof. A thermostat can be landed. We do not claim to program every building-automation brand. Order the unit after those measurements, not before.
Commercial Rooftop Unit Replacement For New Orleans Businesses
Commercial roof AC replacement New Orleans properties use is hotels, restaurants, retail, offices, medical and dental rooms, schools, warehouses, and multi-tenant buildings. A restaurant hood and a weekday office do not share a ventilation load. Occupancy and the hours the roof can be open pick the day. The written list of what is on that roof is also how commercial HVAC maintenance gets booked later. A chiller plant is a different machine, on chiller repair.
Our Commercial Rooftop Unit Replacement Process
Step 1: Inspect The Existing Rooftop Equipment
We read the model, the serial, the voltage, and what has already failed. Photos of the curb and the duct openings save a second trip. A nameplate that is gone gets measured, not guessed.
Step 2: Determine The Correct Replacement Equipment
Tonnage comes from the building, the glass, the people, and the ventilation, not from copying the old sticker. An oversized unit short-cycles and leaves the air wet. An undersized one will not hold a lunch rush. Manufacturer options stay open.
Step 3: Plan Crane, Roof Curb, And Mechanical Work
Crane day, curb or adapter, duct transitions, electrical, gas if any, and the hours the tenant can be without cooling go in the proposal. Street access in the CBD is planned then, not the morning of the lift.
Step 4: Remove And Install The Rooftop Unit
The old unit comes off, the opening gets covered until the new one is set, and the duct, the power, the drain, and the gas if it applies get connected. We do not leave an open curb overnight without a cover the building has agreed to.
Step 5: Complete Startup And Commissioning
Startup is cooling, heat if the unit has it, airflow, the economizer, the safeties, and the control that is supposed to run it. A disconnected economizer is not a finished job. The exact tests follow that model.
Why Choose New Orleans Mechanical Pros For Rooftop Unit Replacement?
Veteran-Owned Commercial HVAC Company
We are veteran-owned. The company was formed in 2022 and publishes 17 years of hands-on trade experience. That is not 25 years under this name.
Knowledge Of Commercial Rooftop Equipment
Packaged cooling, gas/electric, and heat-pump rooftops, plus the curb, the duct, and the electrical that have to match. A residential changeout checklist misses the crane and the economizer.
Understanding New Orleans Rooftop Conditions
Humidity, rain on an open curb, and corrosion on coils near the lake are why these cabinets fail here. Older downtown roofs are hard to reach. A storm-opened cabinet is a replacement talk only after someone has seen it. We do not price one from a photo of standing water.
Complete Rooftop Replacement Planning
The proposal should name the unit, the curb plan, the crane, the electrical, and what is not included. Commissioning is part of the job, not a courtesy visit. If a repair will carry the season, we say that.

Frequently Asked Questions About Rooftop Unit Replacement In New Orleans
How much does commercial rooftop unit replacement cost in New Orleans?
There is no flat price. Tonnage, gas heat, a crane, a curb adapter, duct changes, and electrical work all move it. You get a written proposal after the roof and the nameplate are seen. We do not publish a per-ton rate.
How long does it take to replace a commercial rooftop HVAC unit?
The crane day is not the lead time. The unit, the curb measurement, and street access all have to be known first. We will not name a week before that. You should hear what is waiting on equipment and what is waiting on the lift.
Can a new rooftop unit use the existing roof curb?
Sometimes, when the footprint and the duct openings match. Often they do not, and the job needs an adapter or a new curb. Measure that before the unit is ordered. A crane should not arrive to a cabinet that will not sit.
Do commercial rooftop unit replacements require a crane?
Many do, because the cabinet will not use the stairs. A small unit on a low roof may not. Downtown streets and overhead lines change the lift. The rigging plan comes from the crane crew. We do not assume every roof is a crane.
How do you determine the correct tonnage for a commercial RTU?
From the building load, the ventilation, and how the space is used, not from the old nameplate. A restaurant and an office of the same size are not the same tonnage. Oversized equipment short-cycles in this humidity. We do not size it by phone.
Can a Carrier rooftop unit be replaced with another manufacturer?
Yes, when the curb, the power, the duct, and the capacity can be made to work. An adapter is common. Staying with Carrier is also fine. We are not an authorized Carrier dealer. The building decides, not the logo.
Do commercial rooftop HVAC replacements require permits?
Often yes, when the equipment, the electrical, or the gas piping changes. The parish and the scope decide. We confirm that for the job instead of promising every roof is exempt. An inspection, if required, is part of the schedule.
Should I repair or replace my commercial rooftop unit?
Repair one failed part when the cabinet, the coil, and the heat exchanger are sound. Replace when compressors keep failing, the cabinet is rotten, parts are gone, or the exchanger is cracked. Age is not the rule.
