Air conditioner replacement and installation for New Orleans homes

When a system is past its useful life, the right replacement is sized for your house and its humidity, matched indoors and out, and installed with a permit. We quote options in writing and install most changeouts in one day.

The short answer

An AC replacement in New Orleans typically means a matched outdoor unit and indoor coil, installed on existing ductwork in one working day with a city mechanical permit. Sizing should come from a load calculation, not the old unit's label, because an oversized system here cools fast, short cycles and leaves the house humid.

Installation

Repair or replace: how we help you decide

Updated September 2026

We do not recommend replacement on age alone. A 14 year old system with a failed capacitor gets a capacitor. The same system with a failed compressor, a leaking coil or an obsolete refrigerant is a different conversation, and we lay out both options with the costs side by side.

When replacement is the right call, sizing matters most. We measure the house rather than copying the old tonnage, because many older systems were oversized.

Scope

Condenser only, coil and condenser, or full system.

Ductwork

Repair or replacement found during the job adds cost.

Condenser-Only Replacement

Replacing just the outdoor unit can make sense when the indoor coil and air handler are recent and compatible with the new unit's refrigerant. It costs less up front. The risk is a mismatch: an old coil paired with a new condenser can reduce efficiency and shorten the new unit's life, and manufacturers may limit warranty coverage on mismatched systems. We check the coil's age, refrigerant and model compatibility before offering this option, and we tell you plainly if the coil should be replaced too.

Matched System Replacement

A matched system replaces the outdoor unit and the indoor coil, and usually the air handler, as a certified combination. That is how efficiency ratings and warranties are designed to work. We replace or flush the line set, install a new drain pan and float switch, pull a mechanical permit, charge by weight, and set airflow for humidity removal. A standard changeout on existing ductwork is usually completed in one working day, and the city inspection is scheduled before we leave.

Two-Stage and Variable-Speed Options

Single-stage systems run at full output or not at all. Two-stage and variable-speed systems run at lower output most of the day, which means longer, quieter runs, steadier temperatures and better moisture removal, a real advantage in a humid house. They cost more up front. We explain where the upgrade is worth paying for and where a well-sized single-stage system will do the job. Many homes are well served by a two-stage unit, which captures most of the humidity benefit at a lower price than a variable-speed system.

The systems coming due now

Much of Lakeview and the Lower Ninth Ward was rebuilt after 2005 with raised homes and new mechanical systems, and those systems are now 10 to 20 years old. We are replacing a lot of them, often on stands that already meet flood elevation. Installed replacement costs in this metro run slightly below the national average, mainly because labor rates here are a little lower.

Brands we service and install

We repair and install Trane, Carrier, Lennox, Goodman, Rheem, Ruud and the other major lines, plus Mitsubishi Electric ductless.
