Replacing a worn central AC in a 1980s Des Allemands brick home

Cooling trouble in a humid Des Allemands home

The homeowner called when the central air conditioner could no longer keep the house comfortable through spring cooling. The outdoor condenser showed wear, and the indoor coil was part of the same aging system. Because the home is a one-story brick house from the 1980s, our technicians also planned around the original ductwork and the equipment access built into the home.

Our team inspected the existing system before discussing the replacement. The goal was not to change the home's layout. It was to replace the worn outdoor section and match the indoor coil to the existing duct system, while keeping the work appropriate for a Des Allemands home served by Entergy Louisiana and covered by the local inspection process.

The condenser and indoor coil needed to work as a pair

Inspection showed that the worn condenser was no longer a sensible repair candidate for this job. The indoor coil also needed replacement so the new outdoor equipment would have a proper match. Our technicians checked the existing connections, the coil cabinet, the access route, and the original ductwork before selecting the replacement equipment.

The original duct system remained serviceable for the replacement. That mattered in this 1980s brick home, where the practical solution was to preserve the established supply and return paths rather than change the home's arrangement. We also accounted for the St. Charles Parish portion of Des Allemands, where the parish Department of Planning and Zoning handles the local code office process.

From inspection to a matched cooling system

1. Inspect the existing system

   We documented the homeowner's cooling concern, examined the worn condenser and indoor coil, and checked the original ductwork and equipment access before building the replacement plan.

2. Confirm the equipment match

   Our technicians selected a matching outdoor condenser and indoor coil for the existing central AC setup. We reviewed the connections and cabinet dimensions so the new equipment would fit the home's established arrangement.

3. Remove the worn equipment

   We disconnected and removed the old condenser and indoor coil carefully, protecting the nearby brick exterior, indoor finish surfaces, and the duct connections that were staying in place.

4. Set the new condenser and coil

   The new outdoor condenser was placed at the existing equipment location, and the matching indoor coil was installed at the indoor cabinet. We connected the system to the original ductwork.

5. Test and complete inspection

   We checked the electrical connections, refrigerant circuit, airflow, condensate path, and cooling operation. After the system checks, the job proceeded through the applicable St. Charles Parish inspection process.

Cooling returned without changing the home's layout

The replacement gave the household a matched central AC system using the original ductwork. The outdoor condenser and indoor coil now operate as one equipment pair, with the duct connections kept in their existing arrangement.

Our final checks confirmed cooling operation, airflow through the established supply and return paths, proper electrical connections, and a clear condensate route. The work was completed in one day, plus the inspection, so the homeowner had a finished cooling system without a broader change to the 1980s brick home.

What made this a major replacement

This job cost more than a repair because it involved two matched central AC components, careful removal, installation on the original ductwork, system testing, and the local inspection process.
