AC repair in Nederland, Texas
Nederland spells out which jobs need a permit, and an air conditioner replacement is on the list.
What Nederland requires
The city's Inspection Department publishes a list of work that needs a permit. Air conditioning replacements appear on it by name, along with trade work in HVAC, electrical and plumbing. The same department carries out mechanical, gas and electrical inspections.
In practice that means a straight swap of an outdoor unit still goes through the city. Ask the contractor to confirm they will pull the permit before the old unit comes out.

Reaching the department
The Inspection Department page lists its phone as (409) 723-1502. When this page was written, the city was inviting contractors to register on a new online permit system called GovWell. Contractors who have worked in Nederland before will know the current process.
Repair calls in Nederland
Most service calls here look like the ones in Beaumont: tired capacitors, clogged drains and coils packed with debris. The repair page explains each one. A repair that does not replace equipment usually does not trigger the replacement permit, but the contractor decides how the city's list applies to a given job.

Electric utility
Entergy Texas includes Jefferson County in its service area. Its tune-up program page showed enrollment closed when this page was written.

Say what the system is doing and how old it is, if you know. The person you reach works for an independent contractor in Southeast Texas, not for this website.
