Short answer

A new ductless mini-split in Texas is ACR work — TDLR doesn't exempt mini-splits from air conditioning licensing — and it adds a new electrical circuit, so expect mechanical and electrical permitting from the city. The contractor needs a TDLR ACR license and any required city registration; a new circuit from the panel may also need a licensed electrical contractor.

The general picture

A mini-split is new equipment, not a replacement, so there's no like-for-like shortcut. In Texas, the equipment work requires a TDLR air conditioning and refrigeration license, and the city issues the mechanical permit — plus electrical permitting for the new circuit — under the codes it has adopted. The Dallas–Fort Worth cities we've checked also have contractor registration rules to meet before you pull permits. See the Texas city pages for verified local notes.

Typically needs a permit

Installing new indoor and outdoor units, running line sets, and adding the dedicated circuit. Cities differ on whether the electrical work is its own permit or attached to the mechanical permit.

Usually doesn't (general norm)

  • Servicing or cleaning an existing mini-split
  • Replacing a remote or wall controller

Common reasons mini-split install applications get bounced

Code-rooted patterns across Texas — not a city-specific rejection rate.

The inspection sequence

A typical order — the number of stops and exact sequence vary by jurisdiction and scope.

  1. 1Rough electrical inspection before walls are closed, when applicable
  2. 2Final inspection with the system installed and operating

Licensing — who can pull it

Mini-splits in Texas are installed by a TDLR-licensed air conditioning and refrigeration (ACR) contractor; TDLR doesn't exempt mini-split systems from ACR licensing. The ACR license covers the electrical connections supplying the equipment, but a new circuit from the panel may need a TDLR-licensed electrical contractor — confirm before you quote.

Frequently asked questions

Do I need an ACR license to install a mini-split in Texas?

Yes. TDLR's air conditioning and refrigeration licensing doesn't exempt mini-split systems.

Do I need an electrician for the mini-split circuit?

Texas exempts ACR licensees making the electrical connections that supply the equipment. Whether that covers a new branch circuit from the panel isn't spelled out in the exemption, so confirm with TDLR or the city before quoting.

Which permits will the city want?

Expect mechanical permitting for the equipment and electrical permitting for the new circuit. Cities differ on whether those are separate permits or one linked record.
