AC repair in Carrollton

The state's Power to Choose feed lists only Oncor as the delivery company for Carrollton's 75006 ZIP code, and residents buy power from a retail provider they choose. A ZIP can cross city lines, so enter your own ZIP on Power to Choose when you compare plans.

When Oncor's energy efficiency programs are open, they run through independent service providers listed on its Take A Load Off Texas site. Oncor isn't a party to your contract with that provider, so a promised incentive should be in writing from the provider itself. If a Carrollton contractor quotes a rebate, ask which program it comes from and whether it's open now.

A Texas summer pushes the grid hard: ERCOT set an all-time peak demand record of 91,089 megawatts on July 22, 2026, topping the 85,508 MW record of August 10, 2023 (records are unofficial until final settlement).

HomeGuide's national figures give a baseline for Carrollton bids: $150 to $650 for an average repair, technicians at $75 to $150 an hour, and $650 to $2,500 or more for a large out-of-warranty repair. Replacing a standard-efficiency central system runs $5,000 to $8,300.

Efficiency and refrigerant rules for a new Carrollton system

Texas is in the federal Southeast region, so a split-system central AC installed since January 1, 2023 must be at least 14.3 SEER2 under 45,000 Btu/h, or 13.8 SEER2 at 45,000 Btu/h and up. New residential systems are also limited to refrigerants with a global warming potential of 700 or less from January 1, 2025, with a carve-out for systems whose parts were made or imported earlier. Ask any bid which applies. The full price table is on the Texas HVAC guide.

Anyone installing or repairing AC or heating for hire in Texas needs a TDLR air conditioning and refrigeration contractor license, and the company must employ a licensed contractor at each permanent location. The license is valid statewide, so a contractor doesn't need a separate Carrollton license. Search the name or number on TDLR's License Data Search, which lists contractors and AC technicians.

• Class. A Class B license covers cooling systems up to 25 tons; Class A has no size limit. The number shows class and endorsement, as in TACL/A/000000/C.
• Insurance. Class B contractors carry at least $100,000 per occurrence of general liability; Class A at least $300,000.
• The tech at your door. Helpers must be TDLR-registered technicians working under the contractor.

Carrollton permits and city fees

Since September 1, 2021, Occupations Code 1302.304 has barred Texas cities from charging TDLR-licensed HVAC contractors registration fees, though they may still charge building permit fees. Ask the contractor whether a replacement needs a Carrollton permit, and get the permit number. Contractors must give the city a list of agents allowed to pull permits under their license.

A new heat pump or a bigger condenser may need a new circuit, which is a job for Carrollton electricians. For power, tax and court details see the Carrollton hub, and for the next city west, AC repair in Lewisville.
