AC repair in Mesquite

HomeGuide's national figures (2025) give a yardstick for Mesquite quotes:

• AC repair: $150 to $650 on average, with technicians at $75 to $150 an hour
• Large out-of-warranty repairs: $650 to $2,500 or more
• Tune-up: $70 to $200
• Standard-efficiency central AC replacement: $5,000 to $8,300

ERCOT set an all-time peak demand record of 91,089 megawatts on July 22, 2026, unofficial until final settlement. A tune-up booked before summer gets the unit checked ahead of peak demand. The Texas HVAC guide covers costs by job.

Because Mesquite's 75149 ZIP is in Oncor's delivery area, Oncor's energy efficiency programs are the ones to ask about. When they're open, Oncor lists participating service providers on its Take A Load Off Texas site; those providers are third parties, and Oncor isn't part of your contract with them. Ask any Mesquite contractor quoting an incentive which program it is and whether it's open now.

Across the line in Garland, city-owned Garland Power & Light serves about 85% of residents, so check that city's page for its own setup.

Efficiency minimums for a Mesquite replacement

Texas is in the federal Southeast efficiency region, so a split-system central AC installed since January 1, 2023 must be at least 14.3 SEER2 below 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, though systems whose parts were all made before then have no installation deadline.

1. TDLR license: search TDLR's License Data Search under Air Conditioning Contractors. The license number reads like TACL/A/000000/C, with the class and endorsement in it. Class A covers any size; Class B tops out at 25 tons of cooling.
2. Technician: the person at your door should be a registered or certified technician working under that contractor.
3. Insurance: Class A contractors carry at least $300,000 per occurrence; Class B at least $100,000.
4. Mesquite permit: the city requires every permit applicant to register a professional license in its Citizen Self Service portal with a copy of the state license. Since September 1, 2021, Texas cities can't charge TDLR-licensed HVAC contractors a registration fee, but they can still charge permit fees.

Texas rules bar HVAC licensees from misrepresenting the need for a repair. If a second opinion would help, get one before agreeing to a replacement. Back to the Mesquite local services page.
