AC repair in Denton

Denton Municipal Electric is a public power utility. Under PUC rules its customers can choose a retail electric provider only if the city has opted in to competition. Oncor lists Denton among its cities too, and Oncor's efficiency programs run through independent providers when open, so whether they reach you depends on whose wires serve your house. Check your bill.

The county's emergency managers publish extreme heat guidance, and ERCOT hit an all-time peak of 91,089 megawatts on July 22, 2026 (unofficial until settlement). Book maintenance in spring rather than in a July heat wave.

HomeGuide's national averages: AC repair $150 to $650, technicians $75 to $150 an hour, large out-of-warranty repairs $650 to $2,500 or more, and a standard-efficiency central AC replacement $5,000 to $8,300. They are not Denton prices. Our HVAC guide covers the details.

A split-system central AC installed in Texas on or after January 1, 2023 must reach 14.3 SEER2 under 45,000 Btu/h or 13.8 SEER2 above it. New residential systems are limited to refrigerants with a global warming potential of 700 or less from January 1, 2025, except systems whose parts were all made or imported before then.

Look up the company and technician on TDLR's License Data Search. The license number shows class and endorsement, for example TACL/A/000000/C; Class B covers home-sized systems up to 25 tons, Class A any size. Class B contractors carry at least $100,000 of liability coverage per occurrence. Helpers must be TDLR-registered technicians, and those under 18 need direct supervision.

The license is statewide, and since September 1, 2021 cities can't charge licensed contractors registration fees, only permit fees. Ask the City of Denton what permit a replacement needs, and get the permit number from the contractor. A new circuit is a job for Denton electricians; compare AC repair in Little Elm, and see the Denton page for utility notes.

• Efficiency. For a heat pump, ask for at least 14.3 SEER2 and 7.5 HSPF2, the federal minimum for split systems made since January 1, 2023.
• Refrigerant and build date. Ask which refrigerant the unit uses and when its parts were made, since that decides whether the 2025 limit applies.
• The diagnosis. Texas rules bar HVAC licensees from misrepresenting the need for service or making false statements to win a contract. Get the failed part named in writing.
• The permit. Licensees must give cities a list of agents allowed to pull permits under their license, so ask the contractor to pull the permit in its name.

Texas's HVAC licensing law doesn't apply to work in a building you solely own as your home, but check the city's permit rules before relying on that.
