AC repair in Plano

Plano quotes vary by job, so start from HomeGuide's national figures, which put an AC repair at $150 to $650 on average, with technicians at $75 to $150 an hour; a big out-of-warranty repair can reach $650 to $2,500 or more. Replacing a standard-efficiency central system runs $5,000 to $8,300.

Those ranges matter most in late summer. ERCOT, which runs most of the Texas grid, set an all-time peak demand record of 91,089 megawatts on July 22, 2026, ahead of the 85,508 MW mark from August 10, 2023 (both unofficial until final settlement). Ask about a spring tune-up slot rather than waiting for a July breakdown. Full cost tables are on the Texas HVAC guide.

Plano's handout, revised January 2020, groups mechanical and irrigation contractors and lists a $100 annual registration. Since September 1, 2021, state law has said Texas cities may not charge TDLR-licensed HVAC contractors registration fees, although they can still collect building permit fees. Ask Building Inspections (972-941-7140) what a licensed AC company must file today; the handout itself says it is informational only.

Texas rules also make HVAC licensees give each city a list of the agents allowed to pull permits under their license. When a crew arrives, ask whose license the Plano permit was pulled under and check that the name matches the contractor on your invoice.

Plano AC replacement rules that come from federal law

Texas falls in the federal Southeast efficiency region. A split-system central air conditioner installed on or after January 1, 2023 must reach at least 14.3 SEER2 below 45,000 Btu/h, or 13.8 SEER2 at 45,000 Btu/h and above. New residential systems are also limited to refrigerants with a global warming potential of 700 or less from January 1, 2025, unless every part was made or imported before that date. Ask which refrigerant a quoted system uses and whether its parts predate the rule.

Anyone who installs, repairs or maintains heating and cooling equipment for pay in Texas needs a TDLR license, and an HVAC company must employ a licensed contractor at each permanent office. The license is valid statewide, which is why a separate city license is not required.

1. Read the license number on the estimate. It shows the class and endorsement, in the form TACL/A/000000/C.
2. Search it on TDLR's License Data Search, which lists both air conditioning contractors and A/C technicians.
3. Match the class to the job. Class B covers cooling up to 25 tons and heating up to 1.5 million BTU per hour; Class A covers any size.
4. Ask for proof of liability insurance. Class A contractors carry at least $300,000 per occurrence, Class B at least $100,000.

The technician on your roof may be a registered technician working under the contractor's supervision. Registered technicians cannot advertise HVAC services on their own.

Oncor lists Plano among the cities it serves, and in its area residents pick a retail provider for their plan. Oncor runs its efficiency programs through independent service providers listed on its Take A Load Off Texas site when programs are open, and Oncor is not a party to your contract with that provider. A contractor who says a rebate is guaranteed should be able to show the program listing. The CoServ co-op serves parts of Collin County, so check your bill first.

If the repair involves a condensate line or a shared closet with the water heater, compare Plano plumbers too. Neighbors north of the city line can see AC repair in Allen, and the Plano city page covers permits and utilities in one place.
