TDLR license and technicians

Anyone installing, repairing or maintaining heating or air conditioning in Texas needs a TDLR license, and every company must employ a licensed contractor at each permanent office. Getting the license takes 48 months of supervised experience within 72 months, or 36 within 48 for a certified technician of a year, plus an exam. Helpers must be registered technicians working under the contractor, and Texas has two technician levels, registered and certified. Search names on TDLR's License Data Search.

Sherman registration and permits

Sherman requires all contractors to register, and state-licensed mechanical contractors do it through the Self Service Portal. The city adopted the 2021 ICC codes on February 5, 2024, and permits are applied for online. Ask Development Services (903-892-7229) whether your replacement needs a permit, and if it does, get the number and follow the inspection.

New system rules

A new split-system AC in Texas must be at least 14.3 SEER2 below 45,000 Btu/h or 13.8 SEER2 above it. From January 1, 2025, new residential systems use refrigerants with a global warming potential of 700 or less, unless all parts were made or imported before then.

Oncor lists Sherman among the cities it serves and points new customers to PowerToChoose.org to pick a retail provider; some edge areas may be on an electric co-op, so check your ZIP there. Oncor's efficiency programs run through independent providers on its Take A Load Off Texas site when open, and Oncor is not part of your contract with them. ERCOT set an unofficial peak record of 91,089 megawatts on July 22, 2026, which shows how hard summer runs the grid; book a spring tune-up before the rush.

Texas rules bar HVAC licensees from misrepresenting the need for service. A second opinion on a full replacement is reasonable. Bigger systems can need electrical work from electricians in Sherman. Compare AC repair in McKinney, and see the Sherman services guide for permits.
