Do I need a TDLR license to start an HVAC business in Texas?

Air conditioning and refrigeration contracting in Texas is regulated by TDLR. What your business needs depends on the work performed and how it is structured. Confirm directly with TDLR.

Is EPA certification the same as a Texas license?

No. They are separate requirements from separate authorities. Federal refrigerant handling certification does not replace state contractor licensing, and vice versa.

Does Texas require workers' compensation?

Texas treats workers' compensation differently from most states, and what applies depends on your specific circumstances and contracts. Confirm with the Texas Division of Workers' Compensation and your insurance agent before hiring.

Starting an HVAC Business in Texas

Texas licenses air conditioning and refrigeration contractors at the state level — and that is only one of the credentials the work involves.

Last updated August 27, 2026

Texas is a strong HVAC market and a clear example of how the requirements stack. Air conditioning and refrigeration contractor licensing runs through a state agency, refrigerant handling is federal, the business entity is a separate registration with the state, and the city or county where the job sits still controls permitting and inspection. Different layers, different authorities, and none of them substitutes for another.

Use this page to understand the shape of what is ahead, then verify the specifics with the official sources listed below. Rules and fees change.

State licensing sits with TDLR

Air conditioning and refrigeration contractor licensing in Texas is administered by the Texas Department of Licensing and Regulation (TDLR). Qualifications, license classes, endorsements, insurance requirements tied to the license, and renewals are all defined there.

TDLR is the authority for what your specific situation requires. Confirm before you commit to an application path.

Refrigerant handling is a separate federal obligation

Federal refrigerant requirements come from the EPA's Section 608 program and exist independently of any Texas license. In general, technicians who maintain, service, repair, or dispose of equipment in ways that could release refrigerant must be certified, and the certification type depends on the equipment involved. Purchases of certain refrigerants are also restricted, with specific rules for certified technicians and their employers.

Holding a Texas contractor license does not satisfy the federal requirement, and Section 608 certification does not substitute for state licensing. Confirm the current federal rules with the EPA and the state requirements with TDLR — both change.

The company itself has to be set up

Forming your entity, registering with the Texas Secretary of State where required, obtaining an EIN, setting up state tax accounts as applicable, and opening business banking are separate from licensure. Keep the legal name identical across all of them.

Texas handles workers' compensation differently

Texas is unusual in how it treats workers' compensation coverage for private employers, and the rules that apply to a specific business depend on the work, the customers, and the contracts involved. Do not assume what applies in another state applies here. Confirm with the Texas Department of Insurance, Division of Workers' Compensation, and with an agent, before you hire.

Permits and inspections are decided locally

Whether a changeout, a new system, or the gas and electrical work tied to it requires a permit — and who is allowed to pull it — is set by the city or county where the job is located, not by the state license. Austin, Houston, San Antonio, Dallas, and Fort Worth are common examples of jurisdictions with their own permitting expectations, and they are examples only, not a complete list.

Build permit time, inspection scheduling, and the possibility of a re-inspection into how you quote. Verify with the permitting authority for the address you're working at.

Seasonality is the business risk

Texas summers concentrate revenue into a handful of brutal months. Companies that price against peak-season volume and staff for it without planning the rest of the year end up cash-poor in the shoulder months. Equipment cash flow makes it sharper: on replacement work you often owe the supply house before the customer or their lender funds the job. Build the year, not the busy weeks.

Licensing is the entry fee, not the business

Getting licensed lets you contract. Pricing, hiring, collections, job costing, and the systems that let you take a day off are a separate body of work — the part CEO in Boots turns into a guided Blueprint built around your trade and your state.
