Texas HVAC Systems Listings

The listings assembled under Texas HVAC Authority cover licensed contractors, registered service providers, and equipment specialists operating within the Texas HVAC sector. Each entry reflects publicly available licensing data, regulatory standing, and geographic service coverage as recorded through Texas state agencies. This reference serves service seekers, facility managers, and industry professionals navigating a market shaped by the Texas Department of Licensing and Regulation (TDLR) and enforced under Texas Occupations Code Chapter 1302.

How to read an entry

Each listing in this directory follows a standardized field structure designed to convey operational scope, credential status, and service classification without editorial embellishment. The fields and their meanings:

1. Business name — The registered trade or legal entity name on file with TDLR or the Texas Secretary of State.
2. License number — The TDLR-issued HVAC Contractor license identifier. Technician-level entries may carry an EPA Section 608 certification reference instead of or alongside a TDLR number.
3. License classification — Texas HVAC licensing distinguishes between Class A (unlimited tonnage), Class B (up to 25 tons per system), and related subcategories. See Texas HVAC Licensing Requirements for classification boundaries.
4. Service geography — County-level or metro-area coverage, not individual ZIP codes. Statewide-licensed contractors with no declared geographic restriction are flagged accordingly.
5. System specializations — Equipment categories the contractor has documented experience servicing, such as central air conditioning, ductless mini-split systems, or variable refrigerant flow systems.
6. Permit and inspection posture — Whether the listed entity pulls permits directly, operates through a licensed qualifier, or exclusively performs maintenance-only work not subject to permit requirements under the Texas Local Government Code.
7. Last verified date — The calendar quarter in which the listing's TDLR status was last confirmed against the public license search portal.

Entries do not include pricing, availability, or performance ratings. Those elements are outside the scope of a regulatory reference directory.

What listings include and exclude

Included:

• HVAC contractors holding a current, active TDLR Class A or Class B license
• Registered HVAC technicians with documented EPA Section 608 certification for refrigerant handling
• Commercial HVAC specialists serving Texas facilities subject to the International Mechanical Code (IMC) as adopted by the Texas State Fire Marshal's Office
• Providers operating in metro markets, including Dallas–Fort Worth, Houston, San Antonio, and Austin
• Contractors with documented experience in residential HVAC systems and commercial HVAC systems

Excluded:

• Unlicensed handyman or general maintenance services that may perform incidental HVAC work
• Equipment-only suppliers, wholesalers, and distributors not providing installation or service
• Engineers or architects whose HVAC scope is limited to design and specification under a Professional Engineer (PE) license with no installation function
• Federal facility contractors operating exclusively under federal procurement vehicles, which fall outside TDLR jurisdiction
• Providers whose TDLR license has lapsed, been suspended, or been revoked — these are removed from active listings and flagged in a separate status log

Refrigerant-handling compliance is governed by EPA Section 608 of the Clean Air Act. Listings referencing refrigerant service are expected to carry documentation of certified technician status, though the directory does not independently verify EPA records. For Texas refrigerant regulation context, that page addresses current phasedown implications under the AIM Act.

Verification status

Listings are derived from TDLR's public license database, which is updated on a rolling basis. TDLR data reflects license status at the time of the most recent sync — not real-time status. The verification cycle for this directory targets quarterly refresh, meaning any license action taken by TDLR within the preceding 90 days may not yet be reflected.

Verification does not constitute endorsement. A listing appearing as "active" confirms only that the license number matched an active TDLR record at the time of last sync. It does not confirm:

• Current insurance coverage (TDLR requires proof of liability insurance at licensing but does not publish carrier data)
• Bond status beyond the initial TDLR filing requirement
• Compliance with local municipal permit requirements, which vary across the 254 Texas counties

For metro-specific verification detail in the Dallas–Fort Worth market, Dallas HVAC Authority maintains a focused directory of DFW-area contractors and cross-references municipal permit records from the City of Dallas Building Inspection division. That resource is particularly useful for projects subject to Dallas's local mechanical code amendments layered onto the base IMC adoption.

Users confirming contractor standing for a specific project should cross-reference directly with TDLR's public license search before proceeding.

Coverage gaps

The listings in this directory are not exhaustive. Known structural gaps include:

Rural and small-county markets — Texas counties with populations below 20,000 have fewer TDLR-licensed contractors relative to metro areas. Listings for these areas may reflect only 1 or 2 active providers per county, and service coverage often depends on contractors based in adjacent counties.

Specialty system categories — Geothermal HVAC systems and ground-source heat pump installations represent a small fraction of the Texas market, and fewer than 40 contractors statewide have documented geothermal installation experience in TDLR records. Listings in this category are sparse and may lag behind actual market capacity.

New construction HVAC — Contractors operating exclusively in new construction under a general contractor's permit pull may not carry an independent TDLR contractor license, creating a visibility gap for that segment.

Manufactured housing — HVAC systems in Texas manufactured homes are regulated under the Texas Department of Housing and Community Affairs (TDHCA) rather than TDLR, and TDHCA-only licensed installers are not included in this directory.

Scope boundary: This directory applies exclusively to Texas-based providers operating under Texas state licensing authority. Providers licensed in Oklahoma, New Mexico, Louisiana, or Arkansas whose operations extend into Texas are only listed if they also hold a valid TDLR license. Federal installations, tribal lands, and extraterritorial jurisdictions are not covered.
