Search the contractor on our license-verification page, or go straight to the state's TDLR database, and confirm the status shows Active with a current expiration date. Every HVAC contractor in Texas must hold a license from the Texas Department of Licensing and Regulation (TDLR), in one of two classes. [tdlr.texas.gov (TDLR licensing)](https://www.tdlr.texas.gov/acr/) - **TACLA (Class A)** — any size system, including commercial. - **TACLB (Class B)** — residential and light commercial systems under 25 tons. A clean verification looks like an active TDLR record, for example a TACLA The two Texas HVAC contractor license classes. Class A (TACLA) covers any size system; Class B (TACLB) covers homes and light commercial. Either is fine for a house. [Full definition](/glossary/#taclb) license active through 2027. If the name on the license does not match the company name on the truck, treat it as a red flag.

Prefer to check a specific license yourself? [Here's how](/verify-license/) . ## What certifications should an HVAC contractor have? Look for two credentials on top of the TDLR license: NATE and EPA Section 608. NATE is a leading voluntary technician certification. EPA Section 608 is federally required for any technician who handles refrigerants, including R-410A and its replacements. Neither replaces the license. [natex.org (NATE certification)](https://www.natex.org/) ### NATE A voluntary technician credential (North American Technician Excellence) on top of the required state license. A plus, not a substitute for the license. [Full definition](/glossary/#nate) (North American Technician Excellence) A voluntary industry credential requiring technicians to pass standardized exams. It is a quality signal on top of the required license, not a substitute for it. Not every licensed contractor holds it; the best ones do. Verify at [natex.org](https://www.natex.org/). ### EPA Section 608 A federal certification any technician must hold to legally handle refrigerant. Required by law, not optional. [Full definition](/glossary/#epa-608) A federal requirement for any technician handling refrigerants. It applies to all refrigerant types, including R-410A and its replacements. ![An HVAC technician in a polo shirt servicing a residential outdoor condenser unit beside a house, with gauges and tools.](/_astro/hvac-service-call.NQA2-yAy_1J4FWL.webp "An HVAC technician in a polo shirt servicing a residential outdoor condenser unit beside a house, with gauges and tools.")

A complete estimate is itemized: equipment make, model, and SEER2 rating; labor; the local mechanical permit fee as a line item; old-system disposal; and manufacturer and contractor warranties stated separately. An itemized written estimate is what lets you compare bids fairly, so treat a vague lump sum as a warning sign. The FTC advises getting estimates in writing before you hire. [FTC (hiring a contractor)](https://consumer.ftc.gov/articles/how-avoid-home-improvement-scam) A complete estimate Itemized - Equipment Make, model, and SEER2 rating - Labor Hours and any subcontractors - Permit Local mechanical permit fee, line-itemed - Disposal Removal and haul-away of the old unit - Warranties Equipment and labor, stated separately A single lump sum with none of these lines is the red flag — you can't compare it, and a missing permit line means no permit is being pulled. Walk away from these - Lump-sum quote with no line items - No permit fee listed (means no permit is being pulled) - Pressure to sign the same day - A price drastically lower than other quotes ## What SEER2 rating is worth paying for in Texas? The legal minimum for new split-system air conditioners in Texas is 14.3 SEER2, the DOE standard that replaced SEER on January 1, 2023 — not 15.2, which is the Energy Star threshold. Higher ratings cut monthly energy costs, and over an 18-year system life the best-available 23.5 SEER2 tier saves about $6,724 versus base efficiency per DOE data. [energy.gov (DOE/FEMP)](https://www.energy.gov/cmei/femp/purchasing-energy-efficient-residential-central-air-conditioners) Lifetime energy savings vs. base efficiency (DOE/FEMP, 18-year hot-humid South system life) Efficiency tier SEER2 rating Lifetime savings Base (minimum) 13.4 SEER2 — Energy Star 15.2 SEER2 $1,853 Best available 23.5 SEER2 $6,724 Over an 18-year system life, efficiency and reliability matter more than the sticker price. A unit at the legal minimum costs less today, but the best-available tier saves roughly $6,724 in energy over that lifespan, so the cheapest quote is rarely the lowest total cost of ownership. ## What should I ask about post-installation support? Before you sign, ask whether the company regularly serves New Braunfels, what its response-time policy is for urgent summer calls, and what the maintenance plan covers. In a Central Texas summer, a contractor who is slow to answer an emergency call is the difference between a same-day fix and days without cooling, so responsiveness is worth weighing alongside price. [ENERGY STAR (maintenance checklist)](https://www.energystar.gov/saveathome/heating-cooling/maintenance-checklist) - Does the company regularly serve New Braunfels, or is it stretching from San Antonio or Austin? - What is the response-time policy for urgent summer calls? - What does the maintenance plan include, and is it binding or month-to-month? Once you have a shortlist, work through the move-in and decision steps in our [new homeowner HVAC guide](/guides/new-homeowner-hvac-guide-new-braunfels/) to know exactly what to check before your first Texas summer. ## Questions homeowners ask What is the difference between a TACLA and TACLB license in Texas? TACLA (Class A) covers systems of any size, including commercial; TACLB (Class B) covers residential and light-commercial systems under 25 tons. For a typical home a Class B contractor is fully qualified. Both are issued by the [Texas Department of Licensing and Regulation](https://www.tdlr.texas.gov/acr/). What is NATE certification for HVAC? NATE (North American Technician Excellence) is the leading voluntary technician certification, earned by passing standardized exams. It is a quality signal layered on top of the legally required TDLR license, not a replacement for it. [Source: NATE](https://www.natex.org/). What is EPA Section 608 certification? A federal certification required for any technician who handles refrigerant. Under the Clean Air Act, a technician charging or recovering refrigerant without it is working illegally. [Source: U.S. EPA](https://www.epa.gov/section608/section-608-technician-certification-requirements). Why is a permit required for AC replacement in New Braunfels? A mechanical permit ensures the installation meets local building code, and a reputable contractor pulls it and lists the fee on your quote. A missing permit line is a red flag, and an uninspected install can create insurance and resale issues. [Source: City of New Braunfels](https://www.newbraunfels.gov/3433/Building-Permits). What risks come with hiring an unlicensed HVAC contractor? Unlicensed work can void your equipment manufacturer warranty, get a homeowner insurance claim denied, and eliminate your right to file a complaint. The [TDLR](https://www.tdlr.texas.gov/acr/) can only act on licensed contractors. If someone is injured on the job, you may face personal liability. ## Before you hire - ### TDLR License Texas law requires all HVAC contractors to hold either a TACLA or TACLB license.
