86% of homeowners lack detailed knowledge of HVAC components — which means most people make this decision without the tools to evaluate their options. Here are those tools.

Step 1

Start with the Texas license

Every HVAC contractor in Texas must hold a license issued by the Texas Department of Licensing and Regulation (TDLR). There are two classes:

  • TACLA (Class A) — any size system, including commercial.
  • TACLB (Class B) — residential and light commercial systems under 25 tons.

To verify a contractor, visit tdlr.texas.gov/verify.htm, enter the contractor’s name or license number, and confirm the status shows Active with a current expiration date.

License verified — TDLR TACLA #87412C, active through 2027
This is what a clean verification looks like. If the name on the license does not match the company name on the truck, treat it as a red flag.
The risk of an unlicensed contractor
Using an unlicensed contractor can void your equipment manufacturer warranty, result in denied homeowner insurance claims, and eliminate your right to file a TDLR complaint. If someone is injured on the job, you may face personal liability.
Step 2

Verify certifications

Two credentials separate the best contractors from the rest. Neither replaces the TDLR license — they sit on top of it.

NATE (North American Technician Excellence)

A voluntary industry credential requiring technicians to pass standardized exams. It is the highest technician certification in the industry. Not every licensed contractor holds it — the best ones do. Verify at natex.org.

EPA Section 608

A federal requirement for any technician handling refrigerants. It applies to all refrigerant types, including R-410A and its replacements.

Step 3

Get three written estimates

A complete estimate is itemized. Here is what each one must include:

A complete estimate includes
  • Equipment make, model, and SEER2 rating
  • Labor hours and any subcontractors
  • Comal County permit fee as a line item
  • Old system disposal fee
  • Manufacturer (equipment) and contractor (labor) warranties, stated separately
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

Step 4

Understand SEER2 efficiency and what it is worth

SEER2 replaced SEER as the U.S. Department of Energy testing standard effective January 1, 2023. The minimum for new systems in Texas (southern states) is 15 SEER2. Higher ratings reduce monthly energy costs — over an 18-year system life the difference is real:

Lifetime energy savings vs. base efficiency (DOE/FEMP, 18-year hot-humid South system life)
Efficiency tierSEER2 ratingLifetime savings
Base (minimum)13.4 SEER2—
Energy Star15.2 SEER2$1,853
Best available23.5 SEER2$6,724

83% of consumers rank something other than cost as their top priority when choosing an HVAC system, with 38% prioritizing reliability above all else. The cheapest system is rarely the right answer.

Step 5

Ask about post-installation support

Before you sign, ask:

  • 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?
Why responsiveness matters
55%

of all negative HVAC reviews cite unresponsiveness as the reason for the complaint.
