How to Choose an AC Company in Texas: 9 Things to Check
Hiring the wrong HVAC company can mean overpaying, shoddy work, or a system that never runs right. In Texas — where your AC is essential equipment, not a luxury — it pays to vet a contractor before they touch your system. Use this 9-point checklist whether you are booking a repair, a tune-up, or a full installation.
1. Verify the TDLR License
Texas requires HVAC contractors to hold an Air Conditioning & Refrigeration license from the Texas Department of Licensing and Regulation (TDLR). Ask for the license number and confirm it on the TDLR website. An unlicensed contractor is an immediate red flag.
2. Confirm Insurance
A legitimate company carries general liability and workers’ compensation insurance. Ask for a certificate of insurance before work begins — if a technician is injured on your property and the company is uninsured, you could be on the hook.
3. Check EPA Certification
Any technician handling refrigerant must hold EPA Section 608 certification. It is a basic, non-negotiable credential for legal, safe AC work.
4. Read Recent Reviews — Not Just the Average
A 4.8-star average means little if the recent reviews are full of complaints. Read the last 3–6 months and look for patterns: punctuality, clean work, honest diagnostics, and how the company responds to criticism.
5. Insist on a Written, Itemized Estimate
Avoid anyone who quotes a replacement price over the phone without inspecting your system. A proper estimate lists equipment, labor, and warranty terms in writing so you can compare quotes apples-to-apples.
6. Ask About Sizing (for Installs)
For a new system, the right contractor performs a Manual J load calculation rather than guessing by square footage. Correct sizing is the single biggest factor in comfort and efficiency — and a contractor who skips it is cutting corners.
7. Look for NATE-Certified Technicians
NATE certification (North American Technician Excellence) is an independent, industry-recognized credential that signals a technician’s training and competence. It is a plus, not a requirement, but a good sign.
8. Understand Warranties and Financing
Ask what is covered and for how long — both the manufacturer’s equipment warranty and the company’s labor warranty, which should be in writing. For larger jobs, ask about rebates and financing options.
9. Watch for Red Flags
Be cautious of companies that:
- Pressure you into an immediate, expensive replacement
- Quote a price without inspecting the system
- Cannot or will not provide a license number
- Ask for large cash payment upfront
- Have no verifiable local address or reviews
Why Local Matters
A company with a real local presence in your area knows the regional climate, permitting, and common system types — and is easier to hold accountable. Texas-specific experience with extreme summer loads and the occasional hard winter freeze is genuinely valuable.
