How to Find the Right Provider
Verify State Licensing
Texas requires HVAC contractors to be licensed by the Texas Department of Licensing and Regulation (TDLR).
- Class A license for contractors doing work over $50,000
- Class B license for work between $10,000-$50,000
- Verify licenses at TDLR.texas.gov
- Ask for license number and insurance certificate
Check Certifications
Look for technicians with industry certifications beyond basic licensing.
- NATE (North American Technician Excellence) certification
- EPA 608 certification for refrigerant handling
- Manufacturer certifications (Carrier, Trane, Lennox, etc.)
- Ask about ongoing training programs
Get Multiple Estimates
For major repairs or replacements, always compare multiple quotes.
- Request in-home assessments, not phone estimates
- Get itemized written quotes
- Compare equipment brands and warranties
- Ask about financing options for major purchases
Evaluate Equipment Recommendations
Understand what you're being sold and why.
- Ask about SEER ratings (higher = more efficient)
- Right-sizing: bigger isn't always better
- Compare warranty terms across brands
- Ask about rebates and tax credits for efficient systems
Review the Contract
Before signing, ensure everything is documented.
- Equipment model numbers and specifications
- Total cost including labor and materials
- Timeline for completion
- Warranty terms and what's covered
Red Flags to Watch For
- No TDLR license or won't provide license number
- Gives quote without inspecting your system
- Pressures you to decide immediately
- Suggests oversized equipment for your space
- Won't provide written estimate or contract
- Demands large upfront payment
- No physical business address
- Unusually low prices compared to other quotes
Questions to Ask Before Hiring
Are you licensed and insured?
Texas law requires HVAC contractors to be licensed. Insurance protects you from liability.
What size system do I need?
Proper sizing requires a load calculation. An oversized system wastes energy and causes humidity problems.
What SEER rating do you recommend?
Higher SEER means better efficiency. In Texas heat, 16+ SEER often pays for itself in energy savings.
What does the warranty cover?
Understand both manufacturer warranty and labor warranty. Some companies offer extended coverage.
Do you offer maintenance plans?
Regular maintenance extends system life and catches problems early. Many plans include priority service.
How long will the installation take?
A typical replacement takes 1-2 days. Longer timelines may indicate scheduling issues.
