How to Choose the Right HVAC Company in Texas

With hundreds of HVAC companies operating in Texas, choosing the wrong one can mean shoddy work, unlicensed technicians, or surprise charges. Here's exactly what to look for.

Verify Texas HVAC Licensing

In Texas, HVAC contractors must hold an Air Conditioning and Refrigeration contractor license issued by the Texas Department of Licensing and Regulation (TDLR). You can verify any contractor's license at the TDLR website. Always ask for the license number before hiring — any legitimate contractor will provide it immediately.

Unlicensed HVAC work in Texas can void manufacturer warranties, fail city inspection, and in worst cases create safety hazards with refrigerant or gas line work.

5 Questions to Ask Before Hiring

• Are you licensed in Texas for HVAC work? — Ask for the TDLR license number and verify it.
• Do you carry liability insurance? — Request a certificate of insurance. Any legitimate contractor has it readily available.
• Do you provide written estimates before starting? — Never accept a verbal-only quote. Get the scope and price in writing.
• What brands do you service and install? — Reputable HVAC companies service all major brands, not just one manufacturer.
• Do you offer a warranty on parts and labor? — Quality HVAC companies stand behind their work with at least a 1-year labor warranty.

Red Flags to Avoid

• No physical address or Texas license number provided
• Demands full payment upfront before any work begins
• Pressure to sign immediately or "lose the deal"
• Quotes significantly lower than all competitors (a sign of cutting corners)
• No written estimate provided
• Technician arrives in an unmarked vehicle with no company identification
