Your AC goes out on a 103-degree afternoon. You need someone fast. That's exactly when unscrupulous contractors make their money — pressuring panicked homeowners into expensive replacements they don't need. Here's how to protect yourself.
Every HVAC company and technician operating in Texas must be licensed through the Texas Department of Licensing and Regulation (TDLR). You can verify any contractor's license at tdlr.texas.gov in under 2 minutes. If they can't provide a license number, walk away.
💡 The most common scam in DFW: a contractor tells you your compressor is dead and you need a full new system — when in reality, only the capacitor failed (a $200–$300 part). Always get a second opinion on any repair over $500.
A legitimate HVAC company will come out, inspect your system, and tell you exactly what's wrong before asking for a commitment. United National HVAC does this at no charge — because an informed customer is a customer who trusts you.

Verify they hold a valid license through the Texas Department of Licensing and Regulation (TDLR) at tdlr.texas.gov. Also check for general liability insurance and a physical business address.
