Do I need EPA 608 certification to work on air conditioners?

Answer

1. If you'll maintain, service, repair or dispose of equipment that could release refrigerant, yes: the EPA requires Section 608 certification for that work. It's a federal certification, separate from your Texas TDLR registration, so most HVAC techs have both.
