• Communicate professionally with customers and the dispatch/office team.
• Participate in the on-call / rotating schedule as needed.
• Perform all work to code and company safety standards.

• EPA 608 Certification (required to handle refrigerant).
• Proven ability to diagnose issues and clearly communicate repair or replacement options to homeowners.
• Strong customer-service and communication skills; comfortable presenting and selling solutions in the home.
• Valid Texas driver's license and clean driving record; approved to drive under company insurance requirements.
