When hiring an on-site technician, verify their credentials and insurance coverage to avoid liability for accidents or subpar work. Request references or read online reviews to gauge reliability. Clearly outline the scope of work, pricing, and timelines in a service agreement to prevent disputes. Ensure the technician is familiar with the specific equipment or systems needing service. For high-risk industries like electrical or gas systems, always prioritize licensed professionals. Avoid technicians who demand full payment upfront or lack transparent communication.
