A Day in the Field

You roll up to your first light commercial call, greet the customer, and get to work. One visit might have you tuning a high-velocity system; the next could involve diagnosing a ductless unit or restoring heat to a steam or hot-water system. Using specialized tools, you tackle airflow hiccups, fuel delivery concerns, refrigerant issues, and electrical faults—then translate your findings into plain language that helps customers boost comfort, efficiency, and safety.

Midday, you take a few minutes to coach a junior technician, sharing practical tips that build skill and confidence. Before heading to the next job, you update detailed service notes and verify truck inventory so you’re always prepared.

• Work in a culture grounded in integrity, excellence, and a positive attitude.
• Get hands-on with a wide variety of HVAC systems—no two days are the same.
• Grow through mentoring opportunities and supportive leadership.

• Diagnose, maintain, and repair forced-air, steam, hot water, oil, high-velocity, and ductless HVAC systems.
• Resolve airflow, fuel, refrigerant, and electrical challenges using specialized tools.
• Educate customers on improvements for comfort, energy efficiency, and safety.
• Provide guidance to junior technicians.
• Keep accurate service logs and manage truck stock.
