Persistence: Problem-solving sometimes requires a good deal of patience and persistence. Technicians should be able to stay focused and determined, even when dealing with stubborn or recurring issues.


Beyond the technical and safety aspects, a successful commercial ice machine technician must also have excellent customer service skills and understand the industry’s nuances.

Communication: Technicians must be able to clearly explain technical issues to non-technical customers, both verbally and in writing. They need to provide clear, concise, and jargon-free explanations about the problem and the steps taken to solve it.

Professionalism: An understanding of industry standards for professional behavior is essential. This standard requires punctuality, cleanliness, respect for the customer’s property, and professionalism.

Hygiene: Understand handwashing, glove practices, clean tools, and professional appearances in customer-facing environments.

Responsiveness: Technicians should respond promptly to service calls, acknowledging and addressing customer concerns effectively and efficiently.

Empathy: Understanding and addressing the customer’s frustration or inconvenience is critical when their ice machine isn’t working. Technicians should demonstrate empathy and reassure customers that they do everything possible to resolve the issue quickly.

Industry Awareness: Technicians should have a broad understanding of the ice machine industry, including knowledge about different manufacturers, the latest trends, and emerging technologies. This knowledge is crucial to provide informed advice to customers.

By mastering these skills, a technician can provide high-quality customer service, increasing customer satisfaction and loyalty and ultimately contributing to the business’s success. Generate fewer personality-related complaints.


Location: Solve for needed condenser airflow exchanges, drainage, and power specification. Consider the noise pollution impact of operation sequences such as harvest will not impact customers.

HVAC: Determine the impact of the ice machine (refrigeration systems) on the HVAC systems.

Remote Condenser: Remote condensers present unique requirements of refrigerant line sizing, rise, run, and oil return consideration. Calculate the length and effective length and interpolate performance charts for useability.

One consistent question we receive is, "why don't you offer hands-on training?"

eTech HVACR Training Center does not offer hands-on training because it is not practical.

Technicians must come to FACTORY refrigeration and ice machine training with essential refrigeration and electrical troubleshooting skills. eTech training fills in knowledge gaps related to the ice machine.

Hundreds of specific model numbers are operating in the field, and it is impractical to attempt to train to any specific model.

The commercial ice machine has very little to do with air conditioning and commercial refrigeration (directly). Ice machines are operationally robotic and a frequent target of health inspectors since they are commonly poorly maintained by field personnel who are not “in the know.” Mold growth and backed-up drains are the most cited issues during health inspections.

Since the ice machine is robotic, the electrical, refrigerant and mechanical aspects are much different from one another. 

Is there a sample course or assessment quiz? (yes).
