• What “good” looks like: LED lighting that consumes less power and lasts longer.
• Common mistake: Not considering the impact of lighting, especially in machines that are lit continuously.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Ignoring the need for refrigeration	Assuming all machines use similar power; underestimating costs.	Differentiate between refrigerated and non-refrigerated models; check specifications.
Purchasing an older, inefficient model	Higher electricity bills over the machine’s lifespan, negating initial savings.	Prioritize Energy Star certified or newer models; compare energy ratings.
Placing machines in hot environments	Refrigeration system works overtime, significantly increasing energy consumption.	Locate machines in cool, well-ventilated areas, away from direct sunlight or heat sources.
Neglecting regular maintenance	Reduced efficiency, potential for component failure, higher energy use.	Schedule periodic cleaning of coils, checks of seals, and overall system inspection.
Not knowing your local electricity rate	Inaccurate cost projections; inability to budget effectively.	Review your utility bill for the precise cost per kWh and use it for all calculations.
Overlooking lighting energy consumption	Adds to the overall electricity bill, especially if not using LEDs.	Ensure machines use LED lighting; consider if internal lights need to be on 24/7.
Failing to check door seals	Refrigerated air escapes, forcing the compressor to run more frequently.	Inspect and replace worn or damaged door seals regularly to maintain insulation.
Assuming all compressors are equal	Older compressors are less efficient and use more power than newer models.	Research compressor technology; newer models often feature more efficient variable-speed compressors.
Not considering ambient humidity	High humidity makes cooling systems work harder, increasing energy demand.	Place machines in areas with moderate humidity if possible, especially for refrigerated units.
Buying based solely on upfront cost	Higher long-term operating costs can outweigh initial purchase price savings.	Calculate the total cost of ownership, including energy consumption over several years.
