Maintaining a cold storage room or freezer in proper working order is essential for preserving food and products, but also for controlling energy costs. Many users end up spending more electricity than necessary due to simple habits that seem harmless. In this article, we've compiled 5 common mistakes that can increase your energy bill and show you how to correct them with small actions.

1. Opening the door too frequently or leaving it open.

Every time the door of a chamber or trunk is opened, cold air escapes and hot air enters. This forces the compressor to work harder to restore the ideal temperature, increasing energy consumption.

For example, in a store where the door is opened several times an hour, the bill can increase by up to 15%. A simple solution is to install door sensors or alarms that alert when the door remains open for too long, ensuring efficiency without compromising access to products.

2. Temperatures set outside the ideal range.

Setting temperatures too low does not accelerate cooling; on the contrary, it unnecessarily increases electricity consumption. Beverage coolers, for example, operate efficiently between 3°C and 5°C.

Using Carel digital controllers allows you to program the ideal temperature and keep it constant, avoiding energy waste and protecting the products.

3. Poor air circulation inside the chamber.

An improper arrangement of products can block the circulation of cold air, forcing the equipment to work harder to maintain the temperature. This not only increases the bill but can also compromise food preservation.

To correct this, keep the air vents unobstructed and distribute the products to allow for free airflow. In some models, internal fans help maintain a uniform temperature throughout the chamber.

4. Lack of maintenance of capacitors and filters.

Dirty condensers or clogged filters hinder heat exchange, forcing the compressor to consume more energy. Regular cleaning can reduce consumption by up to 10%, in addition to extending the equipment's lifespan.

Regular inspections and preventive maintenance, performed by qualified technicians, ensure that everything works efficiently and safely, preventing unpleasant surprises.

5. Ignoring alarms and indicators from the controllers

Many users ignore temperature or humidity alerts on the controllers. These signals indicate that the equipment is operating outside of ideal parameters, increasing consumption and potentially causing product waste.

Carel remote monitoring allows you to receive real-time alerts, intervening quickly before losses or unnecessary expenses occur.

Conclusion

Avoiding these common mistakes is simple and effective: small changes in usage habits and the correct use of controllers and sensors can significantly reduce electricity bills, extend the lifespan of equipment, and ensure optimal product preservation.

Investing in preventative maintenance and appropriate technology is therefore a smart way to save money and protect the food and beverages we store every day.
