According to EVNHANOI, since the early days of April 2025, when the weather started to get warm, electricity consumption in Hanoi households has soared.
The main reason for this spike is the frequent use of air conditioners, electric fans, and cooling appliances, especially during peak hours from 10:00 AM to 2:00 PM and 7:00 PM to 11:00 PM.
Mistakes in Using Air Conditioners That Drive Up Electricity Bills
Underestimating Outdoor Temperatures:
As per EVNHANOI, the outdoor temperature directly impacts the electricity consumption of air conditioners. For every 1°C rise in temperature, electricity consumption can increase by 2-3%.
If the outdoor temperature rises by 5°C, you may end up paying up to 10% more on your electricity bill due to running your air conditioner at full capacity. The extreme heat of 35-40°C in Hanoi pushes these cooling systems to their limits, resulting in skyrocketing electricity costs.
Setting Extremely Low Temperatures – An Expensive Habit:
Many people tend to set their air conditioners at 18-20°C, but this practice is costly. Experts recommend maintaining a temperature of 25-26°C as the ideal setting. For every 1°C decrease from this ideal temperature, the air conditioner consumes an additional 1.5-2% of electricity. Over time, this difference can double your electricity bill without you realizing it.
Using Air Conditioners Simultaneously With Other High-Power Appliances:
Operating air conditioners concurrently with appliances like induction cookers, washing machines, and water heaters, especially during peak hours, is a recipe for disaster. It pushes your home electrical system to its limits, causing the electricity meter to spin uncontrollably and resulting in uncontrollably high monthly electricity bills.
Smart Solutions for Energy-Efficient Air Conditioner Use
To keep your electricity bills in check during the hot season, experts advise setting your air conditioner temperature to 25-26°C or higher. This temperature range strikes a balance between comfort, health, and energy efficiency.
Additionally, leveraging technology can be a powerful tool. Utilize apps such as EVNHANOI, EVNHCMC CSKH, and EPoint to closely monitor your daily electricity consumption. The electricity consumption alert feature will help you promptly identify abnormal usage patterns and make necessary adjustments to your consumption habits to prevent waste.
- Turn off all unnecessary electrical appliances when not in use.
- Avoid using high-power appliances during peak hours (10:00 AM to 2:00 PM and 7:00 PM to 11:00 PM).
- Minimize simultaneous use of multiple electrical appliances to reduce the risk of overloading and electrical accidents.
- Opt for energy-efficient devices such as LED lights, inverter air conditioners, and appliances with energy efficiency labels.
These small measures will not only reduce your expenses but also contribute to preserving the valuable electrical energy resources during the hot season.
