Record-Breaking Air Conditioner Usage This Summer

According to recent data collected by Panasonic, 2025 marks a record year for air conditioner usage across all 47 prefectures in Japan. Residents used their systems for over 1,000 hours during the summer months, from June to August, with Okinawa topping the list at an impressive daily average of 15.64 hours. As worries about extreme heat began to rise, it became evident that preparation for the upcoming heating season is crucial.

The Japan Meteorological Agency revealed that summer 2025 was the hottest since records began in 1946, raising alarms regarding energy consumption as air conditioning units were pushed to their limits. These findings highlight the importance of regular maintenance, particularly as we approach the fall and winter months.

Survey Insights on Air Conditioner Maintenance

Panasonic conducted a survey regarding air conditioner maintenance habits and found that 43% of respondents did not clean their units at all over the summer. Alarmingly, nearly half (48%) admitted to never performing a ritual known as “summer closing” — a crucial maintenance practice designed to prepare air conditioners for the winter heating season.

When asked why they neglect this maintenance, a staggering 52% cited it as too bothersome. Others reported uncertainty about how to clean their units (26%) or felt that hiring professionals was too expensive (21%). Surprisingly, 32% admitted to practicing unsuitable cleaning methods, which could lead to malfunctions in their units.

Ranking of Air Conditioner Usage Across Japan

Panasonic’s analysis of Eolia app user data revealed that nationwide, average cooling usage reached the highest levels since observations began. Okinawa emerged as the leader with a total of 1,438.77 hours, while Hokkaido documented a dramatic increase in usage, averaging an additional 1.52 hours per day, summing to about 139.90 hours more than previous years. These increases correlate with the record temperature variations reported — 3.4 degrees higher in Northern Japan, 2.3 degrees in Eastern Japan, and 1.7 degrees in Western Japan.

The Importance of Cleaning: Lessons from Panasonic's Air Meister

Fuko Fukuda, an Air Meister from Panasonic, emphasizes the crucial role of summer maintenance in keeping air conditioners functioning well. Fukuda provides insights into proper cleaning procedures to prevent mold buildup and inefficiencies in unit operation.

As indoor humidity is a breeding ground for mold, she stresses that air conditioning units used extensively during summer need special attention before the winter. Understanding the importance of internal cleaning mechanisms, such as using the internal clean function or running the unit in fan mode post-cooling, can dramatically improve air quality and efficiency.

Effective Summer Closing Techniques

1. Utilize the internal clean function: If your unit has it, enabling this feature helps dry the internal components to prevent mold growth.
2. Perform filter maintenance: Regularly cleaning or replacing filters can significantly improve air flow, maintaining efficiency and lowering energy bills. A dirty filter can increase electricity usage by up to 25%!
3. Wipe visible surfaces: This includes dusting down the vents and flaps to eliminate potential mold food sources.

Fukuda warns against DIY cleaning methods that involve chemicals or incorrect techniques, as these can damage the unit or worsen the fouling. Engaging a professional for deeper cleaning is often the safest option.

Final Thoughts on Preparation

With predictions hinting at continued extreme weather, preparing air conditioning units for the transition to heating usage is more vital than ever. Panasonic remains committed to helping consumers maintain their appliances effectively to ensure safe and comfortable indoor environments.

In conclusion, proper maintenance and timely summer closing practices can lead not only to better performance but also improved energy efficiency and reduced costs as the weather inevitably changes. As a testament to the changing climate and consumers' reliance on technology, this summer's data serves as a crucial reminder of the importance of home appliance care.
