As the summer heat rages on in Japan, homeowners are facing the challenge of keeping their air conditioners running beyond 1200 hours. The article provides a comprehensive guide on how to maintain and extend the lifespan of the air conditioning units. It also explains the importance of proper upkeep in increasing the efficiency and reducing the energy consumption of these cooling devices. Consumers are urged to adhere to these maintenance strategies to ensure longevity and proper functioning of their air conditioners.

In Japan, where the humidity combined with the heat of summer can be stifling, air conditioning units are deemed essential for survival. There is a high social value placed on energy efficiency and sustainability, pushing homeowners to strive for proper maintenance of their appliances to reduce energy consumption. The laws in Japan enforce energy-saving efforts by promoting energy-efficient air conditioners and encouraging regular maintenance.

In the US and EU, while air conditioning is common, the emphasis on regular maintenance may not be as strong. Energy efficiency is a priority but the climate and social attitudes may vary, leading to less emphasis on sustained, long-term use of air conditioning. Instead, there's more focus on renewable sources of energy and advanced cooling technology.
