Why You Need a Heatwave-Ready AC in 2025
India is heating up, literally. With experts warning that 2025 might outpace 2024 in record-breaking temperatures, preparing for an extreme Indian summer is no longer optional. Heat waves in Delhi and across North India are becoming more frequent, intense, and deadly. In cities like Delhi, Jaipur, and Lucknow, the temperature easily touches 46–48°C, turning homes into ovens without proper cooling. Why are heat waves dangerous? Besides the discomfort, prolonged exposure can cause dehydration, heat strokes, and in extreme cases, even fatalities especially for children and the elderly. And during a power outage or when an AC fails to cool properly, the risks multiply. That’s why investing in a heatwave-ready AC with features like fast cooling, high ambient performance (up to 52°C), and energy-efficient inverter technology is crucial in 2025. A solid split air conditioner not only handles the heat better but also offers quieter operation, air purification, and better airflow for large rooms. While split air conditioner prices vary from 30,000 to 60,000 depending on features, a smart investment now can protect your health and peace of mind through scorching months.
