April has been a scorching month for summer products like air-conditioners, refrigerators, air-coolers, soft drinks, and ice creams, with sales soaring 40-50%. This surge has led to concerns among appliance manufacturers about meeting demand, especially in the south and east where sales have spiked 150-200% due to ongoing heatwaves. The north, the largest market for cooling appliances, is yet to experience the full impact of the heatwave. Manufacturers warn of possible shortages in May as component planning did not anticipate such high demand, and it's challenging to expand production on short notice.
