Hungary's sweltering summer is reshaping its workforce, as professionals from diverse trades retrain as HVAC (Heating, Ventilation, and Air Conditioning) technicians to meet soaring demand for air conditioning, now a necessity instead of a luxury. As temperatures climb, demand has surged for affordable air conditioning units, many manufactured in China, along with the need for skilled technicians to install these systems. On the fourth floor of a Budapest apartment building, Ferenc Pallai is back at work, fitting yet another air conditioner. "We're putting in the fourth AC unit in this building today. The tenants were complaining about the heat, so we've been here working for a week to get the units," said Ferenc Pallai, owner of Master Cool Klimatechnika. Pallai's business has always thrived in summer, but this year’s demand has reached unprecedented heights. "We have been really busy these past few months, and I'm already booked up even after summer. I think we'll stay busy at least through October," said Pallai. His crews work year-round now, driven by hotter summers, and a surge in budget-friendly, dual-purpose cooling-heating systems -- many of them made in China. But keeping up with the demand requires more than just equipment -- it requires people. As more Hungarians rush to cool their homes, the country finds itself in a different kind of problem: a race to train the people qualified to install AC units. At a training center Ezkimo Academia, Karoly Marton trains the next generation of HVAC technicians. He says demand for his courses has exploded. "The number of students has definitely gone up. It's become a really in-demand profession. These days, every building needs to have air conditioning. It wasn't like that before. AC used to be a luxury, now it's a standard. That shift has made more people want to learn the trade," said Karoly Marton, owner of Ezkimo Academia. These days, Marton is retraining everyone from waiters to musicians, not just students with technical backgrounds. "It's not uncommon to have IT people, former violinists, people from all different backgrounds studying to become technicians," said Marton. In Hungary, it takes about three months to become certified, and the payoff is real. "A good climate technician can earn in a few days the money that the average person earns in a month," said Marton. SHOTLIST: Budapest, Hungary - Recent 1.
