Aircon is the word most people in the UAE actually use for their air conditioning, and an aircon mechanic is the person who keeps it running through a summer that can top 45 degrees.
Cooling technicians are the people who keep the UAE bearable, from a single bedroom split to the fan coils and chilled-water systems in a whole tower.
When your AC quits in August, "aircon technician near you" is exactly what you type, because a technician ten minutes away beats a cheaper one on the far side of the city.
