Amazingly a Air Condition unit is not a 21st century luxury as some may assume. It's actually 1000's of years old. The ancient Romans first used a form of air conditioning by directing aqueduct water to circulate through the more wealthy home owners walls. The early Chinese around the 2nd century designed a system also using water and some form of rotating fan system. History has also recorded climate control systems designed by the Persians and the Egyptians as well. Throughout history, antiquated cooling methods have been invented and it's safe to assume these comfort control systems needed local air condition repair services. Today it is also safe to assume our more sophisticated technology requires a local air conditioning repair business to be trained to meet the needs of that technology. In fact, local air condition repair services are required to have extensive education to assure quality repair and maintenance success in respect to today's modern air conditioning systems. The primary certification a local air condition repair technician should have is a HVAC certification. HVAC certification is a comprehensive program recognized by the industry leaders in respect to the knowledge and skills needed for a successful career in local air condition repair. NATE or North American Technical Excellence is the leading non-profit certification that also provides continued education to keep pace with the ever changing technologies. When it comes to looking for a local air condition repair company be sure to ask if they employ HVAC and/or NATE certified repairmen to assure sufficient knowledge of the system and quality repair work.
