In 1989 during United CoolAir’s first year of operation, a 5 Ton C-Series was deployed by distributor Air Temp, to the NY Telephone building at 227 East 30th Street in New York City. After 27 years of service this particular C-Series is still in operation today and continues work efficiently and effectively without exceeding normal maintenance requirements. New York City is populated with many buildings that due to their antiquated architecture require HVAC units that can fit inside a structure and within tight quarters. This particular C-Series unit was everything the customer needed and performed well beyond expectations. After breaking into this market and the satisfaction received, United CoolAir was able to expand and flourish for decades into the future.
