Koolco Mechanical was started by Nick and his wife Helen in February 1987. Our business philosophy was simple: Provide the best possible service to the customer, and stand behind all our work. During the time we started our business, the housing construction market was booming. Instead of jumping on the construction band wagon like every new air conditioning company was doing at that time, we decided to focus our efforts on customer service. We are local to Ventura and Santa Barbara counties with our headquarters based out of Oxnard.
