Technical Service Support

Welcome to the South Carolina Air Technical Service page. At some point all technicians need a little help and we will always be there to support our customers and the products they purchase from us. And to help you, our contactor customers, in the most effective and efficient way we encourage you to complete a startup sheet on all installations. By completing this single, double sided sheet you insure the system is performing at its best, within allowable design parameters and you have documentation that the system was started correctly. In addition to the startup sheets for either a residential or commercial system we have customized troubleshooting forms that can aid a service tech in identifying the cause or causes for a system no performing.

Jason Lotsey is our Technical Service Manager for South Carolina and his goal will be to always provide South Carolina Air Distributor customers with the highest level of customer service possible. Additionally we have created a NEW TECHNICAL SERVICE HOTLINE designed so you can be routed to the person who can help you the fastest, even if Jason is not in the office. The number to our TSM call center is 888-823-HELP (4357) and just follow the prompts.

Listed below are links to documents we think would have value to you, our valued customers. Please download and use them as you see fit to support your customers and the products your install.
