Called out today to replace the filter drier on the roof. Removed and brazed in new filter drier. Performed a pressure test @450 for 30 minutes. Pulled a vacuumed down to 500 microns. Charged system to proper specifications. Tested equipment. System is cooling properly at this time. Client leaves March 10th for Canada and would like to have his first preventative maintenance performed before then. I will have the office reach out to the client to schedule. Thank you for always choosing Total Air!
