Performed 6 month maintenace work on 4/26/21. Process included blowing out overflow line which caused a leak under bathroom sink. Did not notice leak until 4/27/21. Called Joplin and they were at my home within the hour. Jason did a GREAT JOB and repaired the leak. This is the reason Joplin has been my one and only A/C & Heating Specialists for the past 21 years.
