Upon my arrival in Smithville I did AC Maintenance. Arrived on site and spoke with Jeff regarding the scheduled cleaning of two mini-split air handlers. During the cleaning of the first unit, we discovered that the wall bracket holding the mini-split head was mounted directly into the drywall without the use of anchors, resulting in an unstable installation. We will provide a separate estimate to properly reinstall the bracket for the middle unit located in the center section of the building. Both indoor units have been cleaned. However, we are leaving the middle unit powered off due to water dripping caused by an improper slope. Further evaluation and correction will be needed before it can be safely operated.
