Complete 2 system a/c repair and preventative maintenance check. Found basement system with brittle igniter and overheated transformer. Replaced both. Cleared drain line and changed filter. Blower whee is clean and all safety switches have been tested. System is heating properly. Upstairs system looks good with good igniter and clean flame sensor. All electrical components are good and filter is changed. Blower wheel is collecting small amount of distance and debris. If worsens by next visit will recommend a cleaning.
