Completed furnace maintenance on main system, heat pump maintenance on attic system, and mini split maintenance. On main system I found failing capacitor and blower wheel/motor covered in dirt. Static improvement has helped system a lot. Filter will need changed soon. Attic system looks great however heat pump outdoors has a capacitor almost out of range. It also had the condensing fan motor blades hitting the plastic walling. I was able to correct that for now. Talked with customers about findings and showed pictures. Customer approved blower wheel cleaning and blower capacitor replacement. Will need to return first call Wednesday morning to complete work. Systems are operating at departure.
