Carrier heat pump with air handler in stalled in 2010. All electrical connections are tight with no corrosion. Heat strips are pulling proper amperage. Evaporator coil is clean. Blower wheel has slight build up starting to form. X13 blower motor is acceptable. Compressor and condenser fan motor are acceptable. Refrigerant levels are in range. Hose bib in the back is leaking into the wall and needs to be replaced. Customer does not know schedule and was not able to set an appointment for a plumber right now.
