Super tune up performed today on a ten year old straight electric system. Heat strips are pulling proper amperage however low airflow across the evaporator coil is causing them to overheat. Evaporator coil and blower wheel are very dirty and air flow is being restricted. Refrigerant levels are showing low airflow across the coil as well. Compressor is amping high upon start up and condenser motor is amping high while running and motor is leaking oil. Outdoor unit was washed and waxed. Customer declined repairs at this time. All estimates are being emailed to the customer.
