Performed Ac maint on 2008 Lennox system. Cycled system for cooling. Checked outdoor unit electrical and system components. Amp draws on compressor and condenser fan motor are fairly high, but within range. Secondary motor controls are in range, primary motor control is in good condition. Amp draws on compressor start up are high. Pulled condenser fan motor to thoroughly wash out condenser coil. Condenser coil is really deteriorated at a couple different spots and refrigerant lines are very exposed. Reassembled unit. Replaced 1 inch filter. Checked indoor unit electrical and system components. Blower wheel is starting to accumulate dust. Could not access attic due to full closet. Refrigerant levels are in range and system is producing a good temperature split.
