Found lots of oil inside HVAC System condenser compartment. Leak checked and found one high side fitting leaking. Recovered charge. fixed leak held nitrogen and then pulled 500 micron vacuum. Weighed in factory charge of 8 lbs 4 Oz's. Started unit and watched pressures and temps. Pressures ok but where t stat is located is a very hot area and unit will never cycle and it will freeze. relocated t stat to another room ok wire needs secured yet. Also there was no trap on evap drain. Plumbed in new trap and line. Unit is cycling. Compressor did sound loud upon startup but then smoothed out.
