Service Call Platinum Client- Lennox system suction line and evaporator coil was frozen when I arrived. Checked filter and blower wheel to ensure we had proper airflow. After thawing out the coil I was able to determine the system was low on refrigerant. When I took the cap off the liquid line I heard it hiss. I tightened up both schrader cores in the valves. Added two lbs of r410a to the system. Changed out very weak capacitor(45+5 mfd) Customer had some questions of getting better cooling upstairs. We discussed possibilities of a zoning system or a ductless mini split system. They did not wish to have an estimate for those options at this time.
