Performed a three system home care today. I checked all electrical components, cleaned, inducer reports, tested water, safety, change filters and got temp rise readings. All systems have minimum flood protection. The second floor system condenser outside is dirty and needs a cleaning because it is restricting airflow. The main floor system has a rusted evaporator coil showing potential leaks. The blower motor capacitor is bad and out of specs. The refrigerant readings I got is showing that it is low on refrigerant, which is phased out. As a courtesy I install to clean out tease for both systems that are in the basement and flushed both drain lines and tested the condensate pumps. Based on my findings, I suggest customer get a free estimate on a new system for the main floor due to age, warranty, phased out refrigerant R – 22 and the cost of repairs.
