Two system AC Maintenance. Homeowner said they had no issues other than high energy bills. Replaced both 20x25x1 filters. Applied total-c drain cleaner to primary drain. Neither system is retaining water and is draining properly. Both air distribution motor/wheels need to be pulled and cleaned. No float switches present. Water rinsed condenser coils. Checked all electrical components Found downstairs system condenser has pressure switch bypassed. Upstairs post coil wash delta temperature drop across the coil was 20 to 21°F Downstairs Post wash Delta temperature drop across the coil was only 14°F Priority Recommendations: - pull clean air distribution assemblies - float switches on both systems - air seal air leaks on upstairs evaporator coil - capacitor for outside equipment - hard start kits on both systems - surge protection on all components. - High voltage disconnect for outside downstairs equipment Recommend comfort advisor consultation for future replacement option.
