-Performed CMA full service on 6 split systems and 1 mini split system. -Office split system (Payne 0460) outdoor fan motor capacitor & compressor capacitor tested weak. Recommend replacement of dual run capacitor. Provided estimate $322.61. -Third floor split system: Found condensate pump float switch not providing proper voltage to system. Recommend replacement of pump. Bypassed float switch to leave unit operational. Provided estimate for replacement of condensate pump $508.93. -Meeting room split system: Maintenance declines service to system air handler. States equipment is inaccessible due to renovations/storage. -Fitness Center Split System: Evaporator severely rusted. Deterioration of evaporator coil likely to cause condensation drainage issues. Cooling temperature difference not as expected. System ~15+ yr old, R22. Recommend replacement of system. -Kitchen split system: Cleared blockage in primary drain line with vacuum at drain location under 3 compartment sink. Recomme
