Air Conditioning System Maintenance Service. Performed semiannual maintenance on two cooling systems. Inspected all Performance, Mechanical, and Safety Systems. Verified everything was operating within the manufacturer’s specifications for operation. Outdoor condenser refrigerant pressures are within range and condensers clean. Indoor system drain lines cleared and treated. Filters are dirty, but the homeowner did not have replacements. I advised them to replace them ASAP. I noticed that the westside unit’s condenser fan motor is showing signs of overheating. We have added UV lights to the downstairs unit but not the upstairs unit. No other major issues found. I recommend that we replace the fan motor and add UV lights to the upstairs system. The homeowner would like to have the fan motor replaced today but did not want to add UV lights at this time. Fan motor replaced and both systems are operational.
