RTUi#4 -has 3 fuses missing, system is voided on R22, a leak repair appears to have been performed in the past by another company, access door covers are in bad condition, thermostat wire has exposed copper due to age, belt adjustment is needed and AX52 belt is warped which would need to be replaced, compressor is reading bad based on the megohmmeter meter, which indicates electrical failure of the compressor is expected, crankcase heaters are bad and currently are disconnected, system replacement is encouraged due to possible high repair bills. RTU# 6- has 3 fuses missing, r22 compressors reading electronically bad, one circuit is voided on R22 refrigerant, the other circuit has some R22 refrigerant but not much, major leaks are within the system. Thermostat wiring would need to repaired due to exposed

Tech inspected air handler and found no challenges, inspected spot of concern where bypass enters return and found it not sweating but may have been sweating in the past. Tech checked static pressure and found it to be testing to spec at .2 airflow and refrigerant pressures are good, drain line is not clogged and is draining properly, tech did find tenant had thermostat set to 66 and system was running continuously to try and hold temperature. Tech suspects this this is why ducts were sweating and tech recommended not setting it so low.

Performed CMA full service on 4 rooftop package units. There are a total of 7 on site, but only 4 are currently operating. Of the systems serviced today, RTU 3 is the only system with any major challenges. RTU 3 - compressor 2 on this system is shorted to ground. System is currently operating at half capacity. This will be apparent on days with prolonged heating or cooling needs. At time of testing, weather is mild and delta t is only getting to between 11-13 degrees. This is not enough temperature changeover to cope with high demand. Field supervisors office has an active proposal on this system and they are awaiting decision. All other systems tested are heating and cooling properly. No other challenges present. Note - RTUs 1,3 and 5 are not equipped with auxiliary back up heat. Filters - all filters changed and old ones disposed of.
