Performed AC diagnostic on 2014 York package unit. Upon my diagnostic employee complained that it seemed like AC was not turning on up on roof And will either maintain either 77 or go up in temperature when set to 68Â°. Upon further inspection measured refrigerant pressures on package unit and found that system was low on 410 a charge added in 3 pounds of charge And changed dirty restricted Filter that was also causing temperature Issues. Measure temperature split and found that supply was 59Â° when indoor was 77 Giving at least an 18Â° split. Upon departure system is fully operational and cooling and employee states that thereâ€™s a big difference now. Also when I was leaving the lock broke to the door where the key is located as I was trying to put it back in so I taped it on there does need to be fixed.
Performed assessment of the system for the State Farm suite. Thermostat tested thermostat and measured supply temperatures for the system at both the system and the grills, as well as the two main supply trunks in the attic space. Also measured return temps. Inspected outdoor coil and evaporator coil for any airflow restriction, replaced the filter (this was not that bad). Found small hole in the return plenum which was sealed with tape. System is cooling properly at this time. Programmed the thermostat to start cooling at 6am to 5pm mon-Friday. Set for 70 cooling and 68 heating per Maryâ€™s preference.
Inspection and performance assessment for he package unit heat pump. Measured temperature splits. Inspected motors and controls, verified refrigerant charge, measured duct temperatures at supply and return, cleaned he return grate.
