Really nice tech
Khalil was super nice and he waited for me when I had customer in the office Great Worker !!!
DCM19: Heat complete, completed remaining 8 systems. Replaced (3) 22x22x1, (2) 20x20x1, (2) 16x20x1, 14x14x1, and 20x24x1 filters.
DCM2: Heat complete, replaced (2) 16x20x1 filters. Found system #1 outdoor capacitor was low on compressor side. 35/5 reading 30.2/4.8. Replaced dual capacitor and tested operations, compressor amp draw went from 8.3 to 7.6 after replacing. Capacitor is operating properly. Both systems are fully functional and operating within manufacturer specifications at this time. Refrigerant pressures and temperatures are appropriate for indoor and outdoor weather conditions. Maintenance checklist attached. Set thermostat to 64* heat.
DCM19: Completed 11/19 systems, will need to return to complete maintenance on systems 11-16, 5,19. Completed maintenance on systems 1-4, 6-10, 17, 18. Replaced filters (9) 22x22x1 (2)20x20x1. All systems other than #2 are fully functional and operating within manufacturer specifications at this time. System #2 is throwing a fault code for emergency heat had to adjust configuration for the kw from 25kw to 5kw, heat strips were rated for 5kw. System is now functional and operating within manufacturer specification at this time. Placed thermostats to 64 degrees heat. Maintenance checklist attached.
System#4 in c bldg does not have water safeties, I recommend adding. Also old R22, recommend replacing. Did Heat maintenance on units 4,5,8,9,10
DCM9: Heat complete, replaced (6) F20x25x2, (4) F16x25x2, (2)F20x35x2, (1)F20x25x1, (2)F20x20x2, (1) F20x20x1 filters and replaced (1) AX35, (1) AX32, (1) A48, (2) A55 belts. System 1- Arrived to fuse blown. Ohmd through motors and compressors and could not find reason for blown fuse. Replaced 50amp fuse and tested system, system is now operating within manufacturer specifications. System 5- Fails to heat. In first stage of heating heat sensor opens after 10 seconds of run time. In 2nd stage heat the contactor fails to close while having 24v only letting one leg of power through. System 7- still has a failed compressor diagnosed in previous visit. System 8- still has a failed compressors diagnosed in previous visit System 10- Fails to heat. In first stage there is an open circuit inside of the heat strips that is unrepairable and second stage has been unwired due to previous failures. Will need to replace heat strips for system to heat. All other systems are fully functional
Office closed until 1pm
DCM1 complete; Heat; (1) F16204 checked. System is fully functional. All components are operating within manufacturer specifications. Refrigerant pressures and temperatures are appropriate for indoor and outdoor conditions. Heat checklist attached.
Installed digital thermostat to replace mercury thermostat. Set to Auto ( Heat set at 62, Cool at 78 ) Tested system in Heat, Cool, Em Heat and Fan mode. Functions as designed. Fabricated thermostat lock to fit over thermostat. Photos attached
Arrived to No Cool and water Maintenance was conducted on the original (6) units Jun 4, only the new building had maintenance done in Aug. AHU #14 ( 478B ) : System had a tripped breaker. Tested system in Fan, Cool and Electric Heat. All amp draws were within design tolerances as well as capacitance. Couldn’t get system to fail, system is cooling at this time AHU #15 (476, behind rolling door ) : Identified clogged drain line and cleared. System has no emergency drain pan or safety switches. Installed SS2 safety to prevent damage to adjacent units. Photos attached Closed out with on-site manager
Arrived to report of No Cool When I arrived, system was running. Tested system multiple times, every time system function as designed. Diagnostics photos attached. System utilizes a mercury style switch to control the thermostat. It’s not as accurate or as sensitive as the new digital style. Spoke with manager on site
