Really nice tech
Khalil was super nice and he waited for me when I had customer in the office Great Worker !!!
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
Arrived to no cool on system #4 Identified clogged drain. The cause of the clog is a result of portions of the evaporator shield rusting and falling into the evaporator drain pan. While cleaning drain pan the evaporator coil shield was breaking off into the pan. Water overflowed secondary drain pan due to emergency drain on the secondary drain pan was partially clogged. Recommend installing a float switch at next scheduled maintenance
DCM2: AC complete, replaced (2) 16x20x1 filters. 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. Blew through drain line and flushed with 2 gallons of water to ensure that the drain line is free and clear because of history of clogging. Set thermostat to 78* cool.
Estimate complete
Completed maintenance on additional systems Systems 1,2,6,7,8,9,10,11,12 are 2 stage equipment, thermostat controls are for single stage equipment. Cannot test refrigerant pressures on systems because due to the inability of the equipment to achieve 2nd stage. Systems require a 2 heat, 3 cool thermostat. Switched out (11) 22x22x1 (2) 20x20x1 filters.
Arrived to office unit, ceiling was dripping with water Secondary Drip pan was filled with water but was not full enough to trip the water safety, Water was spilling at the back of the unit into the return plenum, plenum then leaked onto the ceiling Tested the drain line Identified clogged drain High degree of sludge and mud found in the drip pan along with insects inside the air handler Cleared drain line, vacuumed water from secondary drip pan and vacuumed out sludge from primary drip pan Flushed system from drain pan to where drain line exits the building Drain line is clear, system functions as designed Do to return plenum leaking water onto the insulation, the insulation has become saturated causing water to drip onto the ceiling Which will cause the ceiling to drip for a while until it dries out
System was not functioning for 2 days it came back online Friday. Symptoms of a clogged drain line tripping a water safety, checked ss2 water safety and found water in the bowl. Attempted to flush drain line and water backed up Cleared clogged drain line. Flushed drain line with 3 gallons of water system functions as designed.
