Replaced supply and return plenums. Installed 3 new EWC dampers. Replaced all flex lines from supply plenum to trunk lines. Did a retest on zoning for new dampers to ensure correct operations. Tested system operations.
2 system heat maintenance. Checked blowers, inducers, ignitors, all within manufacturer specs. Cleaned flame sensors, checked all water and heat safeties all working correctly. Scoped both exchangers no visible deterioration. Drains are clear, changed both filters. Both systems are operating correctly and efficiently up departure.
Finished Changing remaining filters on units #4,6,7,8 and 9.
Need to return to change filters on System 4,6,7,8 and 9 Systems 6-9 are fully functional. All components are operating within manufacturer specifications. Refrigerant pressures and temperatures are appropriate for indoor and outdoor conditions. Systems 2-14 do not have the ability to operate supplemental heat ( heat strips ). System are wired using 12 awg conductors with a 15 amp breaker in electrical room. Heat strips are not connected and should remain disconnected due to available conductor size.
Helped mason with maintenance on systems 1-5, 10-14.
DCM14: completed 10/14, replaced 18x21x1 filters in 1st and 3rd floors. Need to return to complete maintenance on systems 6-9. Heat strips are not energizing in emergency heat, need to get a senior tech to look at the heat strips on all systems. No issues found other than heat strips.

DCM14: completed 4/14. Need to return to replace filters and complete maintenance on remaining systems. Filter size- 18x21x1. Systems 5, 12, 13, and 14 are heating at this time tested refrigerant pressures in cool due to outdoor ambient being 70*, refrigerant pressures and temperatures are appropriate for indoor and outdoor weather conditions. Thermostats were set to 1 heat stage not allowing the heat strips to energize programmed thermostat for aux heat. Will need to test heat strips when return. Set thermostats to 64* heat. Left early due to business closing for holiday.
Arrived to doors off the system and thermostat set to off. Put thermostat into heat mode and pushed in furnace switch. System started heating spoke with homeowner and he mentioned that the door didn’t seem to be on properly when he removed it. Taped furnace switch down and put doors on properly. Offered homeowner a maintenance plan and he declined at this time. Informed homeowner if he were to need us to come back out it would be another $75 service call.
Water leaking from 1st dehumidifier - issues found: All filters are dirty All aux. drain pans are too short (dehumidifiers are longer than the drain pans) will leak to the floor is any issues All drains are improper and need p traps installed Removed all filters except one as the original installation does not allow for removal of filter (need to correct) Manager left for lunch
