DCM2: AC complete, homeowner recently replaced filters, gave homeowner 16x20x1 filter however did not have a 20x20x1 will need to bring an extra when we come out for heat maintenance. Upstairs system is fully functional and operating within manufacturer specifications at this time, refrigerant pressures and temperatures are appropriate for indoor and outdoor weather conditions. Mainfloor system is cooling at this time however is not operating within manufacturer specifications due to system being low 2-3lbs of R410A. Noticed P-traps were not insulated and suction line was missing a piece of insulation, insulated P-traps and suction line. Photos and maintenance checklist attached.
DCM2: AC complete, gave homeowner (1) 14x14x1 and (2) 14x20x1 filters. Systems are fuller functional and operating within manufacturer specifications at this time but due to age of system’s multiple part failure is possible at anytime. Refrigerant pressures and temperatures are appropriate for outdoor and indoor weather conditions. Photos and maintenance checklist attached. Upstairs indoor capacitor was low 5+-10% reading 3.4 homeowner decided to go ahead and replace today.
Moved 2 supply vents and 1 return vent into upstairs classroom/office
Scott has had issues maintaining a comfortable temperature in his office upstairs - came out to inspect situation as 2 other service experts have been out and deemed no issues - upon arrival temperature was set to 68* on the thermostat and holding 73* on an 85* day - checked blower speed on Trane air handler and is set to low speed for max. Cooling temperature through the supply vents - inspected cooling coil and filter (clean) - pulled attic staircase down to inspect attic - found approx. an 4’x8’ drywall missing any kind of insulation at pulldown staircase (prior drywall repair in ceiling?), under the main round metal duct approx. 2’x10’ no insulation of any kind (maybe not insulation ever from build time?) - found some bat insulation to be R30 and some is R13 - Office only has 3- 14x6x8 supply registers for 1.5 tons of cooling and 1- 14” low return duct - the ledge where the false blue doors are 2- 14x6x8 supply registers for 1 ton of cooling and 1- 14x6x8 high return duct - connect
DCM2 complete; AC; (2) F16251 replaced. Systems are fully functional. All components are operating within manufacturer specifications with exception. Refrigerant pressures and temperatures are appropriate for indoor and outdoor conditions. AC checklist attached Main Floor blower motor capacitor is outside of manufacturer tolerances 20 mfd measuring 13.3 mfd. Will have to return to replace capacitor, do not have a 20 on the truck
Arrived to thermostat at 71 reading 71. Refrigerant pressures and temperatures are appropriate for indoor and outdoor weather conditions (photo of pressures attached). Amp draws are in range. Temperature split 20* (should be between 15-20). Checked supply air from all supply vents to ensure air flow from every supply. Checked thermostat to make sure there wasn’t a temperature display offset, there is no offset. Temperature difference from outdoor air to indoor air should be 15-20*, talked to worker at the desk he said yesterday the thermostat was set at 71* reading 74*, looked up temperature from yesterday it was 93* meaning we are getting a split of 19*. System is cooling at this time.
Arrived to No Cool / Water overflowing pan Identified broken PVC drain and the pan full of water. Water safety was on the side of the pan that was somewhat higher than the side of the pan were the pump sits and wasn’t turning off the system due to water level not getting high enough on that side of the pan. Removed all water from pan, repaired drain line and moved water safety to lower side beside the condensate pump. Photos attached System is fully functional
Identified clogged drain at indoor, cleared drain line and vacuumed water from pan. Tested system, functions as designed. Refrigerant pressures and temperatures are appropriate for indoor and outdoor conditions.
