4-15-24 Warranty call Dining room AC systems were not keeping up this weekend. I found the center system number one condenser service disconnect was in the office position. The outer system the control wire to the compressor contactor was disconnected. I turned disconnect on and reconnected to wire systems are both working Not really sure how either one of these items happened. However, I’m the only one working on these units now, so I’m gonna put this down as warranty

3-19-24 Kitchen, air conditioning units installed low ambient with pressure, transducer and one compressor contactor Removed the existing mechanical low ambient control units and installed electronic variable, speed controllers The old controllers were slamming the motor off and on too quickly, causing motor failure and fan failures.

3-15-24 Picked up low ambient kits to put in next week

3-12-24 Kitchen AC system repairs # 2 condenser unit. Removed existing compressor found short ground last week. We did test the oil checked out Ok We also use dry nitrogen to blow out the line set into the evaporator to confirm that the TXV is not clogged. Today we installed new 5 ton compressor, liquid line dryer, and also added some acid away. Tested the system with dry nitrogen or any leaks no leaks. Evacuated the system to 500 microns Added 8 pounds of R410a Part of today’s job was to install head pressure control both kitchen AC condenser units. Both these units are microchannel condensers, and the sensor on these units will not work properly. I need to pick up a different controller and sensor and then installed them later on. Ordered the correct head pressure controls. They should be on Friday or they will be on a separate ticket.

Went over a new zoning system. Waiting on a email with a quote from C.D. Jones to build a estimate for this job

3-8-24 Tyler and I got information to install zoning system at the churches offices

3-8-24 Today to install headmaster controls on the kitchen condenser units One of the condenser units we found out has a short to ground compressor. We did not install the headmaster controls today gonna work on the compressor

2-20-24 Jon and I made the following repairs Jon installed the condenser units motors on the kitchen AC and dining room AC condenser units. I installed a new thermostat on the bar beer reach-in cooler, I did test the existing thermostat it would not open and tested new thermostat prior to installing. If there is still an issue with the box, getting too cold, we’re gonna have to dig into a little deeper. Walk-in freezer condensate line has frozen up. The condensate pipe does have a heater that has failed. Remove the failed heater and installed self regulating heater and reinstall the existing arm cell insulation. I don’t have access to the parts. They are on a different job number.

2-20-24 Today’s visit was a check the basement twinned furnaces that were tripping off. Furnace #4B did have a bit of a delayed ignition ignition rod is a generic unit Reinstall the 90% burner cover properly and then tested. The system seems to be working at this time. Furnace #4A found the electrical connection on the flame sensor, disconnected and also the pressure relief on the pressure switch tubing was disconnected. Reconnected to tubing. System is working. Also, we did find the blower speed and heat. We’re on two different settings. Currently they are both on the low setting. The Furnace # 1 Also found the pressure switch tubing to the inducer motor was disconnected. Once we plugged it in the furnace worked fine. Speaking with Al these were the only systems that seem to be not working properly. Any other areas are working properly we can always come back out and check them. No parts were used today.

Replaced the condenser fan motors on the west and east condensers in the line of 6 condensers on the roof. The harness plug was removed on both units and the new motors were directly wired, The east unit does have a low ambient kit that has been left in the motor circuit. While replacing the east unit’s motor I discovered that the fan blade has a hub that is starting to have some play in it. I do recommend replacing the fan blade to prevent an unplanned outage in the future. The fan blade is okay today and I left the unit running since it cools the kitchen. Tech notes: West unit, York, YCJD60S43S4A, s/n W1G6782381, new motor amps 1.27a (rated 1.3a), new capacitor 5.03uf (rated 5uf), East unit, York, m/n YCJD60S43S4A, s/n W1F4804206, new motor amps 1.24a (rated 1.3a), new capacitor 5.02 (rated 5.03). I will add more notes later

2-16-24 Picked up two condenser fan motors, Electric heater for the freezer condensate line Temperature control for the reachin cooler On Tuesday morning make repairs

2-15-24 Perform equipment survey there are multiples split systems. They still need to get them model serial numbers to Rick. I’m going to do that first thing in the morning on a different dispatch.

2-15-24 Made repairs to the dining room condenser unit installed new condenser fan motor. Also did check the reach beer cooler. I need to get a thermostat for that and I need to get some parts for the walk-in freezer.

2-13-24 Condenser fan motor for Thursday morning’s job

1-17-24 Beer reach-in cooler not working. Found the condenser fan motor was bad,picked up new fan motor and installed. Unit is working. Compressor is extremely hot. May take overnight to completely cool the box down. System on the south perimeter area in the dining room thermostat reading 66° and it said it’s 69° Check the twin furnaces. Also are working properly. Rise it is at 50° it’s right between 25 and 55 Supply is 135° return is 85° The thermostat for the perimeter system is against an outside wall. When I remove the thermostat from the wall there is some insulation back there. There’s also a breeze coming through. I use some foam tape to isolate the thermostat from the breeze. The center dining room system getting the same temperatures Coming out of the registers is 120° Upstairs by the beer kettles the temperature is 81° Dining room area has extremely high ceilings, most of most of the heat is going up in the ceiling. We need to get some kind of fan system set up to blow

12-28-23 The beer kettle chiller system is not working and not maintaining temperature. I was here yesterday. The system when I left was working, but in the morning was not maintaining temperature. Today I found all the controls reset at 78 and the temperature the kettles were 78° We lower the settings to the four kettles down to 33° which is normal. The chiller system is running, unit ran for approximately two hours. My temperatures are dropping on all four kettles. Why the unit was running I checked my refrigerant charge. I am maintaining 15° subcooling and also I have 10° of superheat. I checked the glycol level of protection, we have protection down to 0°F I checked the circulator pump. It is maintaining a pressure through a pressure regulator of 10 psi. I did not find any air in the system The Pump up on the roof. It has two heat strips wrapped around the pipes. One of them, I don’t think it’s working. Both are real old and should be replaced. I spoke. I spoke to Mark abou

12-26-23 Glycol system, not working for the brewing area kettles. Found the condenser unit and pump system does have a flow switch that was open. There may have been some air in the system, causing the flow switch not to close, but we did manipulate the valves, a little bit open and closing, and the flow switch did close. If this happens again, we may have to go a little deeper into the system. Currently, the system is working.

12-14-23 Gathered information to bid replacement of the 5 ton RTU with a larger tonnage unit if possible. E-mailed info to Rick

11-15-23 Return visit to make repairs found last week. Dinning room, upper level HVAC system Left side twinning York furnace serial W1G3889196 Install new blower motor, run capacitor. Installed new control board. Ran and cycled the heating system working at this time. Kitchen, HVAC system Twinning system condenser unit York serial # W1K4104378 Installed new condenser fan motor, with new run capacitor. Install new fan blade. Tested motor and fan blade for proper operation working at this time. Condenser unit does have a condenser fan cycle control,that was disabled. I reconnected fan cycle control. (CI 400psi, CO 300 psi) The unit is working at this time. The other condenser unit for the kitchen I installed a new fan cycle control. And set it the same as the other This is a twinning system. In the attic area near the furnaces, there is no designated combustion air, However, there is ductwork in an outside vent for a combustion air that has been capped off. I installed two registers

11-14-23 Picked up material for tomorrow’s repair

11-9-23 Tstat is not working correctly Spoke to John Paul he directed me to the corner office, were the thermostat was reported to be not working. This thermostat is an older Honeywell probably 1982. It is holding it’s programmed. Also when I went to the air handler above the ceiling. The damper control did have the AC damper in the open position. The office what is it about 78° The air handler above the ceiling. The chilled water pipes were warm and also the hot water pipes were also warm. The return at the air handler was 80° and the supply was also 80°. We’re down to the maintenance shop I wanted to mechanical room Found the chiller system is shut down, and the cooling tower is also been drained. The 2 Lochinvar boiler’s one is in standby, the other is turned off. The AC system is completely shut down the boiler system has one boiler in standby potentially because if we have a extremely low temperature at night There is potentially one way of getting cooling in the building from

11-9-22 Performed heating check out Turn on the outer perimeter heating system one of the blower motors is not working and also the board is burnt and also tripping the circuit breaker. We need to add a combustion air vent on the old existing system. There is no dedicated combustion air in that upper space. Also found on the kitchen system AC system. The fan cycle switch has been disabled, and one of the fan motors has a bad bearings and also the fan blade hub is loose and causing the fan to wobble. I will locate these parts. They will go back up and install. I have a list of parts on my person

Thermostat is working as it should, they are wanting a new system to get away from the old boiler and chiller system they currently have. Informed Deanna. All is working as it should at this time

10-20-23 The pizza prep cooler is not working AdvantEDGE Model# SMP27-12 Serial # SMP27-12-12080016 Their was no power to the compressor. It looks like someone had rolled over it with one of the wheels. Which unplug the connection. I plugged it back in waited about five minutes with a call for cooling. The compressor never came on, but the evaporator fan did. The OEM start components they are very expensive and would need to be ordered. Decided to check the compressor for shorting grounds and then install a 3n1 start relay kit which would match the horsepower (1/5)hp for this unit. The compressor checked out fine, install the hard start kit. Unit is working at this time. While on site I could hear a fan blade hitting up on the roof. It was the kitchen exhaust fan. Mark and I made some adjustments to the alignment of the shroud and the wheel. Stopped the clicking we’ll see how that goes.

9-12-23 Installed hose bib in the upper area near the water heaters, right below the access to the roof. Ice house- Right side evaporator,replaced the left side evaporator fan motor. Tested for proper rotation an operation. Evaporator motor was charged in a previous ticket. I just installed it today. June 21 2023
