At start up the unit can begin to operate and turn off on high head pressure. Sometimes the unit resets and refrigerant pressures are normal with 10 degrees subcooling and 20-24 degree delta temperatures across the evaporator coil. The blower is operating as well as the loop pump. The txv valve fails to open or gets stuck periodically rendering the unit non operational. Customer approved the repair to replace the txv. $586 due at time of completion. I completed a parts order form. The office will reach out to the customer to schedule return. Customer asked for 08/16 or 08/17 as I explained in another form.

Unit #2 cube in the basement was not operating because it was locked out on “high pressure” fault code. Prior to finding this, I had gone into the attic and the drain switch was closed and the blower was operating sending y1 & y2 to the cube. As soon as I observed the lockout fault I called Water Furnace tech support and spoke with Mike. We spent 20 minutes running checks on the system after I cleared the fault code and the unit was operating. 3.5 psi pressure drop 11.8 loop delta .92 amp draw of the pump Discharge pressure: 232 High pressure switch was closed After running through the diagnostics, Water Furnace advised to observe the unit. The call is on record with WF. There was not enough evidence given or observed by WF to replace the circuit board. Unit operating normal. I called the customer because their spouse had to return to work while I was still on the phone. I explained as best I could what had happened and that it is not related to any maintenance or previous se

Unit #1 had faulted on “condensate” 13 times. The pan was full of water. I took the clear tube out from within the unit and used a large pipe cleaner flue brush to completely scrub the sides of any growth. The drain tubing was like brand new when I was finished. I also cleaned out the pan and blew out the pvc drain line. I reconnected everything and poured water through it to check for proper drainage without leaks. I cleared fault codes from the unit and ran the unit from the thermostat. Unit operating normal. Customer approved the repair. I asked the office to please call the customer for payment because the cellphone reception was very poor and wouldn't call out or dropped the call.

I started by checking blower run capacitor and cleanliness of the evaporator coil and blower wheel. I then went to the outdoor unit and found the fan motor side of the dual run capacitor was open. The unit most likely ran without the fan and tripped on high pressure. I replaced the voltage absorption system and then applied my refrigerant gauges and temperature probe to the discharge line. I was checking for subcooling. I did increase the indoor blower speed to high and after doing that I had normal operating pressures for r22 system with 8-10 degrees subcooling. The delta temperatures across the evaporator coil were 20-22 degrees. The suction pt was 40 degrees. The unit is operating normal. Customer signed up for service membership on the main level unit only. Customer declined adding the upstairs heat pump for the time being. Customer can always call the office and have it added for an additional $12.50 per month.

I recovered the refrigerant first then closed the service valves to keep the cube section in a vacuum. I could tell from the amount of refrigerant recovered that the unit was over charged. I removed both schrader valve stems to release residual pressure and the went into the attic and removed the txv and replaced it with brand new OEM part. I then went to the cube and pressurized the system with 325psi dry nitrogen and let it hold pressure. I then flushed lineset from high to low side. I installed new valve stems and let the vacuum pull the lineset into a <500 micron vacuum. I then added 7lb 8oz of refrigerant, a full pound less than what was recovered and then opened the service valves, properly backseating them. I then turned the thermostats to cooling mode. I had 20+ degree delta temperatures across the evaporator coil in first stage cooling mode, 12 degrees subcooling and 6-8 degrees superheat. Refrigerant pressures were great and the cooling across the coil was really the best Iâ€

I cleaned the condensate pan and drain lines and ran hot water to flush the debris and to check for proper drainage without leaks. The EAC pre filters were very clean. I operated the unit on second stage cooling mode. I reset blower speeds from 2,5,7,8 to 2,6,8,10 and informed the customer why I had made this change. I checked the electrical wiring and electrical systems, all ar within specification except for the compressor run capacitor, which was replaced. I confirmed proper flow rate and heat of rejection and then pressurized the ground loop to 65psi. Unit operating normal.

Txv in the attic is not opening properly and causing the head pressure to build up and turn the compressor off. The unit is cooling as I checked it the other day, 4psi pressure drop and 10-12 degrees heat of rejection. The refrigerant is restricted at the valve. The valve needs to be replaced. I made an estimate for the work and completed a parts order form estimate with pictures of the Lennox evaporator model and serial number and a picture of the part number on the valve. Customer tried to reach their partner to discuss but they were unavailable. I told the customer that diagnostic charges paid today could be credited toward the repair.

Replace controller board in the cube unit #1. I replaced the control board and operated the unit on second stage cooling mode. I went into the attic and cleaned the drain line and ran hot water through it to flush the debris and to check for proper drainage and pump ejection. I replaced the upstairs filter with one provided by the customer. Unit operating normal. Customer paid $300 deposit which is not showing up on the invoice. Customer has paid the repair in full. The office will have to correct this invoice.

Donna was supposed to have gotten re approval for the repair from the customer. Customer gave me approval the night I was here fixing refrigerant leak but I guess the estimate was not signed. I am pretty sure it was signed. I went over the repair and part credit with the customer. Customer still is entitled to refrigerant credit from all repairs and labor allowance for this repair. Customer spoke with Darlene regarding finding out the labor allowance but never got an answer. Customer not here now and wants to pay through the office in the morning. I replaced the compressor and refrigerant filter drier, flushed with nitrogen and pressurized the system to 250psi. There are no leaks. I vacuumed to 500 micron and charged the system. Unit operating normal.

I performed the maintenance on the hydronic system and switched it from heating to cooling mode. I cleaned the condensate drain line and ran water through it. I pressurized both ground loops and checked the electrical wiring and electrical systems, all are within specification. Unit #2 is operating normal. Unit #1 is the geo split system with the cube in the basement and an air handler in the attic. I operated it on cooling mode and the loop pumps never got powered from the relay inside the unit. The fuses are in tact. The control board is malfunctioning and needs to be replaced. I completed a parts order form and customer paid 300. Need to clean the drain upstairs and finish maintenance on this unit when we return. I checked the electrical in the basement but not in the attic.

Leak search and repair and charge unit with 8+lbs of r410a refrigerant. I fixed the leak on the suction line near the service valve. I installed a new filter drier, flushed system with dry nitrogen after pressure testing. Pulled into a sub 500 micron vacuum. Charged the system with 9lb 8oz of refrigerant, 15oz more than factory charge to compensate for long lineset length. Went to test the unit and the compressor runs but does not pump the refrigerant. The compressor had to have been damaged while operating with loss of charge or low charge. I tested several times and each time is the same. No difference in high and low pressure, the compressor has a grinding noise as well. There was no way to test the compressor with the system being flat on refrigerant. I completed a part order form for the compressor. The office will need to contact the customer for scheduling as soon as possible.

Customer has 3 units. Unit #1 is a geo heat pump with gas furnace used as auxiliary heat. The gas furnace is operating normal. All components on the geo heat pump are working correctly but the unit has low delta temperatures in both heating and cooling and high Superheat. The unit has lost several pounds of refrigerant from a defective valve stem. Refrigerant oils accumulated under the service valve. Replacing this stem while the system is still under pressure and recharging will have this system operating normal. Unit #2 has lost all its refrigerant charge from a leak in one of the joints inside the geo cube. A leak search would need to be done to identify the leak and then fix it with brazing, replace the filter drier, vacuum the system and charge with 8+ lbs of r410a refrigerant. The auxiliary heat is the only working part of this system. The compressor will not run because the system has no refrigerant pressures. Fixing this leak should fix this unit but the geo heat pump heatin
