arrived at customers, location signed ourselves in the beginning, getting set up for compressor replacement. Recovered all refrigerant from the system into the recovery cylinder. Removed failed compressor and filter drier along with compressor plug and dots sensor. Installed new compressor and filter drier. Pressurized system for leaks and held 275psi for 30min. Pulled system into a deep vacuum and let sit in vacuum while installing other new components. New compressor required 80/5/440 cap replaced with truck stock and added to invoice. Weighed factory charge in the system and turned system on in cooling mode. Set refrigerant charge to manufacturer specifications 105/274 sh16 sc17. Confirmed drain was clear and returned system to service
Route to the customers location greeted the lady in the front office. Started troubleshooting at the thermostat. Turn system to cool indoor unit is running filter clean coil clean, blowe amps within spec. Went to the outdoor unit Confirmed was running. Took amp draw of the compressor pulling 12.2 A. Found over 200 psi pressure on the suction with 300 psi on the discharge. Tried pumping system down to test compressor got to 155 and stopped. Compressor internally failed and need’s replaced. After hrs office will need to get with Mike on pricing and availability once able to talk to manufacturer. Started a incomplete estimate for compressor repair.
Arrive to commercial location with the signing at the office and met with Mike. Mike took me over to where the chillers are talked with Mike about what he was looking for out of today’s visit customers interested in getting a second chiller operational took pictures of known good unit to compare to chiller that has been pirated, after speaking with Ryan G on the phone will get together Monday morning to discuss next action moving forward for quoting the customer for repair. Also, customer might be interested in getting several other chillers looked at that have been down for several years. Return the system to service.
Arrived at customers location met with maintenance manager. Showed me where all the equipment was to begin troubleshooting found no low voltage car coming to the outdoor unit. Traced back to a bad cooling relay in the thermostat. Replace thermostat got system up and running confirmed refrigerant levels, 115/260 recommended to customer having contactor replaced also completed all repairs while on site and return system to service.
I completed a complimentary refrigerant leak search on the system. No leaks present at this time. All wiring is tight and in good condition. Tested the systems operation between heating and cooling. The Contactor and capacitors are in good condition. The refrigerant pressures are in correct range per manufacturer specifications. The system is working properly at this time. I completed the check sheet and emailed it to the customer.
Upon arrival checked filters. Spoke with customer and explained what I would be doing today and that I would need to see each vent today. Thermostat is clean, April air stat, and it is level. Turned system on heat to 76°. Went into basement to evaluate the indoor unit. The coil is clean, along with the blower and found no leaks coming from the coil. Wires are all tight. Cleaned ez trap. Heat strips amped within specs. Blower amped at .6amps. Duct is clean and tight. All low voltage wires are tight. 131° air temp coming out of vents, 72° entering. Went outside and evaluated the unit. Coil is clean. Wires low voltage and high are all tight with no burn marks or broken. Contacter is working well, no burn marks. Capacitor is 45/5 and is a 45/5 mfd capacitor. Fan motor amped at 1.1amps and showing no signs of oil leakage at this time. Compressor amped at 5.3amps. Refrigerant levels where found at 128/371. Let system run awhile, and system is working well at this time. System is set fo
Carrier heat pump system just inside of the office when you first enter. I found the blower motor and module shorted causing the system to freeze. The fuse mount in the airhandler is saturated. It needs new 60 amp fuses as they are cracking. The mount needs dried off. Recommend replacing the mount and fuses. The evaporator and condenser coils are dirty. I completed a complimentary refrigerant leak search on the system. I found a refrigerant leak in the suction service valve. The compressor meghommed green (good). The 1 pole contactor is pitted. The 60+5 capacitor is weak at 55. The system is low on r410a refrigerant. I called carrier for price and availability on the parts needed for the repairs. The repair quote will be sent for review.
Upon inspection found first chiller with a water leak from Y brass fitting on the supply side. This fitting needs to be replace. On the second chiller found system flat completely out of refrigerant R410A A leak search with nitrogen boost is need to find leak. Also we will need 9 pounds of R410A to be able to fill system per manufacturer specs. Both chillers are off at this time , this is the way I found them upon arrival.
Cooling inspection HP AHU Inspected high and low voltage wiring, all electrical wiring is intact and tight at this time. Inspected evaporator coil , coil is clean and free of debris at this time. inspected blower motor, housing and wheel, all is clean and working properly at this time Blower motor is pulling 1.04 amps at this time Delta T is @50.80F at this time Static pressures 0.41 inWC and 0.04 = 0.44 delta P inWC at this time Motor is spinning freely at this time Inspected cabinet for cleanliness, cabinet is clean at this time. Clear drain line, drain is clean at this time. Inspected air filters (1) 20 x 20 x 1 filters is dirty at this time. Customer will purchase and install it . HP Inspected high and low-voltage wiring, all electrical wiring is intact and tight at this time. Inspected 0FM, motor is spinning freely and operating properly at this time. OFM is pulling 0.49 amps at this time. Inspected run capacitor 45/5 -/+6%, capacitor is working within range at this time
Chiller inspection. Inspected the outdoor chiller. Found the three pole contactor pitted. Recommend replacing. The condenser coil is dirty. Recommend cleaning. Repaired the one wire at the compressor that was melted and missing the jacket. Ohmed the compressor came back in the green, the pipes are broken. They said they will repair them. Checked all the fuses in the system. All are good. Pushed the contactor in to test operation. The chiller inside is completely empty of refrigerant and there’s water in the line set. The office is making an appointment for Shane and Ryan to return to go over repiping for the system.
