A braze joint on the txv that was replaced with the air coil did not hold and began leaking. I brazed, pressurized with dry nitrogen, vacuumed and charged to factory specification. Repair covered under warranty from previous repairs.
I confirmed that the air coil was leaking from a place that could not be repaired. I then evacuated the refrigerant and nitrogen and removed the air coil and biflow filter drier in the cube. I reused the cooling txv at the new air coil. Brazed all fittings and then brazed in replacement filter drier. I used 350psi of dry nitrogen to pressure test the system for any leaks. I let it hold that pressure for 15-20 minutes while I began packing some tools away. I then used the nitrogen to flush the lineset. I called WF to ascertain the total weigh in charge. I weighed the charge in and let the unit operate for 15 minutes before adding more refrigerant to obtain normal refrigerant pressures, 25+ degrees temperature rise across the air coil and normal heat of extraction. The new coil was sent under pressure and retained that pressure until released. The whole system was pressure tested and there are no refrigerant leaks. Unit operating normal. Customer paid remaining balance. Niko has the o
Up on arrival found system was low on refrigerant. Performed PRESSURE NITROGEN LEAK SEARCH and bubbles soap . Could see anything. Used electronic leak detector found A coil is leaking.
Service call on 11/23/19 On arrival the geo cube has error codes low pressure checked electrical connections checked compressor capacitor it was below spec so I suggested replacing now to avoid future problems I gave quote for customer before I go the next step I replaced the voltage absorption system rewire start up checked vs pump checked EWP and LWP also water temp I checked pressure and temp and unit has leaks the pressure is 0 degrees I suggested nitrogen pressure test to find the leaks and repair I gave Option for the customer accepted I we have to come back to finish the job bc I don’t have enough nitrogen and bubble soap. for voltage absorption repair on C.C on file. Customer schedule for Monday between 12 to 4
I recovered remaining refrigerant. I removed the leaking air coil, txv and refrigerant biflow filter drier. I set the air coil and brazed in the new txv and the lineset. I ran drain line again and sealed the unit up. I replaced the biflow filter drier in the cube. I replaced valve cores in the service valves. I used dry nitrogen @ 300psi to check for leaks in the joints I brazed and the rest of the system. The system held that pressure for 10-15 minutes while I called WF tech support to get the weigh in refrigerant charge. I let pressure flush out the lines and then pulled a <500 micron vacuum on the system and then added 8lb 2oz of r410a refrigerant to achieve 10 degrees subcooling and 20+ degrees delta temperatures across the evaporator coil. System has no leaks and the unit is operating normal. Customer paid remaining balance and the job now has been paid in full.
I performed an electronic leak search and found the refrigerant leak fairly quickly. I called Water Furnace to get a case number and part numbers. I took $59 off because the customer paid it yesterday. Customer paid for leak search and then paid $700 deposit for coil replacement. I completed a parts order form.
I found unit low on refrigerant. I wrote up all estimates and explained to the customer what each one involved. I found evaporator coil frozen over and we will need to return to leak search. Customer asked me to leave the blower panel off so that it may thaw more quickly. I will put a customer follow up for in the morning. I will also let the dispatcher know. Also customer was there with me when I pulled the blower cabinet off and we both saw the bottom piece of insulation was pulled up close to the bottom side of the blower wheel. Customer pulled this out themselves. I do not believe this was the cause of the freezing up but it contributed to it certainly.
Up on arrival installation of the flow center removed defective flow center, installed new flow center, flushed the loop . Checked operation, unit operating at this time
On arriva found system cutting off on high pressure.found air in the loop .also found flow center leaking .system is operating at this time but we need to replace flow center .2 tech needed .customer signed up for membership.customer paid $801
Upon arrival I was told top floor unit wasn’t working at all. Found capacitor with 0mfd rating, top puffed up, coil broken. Replaced with new and tested. Unit still covered under parts warranty. Restarted and tested unit. Measured amp draw, delta air temps, and delta loop temps. Unit operating normal.
Customer wasn’t home, was given door code. Upon arrival I went to first floor unit and removed all refrigerant. Replaced bad txv with new one. Pressurized unit to 350psi nitrogen and checked for leaks. Pressure held, no leaks found. Removed nitrogen and vacuumed system down to 500micron and held. Added factory charge of 11.6lbs of 410a then returned power to system and ran ac. Checked Superheat, subcool, and delta air temps. Unit is operating normal. Then I went to each thermostat and replaced the Nests with Honeywell T6 WiFi thermostats. Configured thermostats for dual fuel operation where Gas Furnaces are enabled at 40 degrees and Compressor Lockout is enabled at 35 degrees. Set all schedule periods for 78 cool 68 heat until customer sets up their own program. Left thermostat boxes on dinner table with Nest thermostats inside each box. Also included in the box is the WiFi setup booklet. WiFi needs to be setup by homeowner, I cannot set this because customer needs to use their own e
Complete quoted work to add refrigerant and leak sealer
Upon arrival I was told that main floor HeatPump wasn’t working, only gas heat. During diagnostics I found HeatPump locked out on High Pressure, found previous faults were all the same. Reset fault and ran system. Refrigerant pressures and temps are fluctuating. Need to replace TXV, before doing so we need to weigh out charge, then repair, vacuum, and add factory charge back. Informed customer. Office please follow up with status of part. Ideally we would like to return when outdoor temp is above 50.
