I called W.F. to verify operating specifications. Superheat 12-14, subcooling 10-14. Suction: 125 discharge: 335. 16 gpm. 95 ewt, 87 lwt, 30psi ewp, 24.50psi lwp. Return air temperature 74, supply 55-56. Heat of rejection 62,000-70,000 BTu/hr with eat correction factor. Unit operating normal to specification verified by W.F. I set zone control to allow second stage operation when only one zone is calling and I adjusted the weight on the blow out damper. I verified 55 degree supply air going to the master bedroom. I found no faults. That is not to say something did not happen and hopefully it doesn’t again. If something else occurs it will please call. I spoke with the service manager and was given the ok to write this call up under warranty.

The unit had lost most of the refrigerant charge. It had leaked out from 1 of 4 service valves. I tightened all schrader valve cores and installed new brass caps with rubber washers on 1 set of valves and on the other set I applied mechanical leak proof caps. I called Water Furnace and was given the total system charge of 127oz. I charged the unit with 7lbs and then operated the system and added more refrigerant to achieve 14 degrees subcooling and 6-8 degrees superheat. I went into the attic and had 80.2 return air temp and 59.4 supply air temperature. I checked pressure drop of the water loop and heat of rejection. Unit operating normal.

Upon arrival I was told that geo system wasn’t keeping up at all. During diagnostics I went to condenser cube in basement and found suction line frozen. Went to attic and found entire Evap coil frozen. Checked airflow and found all dampers are open. Need to return to diagnose frozen coil. Customer asked for first apt tomorrow.

Upon arrival I was told that system wasn’t keeping up during warmer days. I read notes of previous service calls and spoke to customer about them. Per customer ac has never been a problem, but when pm was done in spring he started noticing the system not keeping up. Per notes, fan speed was decreased, and I found it was on the lowest setting, changed back to default. Was 975cfm now 1225cfm. When inspecting AHU I found txv sensing bulb was still zip tied to the side of the coil and not on suction pipe. Shut off unit, removed all paneling, and installed txv sensing bulb on suction line for proper metering of refrigerant. I restarted system and called for ac. Found normal refrigerant pressures and temps. Normal water flow rate and heat rejection. Normal amp draw of compressor, blower, and loop pump. Also found no faults on aid tool. Called Alex and informed him of what I found and he also spoke to customer.

Replace left side loop pump. After I replaced the left side pump and pressurized the ground loop and burped the pumps I operated the unit. 74,000 BTU/hr heat of rejection, 12-14 degrees subcooling and 8-10 degrees superheat. 18-20 degree delta temperatures across the evaporator coil. Loop temperatures are no longer increasing with adequate wate4 flow returned.

Upon arrival I went to unit and verified all refrigerant is out of system. Used tube cutters to cut out txv. Cleaned piping with sand paper and piped in new TXV. Brazed in both sides as well as equalizer tube. Did not remove entire tube, used coupling because of limited access. Pressure tested to 400psi nitrogen and held. No leaks and both sides equalized. Removed nitrogen and pulled vacuum to 500micron and held. Vacuum held so I added factory charge of 93.0oz of 410a. Returned power to the system and ran ac on both stages from aid tool. Verified normal refrigerant pressures and temps. Shut off system and then ran ac again from thermostat. Verified same pressures and temps. Unit is operating normal at this time.

Upon arrival we spoke to customer and he explained that system faulted the other day and hasn’t come back on, error code on thermostat. Went to system and found it faulting on low pressure. Reset unit and fault immediately appeared. Put gauges on system to find it flat. Found some oil in system but used nitrogen to trace leak. Found leak at txv and cannot he repaired. Txv needs to be replaced.

Reconfigure system to operate as intended. The primary issue had to do with dehumidication being set to 42%. This was causing the unit to decrease the blower speed to 1, its lowest and slowest setting in an attempt to satisfy the set point, which it could not do. I called WF tech support to ask what is the best setting, 55%, which is what I set it to. I also set blower speeds to factory specification in both heating and cooling modes. I pressurized the ground loop to 65psi and set the flow rate and checked the heat of rejection. The unit is operating normal. I did show the customer the only manual damper that could potentially be adjusted to increase airflow to the upstairs and we closed it some of the way. I advised customer to lower the thermostat set point for downstairs to see allow upstairs to cool down more. I did confirm airflow and cooling through several upstairs vents. Unit operating normal. Customer signed up for service membership. I was able to waive the dispatch fee and

Upon arrival I was told that rear office ac wasn’t working, same unit they had a problem with a few weeks ago, thermostat blank. Was shown to mechanical room on 2nd floor where I found emergency pan full of water. Removed water with vacuum and restarted system. Could hear a little resistance in blower so I opened up panel to find entire section of blower section insulation had peeled. Used Sure Stick adhesive spray and secured insulation back onto panel. Ran ac and found system running in 1st stage. Compressor is single stage so I changed indoor wiring to run at 2nd stage, raised cfm from 1200 to 1800. Original delta air temp at Evap coil was 28, now 22. Lower fan speeds and restriction from insulation caused added condensation inside of unit, which dropped down to pan, and stopped unit from unit by filling up auxiliary pan and engaged safety switch.

During installation the drain line got knocked out of place causing the water to drain onto the basement floor instead of down the floor drain, I took photos of before and after. I added a tail piece to hold the drain in place and strapped it in place as well. I poured gallons of water through it to check for proper drainage without leaks. I used shop vacuum to get up most of the standing water. The remaining water does not easily get vacuumed up and will therefore start the drying process fairly quickly. I called the install manager and sent them photos as well. Customer does not use the basement had no reason to move the drain out of position. It must have gotten out of the floor drain hole when the installers were tying it into to the new unit.

Upon arrival all systems cooling properly and components operating normal. Upon inspection of furnace found blower wheel has substantial layer of dust build up. Recommend cleaning. Upon inspection of upstairs blowers found both have a large amount of bacterial growth on fan wheels and is spreading through inside of unit. Coils still appear clean. Recommend at a minimum having fans cleaned but strongly suggest having both units taken apart and cleaned thoroughly. Attached estimates for options.

Upon arrival I was told that thermostat was blank. During diagnostics I found puddle around condensate pump and pump tank full, float switch engaged shutting power to thermostat. Customer explained he shut off power to pump because it constantly ran after he cleaned it. Returned power to pump and found it didn’t turn on when full. Manually pressed down float and pump started running. When empty the pump continued to run automatically. Float switch is not operating and pump is causing system to shut off. Quoted customer to replace condensate pump but he declined. Would like to do it himself.

System operating normal, recommend ez trap to prevent from water damage, also recommend customer use sturdier filters, current band being pulled into blower. Customer complaining outdoor creating more noise, system seems fine outside, all components good, contactor nearing end, only cause for excess noise could find is dirty coil, recommend customer have us thoroughly clean instead of customer with hose. Customer agrees and is interested in having us back out to install ez trap and clean coil, said he needs to talk to his wife first.
