Upon arrival found water heater that is the buffer tank to be old and showing signs of rusting. Recommended replacing before it could cause damage to the hybrid water heater. I also recognized the 1/2 line going up wall pitted and need replacing ASAP. The lines look like it has been leaking from somewhere and caused lines to pit.

On arrival found system operating normal .recommended installing soft start .i installed new one .also advised customer if the problem happens again to call electrician .unit operating normal
Upon arrival we were told that all units werenâ€™t keeping up. During diagnostics we found sandwich prep area and main RTU area thermostats were set on a schedule which increased the indoor temp to 85 degrees at night and they want it to be down to 74 during the day, too large of a temperature drop for how much heat is being produced in building. Turned off schedule for sandwich prep area so it maintains 74 degrees. Changed middle RTU thermostat schedule to increase to 78 instead of 85. Then we found back area by office unit wasnâ€™t running, polarity switched again at AHU? I changed these wires a month ago and now I had to change them back in order to get 208 volts. Once I did so the unit came on and started working. Measured Superheat and subcool at condenser and found unit slightly undercharged, added .5lbs to bring subcool to 10, Superheat 14. Back right prep area unit was about the same, slightly uncharged and we added about .5lbs to bring subcooling to 10 and Superheat to 13. Fin
Service call on 07/08/19 On arrival set units to call for cooling checked indoor unit electrical connections checked voltage and amps no DT I go outdoor condenser unit I checked the unit is gave me error code for both units 92&93 #92 inverter VDC-out under voltage reset the unit checked high voltage electrical connections tested the unit is gave me another error code #93 230VAC under voltage i tray to call carrier tech support is closed so we have to come back tomorrow before 4:30pm to diagnostic the problem of the unit. Customer refused to pay dispatch fee and diagnostic fee unit we tell him the problem.
Upon arrival system operating normal. No noises, proceeded to check all modes of operation for blower motor, still no noise. Amp draw normal on motor and nothing seems out of spec and nothing to interfere with fan to cause noise. Gave quote Incase noise comes back up and customer interested in replacing motor. Customer complained that air filter access has been blocked by recently installed water heater. Gave quote for creating new access for filter on back side of return duct, would have to cut new hole and make new reducer for filter to fit into. Also gave option to upgrade to aprillaire if making new access. Would recommend contacting other company that installed water heater to relocate water heater allowing full access to filter.
Arrival found system was turned off .set unit to Ac .unit came on .found blower showing sign of failure .also system pressures slightly low at 32 degrees .unit is not operating normal.customer informed me that she is not ready to make any decision.unit could freeze again .
Service call on 06/25/19 On arrival set unit to call for cooling measured supply and return air temp measured voltage and amps inspected electrical connections checked air filter is bad condition I take out the filter and run the unit checked condenser unit I found the line set is building ice I cannot put my gauge to check pressure and temp we have to come back after the ice melt down customer schedule for tomorrow 8 to 12 collected $89 for dispatch fee on C.C. I turn off the unit is not running this time.
Upon arrival I went to furnace and checked operation of blower then ac. Somewhat high delta at Evap coil but customer explained of ducts sweating. Opened up furnace panel to find ac thermostat wire connected to Y1 instead of Y/Y2 when you have a single stage ac unit. Airflow increased immediately as soon as I changed wire at furnace control to Y/Y2. Also found airflow dipswitches were set for 350cfm per ton and not 400cfm per ton. On duct it is noted for customer to close main floor damper and open top floor damper. Main Floor is handle is broken and damper is open until replaced. Quoting customer to replace 10x7 damper. Finally when inspecting system I found condenser coil is dirty, quoting customer to clean. After speaking with customer she is going to see how adjustments helped when outdoor temps get hotter because today is nice and mild.
Upon arrival I spoke with manager and he informed me that he didnâ€™t notice any problems. He also said Stanley just left because he couldnâ€™t wait any longer. Went to each thermostat and found them all to be satisfied besides RTU. Went to roof and found circuit 1 frozen. I just added R22 to this system 2 days ago. Per Alex, we added nitrogen to bring pressure up to 300psi. Leak checked with bubble soap and leak detector. We found leak at Evap coil. We are quoting customer to replace coil but they may want to consider replacing, older unit. We went back into space because customer originally complained about High temps in kitchen prep area. We found system struggling to keep up because they only have 2 supplies in entire back kitchen area, per Alex we moved a few to front of store to help supplement RTU. We are going to quote customer to add 2 supply registers to back kitchen area. All other units are operating normally.
Upon arrival I shown to all thermostats not keeping up. Went to roof and found front dining Packaged System Circuit 1 was low in R22. Had some left in tank so I added what I could to bring Superheat and subcool closer to spec. Delta air temp was 14, now 24. Unit operating normal but quoting customer for leak search and repair. Then I went to sandwich prep area and found unit running normally but with high subcool. Removed about .5lb of 410a to bring superheat and subcool to spec. Delta air temp was 17, now 21. Then went to back right prep area. Found system slightly low in 410a, compressor was just replaced. Added 12oz of 410a to bring Superheat and subcool to spec. Delta air temp was 16, now 22. Then went to back right dining room unit. Found system slightly overcharged. Removed 9oz of 410a to bring Superheat and subcool to spec. Delta air temp was 17, now 22.

RTU #5: Carrier package heat pump roof top unit. Two wires coming off the compressor contactor were burnt in two and the contactor itself was badly burnt. Most likely old wiring overheated and pulled high amps and caused the wires and contactor to burn so that neither compressor would operate. I fixed the wires and replaced the contactor and tested the unit with gauges hooked up on each refrigerant circuit. Both circuits have normal operating pressures and characteristics. I closed the unit back up and left it running from the thermostat. Unit operating normal. Materials: 1) 2 pole contactor: 30fla: 24v Coil
System operating normal, condensate line comes to low point then rises back to level for length, suggest replacement, at least install ez trap to protect system from water damage. Contactor on outdoor unit is burnt, suggest replacement.
Replace to di-electric union boiler valves on water heater they are leaking. Replace with cpvc ball valves
COMPLETED THE PM.
On arrival system water pressure low, raised to normal operation pressure. System operation now normal. Found leak above water heater. Suggested customer schedule plumber visit. Customer wanted to talk to husband first.
FOUND UNIT 3 ( THE DINING ROOM UNIT ) IS LOW ON R22 REFRIGERATED CHARGE. THE LEAK MUST BE REPAIRED BUT DUE TO THE AGE OF THE UNIT AND THE TYPE OF REFRIGERATE, IT SHOULD BE REPLACED INSTEAD. FOUND ON THE 6 THAT THE WIRE GOING TO THE OUTSIDE UNIT FOR A CALL FOR COOLING HAD BECOME BRITTEL. REPAIRED THE WIRE AND CHECKED OPERATION.
Customer to buy and replace 1) 14*14*1 filter and 1) 20*28*1 filter. Evaporator coil was cleaned in the past and remains clean. Blower set to highest speed for cooling mode. One of the returns was covered with old ductwork and was restringing airflow to the unit by at 1/3. Unit was cooling with 22-24 degree delta across the evaporator coil. The unit is meant to serve the kitchen area and entering temperatures were 88-92 degrees and supply air of 64-68 degrees. I looked in the ceiling to see if any ducts were open and pulling in air above the ceiling tiles but all trunks were in tact. I went on the roof and had normal operating pressures for r410a refrigerant with 8 degrees superheat for a fixed orifice metering device which is normal. I took a picture of the low side gauges with thermometer reading suction line temperature. I checked the electrical wiring and electrical systems indoors and outdoors and capacitors were at full value. I could not identify any problem with the equipment e
Reversing valve replacement
