Once we arrived we checked filter also dampers and motors, ducts checked sub cooling and added 1lb. Of 410A freon unit is operating normally at this time.
On arrival found no fault,found system operating normal
Spring Pm On 07/12/19 On arrival set unit to call for cooling measured supply and return air temp measured voltage and amps inspected electrical connections checked drain and cleaned checked filter cleaned checked blower capacitor checked condenser coil outdoor checked compressor capacitor checked electrical connections checked voltage and amps checked pressure and temp and they are ideal indicating zero leaks tested unit operating normal at this time. Highly recommended duct needs to be cleaned ASAP.
Upon arrival I was told that rear office ac wasnâ€™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.
Warranty call on arrival turn off the unit removed the surge protection call SCM60 from high voltage disconnect box put the wires back tightened up the wires tested checked electrical connections checked voltage and amps measured supply and return air temp unit operating normal at this time. No payment collected.for more info I take pictures for SUPCO IMPORTANT NOTES and attach to the history.
Spring Pm On 06/20/19 On arrival set unit to call for cooling measured supply and return air temp measured voltage and amps inspected electrical connections checked drain and cleaned checked unit filter cleaned checked EWP and LWP also temp checked compressor capacitor checked all other electrical connections unit operating normal at this time. Also customer has issues with thermostat he explained to me I put my AURORA total no fault tested the thermostat I believe customer set the thermostat 1 degrees different that way the thermostat keep on and off Avery 1or 2 minutes unit operating normal at this times.
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.
Spring Pm On 06/19/19 On arrival set the unit to call for cooling measured supply and return air temp measured voltage and amps inspected electrical connections checked drain and cleaned checked filter cleaned checked compressor capacitor the voltage absorption system was well below spec so I suggested replacing now avoid future problems I gave quote for customer accepted replacing the compressor capacitor tested checked electrical connections checked voltage and amps checked EWP and LWP also temp checked all other electrical connections start up and unit began operating very smoothly without any hesitating unit operating normal at this time. Collected $83 on C.C on file.
Replace 40 gas atmospheric vent not power vent water heater. Leaking is coming from the bottom of water heater. Advised it will need replacing.
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 didnâ€™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.
Found secondary drain pan filled with water. Blew out condensate drain line and checked the trap. Found system low on refrigerate charge. Checked for leaks. Added 1 1/2 lbs of 410A refrigerate. Checked operation. P.o. # for DCM190525
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.
found that the condenser would come on but not the AHU blower. linked the AHU with the condenser. Checked operation.
On arrival found system has a leak,customer bought new coil and outdoor unit to be installed on Thursday
No need to do a leak search because the suction line at the condenser was crimped and cracked. The customer had moved the condenser over a few feet during the winter time. The unit is on a pad and customer was happy with its position. I brazed in some pipe to fix the leak. I replaced the filter drier indoors. I replaced the valve stems and installed brass valve caps. Pressurized with nitrogen to 250psi and let it hold to prove that there were no other leaks or leaks on what I had repaired. Flushed lineset with the nitrogen and pulled into a 500 micron vacuum. Charged system with 8lb oz of r410a until I had 9 degrees subcooling and more than 20+ degree delta temperatures across the evaporator coil. Unit operating normal. Advised the customer that the unit will need to operate for some time to reduce the heat in the home. It was 83 degrees when I left. Customer signed up for service membership today so I waived the trip fee and the repair was discounted by 15%.
On arrival set thermostat to call for cooling. Measured return temperature, supply temperature, amps, voltage, EWT,LWT,EWP, and LWP. inspected electrical connections, contactor is ok, filter is clean, evaporator coil is clean, and blower wheel is clean. I cleaned condensate drain pan as well as the condensate drain line. Measured voltage absorption system rated for 30mfd. Actual reading 29.81mfd. System shows no faults at this moment. Recommended a wet switch and a uv-light. System is operating normal at this time.
On arrival I removed defective uv light .i then installed new uv light .tested it .unit operating normal
Spring Pm On 04/25/19 On arrival set unit to call for cooling measured supply and return air temp measured voltage and amps inspected electrical connections checked drain and cleaned checked filter and replaced checked EWP and LWP also TEMP is good checked compressor capacitor unit tested unit operating normal at this time. Recommended UV lights installation.
Invoice created to clear up AR
Both the evaporator and condenser coils are clean, as well as the blower wheel and media filter. Blower is set on high speed for cooling and itâ€™s op properly so airflow is not the issue with the unit on cooling by 14.5 degrees across the evaporator coil. I placed gauges on the system along with pipe clamp thermometers and let the system run at least 10 minutes before taking my readings. Suction pressure low, discharge pressure low to normal but 32 degrees superheat. There is a refrigerant leak either in the system and most likely in the evaporator coil. The unit uses r22 so the EPA does not allow for topping off. I gave the customer 2 estimates, both include a leak search. One estimate to fix the leak if itâ€™s mechanically fixable and one to replace the evaporator coil. Both would include charging with conversion refrigerant. Customer is not sure what they want to do and also wanted a free sales estimate. A sales person is scheduled to come next Saturday, 04/27.

Upon arrival I was told that compressor was making loud squeaking noises. Customer also asked how to replace humidifier pad. Went to furnace and showed customer how to replace humidifier pad and clean drain because he would like to do this himself moving forwards. Put gauges on ac unit and called for ac from thermostat. Ran ac and didnâ€™t hear noise customer was referring to but I found low suction pressure and no Superheat, suction line frosting. Went to furnace and found furnace only moving 900cfm and running in continuous fan, not high cooling. Found thermostat wires for ac connected to Y2 and not Y1. Installed jumper wire from Y1 to Y2 because this is a single stage ac unit. Called for ac again and furnace now moving 1800cfm. Went to outdoor unit and we now have normal Superheat and subcool, refrigerant looks normal. Compressor and od fan amperage normal. Closed discharge line to test compressor pump down and found compressor pumping down normally. Shut off ac unit and checked ohm
