Timely, courteous, knowledgeable; for Chris Alexander!!!! Very personable.
On arrival found system locked on low pressure.found system running on low pressure .found evap coil leaking .need to replace evap coil also found cap under manufacturer specs also filter is dirty and also recommended duct cleaning after construction is done . Could not get hold of customer!!!
Unit #2 was very low on refrigerant charge and the coil was freezing up causing excess water to get blown out of the pan by the blower. Unit was only cooling with 6-8 degrees. I isolated txv bulb to make sure it was operating properly and then performed electronic leak search. Leak detector picked up a leak just in the attic air alone and narrowed it to a place on the bottom row of tubing towards the blower side, in the middle of the coil. It cannot be repaired and the coil has to be replaced. Customer approved the repair. I completed a parts order form. I did charge the system so that it is operating in the meantime. Customer signed up for service membership for two geo units. I was unable to perform the maintenance today and the customer would like it if they could be done when the coil is replaced?
On arrival set thermostat to call for cooling. Measured return temperature, supply temperature, amps, and voltage. Measured EWP,LWP,EWT, and LWT. Inspected electrical connections, contactor, replaced filter provided by customer, blower wheel is clean, evaporator coil is clean, pressurized system to 65psi, cleaned condensate drain line as well as condensate drain pan. Unit is operating normal at this time.
On arrival flipped the uv light upside down.unit running normal
installed (1) Apco UV light.tested it ,unit operating normal
On arrival checked thermostats were calling for cooling. Measure return and supply temperature, EWT,LWT,EWP,LWP, measured amps, voltage, inspected electrical connections, contactor, capacitor, blower motor wheel is clean, evaporator coil is clean,replaced both filters provided by customer. units are operating normal at this time.
I replaced the units filters with ones provided by the customer. I cleaned the condensate pans and drain lines. I pressurized the ground loops to 65 psi. I confirmed proper flow rate and heat of rejection for each unit. I checked the electrical wiring and electrical systems, all are within specification. Recommended Intellistart module be added to each unit to help protect the compressors. Customer will consider. I had 20+ degree delta temperatures across the evaporator coils. Both unit are operating normal. I also recommended adding EZ Trap to the attic unit. The unit has a pan switch but if the drain backs up the EZ Trap will turn the unit before the pan and unit get flooded and possibly the ceiling below them.
Spring Pm on 03/28/19 On arrival set units to call for cooling measured supply and return air temp measured voltage and amps inspected electrical connections checked drain and cleaned checked filters and replaced checked EWP and LWP units tested units operating normal at this time. Recommended install Uv lights for both Units.
Upon arrival I found Check Valve Backflow Preventer on Water Feeder had failed. Replaced with new and verified no water feeding back into water heater. Bled all contaminated water out of water heaters. Took water sample of loop so we can make sure that wasnâ€™t contaminated as well. Water Meter now reading 296.115 gallons after repair.
Warranty per Alex. Upon arrival customer showed me to units and flow center. Started by tracing all loop piping and checked for leaks, none found. Can see evidence of previous leaks but nothing indoors is currently leaking. Static loop pressure at about 23psi. Connected water meter from bottom of buffer tank to flow center (out). Water Meter before purging at 293.69 gallons. After purging and equalizing pressure at 293.85 gallons. Static water pressure at about 56psi. Showed customer water meter setup and explained how it works and how to read the meter. They may document how much water has been added, I left the box with the original value if they would like to do so.
I operated the unit on cooling mode #9 and set the flow rate to 9gpm by setting the pressure drop to 2.5psi. I cleaned the condensate pan and drain line and ran hot water to flush it out and to make sure it drained properly without leaks and that the condensate pump was working. I checked the electrical wiring and electrical systems, all are within specification. Filter is in good shape. I pressurized the ground loop to 65psi. I reset blower speeds from 5,5,10,11 to 3,3,10,11. I turned dehumidication on from the thermostat and explained all of this to the customer. Unit operating normal. I recommended adding a Blue Tube UV lamp but customer was not interested. I also recommended installing a whole house surge protector to the main panel box to protect the equipment. Customer asked for an estimate and would like to have this done next maintenance.
Replaced kitchen faucet with single handle faucet with pull out sprayer , adjusted price to also replace cold side angle stop customer unable to pay full amount after approval of valve as well stopped and gave estimate to replace both valves under kitchen sink also showed customer how to turn up heat on water heater customer responsible if turned up past scalding balance is being *paid by cash* $505.00 - $100 off Angie list coupon
On arrival found fp1 at 30 degrees ,changed it to 15 degrees .unit back on normal
On arrival found defective condensate pump .changed it ,unit operating normal
On arrival found system operating normal,found system had locked out on fp1 ,found fp1 was set to 30 ,reduced it to 15 .customer bought a membership.unit operating normal
Customer complaint that on both thermostats the back light would not come on and would not turn off the unit. I checked inputs from each thermostat at the zone board and they are normal. The back lights were lighting up now. Itâ€™s difficult because the unit was operating normal from the zone stats and the zone board. Without being able to see the problem I cannot condemn the thermostat or zone board. I checked temperature rise on the unit and heat of extraction and itâ€™s within specification. Maybe it was an anomaly. I put an estimate in the system for replacing one or both thermostats.
Replace freeze protection sensor and checked operations.
Upon arrival I spoke with Bryan from Magnolia/Best Buy as he was the salesman for this automation system. He gave me thermostats and informed me that customer was unavailable because he was working and had conference calls. Contact then showed me to all thermostats. Started by replacing all Honeywell 8000 thermostats with smart Savant thermostats. Shut down power to all units. Removed old thermostats. Cleaned wire connections. Installed new thermostats. Returned power to systems. Thermstats now reading â€œPlease Configure this Deviceâ€. Cannot confirm operation because Magnolia/Best Buy is not finished and they are programming thermostats. We did not supply these thermostats so we are not liable for warranty purposes. Also could not collect from customer because he was unavailable.
Found faulty sensor . Called tech support and spoke with Bill . Sensor was not reading anything and giving a FP2 fault and causing the unit to lock out . Need to replace sensor
I replaced all filters that were provided by the customer. I confirmed/ adjusted the flow rates and pressurized the ground loop to 65 psi. I checked the electrical wiring and electrical systems, all are within specification. I slowed blower speed for the attic air handler to increase temperature rise. I made sure auxiliary heat strips were operable. Both units are operating normal. In regards to the humidifier service, I replaced the water solenoid valve so that it would distribute water during a call for humidity. The original solenoid was inoperable, despite receiving voltage. Humidifier is working properly without leaks.
I tested auxiliary heat. I installed two jumper wires on the auxiliary heat board so that the timing of the elements is correct. The unit had recorder 999 out of envelope faults. The blower speeds were incorrect. I changed them from 4,6,10,11 to 2,3,10,11. I then operated the unit on compressor speed #12 heat mode. Refrigerant pressures were normal. I slowed flow rate by 15%. Heat of extraction matches printed data. I checked the electrical wiring and electrical systems. I enabled dehumidication on the thermostat. I pressurized the ground loop to 65psi. Unit operating normal. Customer may want to consider adding a humidifier to the system. I will send an estimate.
