Up on arrival performed fall maintenance. Checked all electrical components, checked system for operation. Found blower motor assembly need new bushings , electrical air filter that we installed needed a new top filter. System working good at this time. Dispatch to follow up with customer regarding warranty coverage on bushings and electronic air cleaner
I checked the gas pressure in low and high fire. I checked thermostat operation for low and high fire. I checked temperature rise in high fire and it is within manufacturing range. I checked the electrical wiring and electrical systems, all are within specification. Unit is operating normal.
Install customer supplied Nest thermostat. I installed the thermostat and set it up for the type of system. I replaced the air filter. I checked the electrical wiring and electrical systems, all are within specification including the auxiliary heat strips. I forced defrost cycle at the outdoor unit. Temperature rise is 25-30 degrees. Unit operating normal.
On arrival checked both thermostat turn circulate air on This particular home both units circulate air doing fall and winter time. heat source is in the basement area thatâ€™s not covered by supreme air. So then I checked amps, voltage, electrical connections, blower wheel is clean, evaporator coil is dirty. condenser coil is clean, electric filter is clean. Indicator light shows filter is Midway of being ready to be change at this time. I explain to customer check in about 30 days Unit operating normal at this time. I gave three estimates. To add whatâ€™s missing search protection for both air handlers and also coil cleaning for both air handlers also. I also explain the benefits of having a UV lamp On both air handlers to kill bacteria in the system.
Will have to spend about an hr in order to properly diagnose the problem within the ceiling.not responsible for ceiling. Will give over one of our partners for ceiling repair. Once I cut into ceiling found the drain to the shower pan leaking from the grate top portion. Installed a new grate silicones the edges. Told customer to refrain from using shower till tomorrow in order for caulk to set up. I tested it without chalk works great just needs a sealant for it to force the flow of water down drain.
Upon arrival was told by customer had newly installed unit and after now has no hot water. Upon further review found pilot off at water heater. Possibly shut down gas main to house to work on hvac and didnâ€™t know water heater was also a gas appliance. Water heater was in a separate location and in a closet in the garage. Pilot is on and unit is running.
On arrival found system operating normal,no whining noise .increased fan speed to 12 to check it .i didn't hear anything.unit is operating normal
Warranty call on arrival turn off the unit from disconnect box install new packard surge protector DTK -120/240CM+ tight up turn the unit on set the unit to call for cooling measured supply and return air temp measured voltage and amps inspected electrical connections checked all other electrical connections unit operating normal at this time. No payment collected is under warranty.
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 doesnâ€™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.
I transferred the badge plate and the coil bumper onto the new grille and then installed it.
Spring Pm On 08/08/19 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 check all electrical connections the indoor unit checked condenser unit outdoor checked electrical connections checked compressor capacitor checked voltage and amps measured pressure also temp and they are ideal indicating zero leaks checked coil checked all other electrical connections the outdoor unit tested unit operating normal at this time.
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 wasnâ€™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 wasnâ€™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.
On arrival checked delta t 18 degrees.checked filter ok.checked refrigerant pressure ok.found no faults on Aurora aid tool .unit operating normal
Upon arrival we spoke to customer and he explained that system faulted the other day and hasnâ€™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
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.
