On arrival installed the whole house surge protector.green light was on .
Spring Pm On 08/06/19 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 blower motor cleaned checked coil cleaned checked all electrical connections in unit checked EWP and LWP also temp unit tested unit operating normal at this time.
On removed bad board .then installed new board .unit came on .checked delta t 20 degrees .unit operating normal
Found the unit had stop working after power outage. Reset the circuit breakers and got line and control voltage back up. No display on the circuit board but the fuse is good. Called tech support to verify that the board is bad.
Upon arrival I was told front unit wasnâ€™t cooling. Went to roof and found system not running, started to remove panels when unit cycled on then off again. Connected gauges to system and found unit was tripping high pressure switch. Switch is rated for 400psi open and 300psi close, this seems a little too low for 410a System. When unit starts it pushes 400psi then drops back down to 350psi. Need to replace switch with higher rated one.
Replace low pressure switch and belt on Goodman RTU. Installed the new belt. Was unable to install the new high pressure switch due to the new refrigerate fittings. Will need to return to install new switch tube. Cut out bad pressure switch. Brazed in a new tube. Pressure test circuit with nitrogen and checked for leaks. Removed the nitrogen charge and put the circuit into a vacuum. Charged unit with 13lbs of 410A refrigerate per name plate. Started unit and checked operation.
The owner started the unit. Unit ran on first stage at 63 degrees. Let the unit run for awhile and second stage came on. Discharge air dropped down to 50 degrees.
Unit is a RTU that requires a ladder to be set up. Upon my arrival It began to downpour and thunder and lightning. I let the customer know I was here and would wait to see if it blew over but it didnâ€™t. I called the office to let them know. I was advised to close out the dispatch as they would reschedule.
Upon arrival I found upstairs unit not running. Went to AHU and blower off, thermostat calling for ac. Went to Cube in basement and found condensate lockout code 6. Recalled all previous faults and found board only flashing 6 time repeatedly, condensate fault. Went back to AHU and found condensate Line/pan empty. Restarted unit and checked operation of ac. Found no problems with unit. Shut off system after 20 minutes of run time and inspected drain cabinet. Found drain sensor in pan had shifted and a lot of condensation was dripping right on top of drain sensor. Sensor interrupts ground so any contact with water will shut off unit. Covered top of sensor so condensation doesnâ€™t drip on it and moved back into place. Drain was just cleaned last month and is still clear, tested with water. Unit operating normal at this time.
Unit #1 uses 20x23x1 filter
iPad not working, no service, canâ€™t see jobs to bill properly, Darlene will call customer for billing in the morning. Customer also wants quote for replacing fan in upstairs unit with one that is weaker. Upstairs system oversized.
Upon arrival I found nobody on site. Called office and they asked me to take a look and see what I can find. During diagnostics I ran both systems and checked operation. The only vibration I could hear was coming from Daikin rooftop blower cabinet (rear system). Opened up panel to find blower wheel is rocking a little. Tried to adjust tension of belt and it made no difference. Spare cogged belt was inside of system so I tested blower with cogged belt and vibration stopped. Left AX52 belt on blower assembly instead of A52 because of vibration it was causing. Can not confirm exact noise customer is hearing because nobody is on site but I donâ€™t hear anymore vibration from system on the roof. Unit operating normal.
INSTALLED NEW FILTER SYSTEM.
On arrival found 1st floor unit locked on air flow ,found bad indoor fan motor .found second floor unit locked on condensate ,also filter 20x20x1 was very dirty.cleaned second floor drain and advised customer to replace filter ,2nd floor unit is operating normal at this time. Note : please check warranty status for indoor blower motor . Mrs baker paid $1631 and other half after we check the warranty and completion of the job
Set both climate master units to call for cooling. Both units were not coming on. I tried my best to figured it out but Problem was not up to my level of experience. Customer stated that there was a different company working on both units about three days ago. I was not able to get both units to run. Our lead tech is coming on Sunday morning. Customer is having friends and family in the evening due to a loss of a family member.
Spring Pm on 05/10/19 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 Unit #2 has electronic air filters model #5000 but it was not working properly bc the frame is broke I explained the customer to upgrade the air filter Iâ€™m suggesting to replace the filter kit to avoid future problems I gave quote for customer accepted we have to come back to replace the air filter also I checked condenser unit checked electrical connections checked voltage and amps inspected electrical connections checked compressor capacitor checked pressure checked all other electrical connections unit checked unit operating normal at this time. Collected $460 deposit on CC for aprilaire Model #2210 replacement
Performed ac pm on all 4 systems. All filters are pretty clean, attic and garage systems dirtier than the rest but ok for a few more weeks. Cleaned out vs drive screen on 7 series unit. Flushed out drains with brush and hot water. Tested condensate pump. Checked cleanliness of coils and blowers, all clean. Checked capacitors and contactors, tightened electrical connections. Closed all humidifier bypass dampers, open in winter, close in summer. Ran ac on all stages and checked operation. Measured amp draw of compressors, blowers, and loop pumps. Measured delta air temps. Measured delta loop pressures and temps. All units operating normal at this time.
I cleaned the condensate pan and drain lines and ran hot water to flush the debris and make sure it drained properly without leaks. I checked the electrical wiring and electrical systems, all are within specification. The washable filter was very clean. I operated the unit on second stage cooling mode and while I had 20 degree delta temperature across the coil, it was slow to reach it so I put my gauges on the system. While putting my gauges on I noticed refrigerant oils around the true suction valve stem. I tried tightening but I was picking up refrigerant using leak detector. I called the customer and proceeded to replace all 3 valve stems, leak check those and the braze joints and confirmed no leaks. I added 2lv 8oz of r410a refrigerant which increased my suction pressure to well above freezing, when converted to temperature. I charged until I had 13 degrees subcooling, normal Superheat and still maintaining 20+ degree delta temperatures across the coil. Unit operating normal.
