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.

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.

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.

on arrived recovered refrigerant.then removed defective expansion valve ,then replaced new one ,checked for leaks ,vacuumed systen .rechared it 60oz of 410. Tested unit on heat and cool mode .unit operating.normal
On arrival found unit not operating due to a defective inducer motor and limit switch. Customer wants to replace indoor and outdoor unit.
Turned system on and checked operations . Took a video of the blower while running to show costumer. There was no noise and everything working . Can hear rattling from unit in conference area . Unit is right above and the disconnect and doors rattle when unit is running from vibrations. I put foam behind disconnect and I screwed cabinet doors tight to limit sound . Unit is directly above so costumer will hear some noise from unit .
I replaced the compressor and installed a new filter drier. I flushed system with dry nitrogen. I used 250 psi of nitrogen as a leak test and it held for ten minutes. I pulled into a deep vacuum and added 15.77 lbs factory charge plus an additional 3lb 2 oz to account for the very long lineset. Operating pressures matched data plate and the unit went into second stage operation and defrost cycle normally. Unit operating normal. Customer paid the balance $1,183.50 with a check today. The previous deposit will zero out the invoice.
Upon arrival I was told back right area unit not heating. Went to thermostat and found it calling for aux heat but unit not running at all. Found 3amp fuse blown. Replaced and tested system. Found unit not tripping fuse but reading voltage on thermostat wire that should not have any voltage. Went to condenser and found thermostat wires (G and E) touching each other, bleeding voltage and potentially blew fuse. Used wire nuts to cap each wire thatâ€™s being fed voltage. Wires now not reading voltage unless called for. Tested defrost mode, heat, and aux heat. Unit operating normal and satisfied thermostat at 72.
Replaced blower motor assembly with shaft and barrings . Also replaced belt and started and tested system . System is operating properly , supply air 117 and return air 72 . Blower motor pulling 3.1 amps rated for 5.4 .
On arrival explained the customer to turn on the unit can be more damage customer agreed turn on the unit checked electrical connections checked supply and return air temp. Unit running at this time.
Found unit making a grinding noise / banging when I got up on roof . Took off my blower access door and found that the Blower housing is shaking . The wheel is ginding when it turns . Recommend replacing blower assembly with the shaft due to rust . Also would need to replace the belt which is an A52. Left unit off to prevent any damage being done to the motor .
