Upon arrival I removed all refrigerant from system, 140oz. Removed filter drier and txv. Installed new txv and filter drier. Pressurized with nitrogen to 400psi, no leaks. Removed nitrogen and vacuumed system down to 500micron. Replaced control board while unit was vacuuming. Added factory charge of 140oz. Returned power to system and tested ac using zone panel. Called for ac about 10 times and system cycled on normally every time. Called for ac from thermostat and checked operation. Unit operating normal. Customer said he has been hearing whooshing sound for attic system. Capacitors in spec and refrigerant charge normal. Customer doesn’t have oil trap, need to confirm with office about needed an oil trap or not to stop excessive noise. Finally customer said he is interested in installing buffer tank and Dhw pipes for supplemental water heating. He would like a call from office about this.

Upon arrival customer called for ac on both zones but system didn’t cycle on right away, Y1 and Y2 present at Board, no faults or error codes, but no voltage at CC or CCHI. Reset system and let unit naturally come on, when system came on it sounded like a lot of air pressure in ducts. Found zone 2 damper wasn’t opening when called, getting stuck. Had to remove actuator from damper, clean shaft and reattach set screw. Tested damper multiple times. Then put gauges on system because I found low delta air temp at evap coil. Compared refrigerant pressures to installation manual with 70 degree water temp, low suction pressure, high discharge pressure, high Superheat, high subcool, low delta air temp at Evap coil. Restricted txv, previous quote has been uploaded already. System satisfied thermostat during visit but discharge pressure was slowly rising. Let unit cycle on again but compressor didn’t come on until after 10 minutes of waiting. The call for compressor is being lost in the co

Upon arrival both systems cooling properly, temps and pressures in acceptable ranges. Run capacitor for downstairs unit below allowable variance, recommend replacing. Customer agreed to replace, tech does not have part on truck, office must contact customer to reschedule follow up visit. Customer prefers any day but Monday, anytime after noon. Customer will pay balance for replacement upon completion of work.

Estimate for Honeywell zone panel, 2-Water Furnace Intelli Starts. I started by installing the 2 Intellistart modules. The large one went in the package unit and the smaller one went into the cube. I tested by units operation to ensure start up of the compressors. Next I wrote down the configuration of the zone panel before removing power and the wires. I then installed new zone board and set to previous configuration. I tested the operation through the zone board. Customer came down and confirmed proper operation and damper positions.

While hanging crown molding yesterday customer inadvertently put a trim nail through the Tstat wire bundle. The wire was inaccessible to get to it and splice. The best option was to run the wire to a wall in the kitchen. Customer and I ran 15 ft of wire and I wired the Tstat and unit back together. I tested the unit with the aid tool and the unit is operating normal.

Another technician come out to find the problem collected $127 for capacitor replacement. No balance left for this job. I replaced the run capacitor. I tested zone dampers from the zone board and they open and close normal. Customer will video tape any future occurrence. Customer asked for an estimate to install Intellistart Module. I prepared a quote and verbally gave them the cost and will email it as well.

I replaced the air filter with one provided by the customer. I found the pressure drop and heat of extraction to be lower than printed data for this unit. The axb setup was at 50 and 100 vs pump which allows for maximum flow through the pump. There was no valve on the loop piping so I went to the pumps and the vs pump was warm and working but the other pump was cold and clearly not working. I found no voltage at the pump and traced it to inside the unit. I wired it into the fixed pump relay p1 and p2 and started the unit. Pump drawing .98 amps and the pressure drop actually needed to be slowed down slightly with both pumps working. I set flow rate correctly. Loop pressure was good. I checked the electrical wiring and electrical systems, all are within specification. Unit operating normal.

Called customer and he informed me that nobody would be home during service. During diagnostics I found no LED lights at boiler or zone panel. Checked voltage and found none at boiler. Got access to basement of house per customer and I found 20amp breaker tripped. Reset and tested unit operation. Also labeled breaker. Found 10amps total ONLY when boiler is firing up. During normal operation I found unit was pulling 6.5amps total. Checked operation of pumps, boiler, stat, and zone control. Amp draw readings taken were from main power at breaker reading all motor amperages. Found P/T sight glass on boiler is full with water and difficult to read. Continued to run system and found no additional problems. Suggest 20amp breaker get replaced, possibly weak and prematurely tripping. Left system running to make sure Desert Aire System satisfies and customer sees that it is working. Locked basement door and front pool door. Left back pool door unlocked. Office please follow up with customer. N
