Load analysis

Completed AC tune up for 3 Ton Trane heat pump system Aprilaire 413 filter ok; I informed the, to order more for future use. Indoor and outdoor coils in good condition Inspected wiring, controls, electric motors and components; equipment has surge protection Measured temperature split (71-51=20°) and static pressure Inspected drains; cleared EZ trap, tested pump; Checked integrity of compressor motor (mega ohm test) Assessed refrigerant charge checked pressures. 10° SC. Good Offered WiFi thermostat with $100 discount. He decided to keep the T6 non WiFi and set a programmed schedule. *Heat pump droop is set to 3° System operating well at this time.

Replaced both boards inside 4 yr old attic crawl space air handler. Daikin proprietary thermostat still flashing red with error. Unable to determine cause of error. Office to schedule lead tech to diagnose issue. No payment was collected today. Also found outdoor surge protector tripped. Removed from circuit but error still persisted on thermostat.

7/1/26. Fully assessed no cooling situation on 2016 carrier split a/c system. Found burnt up hard start kit, capacitor, and double pole contactor. Also found hole burnt thru electric panel cover on unit. Wayne wanted to replace burnt up parts to see if compressor was ok. Checked compressor with megometer it passed. Replaced all parts an cut off burnt up wires. Everything was supplied by riverworks except double pole contactor. Tested a/c operation. Compressor amps were 10 amps which were good. Checked r410a refrigerant pressures they were 359/125 16 subcooling and 12 superheat. 13 subcooling is what it calls for so not bad. A/c is working properly at time of service.

6/29/26. Performed quality assurance on recently installed magic pak a/c and gas furnace. Checked over all electrical connections and components. Checked refrigerant pressures and temperatures. Checked temperature split it was 19 degrees. Checked manifold gas pressure in heating mode which was 3.51 w.c. System is working properly at quality assurance check.

6/29/26. Went over trouble shooting the reversing valve with Andrew from Ferguson tech support. Gave system a call for cooling and had no voltage to the reversing valve and system was still heating. Switched over to heating mode and had 209 v ac. Tapped on the valve and it will not shift. Andrew is going to speak with his higher ups to see if next steps,

6/29/26. Performed quality assurance on recently installed trane gas furnace a/c, checked all electrical connections and components. Found wet switch wired into the system wrong. Found wet switch r tied into safety loop not circuit board, re wired and tested wet switch operation. Checked temperature split. Checked 454b refrigerant pressures and temperatures. System is working properly at quality assurance check.
