Tech washed and serviced unit Customer extended psa

Unit is a 7 year old Payne package heat pump. Tech found low voltage fuse blown due to a wire rub where high pressure switch wire was shorted to cabinet. Tech was able to isolate short with electrical tape and replace fuse. Tech removed unnecessary batteries from thermostat and tested system in each mode. No further issues found. Tech recommended regular ESA preventative maintenance on system to keep unit operating efficiently and last as many years as possible. Customer declined saying funds are tight right now.

Tech found condenser for number 8 was not operating even with y call. Upon further inspection tech found system completely void of refrigerant tech called Jeff and informed him on finding and got approval for leak search tech added 1 lb of 410a and pressurized system tech found a leak in evaporator coil in a/h in hall way as well as in condenser tech could not pin point exactly where location of leak is on condenser due to wind not allowing tech to get exact confirmation but there is a leak present. Tech spoke with Jeff about leak and recommend replacing due to age and having leaks in both areas. System is heating with heat strips only.

-Performed cma inspection on 12 split systems. Performed inspection of oven hood and make up air. -Split System 2: Signs of heat damage and pitting on compressor contactor. Recommend replacement of contactor. Provided estimate $252.55. Compressor megged as caution. Windings shorting and compressor may be due for failure. Customer should consider replacement of system. -Split System 3: Outdoor fan capacitor tested weak. Provided estimate for replacement of capacitor $202.56. -Split System 5: Signs of heat damage and pitting on compressor contactor. Recommend replacement of contactor. Provided estimate $252.55. -Split System 7: Outdoor fan capacitor tested very weak. Provided estimate for replacement of capacitor $198.14. Outdoor fan motor amperage high. Compressor megged as caution. Windings shorting and compressor may be due for failure. Customer should consider replacement of system. -Split System 8: Blower motor capacitor tested weak. Provided estimate for replacement of capaci

System #5 Replaced a braze-in high pressure switch and Biflow filter dryer while flowing nitrogen, that was diagnosed by a previous tech, Pressure tested to 300psi. Pulled vacuum below 500 microns. Wired up the pressure switch back in its circuit as it was, factory Charged system with 11lbs of R410a. System is back up and cooling. Repairs were pre-approved.

Lobby and front office unit is #1 that was recently installed. Customer is not having issues with unit #2. The challenge with #1 was Honeywell vision pro following an undesired schedule. Tech changed install setup to “non- programmable.” New install Trane system #1 is cooling. They reported that the system not cooling is system #5 for kitchen and laundry. Tech found indoor unit blowing air, but outdoor unit not running. Tech found high pressure switch stuck open. Tech found outdoor fan blade sitting very low on fan motor shaft and fan blade spinning below the round discharge air fan oriface in top panel. Motor shaft looks like blade has slid down shaft. There is a groove where set screw rubbed motor shaft. Tech bypassed high pressure switch and recorded refrigerant pressures before and after adjusting fan blade. Tech securely tightened set screw to motor shaft after adjustment. System is back cooling after adjusting fan blade and bypassing high pressure cutout switch. Tech billed fo

Install EZ Trap on IDU-5 per prior approval.

Added condensate EZ Trap to IDU-10, 8, per prior approval. Replaced heat strip contactor on IDU-9 per prior approval. Replaced outdoor fan motor capacitor on ODU-1, 5, 10 per prior approval. Heat strips still in need of replacement on IDU-9 air handler. System may need further diagnosis now that contactor has been replaced. Identified problem with ODU-5 condenser not coming on when called by thermostat or manually jumper at unit. Demand tech to be dispatched for further diagnosis.

FOUND EVAPORATOR COIL COMPLETELY FROZEN UPON ARRIVAL. ALLOWED TO THAW/TESTED DAMPER MOTORS NO CHALLENGES. HAD MULTIPLE HITS WITH LEAK DETECTOR AT CORRODED/RUSTED AREAS OF EVAPORATOR COIL. BRYCE IS HEADED ON SITE.

Tech performed ESA on 1 system found no issues at today’s visit, system working properly at this time. Customer was concerned with ducts tech inspected ducts with no issues.

Performed cma full service on 12 split systems. Performed inspection of oven hood and make up air. Found fan capacitor on HP-1 tested weak. Provided estimate for replacement of capacitor $196.98. Found fan capacitor on HP-5 tested weak. Provided estimate for replacement of capacitor $200.50. Found compressor capacitor tested weak on HP-10. Provided estimate for replacement of capacitor $211.77. AH-1 evaporator coil leak present. Found duct work poorly insulated and sealed. System over 10 years old, recommend estimate for replacement of system. Found excessive buildup on evaporator coil on AH-4B (kitchen). Cleaned multiple times. Found extreme buildup on evaporator coil on AH-4A. Recommend more frequent replacement of air filter. Recommend installing air filters on return grilles. Found thermostat 10 off upon arrival. Found blown 5A low voltage fuse in air handler. Replaced fuse. Unit currently operating correctly. Found heat strip contactor on AH-9 severely corroded and not pr

REPLACED FAILED DUAL RUN CAPACITOR. SYSTEM BACK UP AND RUNNING. INVESTED IN PSA 1 SYSTEM.
