• Upon arrival, the client reported that the outdoor unit and air conditioning system were not working. • Went to the thermostat and set it to cool. The blower motor activated inside the home. • Inspected the condenser unit and found multiple component failures: • Blown high-voltage fuses • Failed hard start kit • Failed run capacitor • Discussed findings and repair options with the homeowner. • Client approved repairs. after repairs • Cycled the system on and verified proper start-up and operation. • Checked starting and running amperage — all within manufacturer specifications. ⸻ System Condition Upon Completion: • Hard Start Kit: Replaced • Run Capacitor: Replaced • High-Voltage Fuses: Replaced • Amperage Readings: Normal • Cooling Performance: Verified and operational • Overall Status: System is cooling properly at this time ⸻ Recommendations: • Due to the age and condition of the system, strongly recommend system replacement to ensure long-term reliability an

Service Type: Demand Service Technician Summary: Upon arrival, the client reported that the system was not operational. The 1050 thermostat was displaying a hard lockout. I reviewed the system’s alert history via the diagnostic flow chart. The records indicated two key issues: • Communication failure with the outdoor unit • A possible high-voltage issue I proceeded to inspect the electrical components: • Verified incoming power at the disconnect box • Checked power output to the condenser • Tightened all contact points I de-energized and then re-energized the equipment. During reassembly, I noticed a buzzing noise coming from the disconnect box, indicating an electrical arc. Upon further inspection: • Tightened the disconnect prongs • Tightened the fuse brackets • Replaced both fuses After re-energizing the system, the buzzing noise was no longer present. I moved and tested components within the fuse box to ensure all connections were secure—everything was tight and prope

Estimate options. Client would like to repair in 2 weeks.

Service Type: Demand Service Unit Serial Number: *****6P31F (Back Bedrooms Unit) Technician Summary: Upon arrival, the client reported that the bedroom unit was not functioning. I inspected the thermostat, which was set to 78°F, while the indoor temperature was reading 83°F—indicating the thermostat was calling for cooling but the system was not responding. I proceeded to inspect the equipment. First, I verified that power was present at both the condenser and furnace. I also confirmed the presence of 24V at the circuit board and the communicating relay panel. (Note: Thermostat is a wireless model.) I then bypassed the thermostat to rule it out as the issue; however, the system still did not initiate any functions. All wiring and connections were verified to be intact. Based on these findings, I determined that the circuit board has failed. Next Steps: • Will contact American Standard on Monday to obtain replacement parts. • Will follow up with the client to provide an ETA for

Service Type: Demand Service Technician Summary: Upon arrival, the client reported that the living room thermostat was displaying a temperature reading noticeably lower than the actual room temperature. The client had placed three independent temperature sensors adjacent to the thermostat, all showing a discrepancy of approximately 5°F above the thermostat reading. To verify the issue, I used my own calibrated temperature sensors and placed them directly on top of the thermostat. The results confirmed the client’s observation, showing a consistent 5°F difference. A supervisor arrived on site to assist with diagnostics. Together, we conducted multiple tests on both HVAC units. We verified the full cooling sequence of operations for each unit and confirmed that both systems are operating according to the manufacturer’s specifications. To resolve the issue, we replaced the Ecobee thermostat. Before departing, I rechecked the temperature readings. The new thermostat’s reading aligned c

Demand Service Report Unit Serial Number: W2M1650737 (Bedroom Unit) Issue Reported: Upon arrival, the client directed me to the condenser unit, where the refrigerant lines were visibly frozen. He also mentioned that one of the guest bedrooms was not cooling properly. Diagnostics and Findings: • Inspected both thermostats and found a 5°F discrepancy between the set temperature and actual room temperature. • Inspected the iced-up system and found the evaporator coil frozen. • Replaced both 16x25 air filter, located within the furnace/ garage upflows • Checked refrigerant charge on the affected system and found it was slightly low on refrigerant. • The system uses R-407C, a substitute for phased-out R-22. Repairs and Recommendations: • Informed the client that R-22 is no longer available and its substitutes, refrigerants including R-407C, are phased and no longer unavailable. • Added 2 lbs of R-407C to bring refrigerant pressures back within normal operating range. • Verified

Demand Service Report Unit 2013/ 5 ton Horizontal split system Issue Reported: Upon arrival, the client stated that the condenser fan motor was not spinning at full speed. Diagnostics and Findings: • Set the thermostat to cooling mode; indoor temperature was over 90°F. • Upon further inspection, found that the system capacitor was swollen—likely due to excessive heat. • Recommended the following to the client: • System membership for ongoing maintenance benefits • Installation of a hard start kit • Replacement of the faulty capacitor • Client approved all recommendations. Repairs Completed: • Replaced the swollen capacitor • Installed a hard start kit • Performed a courtesy rinse of the condenser coil • Verified refrigerant levels and temperature split Results: System is now operating and cooling properly, with all performance parameters within manufacturer specifications.

Bedroom system Service Report – Demand Call Client Concern: Upon arrival, the client explained that the home has two zoned bedrooms. The thermostat in guest bedroom is functioning correctly and cycles on and off as expected. However, the master bedroom continues to receive airflow even after the thermostat has reached the desired temperature. Diagnosis: • Inspected zoning system at the attic zone panel. • Performed testing on all zones. • Found that the 16-inch damper for the master bedroom zone is stuck in the open position. • This is causing the continuous airflow in the master bedroom regardless of thermostat settings. Recommendation: • The 16-inch damper for the master bedroom zone will need to be replaced to restore proper zoning functionality. Next Steps: • Will follow up with the client later today with an ETA once contact is made with the supply house regarding damper availability. • Repair pending parts availability. Additional Notes: • Spoke with the client reg

Air conditioning not cooling. New problem found equipment low on refrigerant. Per tenant equipment was cooling great this last month since last repair which was capacitors. Performed diagnostic and found leak inside outside unit. Will submit work order for leak repair to property manager and wait for approval. In order to repair leak will have to remove all 8 pounds of refrigerant from system and repair leak. Then once repaired will have to weigh in new 8 pounds of refrigerant. Did add a couple pounds for temporary cooling though advise will leak out again until repair is complete. Emailed repair estimate also attached below.
