Performed a diagnostic on the Raypak pool heat pump. Upon arrival, the unit was displaying an HP error code, indicating a high-pressure safety lockout on the refrigerant side. I connected my refrigerant gauges and started the system to monitor operating pressures. The unit ran for approximately one second before the refrigerant pressure rapidly increased to 725 PSI, causing the high-pressure safety switch to shut the system down. Based on the pressure readings and system behavior, the TXV (Thermostatic Expansion Valve) appears to be stuck in the closed position, restricting refrigerant flow. I provided the customer with a repair estimate for TXV replacement, including refrigerant recovery and recharging the system with approximately 5 pounds of refrigerant. The customer also requested a proposal for complete system replacement. I spoke with Kenneth, who is currently working on the replacement proposal. Kenneth will contact the customer to review the proposal and discuss the availab

Performed a diagnostic on the system due to repeated lockouts indicated by four flashes at the condenser control board. Upon arrival, the customer had already reset the breaker, and the system was operating normally at that time. I inspected the air filter, and at the customer’s request, I replaced it and marked the installation date. I allowed the system to operate for approximately 15 minutes and tested both low-speed and high-speed operation. The system operated normally in both stages. I also checked the compressor startup amperage (inrush) and running amperage on both low and high speed. All readings were within normal operating conditions. Additionally, I inspected all supply vents throughout the house and found two closed vents, which I opened. I checked the temperature split, and the readings were within normal range. I also inspected the main electrical breaker and verified that it was properly tightened and operating normally. After completing these checks, I contacted Ada

Performed a diagnostic on the system due to an issue with the thermostat not providing the option to select Heat or Cool mode. I reset the thermostat multiple times and attempted to troubleshoot and reconfigure the settings. However, the thermostat continued operating in Auto mode and was not properly recognizing the heating wire (W). I replaced the thermostat backplate with another one, but the issue remained the same. As an additional troubleshooting step, I offered to test the system using a Honeywell Smart S200 thermostat from my truck. After installing the Honeywell Smart S200, both heating and cooling modes became available and operated properly. I explained the findings to the customer and confirmed that the replacement thermostat resolved the issue. The customer approved the installation. I programmed the new thermostat, configured the system settings, connected it to the Honeywell Home app, and linked it to the Alexa app. Final System Operation: The system is now operating pro

Upon arrival, I found the evaporator coil frozen. I returned to check the system pressures and verify proper operation. I turned the system on in cooling mode and monitored its performance. The system was operating and cooling properly at the time of inspection. The following readings were recorded: * Suction pressure: 120 PSI * Liquid pressure: 309.5 PSI * Superheat: 15°F * Subcooling: 11°F * Return air temperature: 75.7°F * Supply air temperature: 57°F * Temperature split: 18.7°F Based on these readings, the system is currently cooling within an acceptable range. Additional Findings and Recommendations: There is a high possibility that the previously identified maintenance and repair issues are contributing to the evaporator coil freezing up. The following work is recommended: 1. Remove the evaporator coil for a thorough cleaning. 2. Clean the blower wheel, which is heavily affected by debris. 3. Replace the pitted contactor. 4. Replace the capacitor. 5. Perform microbial sanit

Performed a diagnostic on a 4-year-old Goodman 3-ton straight-cool system with electric heat. I checked system operation in both cooling and heating modes. The system is currently operating in both modes. I checked compressor amperage, condenser fan motor amperage, blower motor amperage, electric heater amperage, refrigerant pressures, subcooling, superheat, and temperature split. During the inspection, I found the following issues: * Condenser coil is dirty. * Contactor is pitted. * Evaporator coil is dirty. * Debris buildup on the blower wheel. * Bacterial growth present on the evaporator coil and inside the air handler cabinet. * Drain pan is dirty. * Supply plenum has air leakage. Although the system is currently operational, it is not operating efficiently and is outside manufacturer specifications at this time. I prepared an estimate for the recommended repairs and cleaning services and presented it to the customer. The customer decided to keep the system as it is for now due

Performed a leak search on the newly installed Daikin system and found a refrigerant leak at the factory brazed connection on the liquid line. I documented the leak with a video showing bubbles during the leak detection process. I repaired the leaking connection by re-brazing it while flowing nitrogen through the line to prevent oxidation. After completing the repair, I pressure-tested the system and performed a vacuum, pulling down to 375 microns. I then released the refrigerant and added 6 pounds of R-32 refrigerant. After completing the repair and charging the system, I checked its operation. The unit is cooling and draining properly at this time.
