Recovered the refrigerant from the condensing coil. Flowed nitrogen through the refrigerant lines during the installation process. Installed a new Teflon gasket and completed brazing with nitrogen flowing through the lines to prevent oxidation. Performed a pressure test at 350 PSI to verify system integrity. Once the pressure test was completed, evacuated the system to 360 microns. Released the refrigerant back into the system and added 5 pounds of R-410A. Started and tested the system operation. The unit is cooling properly and the condensate drain is draining properly at this time.

Performed preventive maintenance on the pool heater heat pump. Checked system operating pressures, contactor, capacitor, and temperature split between the pool water and evaporator coil. Verified that the capacitor is operating within the manufacturer’s specifications. Inspected and rinsed the condenser coil to remove accumulated debris. Tested overall system operation and confirmed that the pool heater is operating properly at this time.

Performed preventive maintenance under the maintenance contract on the gas furnace. Tested system operation in heating mode and found the furnace operating properly. However, I noticed the unit is equipped with a two-stage gas furnace, but only the low stage is currently connected and operating. The W2 wire is not connected, preventing the furnace from operating in high-stage heating and reaching its full heating capacity. I brought this issue to the customer’s attention and explained the importance of connecting the W2 wiring and programming the thermostat for two-stage operation. I offered to have the wiring connected and the thermostat properly programmed, but the customer declined the recommendation at this time. I also tested the system in cooling mode and confirmed proper operation. Checked compressor amperage, condenser fan motor amperage, and indoor blower motor amperage. Capacitor readings are within manufacturer specifications, and the contactor is in good condition. Addit

Performed a system diagnostic and found the condensate drain line extremely clogged. I cleared the blockage by running a drain snake from inside to outside and outside to inside. I then applied Drain Solve and allowed it to sit for 15 minutes to break down the buildup. Afterward, I flushed the drain line until the water ran clear. The drain pan was clean; I brushed it and applied Viper drain treatment. I also flushed the drain line with approximately 6–8 gallons of hot water. Finally, I tested the condensate drainage and confirmed proper water flow. The system is draining properly and cooling at this time.

Performed a diagnostic on a 23-year-old Thermo-Start heat pump system. The unit was calling for cooling but operating in heating mode. I checked the reversing valve wiring from the thermostat to the outdoor unit and confirmed that the reversing valve signal was energized. However, when checking the output from the defrost control board to the reversing valve solenoid, I measured only 3.2 volts instead of the required 24 volts. While inspecting and manipulating the board terminals, I noticed that the system switched back to cooling mode. This indicates an intermittent issue with the defrost control board, potentially caused by a loose terminal, damaged terminal connection or mounting support, or a faulty board relay. The control board is not field-repairable, and replacement of the defrost control board is required to address the issue. I explained to the homeowner that the replacement board may still be available but would likely need to be special-ordered due to the age of the equi

Performed a diagnostic on a 3-ton Goodman air conditioning system. Upon arrival, the indoor blower was running and the thermostat was calling for cooling. The outdoor contactor was pulled in, but the condenser was not operating. Electrical testing revealed no 240 volts line-to-line or 120 volts line-to-ground. Upon further inspection, I found the condenser breaker in the OFF position. After turning the breaker ON, the outdoor unit started operating. I connected my refrigerant gauges and found the system extremely low on refrigerant, with a suction pressure of 36 PSI. As a complimentary service, I performed a visual inspection and electronic leak search on the evaporator coil. I observed oil staining on the coil, and the electronic leak detector confirmed a refrigerant leak. I contacted the office, and a call was created for Kenneth to assist with preparing a new equipment proposal. The customer also approved adding 3 pounds of refrigerant to provide temporary cooling while deciding b
