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.

Performed a diagnostic on the downstairs Goodman unit, approximately 9 years old. Found the system drain line clogged, causing the safety float switch to fill with water and interrupt the thermostat voltage as a safety precaution. Contacted Paul and received approval to perform the drain cleaning. Cleared the drain line and flushed it with approximately 6 gallons of hot water until the water ran clear. Cleaned the drain pan and applied Viper treatment. After completing the drain cleaning, I tested the system operation and confirmed the unit returned to cooling mode. I also inspected the electrical components. The capacitor was within manufacturer specifications; however, the condenser contactor was badly pitted. Contacted Paul again and received approval for contactor replacement. Replaced the contactor and tested the system again. The system is cooling and draining properly, and all components are operating normally at this time.

Performed a diagnostic due to the drain line overflowing and activating the safety float switch. The customer showed me water trapped inside the return duct. The system also has another drain trap installed underneath the slab with a vent pipe. The customer reported attempting to clear the drain line multiple times, but the issue continued. I ran a drain snake through the line from outside to inside and from inside to outside. I found debris and significant algae buildup inside the drain line. When testing drainage directly from the drain pan, I noticed that the water was still overflowing. I then cut the drain line near the drain pan and identified a blockage. I cleared the blockage, cleaned the drain line, and reconnected the piping using PVC glue. I flushed approximately three gallons of hot water through the drain line until the water ran clear. A significant amount of algae and debris was removed. I also cleaned the drain pan and applied Viper drain treatment. After completing

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
