Measured capacitance of compressor/fan motor capacitor. 5. Inspected and measured resistance of contactor 6. Measured compressor current draw. 7. Measured condenser fan motor amp draw. 8. Inspected and replaced return filter. 9. Inspected return plenum for dust or debris. 10. Inspected evaporator coil for cleanliness and oxidation. 11. Inspected blower motor/ blower wheel for dust and debris 12. Measured blower motor current draw. 13. Measured temperature differential from supply to return. 20 degrees measured. 14. Tested drain lines for proper drainage Outdoor electrical is all testing within manufacturer spec. Outdoor coils are extremely matted and dirty. This will cause an airflow restriction as well as block the heat exchange from happening efficiently. This causes stress on the refrigerant cycle and

Found leak in the evaporator coil. Client elected to have coil replaced under warranty.

I performed a single cooling maintenance on a 2020 dual fuel system. This system was brought into service in 2021. It is zoned and communicating. I checked amps, filter, electrical, cleanliness, and safeties. Due to the equipments past history, I advise adding a surge protector in the attic to prevent damage. I revisited the return cut in with the customer, and I offered to clean their filter.

Found outdoor unit with extreme amount of dust in debris coating the coils. After rinsing with water coils w

Upon arrival found the lennox unit to not be running. I proceeded upstairs where I found both the primary and secondary float switches to be tripped due to a clogged drain line. Presented issue to client. Client approved to have drain line and drain pan cleared of clog and water.

Tested temperature split and found supply only around 58-59. Tested refrigerant pressures and found system to be low. Found leak in the evaporator coil for master bedroom. Advised homeowner it was covered under parts warranty the only things he would be responsible for are refrigerant, new filter dryer, and labor. Office sent error to me that I was not seeing on this unit found den unit displaying error for amient temp sensor. Reviewed outdoor wiring and found sensor chewed by rodents. Measured ohms and found OL indicated the wire is severed somewhere. Provided options to homeowner for coil replacement and sensor replacement. Both systems running upon departure

.

5/21 - I returned to install a surge protector. The surge protector is installed and active. The system is operational upon departing. 3 year warranty / up to 10,000.00 coverage if part fails to protect the connected equipment. (Warranty is through manufacturer)

I performed a single cooling maintenance on a 2020 Daikin mini split. I thoroughly examined cleanliness, operation, drains, and electrical. During my drain testing, I discovered that the unit drips water from the bottom right corner when too much water is present. I quickly investigated and found that the drain pan is cracked. To properly address this, we need to remove the evaporator coil to replace the drain pan. Customer decided that it currently was not a big enough issue to proceed with a repair. I noticed that the equipment does not have surge protection. Mini splits are very susceptible to surge damage. I offered to install a surge protector at the time of service.
