I also treated the drain line. The air filter was replaced with a client supplied filter. No major issues were found. The system was running at the completion of service.

Heat check completed on a horizontal gas system. Flame sensor was cleaned. Drain line was flushed and treated. I adjusted the gas pressure. No major issues were found. The system is heating properly at time of departure.

On arrival, I found that the system was not running with the thermostat on a call for cool. I went through the system and found that the run capacitor at the outdoor unit had failed across the HERM terminals. I went up into the attic and also found that the primary drain line was backed up and tripped the water safety switch. I installed a new outdoor run capacitor and new power surge protector at the outdoor unit. Installed all new wiring terminal connections and secured high voltage lugs. I cleaned and cleared the primary drain line and added in drain treatment solution to help ensure the system drains condensate properly from the evaporator coil to the downstairs bathroom sink. Cycled high voltage power to the system and checked over operation. Everything is working at this time.

Performed AC cool check. Checked the electrical, mechanical, safety, and performance of the system. I cleared the condensation drain line and flow tested the drain with two gallons of water. I also treated the drain line. The air filters had been recently replaced by the homeowner. At the condenser unit, I did find that the capacitor was below value. Options for repair were presented to the homeowner and Shaun chose to have the capacitor replaced and to sign up for our gold maintenance. I replaced the capacitor and function tested the system. The system is operational and was running at the completion of service. See attached tune-up checklist for additional details.

Installed new Lennox evaporator coil. Installed new liquid line filter drier in attic. Added extra foam block support on supply plenum. Sealed ductwork connections with mastic and hardcast. Pressure tested system with nitrogen and pulled vacuum. Cleared primary drain with CO2 and primed trap with water. Charged AC with R-410A refrigerant. Tested operation of system. Everything is working at completion of service.

Recovered refrigerant in the system. Replaced filter drier and replaced outdoor condensing coil. Pressure tested system and pulled a vacuum. Installed Surge Protector. Upon startup, realized compressor had shorted to ground. Recovered all refrigerant and replaced compressor. Pressure tested lineset and weighed in all new refrigerant and additional charge to meet manufacturer specifications. Everything is operational at this time.

Performed AC cool check. Checked the electrical, mechanical, safety, and performance of the system. I cleared the condensation drain line and flow tested the drain with two gallons of water. I also treated the drain line. The air filters were clean and had been recently replaced by the tenant. I cleaned the condenser coil. The capacitor on the condenser unit was below value. Options for repair were presented to the homeowner. He chose to have the capacitor replaced today. I replaced the condenser capacitor and function tested the system. The system is operational and was running at the completion of service.

Spoke with the homeowner when I arrived. On system startup the outdoor condenser would make a loud rattling noise but he figured it had something to do with the movers the day prior having the house open the complete day. We went outside to take a look at the unit and I pulled the disconnect. The condenser fan motor began to shake turning off. I installed the disconnect back in and did verify the rattling noise. Will need to install a new condenser fan motor at the outdoor condensing unit to return the unit back to designed operation. I went over repair options with the homeowner and he chose to have the condenser fan motor replaced. I installed a new condenser fan motor, programmed the motor for rotation and speed rating, and cycled on high voltage power. Checked over operations and verified everything was operating within manufacturer specifications for operation. Everything was working at completion of service.

After diagnosing system, I found the critical issue being the torque booster. I visited with the homeowner over the phone about options for repair. He has decided to become our newest maintenance member and have the torque booster replaced today. I replaced the torque booster and cycled both thermostats to verify proper operation. The system is cooling at time of departure.
