Arrived to system in a hard lock out. Cycled power and turned system on found system is low 2-3lbs of R410A. System will not cool at this time due to system being low on refrigerant. Will need to leak search system to locate leak and then repair. System is 7 years old warranty expired in 2023. Spoke with homeowner and she decided to wait. Spoke with Kieth about the 5 year warranty he said we need to double check that it isn’t supposed to be a 10 year warranty and then will let homeowner know.
