Found 10 year old York a/c had no power going to outdoor contactor for first floor a/c. Came in side and reset the breaker. Outdoor unit came on. Found 410a system low on charge. Pressures were 325/110. Also had an 11 degree split at indoor coil. Told homeowner a few options. We can charge the system only. Second option we can add leak dye to find out where the system is leaking or we can replace the a/c. Customer decided to add refrigerant for now. Told homeowner that there is no guarantee on longevity of refrigerant charge and should probably start planning to replace the system. Added 1 lb 11 ozs of r410 a now pressures are 370/141 with a 18 degree split at indoor coil. System is working fine at time of service
