Performed cooling maintenance on two systems. Checked electrical, mechanical and performance of the systems. Cleared and treated both drain lines and washed both outdoor coils. I found that the system on the main house has a dirty blower wheel, and the starter at the condenser is burnt and pitted. I also found that the condenser fan motor for the guest house system is leaking lubricant. No other major issues were found. Both systems are operational at this time.
