Performed pm on all 6 units. Replaced provided filters. Flushed drains out with brush and hot water. Tested condensate pumps. Checked cleanliness of coils and blowers.

Also quoting customer to install media filter in cottage, only system using 2inch filters, 24x28x2.
There was evidently a power surge. Upon arrival I found burnt wires coming from the main system contactor. The blower would not operate. I told the customer I would need to repair these before I could test the unit. Once the burnt wires were replaced the blower was the only thing that worked. The zone board is corrupt as well as the 2 boards in the unit that operate the compressors. I tried to get the unit to run on auxiliary heat but the zone board despite having inputs from each Tstat would never energize the auxiliary heat contacts. I manually jumped them out and the auxiliary heat did operate. I could not leave it jumped out because it would never turn off. I made an estimate to replace the main zone board and the two boards that operate the 2 compressors. I took pictures of the parts. Customer needs to contact insurance before approval of the repairs. Customer paid for the burnt wires to be fixed. I would suspect a surge from a storm damaged the electronics.
