Upon arrival the battery's in the thermostat was dead the system was turned off. Replaced customer supplied battery's. Turned system to cooling and made sure that system was working properly and the refrigerant levels where good. While inspection of the attic I located exposed wires need to be put in a junction box, this is a fire hazard, also found on cust panel it is exposed and someone could easily be shocked, going to put covers on panel. Cust has florescent lights outside that are burnt out, cust wants Me to change bulbs, explained to cust that we will likely have to change the fixtures due to them being old and not having secure connections. Wants to try changing bulbs first if this doesn't work we will change fixtures. Need to return first call Thursday the 25th I will gather parts
