Arrived on site, customer stated they were not having any issues or concerns. Found bad fan capacitor in up stairs office furnace. The remaining furnaces were testing within manufacture. Found bad fan capacitors on both 5 Ton condensers as well as high start amps (150). All contractors were testing within range. Washed all outdoor units to assist with unit efficiency. Noticed thermostat wire on one of the garage units had exposed wire. Appears to be due to sun exposure. Recommended to customer to replace the bad capacitors and install hard start kits to extend the life of the over amping condensers. Customer went ahead with estimate. Replaced all bad capacitors and repaired damaged thermostat wire. Scheduled return visit to install hard start kits. All units in working order upon departure.
