One system heat maintenance in Flowery branch. Arrived on site, cleared barometric ports, checked ignition systems, electrical connections, amp draw and capacitance. Found outdoor unit fan motor drawing higher than normal amp as well as a burnt and pitted contactor. Recommended replacing these parts as well as adding surge protection to both pieces of equipment to protect electrical systems from surge and an attic tent for the attic stairs to prevent heat transfer into unconditioned space. . Unit is operating normally at this time.
