Be very careful when weedeating around your air conditioning unit. It is possible to cut a wire which will render your unit useless. This will cause a repair that will be very complicated. Much troubleshooting and sweating in the land. God might possibly have mercy on your soul and send a stormy day breaking the heat a bit, but it will still be a hot and sweaty day. Attics are no fun on those days.
I would love to post more, but as I am hotter than a $2 pistol, I shall stop now!!
