Best Surge Protection in Charlotte NC

Technician was thorough and isolated the problem through process of elimination. What we thought was a problem indoors actually turned out to be an outdoor problem.

Came out and serviced AC that was not cooling. Said it needed Freon. Paid $950 for service. They left and AC still isn’t working. They came back out and said I need a new coil $2,800 plus labor. However, they are out of Coils so since it is August I should buy a &13k air conditioner. Unethical and a rip off!!! Stay far away!!
