The air conditioning unit in our upstairs bedroom was freezing up, so we reached out to Sig Cox Augusta Heating and Air Conditioning for assistance. Their worker came out on time, put more Freon in the unit, and did a great job. He was very professional and respectful of our home. I've been using Sig Cox for two years now, and they have always done a good job. They show up when they say they will, and never make stuff up in order to sell us a product we don't need; they're very honest.
