I had an issue with our upstairs AC unit. It wasn't blowing out any cool air. There was water build up in the pipe. At that time, my wife was about eight months pregnant and she was hot and upset. I searched online and found Hixon Heating & Air Conditioning. I thought they had a very professional website so I gave them a call. They came out on a weekend at six at night. They fixed the problem and didn't charge me the overtime weekend price! I'll definitely use their services again in the future.
