Patterson Heating & Air Conditioning came and gave me a whole new AC system, and they were great. I had hired them, before, for other work, at my rental house, and then I hired them at my own home because they did just a fantastic job, the first time. They're honest people, and I feel very trusting of the company and confident in their work. I've never had any problems, and their work seems high-quality. They definitely deserve full ratings!
