I have been using Peterson Heating & Cooling about eight to ten years and I have recommended them to other customers many times. Most recently they came by to do a maintenance cleaning on my system. They are very thorough and very neat in the work they do. They're also very good and they can locate problems almost before they happen. I'm very pleased with them. Their customer service is good. They're responsive and I've never had a long wait. They're just lovely folks to do business with and I'm very happy with what they do. I will continue to use them.
