Frank's Air Conditioning performed some duct work, installed a better unit in my home, and they will be doing some further work for me. We arranged to do an air quality survey and they've given me advice as well.
I like that when I call them, I get a human to speak to promptly and they answer my questions. When I visit, they're always nice and courteous. Everyone is knowledgeable about what they do, even the young guys who come out.
