“I like that John Nugent & Sons comes when they say they're going to come. They do what they say they're going to do, and they do it well. They do air conditioning and furnace work. They installed the unit, too, so I have a contract with them—twice a year, they come in and service it. We had a neighbor who used them, and he recommended them. We had some other company that we were tired of using. Our neighbor recommended John Nugent & Sons, and we've been happy ever since. I'd give them an A.”
