They did a great job. I hired them recently put in a new sewer system in my backyard, and everything is doing great. What I really like about Action Air is that they did everything they said they'd do, and I didn't encounter any surprises. Their technicians told me what was wrong and what it'd take to fix it. They dug up the whole backyard to install the sewer system, and the whole process ran efficiently and smoothly. When they arrived in the morning, they knocked in the door to let me know they had arrived. When they finished working in the afternoon, they knocked on my door again to let me know they were leaving. I thought that was a very courteous thing to do. When the city manager came from city hall to do the inspection, he said that the technicians from Action Air were the nicest people, and he asked me where I found them! They are good people, and they do good work.
