I was referred to AOS, and it's the best one I've ever had! Replaced my failed home sewage pump on the same day in record time. With competitive costs and great service, I'll never use anyone else. A true "customer service" business!

We have used these guys a few times over the years. This last experience was even better than the great service we’ve had in the past.I briefly explained my problem, they worked out a schedule to be here the next day.Amanda was great, but I have to give a huge thanks to Josh. He remembered us from a few years past, identified my issue quickly and gave me great advice to solve it quickly to avoid bigger issues later.I highly recommend them!!Thanks again.Chad BurnettNewberg

So grateful to Jim & John who came to the house. The lady on the phone listened, asked a few questions about the clean out pipe and yard. Drains had been working all day then did a load of laundry in the evening and suddenly everything is backing up. We made a few calls around immediately the next morning when it was obvious we couldn't clear it ourselves. American came to the house a few hours later, friendly, helpful, didn't just do the job but took the time to review out septic maintenance practices so they could get a good idea of how it may be flowing, or not, and why. Got the clog cleared and came in considerably less $ than I expected to pay. Definitely will call them again, just hopefully not too soon. Thank You!
