“I had four well and water companies evaluate my well and home system that services a 4500 sq.ft. home, located smack on the Willamette River. I ended up installing a system that does not work well and asked DUO to re-evaluate and advise what might work. Thank God Aaron show up! I have never met anyone as glib and knowledgeable about well systems as “AARON AT DUO”! This guy is the real deal! Aaron has had years of both experience and education and understands the chemistry involved in water treatment. For instance, I didn’t know that acidic water wells should not be flushed/socked with bleach (as all the other companies recommended) because of calcium synergistics. Being able to talk with such a pro who understands the complexities and options involved in installing a whole house water system that actually works was so refreshing! I look forward to working with him. He didn’t try to sell me anything but expertly presented a whole house plan. His complimentary water tests and evaluation were comprehensive and reassuring. Thanks Duo!!”

“Christian was here to test our water quality and recommend treatment steps we could take in order to improve it. He was terrific, very knowledgeable and very friendly. He was also very communicative, during the period he was here as well as afterwards in regard to the estimate he provided and scheduling. I look forward to working with him on all our next steps.”

“Aaron arrived on time. Diagnosed my well issue, and answered all of my questions. Aaron is extremely knowledgeable about well systems. He gave me a few options to try to extend my pump life, along with an estimate for when the time comes to replace it. Great customer service. No high pressure sell at all. Truly wants to do right by the customer. I highly recommend DUO to anybody. Their customer service is unbeatable.”

“We had an appointment with Aaron today and we have to say, we're very impressed! He was thorough, knowledgeable and attentive to what we had going on. We never felt pressured to buy anything extra, and we did end up going with one of their quotes; it was reasonably priced! Their schedule was super fast too! We will call them for all of our well needs and will be calling for some upgrades in the future!”
