We had David from Pacific Water Conditioning to our house to service the filters on our five stage water conditioner. He was simply outstanding. I had thought that the filters were bad from a lack of water pressure in the system. David quickly determined that the problem was in the tank. Instead of attempting to upsale me, David told me exactly what he believed to be wrong, and was excited when the simpler fix worked. He tested our water quality, found that it was good, and only replaced what I asked. He was honest, was right on time, flexible to schedule, price was very fair, and his interaction with me as a customer was just spot on... We 100% recommend him. Will have him back again when it's time for new filters!
