I contacted Aqua Systems and Texas Water Systems when my water softener was on the fritz. Of course, it was a holiday weekend. Since it was not a disastrous misfire, I contacted them by email. (There is an emergency contact provided.) Promptly Monday morning, I received a call from Steve. He arranged an appointment Tuesday morning and suggested I purchase the Coupon available on Angie's List to save money. The serviceman was right on time and patiently explained everything to me since I had a lot of questions. He was very efficient and quickly serviced the system. He even took off his boots after being in the yard to check the incoming water service. It is good to feel this confident that I will receive quality service. Any problem with a water system, Aqua Systems and Texas Water Systems will be my first call.
