"Kayvan was a wonderful service tech! He was on time and professionally checked out the water heater and the HVAC system. He was so polite and friendly. He explained the need for a new filter in the heating unit and showed me photos of the unit located in the attic. He also offered to do a friendly deed for free, which I greatly appreciated, He’s a great asset to Service Champions!"

"After speaking with Kevin (CEO) about the merits of the One Water System, and my own online followup, I bit, and was scheduled for installation 5 days later. Juan, the installer was on time, courteous, self-effacing, humorous, knowledgable and highly skilled. He replaced the ugly functioning plumbing (piping) with a more contoured professional appearance. After the system instalation, function test, old water softener packed and area cleaned. I was given an outline of positives results to look for.  And, as of 2 weeks after installation, I am very pleased with results. Faucet run faster, wife says hair and skin feels better. Good professional results from beginning to end.

"Called AYS Plumbing for a water heater install. The service tech Mike Garcia was very prompt and very professional. He explained what he was going to do and what it was going to take to get the job done. Mike cleaned up after himself and also got rid of my old water heater. Definitely will be using AYS for my future plumbing needs. Mike Garcia was very professional and very knowledgeable. Thanks again Mike, 10 starts from me!!!!!"

"We have a leaking water heater which happened on a Saturday morning.   We talked to a nice lady named  Jaye who was patiently listening to our problem that  we urgently needed someone to come out to fix the problem.  Jaye tried her best and she was able to send Brian to help out by replacing the water heating  in the afternoon.  Brian did a good job replacing the water heater and removing the old one.  Overall,  I am very happy with the service and I will use them again in the future.

Water Softeners FAQs, answered by experts

Yes. Hard water is what causes scale buildup, and a whole-house filter provides numerous benefits beyond water softening. Any water that enters your home will go through the filter, which cleans up all water that you will use for cooking, bathing, and drinking. A whole-house water filter also blocks harmful particles like heavy metals.

A single shower consumes an average of over 17 gallons, while brushing your teeth with the water running uses up to four unnecessary gallons. Watering the lawn spreads hundreds of gallons of water across the yard each time. Limiting water usage in these areas can significantly cut down your water bill.

You can install a water softener system by turning off the water supply, draining the water, and then connecting your device to the waterline. Next, you’ll fill your tank with the recommended amount of salt or brine (whichever your unit calls for; be sure to read the instructions). Turn the water supply on and check for leaks. You can opt to let your water run for a few minutes, then test it using strips. 

The process of inspecting your water softener system is similar.

Yes, a water softener can remove scale deposits. According to the U.S. Department of Energy, after you add a water softener to your home, “gradually the softer water will dissolve limescale scale deposits and remove the problem entirely.” Installing a water softener—or water descaler—will also help prevent new scale deposits from forming.

Whether you need a permit or license for a water softener installation depends on your location, as requirements vary significantly. Some municipalities require the installer to hold a plumbing license, some mandate a permit and an inspection, and others require both. In some areas, no special permit or license is needed at all.

To determine the rules in your area, you can contact your local building department or consult a local water softener installer or plumber. Often, only certified professionals are authorized to pull the necessary permits, and they will typically handle the entire permitting process for you. Regardless of local laws, it is always recommended to hire a licensed professional to ensure the system is sized and installed correctly. You can use Angi’s state licensing tool to check an installer’s license status.
