"This was a complex retrofit tankless water heater installation and out of 30+ companies called and solicited for this project, Brett and Dunn's HVAC was the only company to 1) entertain performing the installation correctly (gas line sizing and calculations), 2) had prior experiencing working with tankless heaters, and 3) took the time to work with me on a long list of specifications. These are bulletproof systems if the installation is done correctly and Dunn/Brett took the time to ensure the install was on point and everything went smoothly. They also installed a softener and filtration system. Everything went well from bid to install and I highly recommend Brett and Dunn's - will use again as I could not be more pleased!"

"I hired this company to extend the natural gas in my house and would definitely recommend them. I felt that the plumber who did the installation really knew what he was doing and seemed like a great guy. The installation went well and the price was fair."

"This is a good company to deal with. James, the owner, was out within one hour to diagnose our problem. The next morning the technicians, Brian and Josh were out to take care of our drain issues. Brian made a point of showing me the camera footage of the main drain. The did a great job on the main and two other drains. They also cleaned up very well when they were done. Brian also noticed an issue with our bathtub stopper and fixed it without an extra charge. The pricing was transparent. They have a nice email notice system and called when they were on the way. The three men I worked with were all very professional and easy to deal with. I would not hesitate to use them again. Phil Lykens"

Small jobs welcome

Hello,\nI’m Brian and have been an electrician for 35 years and over the years I have learned other trades and I just understand building and mechanical items and how they work. That promotes the way I take things apart and how they go back together. I look forward to working with you to start and/or complete unfinished projects.

"Mayo Plumbing is different from all the rest. They use data and research to inform their work. Before calling Mayo I had two different plumbers look at our new (very old) house. The first said, "St. Louis has hard water - you NEED a water softener." The second said, "St. Louis has great water - you DO NOT need a water softener." Mayo said, "What did the test results say? No one can tell you you need a water softener without testing your water first." BINGO. They tested our water and determined we DO NOT need a water softener. Same approach for our broken shower. The mayo plumber actually researched the issue, spending time with the paperwork and on the phone with the Kohler rep to determine exactly what we need to do, before making a wild guess and upselling us. I've never seen a plumber like this - these guys are SMART and will be our go-to provider!"

"It was very good. My husband was there when they came. I think they were just professional and reasonable. They did the dryer vent. I wasn't there when it was done but I think my husband was pleased with their professionalism and performance. We would absolutely use them in the future."

Water Softeners FAQs, answered by experts

You can decide whether you need a water softener or water filter based on how your bathing or laundry experience is. If you notice issues like limescale buildup, dry skin, or stains on dishes—all telltale signs of hard water—you'd likely benefit from a water softener. However, if your main concern is over chemicals or bacteria in your tap water filter, and not just comfort, a filter is a better option.

Installing a water softener could help reduce calcium buildup in your pool if your pool has high calcium hardness as a result of hard drinking water in your home. Pool softeners work by exchanging calcium and magnesium for sodium, so if you use softened water to top off your pool, it may help keep calcium hardness from rising over time. However, it won’t lower the calcium hardness of the water already in your pool and isn’t a practical way to control pool calcium levels. The average water softener installation cost is between $200 and $6,000.

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.

While it depends on how complicated the unit and installation is, it takes two to four hours to install a water softener unit, on average. It might take longer if pipes need to be replaced. You should make sure the installation area is clear of any objects that might get in the way before you begin.

Soft water is better for your hair. The minerals in hard water can dry out hair, make it brittle, and leave a film on the hair and scalp that may cause irritation. Hard water also doesn't rinse out shampoo and conditioner effectively, which can lead to product buildup that makes hair look dull and limp. You may also find you need to use more shampoo to get a good lather in hard water.
