Hard water is a fact of life in San Antonio—and it takes a toll. Scale buildup in pipes and fixtures, cloudy dishes, itchy skin, worn-out appliances… it all adds up. At Radiant Plumbing & Air Conditioning, we help San Antonio homeowners take control with professional water softener system installation and repair.
Whether you’re installing a new system or maintaining an old one, our licensed plumbers will help you choose the right solution for your home’s size, plumbing setup, and water usage. We work with trusted brands, offer upfront pricing, and ensure every install is done right the first time.
And we don’t stop at install day. We’ll walk you through how your system works and how to maintain it—so you enjoy cleaner dishes, softer laundry, and longer-lasting plumbing from day one.
When you’re ready to take the hard out of your water, just call Radiant.
Water softeners work quietly in the background—but like any home system, they need proper maintenance to keep doing their job. That’s where the Radiant Care Club comes in. As a member, you get an annual plumbing inspection from a licensed pro who knows what to look for, including signs of resin wear, valve issues, salt bridging, or early leaks.
We’ll help you catch minor problems before they turn into major water quality issues or system damage. If repairs are needed, you’ll get priority scheduling, no dispatch fees, and 10% off your service. Whether you’ve just installed a new softener or are keeping an older unit running, Care Club membership helps extend the life of your system and keep your home protected from San Antonio’s notoriously hard water.

San Antonio’s hard water is no small challenge. Fed by the limestone-rich Edwards Aquifer, it leaves its mark everywhere—on your dishes, laundry, skin, and the lifespan of your plumbing fixtures and appliances. At Radiant, we take pride in helping homeowners protect what they’ve built. Our team installs dependable water softeners designed to match your home’s plumbing layout, daily use, and long-term needs. Every job is completed with code-correct craftsmanship, honest communication, and transparent pricing—values we stand by.
Local experience matters. Many San Antonio homes include a garage softener loop with power and drainage nearby; if yours doesn’t, we’ll create one and add a proper air gap to prevent backflow. For homes with tankless water heaters, we often pair softeners with sediment pre-filters and service valves for simple maintenance and longer system life. When pressure-reducing valves are in place, we inspect or install thermal expansion tanks to keep your softened system and water heater running safely and efficiently. Outdoor setups get UV-resistant covers and freeze protection—because anyone who’s been through a Hill Country cold snap knows it’s better to be prepared.
We size every system by grain capacity and flow rate, so your showers stay strong even when the laundry and dishwasher are running. Prefer something low-maintenance? Our demand-initiated softeners regenerate only when needed, saving salt and water during drought seasons. And for small business owners, we design commercial-grade solutions that protect ice machines, espresso makers, and combi-ovens—keeping warranties intact and water quality consistent.
At Radiant, our approach is simple: we treat your home like our own, with respect, precision, and pride in every detail.
