Lukewarm showers? Popping sounds from the tank? A tankless unit that keeps cutting out? In Austin, those aren’t just annoyances—they’re signs your water heater needs attention from a team that knows our city’s water and homes. Since 1999, Radiant Austin has restored hot water for families and small businesses across town, pairing fast response with plain-English explanations and up-front pricing. We troubleshoot first, repair when it makes sense, and only recommend replacement when it’s truly the smarter move.
Here’s what we see locally. Austin’s hard water leaves heavy mineral deposits that settle in tank-style heaters and clog heat exchangers in tankless systems. That buildup steals efficiency, overheats parts, and shortens equipment life. Our techs flush tanks, descale tankless systems, check anode rods, and verify expansion control so your heater runs safely and reliably. In many neighborhoods, water heaters live in hot attics or garages – tough environments that accelerate wear on valves and sensors. We test safety devices and venting so you can count on consistent, safe hot water. Cold snaps can also stress older tanks and outdoor piping; if a relief valve is dripping or you suspect a small leak, we stabilize the situation and prevent bigger damage. For small businesses, we schedule around your busy hours and keep the work area neat so you can keep serving guests.
If repairs will only kick the can down the road, we’ll walk you through right-sized options for Austin’s water conditions, such as tank versus tankless systems, along with maintenance plans that actually prevent repeat problems. No pressure, no surprises, just clear choices.
