Water heater repair
& installation in Mesa.
No hot water, a leaking tank, or a heater past its prime — we repair, replace, and install tank and tankless systems the same day, with a flat-rate price before any work begins.
Full-service water heater care for East Valley homes.
Your water heater works harder in Arizona than almost anywhere else — hard water scales up tanks, sediment settles fast, and a unit that quits on a summer weekend never picks a convenient moment. OX Plumbing repairs, replaces, maintains, and installs water heaters across Mesa, Gilbert, Chandler, and the East Valley, so hot showers come back the same day you call.
We service gas and electric systems from every major brand, and we're straight with you about the repair-or-replace question: if a fix will genuinely carry your unit for years, we say so. If you're pouring money into a tank at the end of its life, we'll show you the numbers and let you decide — no pressure, no upsell.
Thinking about going tankless? We install wall-mounted, on-demand systems that free up storage space, deliver endless hot water, and typically outlast a traditional tank by a decade.

Why waiting on a water heater costs more.
A struggling water heater rarely fails gracefully. Small symptoms — a longer wait for hot water, a faint rumble, a damp spot near the base — escalate into a burst tank, and a burst tank means water damage, an emergency replacement at emergency prices, and days of disruption.
Handled early, the same problems are routine: a flush, an element, an anode rod. That's the difference between a scheduled visit and a 2am phone call — and it's why we tell every customer that the cheapest water heater repair is the one you don't postpone.
