SIGNS YOUR WATER HEATER NEEDS REPAIR
Water heaters rarely fail without warning. Here are the problems San Jose homeowners call us about most often:
No Hot Water, Or Not Enough Of It.
If your water heater isn't producing hot water at all, or runs out faster than it used to, something's wrong. It could be a failed heating element, a faulty thermostat, or sediment buildup blocking the tank. Ignoring it won't make it better, and cold showers get old fast.
Strange Noises From The Tank.
Rumbling, popping, or banging sounds usually mean sediment has accumulated at the bottom of your tank. San Jose's moderately hard water accelerates this buildup. As sediment hardens, your water heater works harder, drives up your energy bills, and moves closer to failure.
Leaks or Water Pooling Around The Unit.
Even a small leak can signal a serious problem, a corroded tank, a failing pressure relief valve, or loose connections. Water damage to your garage, utility closet, or home adds up quickly. If you see water around your unit, don't wait to call.
Rusty or Discolored Water
When hot water comes out brown or rust-colored but cold water runs clear, corrosion inside your tank is likely the culprit. Left unchecked, that corrosion leads to leaks and eventually complete tank failure.
If any of these sound familiar, it's time to call a professional. The longer you wait, the more likely a repair turns into a replacement.
Our Water Heater Repair Process
Here's what you can expect when you call us out.
Accurate diagnosis first
Our technicians don't guess. We thoroughly inspect your entire water heater system, tank or tankless, to identify exactly what's causing the problem. We check thermostats, heating elements, pilot lights, gas valves, pressure relief valves, and anode rods. You'll know what's wrong before any work begins.
Upfront pricing, no surprises
Before we start any repair, we explain what needs to be done, what it will cost, and the multiple pricing options we create for you. No hidden fees, no pressure. You approve the work, or you don't pay for a repair you didn't authorize.
Quality parts and expert workmanship
We repair all major brands, including A.O. Smith and Rinnai. Our technicians carry common replacement parts on their trucks, which means most repairs are completed in a single visit.
Tank and tankless expertise
Traditional tank water heaters and tankless systems fail differently and require different repair approaches. Our team has extensive experience with both hot water heater repair and tankless water heater repair, we've seen it all and fixed it all.
Same-day service when you need it
Not having hot water disrupts your entire day. We offer same-day appointments for emergency water heater repair so you're not stuck waiting days for a technician while being forced to shower at the gym.

FAQ
How do I know if my water heater needs repair or replacement?
Generally, if your water heater is under 10 years old and the repair cost is less than half the price of a new unit, repair makes sense. If it's older, has a history of problems, or the tank itself is leaking, replacement is usually the better investment. We'll give you an honest assessment, and will not push a replacement if a repair will solve the problem.
How long does a water heater repair take?
Most repairs are completed in one to two hours. If we need to order a specific part, we'll let you know upfront and schedule a follow-up visit as soon as it arrives. Our trucks are stocked with common parts, so same-visit repairs are typical.
Do you repair both tank and tankless water heaters?
Yes. Our technicians are experienced with traditional tank water heaters and tankless systems from brands like A.O. Smith and Rinnai. The diagnostic process differs between the two, but we're equipped to handle both.
Why is my water heater making noise?
Popping, rumbling, or banging noises usually indicate sediment buildup at the bottom of the tank. San Jose's water is moderately hard, which accelerates mineral accumulation. A professional flush can often resolve the noise and improve efficiency. If the sediment has hardened significantly, other repairs may be needed.
Can I repair my water heater myself?
We don't recommend it. Water heaters involve electricity, gas, high temperatures, and pressure—all of which can be dangerous if handled incorrectly. A licensed plumber can diagnose and repair issues safely while ensuring the work meets local codes.
Do you offer emergency water repair?
Yes. We often can provide same-day service for water heater emergencies. If your water heater is leaking, completely failed, or creating a safety hazard, call us immediately at (408) 898-2500. Our emergency line is answered 24/7 to schedule priority service.
