Repair & Maintenance


Not every problem needs a new unit. If you have lukewarm water, a pilot light that won't stay lit, or a popping noise (sediment buildup), we can often repair it. We replace heating elements, thermostats, and thermocouples to extend the life of your current water heater.





Frequently Asked Questions


  • How much does a water heater replacement cost in San Jose, CA? Cost varies by size and type (gas vs. electric). We provide a flat-rate quote that includes the unit, installation, parts, and disposal of the old tank.
  • Why go tankless? Tankless units save space (wall-mounted), last longer (20+ years), and reduce energy bills because they don't heat water when you aren't using it.
  • What causes a water heater to leak? Usually, it’s the steel tank rusting through after the anode rod has been depleted. Once the tank rusts, it must be replaced.
  • Do you install electric water heaters? Yes. We install electric tanks and high-efficiency hybrid heat pump water heaters, which are great for all-electric homes.
  • How long does installation take? A standard swap takes 2-4 hours. A tankless conversion is a bigger job, typically taking a full day due to gas and vent work.
