Water Heater Service in San Jose

Repair, replacement, tankless conversions, and the hard-water maintenance that decides how long a tank lasts here.

CSLB #723684 · 24/7 emergency service

San Jose water is hard, and hard water is what kills tanks. Sediment settles on the bottom, the burner has to fire through it, and that is the rumbling people describe on the phone. We repair what is worth repairing, replace what is not, and tell you plainly which one you have, even when the answer is that you do not need a new tank yet.

What water heaters work covers in San Jose

Water Heaters in San Jose

No hot water? Rusty water? A tank that is leaking or past its 10 to 12 year lifespan? We repair and replace gas, electric, and tankless water heaters, haul away the old unit, and make sure everything is up to California code, including seismic strapping. More on water heaters in San Jose.

Water Heater Repair in San Jose

Not every water heater problem is a new water heater. If the tank is under about eight years old and a single part has failed (a thermocouple, heating element, thermostat or relief valve), a repair is the right call and the parts are inexpensive. We diagnose before quoting. If what we find is a tank that has rusted through, we will say so instead of selling you a repair that buys a couple of weeks. More on water heater repair in San Jose.

Water Heater Replacement in San Jose

Past ten years, leaking from the body of the tank, or rusty on the hot side, and replacement is the better spend. A like-for-like swap is usually a couple of hours once we are on site. What stretches it is access and old valves. A heater standing clear in a garage is straightforward; one in a closet that has to come out sideways past a washing machine is not. A shut-off valve that has not been turned in decades sometimes will not seat again once it has. More on water heater replacement in San Jose.

Tankless Water Heater Installation in San Jose

Hot water that does not run out, and a unit that should outlast two tank heaters. The catch is that the unit is the cheap part of the job: many houses need the gas supply upsized and new venting run, and that work does not appear in the price on the box. Our hard water also means a tankless needs descaling periodically or it slowly loses efficiency. We quote tank and tankless side by side so the comparison is real.
