Yes — Cupertino is part of our regular Bay Area service area. We install and repair tank and heat pump water heaters throughout the city, from hillside homes to properties closer to the tech corridor. Call (408) 733-2000 to schedule a free consultation.

A metallic taste or smell in your hot water is usually a sign the anode rod inside the tank is corroding and needs replacement, or that the tank itself has started to rust internally. Left unaddressed, internal corrosion eventually leads to leaks. It’s worth having a technician inspect the tank rather than waiting for a bigger problem to develop.

Cost depends on the type of unit — standard tank or heat pump — along with your home’s plumbing and electrical setup. Rather than a rough estimate, we assess your home in person and provide a clear, itemized quote before any work is scheduled.

Rusty or discolored hot water usually points to corrosion inside an aging tank, or sediment being stirred up after a period of low usage. If it clears after running the tap for a minute, it’s often not urgent, but if it persists, the tank’s interior lining may be failing and replacement is worth discussing sooner rather than later.

Same-day service is usually available if you call earlier in the day. A lack of hot water is often a quick fix — a tripped thermostat or failed element — so odds are good it’s resolved on the first visit. Call (408) 733-2000 and we’ll get someone out to you.
