Heat Pump Water Heaters

Heat pump water heaters use ambient air rather than gas or standard electric resistance to heat water, cutting energy use significantly. We provide heat pump water heater installation and heat pump maintenance, and can help coordinate utility rebate eligibility for qualifying installs.

Upfront Written Pricing and Warranty

Every water heater installation includes a flat-rate quote before work begins, a 1-year workmanship warranty on our labor, and support registering the manufacturer’s product warranty. There are no hidden fees added once the job is underway.

What Our Customers Say

Choosing the Right Water Heater for Your Home

Not every household needs the same type of water heater. We walk through tank size, fuel type, hot water demand, and rebate eligibility with each homeowner before recommending a system, whether that’s a straightforward tank replacement, a tankless upgrade, or a rebate-eligible heat pump unit.

What to Expect at Your Appointment

When you schedule an appointment, a licensed technician arrives during the agreed window, inspects your existing setup, and walks you through the available options before any work begins, backed by a flat-rate quote in writing so there are no surprises.

Permits and City Inspection

Replacing a water heater requires a plumbing permit, and the city inspects the finished installation. We pull the permit and install to the inspector’s list: seismic straps, relief valve drain line, venting, and gas connection. A straightforward gas tank swap is often done in one visit. A heat pump water heater takes longer, because the city approves the plan before install day. See how a gas tank installation runs and the heat pump installation timeline for each step.

Serving Sunnyvale and the South Bay

We install and repair water heaters throughout Sunnyvale and nearby Santa Clara, San Jose, Cupertino, and Mountain View. Contact us to schedule a free diagnostic, or ask about pairing a new water heater with a water softener to protect it from hard water.
