Tankless Water Heaters
As a Navien-certified installer, we also install tankless water heaters for homeowners who want continuous hot water and a smaller footprint.

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.
We offer a free diagnostic on water heater issues, so you know what’s actually wrong and what it will cost to fix before any work starts. Many installations and repairs are completed the same day when scheduled before 2pm, minimizing the time your household goes without hot water.

Choosing the Right Water Heater for Your Home
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.

Frequently Asked Questions
Should I repair or replace my water heater?
Start with our free diagnostic. We tell you what is wrong and what each option costs before any work starts. A tank that is leaking or nearing the end of its service life is usually a replacement, while a heater that is not heating properly can often be repaired.
Can you replace my water heater the same day?
Often, yes. Many installations and repairs are finished the same day when you book before 2 PM, so your household is not without hot water for long.
Tank, tankless, or heat pump: which should I choose?
A tank heater has the lowest upfront cost and the simplest install. Tankless gives you continuous hot water in a smaller footprint but needs the right gas line size and venting. A heat pump uses far less energy and may qualify for utility rebates. See current rebates.
What warranty comes with a new water heater?
Every installation includes a flat-rate quote before work begins, a 1-year workmanship warranty on our labor, and help registering the manufacturer’s product warranty. No fees are added once the job is underway.
Can I finance a new water heater?
Yes. We offer financing through Synchrony with $0 down and 0% interest when you pay the full balance within 6, 9, 12, or 18 months, so you pay exactly the amount on our invoice. You get the written price for the new water heater first, then decide how to pay. Subject to credit approval. See financing options.
