Gas Water Heaters
Gas Water Heater Installation, Repair & Replacement
Fast, code-compliant gas water heater replacement.
Overview
What to expect.
When a gas water heater fails, you want hot water back fast. Green Core Heating & Air replaces and repairs gas tank water heaters for homes in Petaluma, Santa Rosa, Rohnert Park, Novato, San Rafael, and across Sonoma and Marin counties. Same-day water heater replacement is available when our schedule allows.
We install Bradford White and American Standard gas water heaters, sized to your household. A typical home uses a 40- or 50-gallon tank, and we'll confirm the right size before we install.
Every install is done to California code: seismic strapping, a properly piped temperature and pressure relief valve, correct venting, an expansion tank where required, and a permit. Those details matter for safety and for your home's resale.
Thinking about going electric? A heat pump water heater can replace a gas tank, costs less to run, and usually qualifies for rebates. We're happy to price both options so you can compare.
Gas tank water heater installs start at $2,850. You'll get a clear written price before any work starts.

FAQ
Frequently asked questions
How long does a gas water heater last?
Most gas tank water heaters last about 8 to 12 years. Leaks from the tank, rust in the water, or popping and rumbling noises are signs it's near the end.
Can you replace my water heater today?
We offer same-day replacement when our schedule allows. Call (707) 988-5858 and we'll let you know the earliest we can be there.
What size water heater do I need?
Most homes use a 40- or 50-gallon tank. Larger households or big soaking tubs may need more. We'll confirm the right size before installing.
Do I need a permit to replace a water heater?
Yes. In California, water heater replacement requires a permit and seismic strapping. We pull the permit and install to code.
Should I replace my gas water heater with a heat pump?
It's worth considering. A heat pump water heater costs less to run and often qualifies for rebates. It does need an electrical circuit, so we check your panel and price both options.
What brands do you install?
We install Bradford White and American Standard gas water heaters.
