Tankless Water Heater Installation, Repair & Maintenance

Tankless heaters heat water on demand, so you don't run out and you get back the space a tank takes up. We install, repair and maintain them.

Why homeowners switch to tankless

  • Hot water on demand, without waiting for a tank to recover
  • A wall-mounted unit frees up floor space
  • No standing tank of water kept hot around the clock
  • A long service life with regular maintenance

How we handle it

Size it right

We size the unit for your peak hot water use, so it keeps up when two showers run at once.

Check gas, venting and power

Tankless units often need a larger gas line, new venting or a dedicated circuit. We check before you commit.

Install and walk you through it

Installed, tested, and set up with you before we leave.

Tank or tankless for your house

Tankless suits a lot of Bay Area homes but not all of them. We check the gas line, venting and space before you decide.

Still deciding? Our water heater page covers repairs and tank replacements, and a heat pump water heater is the third option.

Tankless repairs

Most tankless problems show up as an error code. They usually come down to ignition, flame sensing, venting, water flow or scale. Tell us the brand, model and code when you call so we come with the right parts. The Navien install above is a typical setup: wall-mounted, with its own PVC venting and shut-off valves on the water lines. If the unit is near the end of its life, we will say so and give you the cost of a replacement next to the cost of the repair.

Questions we hear

Is a tankless water heater worth it?

For many households, yes: continuous hot water and more space. Installation costs more than a like-for-like tank swap, especially if the gas line or venting needs upgrading. We will give you the full picture before you decide.

How often does a tankless heater need maintenance?

Most manufacturers recommend flushing the unit about once a year to clear mineral scale. Hard water can mean more often.

My tankless heater shows an error code. Can you help?

Yes. Error codes point to the problem, such as ignition, venting or water flow. Tell us the brand and the code when you call so we come prepared.

Do you repair Navien, Rinnai and Noritz tankless heaters?

Yes. Those are among the brands we work on, along with Rheem, Bradford White and A.O. Smith. Have the model number and any error code ready when you call.

Is there a discount on a tankless install?

Yes. Switching to tankless is $300 off right now. Rebates, where a program offers one, are separate. Mention it when you book.
