Gas and electric tankless installation, repair and maintenance. Authorized Rinnai dealer — save up to $2,200 on a new residential install.

Tankless Water Heaters: common questions
Does a tankless heater need maintenance?
Yes. LA's hard water leaves scale inside the heat exchanger, so we recommend descaling about once a year to keep efficiency and warranty coverage.
Can my home switch from a tank to tankless?
Most homes can. We check your gas supply, venting route and water pressure on site before recommending a model.
Do you install electric tankless water heaters?
Yes — we install and service both gas and electric tankless units. Electric models need no venting or gas line, but they draw a lot of power, so we check your electrical panel's capacity before recommending one.
Do you repair tankless water heaters?
Yes. We diagnose error codes, ignition and flame problems, clogged inlet filters, scale build-up and lukewarm water on all major brands, and descale units as part of the repair when needed.
