If your tankless unit will not fire, the cause may be a dirty flame rod, a bad igniter, low gas pressure or a blocked intake. We test each component and measure gas pressure at the inlet.

Tankless Repair vs Replacement Cost in Anaheim, CA
Descaling service usually costs $175 to $350, and sensor or igniter repairs run $250 to $600. Heat exchanger replacement can cost $800 to $1,500 or more unless covered by warranty.

Condensing tankless heaters, such as many Navien models, extract extra heat from exhaust and produce condensate.
