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.

Frequently Asked Questions About Tankless Water Heater Repair in Santa Cruz
The cost of tankless water heater repair in Santa Cruz varies a lot depending on the issue, ranging from $150 for minor fixes like sensor replacement to $600 or more for complex repairs involving heat exchanger descaling or major component replacements. We provide a detailed estimate after identifying the specific problem.
Codes point to specific faults such as ignition failure, flame loss, overheating or scale buildup. Each brand uses its own code list, and we use manufacturer guides to interpret them.
While some basic maintenance like filter cleaning can be done by homeowners, complex repairs involving gas lines, high voltage electricity or intricate internal components should always be left to a licensed professional. DIY attempts can be dangerous and void warranties.
We stand behind our tankless water heater repairs with a solid warranty on both parts and labor. The exact warranty period will be discussed with you before any work begins, providing you peace of mind.
Minor tankless water heater repairs, such as replacing a sensor or igniter, usually do not require a permit in Santa Cruz. Major component replacements, changes to the gas or water lines, or replacing the entire unit may require a plumbing permit to ensure code compliance.
Fluctuating temperatures can come from low flow rates, a dirty inlet filter, a failing flow sensor or scale on the heat exchanger. Crossed hot and cold lines at a fixture can also be the cause.
Regular professional maintenance, including descaling and checking all connections, is the best prevention. Installing a whole-home water softener can also greatly reduce mineral buildup in areas with very hard water.
In homes with hard water and no softener, once a year is a good rule. Homes with a softener may go longer, but annual inspection is still smart.
