Ignition Failure Repair in Santa Rosa, CA
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. Undersized gas lines are a frequent hidden cause when a tankless unit replaced a tank. We correct the issue so the unit lights reliably.

Recirculation Pump Repair in Santa Rosa
Many tankless systems use internal or external recirculation to deliver hot water more quickly. Pump failures, check valve problems or wrong schedule settings can cause long waits or lukewarm water.

We prioritize fast, efficient service to minimize disruption to your business operations.
