Frequently Asked Questions
How often should a tankless water heater be serviced?
Annual maintenance is recommended for all tankless water heaters. In Snohomish County, where water hardness can cause mineral buildup, annual descaling is especially important to maintain efficiency and prevent premature failure.
What does tankless water heater maintenance include?
Our service includes descaling (flushing the heat exchanger with a descaling solution), cleaning the inlet filter screen, inspecting the burner assembly (gas units), checking the venting, and testing all safety controls. You receive a written report of findings.
Why is my tankless water heater showing an error code?
Error codes vary by brand. Common codes indicate ignition failure, overheating, flow sensor issues, or venting problems. Call us at 425-610-6635 and we can often help diagnose the code over the phone before scheduling a visit.
Why is my tankless water heater not producing hot water?
Common causes include a tripped error code, a failed igniter (gas units), a faulty flow sensor, a clogged inlet filter, or a venting issue. Our $69 diagnostic will identify the exact cause.
How much does tankless water heater repair cost?
Our diagnostic is $69 and is applied toward the repair. Common repairs — flow sensors, igniters, control boards, descaling — typically range from $150–$600. We provide a written quote before any work begins.
Can you service any brand of tankless water heater?
Yes — we service all major brands including Rheem, Navien, Rinnai, Noritz, Bosch, and more. Call us to confirm availability for your specific model.
What happens if I don't descale my tankless water heater?
Mineral scale buildup on the heat exchanger reduces efficiency, causes overheating, and can lead to premature failure. Annual descaling is the single most important maintenance task for a tankless water heater in our area.
