FAQs
How long does tankless water heater repair usually take?
Most tankless water heater repairs take 1–2 hours depending on the issue. Complex problems like venting faults, gas line issues, or internal component failures may take longer.
Why is my tankless water heater not producing hot water?
Common causes include mineral buildup, ignition failure, gas supply issues, blocked venting, or a faulty flow sensor. A technician can diagnose the exact cause and restore hot water.
Why does my tankless water heater shut off during use?
Short cycling or sudden shutdowns can happen when the unit is undersized, clogged with scale, incorrectly vented, or experiencing gas pressure problems. Repairs or maintenance can resolve these issues.
Why is my tankless water heater displaying an error code?
Tankless units display error codes for problems like overheating, airflow restrictions, ignition failure, low water pressure, or scale buildup. A technician can interpret and fix the specific code.
Can a tankless water heater be repaired instead of replaced?
Yes. Many tankless issues are repairable, including ignition problems, clogged filters, sensor failures, and mineral buildup. Replacement is usually only necessary for major component failure or very old units.
Does hard water affect tankless water heaters?
Yes. Hard water causes scale buildup inside tankless units, which can reduce performance and trigger error codes. Regular descaling and maintenance help prevent these issues.
Do you repair all brands of tankless water heaters?
Yes. Licensed HVAC technicians can repair most major tankless water heater brands and models, including gas, propane, and high-efficiency units.
