Tankless repair FAQ

Questions, answered

Why is my tankless showing an error code? +
Error codes point to a specific fault, such as ignition failure, a flow or temperature sensor, venting, or scale buildup. We read the code, diagnose the real cause and repair it.
Why is there no hot water? +
No hot water from a tankless unit is often an ignition fault, a gas or venting issue, a failed sensor, or heavy scale. We diagnose the exact cause and repair it.
What is descaling and do I need it? +
Descaling flushes mineral buildup out of the heat exchanger. In hard-water areas it is essential, usually once a year, to keep your tankless heating fully and avoid errors.
How much does tankless repair cost? +
Repair cost depends on the fault and parts. Descaling is a flat rate. Either way you get a clear price upfront and approve it before we start.
Why is my hot water flow low? +
Low flow is often caused by scale in the heat exchanger, a clogged inlet filter, or a partially closed valve. We find the cause and restore full flow.
Can you repair it the same day? +
Yes — we carry common tankless parts and offer same-day repair across Orlando, Kissimmee and St. Cloud. Call us and we will head your way.
