Why is my water not getting hot enough?
Sediment buildup, a failing element (electric), a weak gas valve/igniter (gas), or a mixing valve issue can reduce temperature. We test components and flush if needed.
Why is my tank making popping or banging noises?
That’s usually sediment boiling at the bottom of the tank. A flush and anode-rod check typically solve it and improve efficiency.
My tankless shuts off mid-shower—why?
Scale, clogged inlet screens, undersized gas lines, or faulty sensors/PCB can cause shutdowns. We descale and verify gas/airflow and controls.
There’s water around the tank—do I need a new one?
Not always. It could be fittings, T&P discharge, condensate, or the tank itself. We locate the leak and advise on repair vs. replacement.
How long does a typical repair take?
Many are same-day. Special-order parts or significant leaks may require a return visit.
Will repairs affect my warranty?
We follow manufacturer procedures and use OEM-grade parts to help preserve eligible warranties.
