    Tankless Water Heater Repair FAQs

    Why is my heater displaying an error code?

    Error codes indicate specific faults such as ignition failure, scale build‑up or sensor problems. We diagnose and correct the underlying issue.

    Why does the water temperature fluctuate?

    Fluctuations may be caused by sensor problems, scale build‑up or undersized units.

    Can I repair my heater myself?

    Repairs often involve gas or electrical systems and should be performed by licensed professionals.

    How quickly can you repair my unit?

    We offer same‑day service for many repairs and carry common parts on our trucks.

    Will repairs be covered by warranty?

    Manufacturer warranties may cover parts. Labour is billed separately.

    Should I repair or replace my heater?

    If your unit is approaching the end of its lifespan or has frequent issues, replacement may be more cost‑effective. We’ll provide honest recommendations.
