    Chose First Call for the installation of a new furnace and AC a few years ago. From the quote to the installation to the service, everyone from First Call has been thorough and thoughtful from start to finish. Can’t recommend them enough and I hope they will decide to do service and warranty work on Devon soon so that I can continue working with them in my new home.

    I am pleased with the estimator, Chris.  He was punctual, informative and knowledgeable of his craft.  He was forthcoming and honest, didn’t candy coat the quote.  As this was just a quote and no service or payment was issued, I chose the least price range.

    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?
