What A Tankless Water Heater Repair Visit Includes

  • We test before we quote. Error codes, the igniter, the flow sensor, the gas supply, the venting and scale in the heat exchanger, so the diagnosis is a diagnosis and not a guess.
  • You hear the fault in plain language. The part named, the price given, and the choice left with you.
  • We leave it working. Hot water run at the taps, and the venting and relief valve checked, before we pack up.
  • If it is near the end, we say so. And we tell you what a replacement would actually involve, without turning it into a sales call.

When To Call For Tankless Water Heater Repair In Novi

Water heater calls are mostly these six.

  1. Hot water runs cold mid shower

    Scale in the heat exchanger, a flow sensor, or a unit too small for the demand.

  2. An error code on the display

    The unit telling you what it has found. We read it and test from there.

  3. No hot water at all

    Ignition, the gas supply, the venting or a power fault.

  4. Hot water takes ages to arrive

    Distance from the unit, or a flow rate too low to fire it.

  5. A clicking or banging noise

    Ignition trouble or scale.

  6. It has not been descaled in years

    Scale costs output first, then parts.

I noticed that my furnace was not working around 3pm.  I called and a service person was there a little after 4 and took less than an hour to fix it.  I am very happy with the service.

Questions We Get Asked About Tankless Water Heater Repair In Novi

Do You Do Emergency Tankless Water Heater Repair In Novi After Hours?

Yes. The phone is answered any hour of the day or night. After hours it goes to our own after hours team, who take the details and get a technician moving rather than leaving you a message to call back in the morning.

Is There A Dispatch Fee For Tankless Water Heater Repair In Novi?

No. There is no dispatch fee in the Detroit and Novi area for repair or maintenance visits. The work is priced before we start, and you can say no.

Why Does My Tankless Water Heater Go Cold In The Shower?

Most often scale in the heat exchanger, a flow sensor, or more hot water running at once than the unit is sized for. A descale fixes the first.

How Often Should A Tankless Water Heater Be Descaled?

Once a year for most houses, more often with hard water. It keeps the output up and the warranty valid.
