Most Fort Mohave homes hang the tankless on an outside stucco wall. The water is very hard, so descaling is often part of the repair.

What we run into in Fort Mohave

  • Hard water. The water here carries a lot of minerals, and they settle as scale inside the heat exchanger. LC codes, overheat faults and water that will not get hot often trace back to it.
  • Outdoor wall units. Exterior wall units are common in this area. Sun-cracked pipe insulation and wasp nests in the vent cap turn up on service calls.

An air or exhaust code stops the burner for safety. The intake and exhaust are cleared and checked.

Noisy or whistling

Scale, a struggling fan or a gas regulator issue, each of which shows up on testing.

Fix It or Retire It? Deciding in Fort Mohave

Most tankless faults are repairs, plain and simple. Replacement only makes sense when the heat exchanger has failed out of warranty or an electric unit is near the end of its shorter working life.

Read the model and serial off the label and call (380) 273-8196. The age and the fault together usually settle repair versus replace on the phone.

Local climate

Fort Mohave Weather and Water Temperature

624 ftabove sea level
75°Fyearly average air
10 nightsat or below freezing
~64°Fwinter tap water

Hard freezes are rare in Fort Mohave, roughly 10 nights a year, but the coldest night of the past three years still dipped to about 31°F. One cold snap can catch outdoor units and uninsulated lines that were never built for it.

In Fort Mohave the cold tap is probably around 64°F in winter and 85°F in summer, based on a January average of 53°F, a July average of 99°F and a yearly average of 75°F. Heating that water to 120°F takes a rise of about 56°F in winter, so a 199,000 BTU gas unit at 90% efficiency tops out near 6.4 gallons per minute, compared with roughly 10.2 in summer when the rise is only about 35°F.

Since a shower uses about 2 gallons per minute, that winter ceiling is why a heater that handles one shower easily can run lukewarm when a second shower and the dishwasher start. Lukewarm water at full demand is a limit of the design, not always a fault, whereas lukewarm water at a single tap points to scale, a sensor or an ignition problem.

Fort Mohave sits near 624 ft, well under the 2,000 ft level at which gas appliances commonly need altitude adjustments, so burner output should not be a concern from elevation alone.

How much does tankless water heater repair in Fort Mohave, AZ cost?

Most repairs cost an estimated $150 to $800, depending on the part. Descaling alone is estimated at $150 to $350, and a heat exchanger at $1,000 to $2,500. On hard water, a descale often goes with the repair and sits on the same written quote.

How long does a tankless water heater last?

A gas unit that is flushed regularly commonly lasts 20 years or longer. Electric tankless models usually give 7 to 10. In Fort Mohave the heat exchanger works through a rise of about 56°F on a typical winter day, which is why flushing on schedule matters there.

Can a tankless water heater be repaired?

Yes, in most cases. Igniters, flame rods, flow sensors, thermistors, fans, gas valves and boards are all replaceable, and scale can be descaled. A leaking heat exchanger on an old unit is the main exception.

Is there a reset button on a tankless water heater?

Many do it through power: switch the unit off, wait, switch it back on. That clears a code, but a code that comes back means a part needs attention.
