Tankless Units in Apex Homes

In Apex, units are often retrofits on older homes. Ignition faults and frozen lines after a cold snap are the common repairs.

What we run into in Apex

  • Freeze damage. Cold snaps do damage here when the power drops overnight. A frozen line or a cracked fitting under the unit is a repair we see after every deep freeze.
  • Retrofit installs. In older homes converted to tankless, the original gas piping is not always big enough. Pressure gets measured with the burner at full fire before parts are blamed.

How a Repair Visit Runs in Apex

A tankless unit can fail for a dozen reasons that look the same at the tap. This sequence narrows them down.

  1. 01

    Error history read

  2. 02

    Gas pressure under load

    Inlet gas pressure is measured with hot water running, because a supply that looks fine at rest can sag once the burner fires.

  3. 03

    Flow and inlet filter

  4. 04

    Ignition and flame

    Igniter, flame rod and burner are inspected and tested. A dirty rod is cleaned; a dead one is replaced.

  5. 05

    Venting and condensate

  6. 06

    Sensors and board

    The flow sensor, thermistors and control board are tested against the maker's published values.

  7. 07

    Fixed, then run hard

Common faults

Tankless Problems We Fix Around Apex

When people phone about tankless water heater repair in Apex, NC, it is nearly always one of these problems. Each has a short list of causes.

Flame rod cleaned above the burner during tankless water heater repair in Apex, NC

Code 11, E003 or 111

No ignition usually means gas pressure, a worn igniter, a dirty flame rod or a blocked vent. Each is tested.

Drip at the service valves under the unit, traced during tankless water heater repair in Apex, NC

Water under the unit

Water below a tankless can be a valve, a fitting, condensate or a failed exchanger. The source decides the cost.

Intake and exhaust terminations cleared during tankless water heater repair in Apex, NC

Venting fault

Venting codes mean the unit can't breathe: a blocked termination, a nest, snow or a vent run that's too long.

Frozen after a cold night

Lines feeding the unit froze, or freeze protection lost power.

Noisy or whistling

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

Hot, then cold, then hot

A short cold burst after the tap reopens is normal start-up. Swings during one shower point to low flow, scale or a failing flow sensor.

Fix It or Retire It? Deciding in Apex

Igniters, flame rods, sensors, fans, gas valves and boards are worth replacing on almost any unit. The hard call is a leaking or cracked heat exchanger on an older unit, because that part can approach the price of new.

Tell us the brand, roughly how old the unit is and what it is doing when you call (380) 273-8196. If a repair is a poor spend, you will be told so.

Why Apex Homeowners Call Us

Parts tested before they're bought

A flow sensor or flame rod gets checked against the maker's values, so you don't pay for a part that wasn't broken.

Scale treated, not ignored

If scale caused the fault, the exchanger is descaled as well, so the same code doesn't return next month.

Run hard before we go

The unit is pushed with several taps open and its outlet temperature watched before the visit ends.

How much does tankless water heater repair in Apex, NC 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. Freeze repairs depend on what split, and are priced once the damage is seen.

How often should a tankless water heater be flushed?

Most makers call for a flush every year, and every six months on very hard water. On very soft water the gap can be longer, but skipping it for years invites scale faults.

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.

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.
