Call (380) 273-8196What We Repair on Tankless Units in Antelope

Error codes & ignition
Units that click but never light, or light and drop out, get the ignition and gas side tested and repaired.

Descaling & flushing
Scale dissolved out of the heat exchanger through the service valves, with valves added if the unit has none.

Flow sensors, filters & leaks
Temperature swings, low flow and drips under the cabinet traced to the sensor, filter or a failing seal.

How a Repair Visit Runs in Antelope
A tankless unit can fail for a dozen reasons that look the same at the tap. This sequence narrows them down.
- 01
Error history read
The code on the display and the unit's stored fault history are read before a single cover comes off.
- 02
Gas pressure under load
- 03
Flow and inlet filter
The inlet filter screen is cleaned and the flow rate checked. Too little flow and a unit will not fire at all.
- 04
Ignition and flame
- 05
Venting and condensate
- 06
Sensors and board
The flow sensor, thermistors and control board are tested against the maker's published values.
- 07
Fixed, then run hard
Tankless Problems We Fix Around Antelope
When people phone about tankless water heater repair in Antelope, CA, it is nearly always one of these problems. Each has a short list of causes.

Code 11, E003 or 111
A unit that clicks without lighting has an ignition, gas or venting fault, and each is checked in turn.

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

Venting fault
Venting codes mean the unit can't breathe: a blocked termination, a nest, snow or a vent run that's too long.
Noisy or whistling
Scale, a struggling fan or a gas regulator issue, each of which shows up on testing.
Error code keeps coming back
A reset only clears the symptom. Repeated ignition or exhaust codes need a visit.
Shuts off mid-shower
Flow drops below what the unit needs to keep firing: a clogged filter, aerator or shower cartridge, or a sensor misreading.
Can't tell which one you have? Read us the display and describe the water, and the likely fault comes back on the call.

The code is a starting point
Error codes name a system, not a part. Gas, flow, venting and sensors are measured before anything is replaced.
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.
Quote in writing
The cause and the price are written down before work starts, whether the job is a filter or an exchanger.

Call (380) 273-8196How much does tankless water heater repair in Antelope, CA 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. Whatever the fix, the price is agreed in writing before work begins.
How often should a tankless water heater be flushed?
Once a year for most homes, and twice a year on very hard water. Soft-water homes can stretch it, but never skip it for years.
Is there a reset button on a tankless water heater?
Most units reset by switching power off and on, or through the controller. A reset clears the code, not the cause; ignition and exhaust codes that return need a repair visit.
How long does a tankless water heater last?
Gas units commonly run 20 years or more when they are flushed on schedule. Electric tankless units tend to last closer to 7 to 10 years.
