These are the faults behind most calls for tankless water heater repair in Ducor, CA. The display usually points at one of them.
Unit won't light
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
An air or exhaust code stops the burner for safety. The intake and exhaust are cleared and checked.
Cold at one tap only
Usually a mixing valve or a cold-water crossover at that fixture, not the heater.
LC code on a Rinnai
The unit is reporting scale buildup. It needs a descale, and soon.
Frozen after a cold night
Lines feeding the unit froze, or freeze protection lost power.

Fix It or Retire It? Deciding in Ducor
Gas tankless units commonly last 20 years or more with flushing, so a single failed part rarely means a new heater. A failed exchanger outside its warranty, on a unit past 15 years, is where replacement starts to win.

Ducor Homes by the Numbers
Heating in Ducor splits between gas (about 42% of homes) and electricity (about 52%), and tankless repairs follow the same split. Housing here is older (median year built 1970), and older homes were plumbed and vented for tank heaters, so tankless retrofits often meant new gas lines, venting or a condensate drain, which are common places for faults to start. Roughly 63% of homes are owner-occupied and 88% single-family, so calls come from both homeowners and landlords.
With about 707 residents on roughly 0.6 square miles (near 1,262 per square mile), Ducor is spread out, with mostly detached homes on larger lots and longer runs between fixtures and the street. It is number 549 by population of the 619 California places on our service list.

Ducor Weather and Water Temperature
Ducor averages around 40 freezing nights a year, with a three-year low of about 32°F. That is enough cold for pipes in garages, crawl spaces and outside walls to get close to trouble on the worst nights, while most winters pass without damage.
Water arriving at a Ducor tap in winter is likely near 62°F (averages of about 54°F in January air and 70°F over the year). To reach 120°F a tankless unit must add roughly 58°F, which a 199,000 BTU gas model at 90% efficiency can do for about 6.2 gallons per minute. In July the water is nearer 81°F, so the same unit has to add only about 39°F and can supply about 9.2 gallons per minute.
For comparison, a shower draws roughly 2 gallons per minute, so two at once plus the dishwasher can pass the winter figure. If the water goes lukewarm only when several taps run, the unit is likely maxed out; if it goes lukewarm at one tap, the cause is more often scale, a flow sensor or the flame.
At about 541 ft above sea level, Ducor is below the roughly 2,000 ft mark where manufacturers usually begin to adjust gas appliance ratings, so altitude is not a factor for most tankless units here.

Usually, yes. Nearly every part on a tankless unit can be replaced, and a scaled exchanger can be cleaned. The exception is an old unit whose heat exchanger has started to leak.
Why is my tankless water heater not turning on?
First confirm power and gas. If both are there, the usual causes are low flow, a dirty inlet filter, a bad flow sensor or an ignition fault. In Ducor, after a hard freeze also check whether the condensate line has frozen, since many condensing models shut down when it blocks.
What is the most common problem with tankless water heaters?
Scale buildup tops the list, then ignition trouble, then flow sensors and clogged inlet filters. In Ducor, cold nights add vent-cap, condensate-line and exposed-pipe problems to the usual list.
