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

Usually a mixing valve or a cold-water crossover at that fixture, not the heater.

Mount Pleasant Homes by the Numbers
With electricity the main heating fuel in Mount Pleasant (about 92% of homes), many tankless units here are electric, and their faults are elements, breakers and sensors rather than burners. With a median build year of 1984, homes in Mount Pleasant sit in the middle: plenty were retrofitted with tankless units, and plenty of those units are now old enough to need parts. About 78% of homes are owner-occupied and about 74% are single-family, so most repair decisions here are the homeowner's own.

Mount Pleasant Weather and Water Temperature
Freezing nights are not constant in Mount Pleasant, about 55 a year, but the coldest one in the last three years reached about 10°F. A unit mounted outdoors or in an unheated garage is exposed on those nights, and a leak found in spring often started in January.
Water arriving at a Mount Pleasant tap in winter is likely near 51°F (averages of about 41°F in January air and 61°F over the year). To reach 120°F a tankless unit must add roughly 69°F, which a 199,000 BTU gas model at 90% efficiency can do for about 5.2 gallons per minute. In July the water is nearer 71°F, so the same unit has to add only about 49°F and can supply about 7.3 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.
Mount Pleasant sits near 595 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.

Call (380) 273-8196How much does tankless water heater repair in Mount Pleasant, 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.
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 Mount Pleasant, cold nights add vent-cap, condensate-line and exposed-pipe problems to the usual list.
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. In Mount Pleasant freezing nights are few (about 55 a year), so any season works; choose a month when the household can go without hot water for an hour.
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 Mount Pleasant, after a hard freeze also check whether the condensate line has frozen, since many condensing models shut down when it blocks.
