Tankless Units in Jeffersonville Homes
Most Jeffersonville homes keep the tankless in the basement, beside the furnace. Hard water and cold winters are what wear these units down.
What we run into in Jeffersonville
- Basement units. Many units here sit in the basement with PVC pipes venting out through the rim joist, and the condensate has to drain somewhere sensible.
- 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.
- Hard water. With water this hard, a unit that has never been flushed is usually running hot inside and cold at the tap. Descaling is often half of the cure.

Call (380) 273-8196Tankless Problems We Fix Around Jeffersonville
The list below covers what we find on most visits for tankless water heater repair in Jeffersonville, IN, from ignition codes to drips under the cabinet.

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.
LC code on a Rinnai
The unit is reporting scale buildup. It needs a descale, and soon.
Display is blank
No power at the outlet, a blown fuse or a failed control board.
Noisy or whistling
Scale, a struggling fan or a gas regulator issue, each of which shows up on testing.

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.
