Tankless Units in Avon Homes
Most Avon 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 Avon
- Basement units. In a basement install, a clogged condensate trap or a failed pump can shut the unit down with a code long before anyone sees water.
- Freeze damage. A hard freeze can split the pipes feeding a unit. Its built-in freeze protection only works while the unit still has power and gas.
- Hard water. The water here carries a lot of minerals, and they settle as scale inside the heat exchanger. LC codes, overheat faults and water that will not get hot often trace back to it.

The list below covers what we find on most visits for tankless water heater repair in Avon, IN, from ignition codes to drips under the cabinet.

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
Drips come from service valves, fittings, the relief valve, the condensate line or the heat exchanger itself.

Code 10 or E110
An air or exhaust code stops the burner for safety. The intake and exhaust are cleared and checked.
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 Avon
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.
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.

In Avon about 60% of homes are heated with gas, which makes gas-fired tankless units, and the gas pressure and venting problems that come with them, the common repair. With a median build year of 2003, homes in Avon sit in the middle: plenty were retrofitted with tankless units, and plenty of those units are now old enough to need parts. Owners live in about 72% of Avon homes (single-family about 82%), so the person who calls is usually the person who decides.
