Tankless Units in Longview Homes
Most Longview homes are brick houses where the tankless sits in the garage or on an outside wall. The February 2021 freeze showed how fast exposed lines can split here.
What we run into in Longview
- Freeze damage. Freeze protection keeps the inside of a unit safe, not the exposed pipes under it. Uninsulated lines are where winter damage usually starts.
- Retrofit installs. Plenty of units here were fitted into older homes after the fact, and an undersized gas line or a long vent run can cause ignition faults years later.

The list below covers what we find on most visits for tankless water heater repair in Longview, TX, 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.
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.

Heating in Longview splits between gas (about 38% of homes) and electricity (about 61%), and tankless repairs follow the same split. With a median build year of 1978, many homes in Longview were set up for a tank heater, which means a tankless unit often depends on a retrofitted gas line, vent run or drain. Roughly 53% of homes are owner-occupied and 64% single-family, so calls come from both homeowners and landlords.

Call (380) 273-8196How much does tankless water heater repair in Longview, TX 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.
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.
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.
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.
