Tankless Units in Arlington Homes
In Arlington, units are often in a basement or crawl-space-level utility room. Freeze protection and a clear condensate line keep them running through winter.
What we run into in Arlington
- 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.

Call (380) 273-8196Tankless Problems We Fix Around Arlington
The list below covers what we find on most visits for tankless water heater repair in Arlington, VA, from ignition codes to drips under the cabinet.
Unit won't light
No ignition usually means gas pressure, a worn igniter, a dirty flame rod or a blocked vent. Each is tested.
Water under the unit
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.
Noisy or whistling
Scale, a struggling fan or a gas regulator issue, each of which shows up on testing.
Error code keeps coming back
A reset only clears the symptom. Repeated ignition or exhaust codes need a visit.
Shuts off mid-shower
Flow drops below what the unit needs to keep firing: a clogged filter, aerator or shower cartridge, or a sensor misreading.

Fix It or Retire It? Deciding in Arlington
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.

Arlington Homes by the Numbers
Gas heats about 47% of homes in Arlington and electricity about 51%, so both gas and electric tankless units turn up on calls here. With a median build year of 1976, many homes in Arlington were set up for a tank heater, which means a tankless unit often depends on a retrofitted gas line, vent run or drain. Only about 42% of homes are owner-occupied, so many calls come from landlords and property managers, who usually want the cause and the price in writing.
With about 235,463 residents on roughly 26 square miles (near 9,056 per square mile), Arlington is dense, with many repairs happening in shared buildings, basements and utility closets. Among the 85 Virginia places we cover, it ranks number 3 by population.

Call (380) 273-8196How much does tankless water heater repair in Arlington, VA 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.
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.
Why does my tankless water heater go hot then cold?
A brief cold slug after a tap reopens is the unit restarting. Swings during one shower usually mean flow below the unit's minimum, scale on the exchanger, or a failing flow sensor.
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.
