Tankless Units in McLean Homes
Most McLean homes keep the tankless in the basement or a utility room, with the vent through the side wall. Winter cold snaps and condensate drains cause the usual trouble.
What we run into in McLean
- Basement units. Basement installs are common, often condensing units whose acidic condensate runs to a floor drain or a small pump.
- 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.

When people phone about tankless water heater repair in McLean, VA, it is nearly always one of these problems. Each has a short list of causes.
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
Water below a tankless can be a valve, a fitting, condensate or a failed exchanger. The source decides the cost.
Venting fault
An air or exhaust code stops the burner for safety. The intake and exhaust are cleared and checked.
Not as hot as it used to be
Scale on the heat exchanger, a weak gas supply or a thermistor reading wrong.
Cold at one tap only
Usually a mixing valve or a cold-water crossover at that fixture, not the heater.
Display is blank
No power at the outlet, a blown fuse or a failed control board.
Can't tell which one you have? Read us the display and describe the water, and the likely fault comes back on the call.
Fix It or Retire It? Deciding in McLean
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.

McLean Homes by the Numbers
Gas heats about 72% of homes in McLean, so gas tankless units, with their vent runs and gas-line sizing, are the usual case on a call. Housing here is older (median year built 1976), and older homes were plumbed and vented for tank heaters, so tankless retrofits often meant new gas lines, venting or a condensate drain, which are common places for faults to start. About 86% of homes are owner-occupied and about 91% are single-family, so most repair decisions here are the homeowner's own.
McLean covers about 25 square miles and holds roughly 50,232 residents, around 2,025 per square mile: spread out, with mostly detached homes on larger lots and longer runs between fixtures and the street. It is number 10 by population of the 85 Virginia places on our service list.
