Tankless Units in Lombard Homes
Most Lombard homes keep the tankless in the basement near the floor drain. Harsh winters, snow at the vent and hard water all leave their mark.
What we run into in Lombard
- Basement units. Basement installs are common, often condensing units whose acidic condensate runs to a floor drain or a small pump.
- Snow on vents. Snow drifting against a sidewall vent will stop a unit cold with a venting code until the termination is cleared.
- 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.

These are the faults behind most calls for tankless water heater repair in Lombard, IL. The display usually points at one of them.
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
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.
Display is blank
No power at the outlet, a blown fuse or a failed control board.
Frozen after a cold night
Lines feeding the unit froze, or freeze protection lost power.
Error code keeps coming back
A reset only clears the symptom. Repeated ignition or exhaust codes need a visit.

Lombard Homes by the Numbers
Gas heats about 84% of homes in Lombard, 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 1971), 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. Owners live in about 70% of Lombard homes (single-family about 61%), so the person who calls is usually the person who decides.
With about 43,722 residents on roughly 10 square miles (near 4,299 per square mile), Lombard is suburban in density, with a mix of detached homes and townhomes. It is number 30 by population of the 225 Illinois places on our service list.

Call (380) 273-8196How much does tankless water heater repair in Lombard, IL 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. On hard water, a descale often goes with the repair and sits on the same written quote.
Why is my tankless water heater not turning on?
Check for power at the outlet and that the gas valve is open. Beyond that it is usually low flow, a clogged inlet filter, a failed flow sensor or an ignition fault.

A gas unit that is flushed regularly commonly lasts 20 years or longer. Electric tankless models usually give 7 to 10.
Can a tankless water heater be repaired?
Yes, in most cases. Igniters, flame rods, flow sensors, thermistors, fans, gas valves and boards are all replaceable, and scale can be descaled. A leaking heat exchanger on an old unit is the main exception.
