Tankless Units in Arlington Heights Homes
In Arlington Heights, basement units with PVC sidewall vents are typical. Scale from the hard water and snow at the termination are the faults we see most.
What we run into in Arlington Heights
- 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.

Call (380) 273-8196How much does tankless water heater repair in Arlington Heights, 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.
What is the most common problem with tankless water heaters?
Scale in the heat exchanger, followed by ignition faults and flow sensor or filter problems. All three usually show up as a code or as water that won't stay hot.
Is there a reset button on a tankless water heater?
Many do it through power: switch the unit off, wait, switch it back on. That clears a code, but a code that comes back means a part needs attention.
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.
