Tankless Units in South Lyon Homes
South Lyon winters are cold enough to freeze an exposed line, and the groundwater is mineral-heavy. Descaling and freeze repairs are both regular work here.
What we run into in South Lyon
- 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.
- Hard water. Mineral-heavy water coats the exchanger a little more every month. Many repair visits here end with a descale as well, so the fix holds.

Call (380) 273-8196Tankless Problems We Fix Around South Lyon
These are the faults behind most calls for tankless water heater repair in South Lyon, MI. The display usually points at one of them.
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.
Frozen after a cold night
Lines feeding the unit froze, or freeze protection lost power.
Noisy or whistling
Scale, a struggling fan or a gas regulator issue, each of which shows up on testing.
Hot, then cold, then hot
A short cold burst after the tap reopens is normal start-up. Swings during one shower point to low flow, scale or a failing flow sensor.

Fix It or Retire It? Deciding in South Lyon
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.

Call (380) 273-8196How much does tankless water heater repair in South Lyon, MI 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 buildup tops the list, then ignition trouble, then flow sensors and clogged inlet filters.
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.
Can a tankless water heater be repaired?
Usually, yes. Nearly every part on a tankless unit can be replaced, and a scaled exchanger can be cleaned. The exception is an old unit whose heat exchanger has started to leak.
