DOES THIS SOUND FAMILIAR?
Signs your tankless unit needs repair
Lukewarm water
Commonly scale buildup in the heat exchanger, especially on hard well water.
Hot water that cuts in and out
Flow sensor problems, or a unit too small for several fixtures at once.
Unusual noises or a burning smell
Shut it off and call.
Safety first
If you smell gas near a gas tankless unit, leave the house and call your gas utility or 911 from outside.
WHAT WE USUALLY FIND
Common causes we find
Scale and mineral buildup, the most common cause on Southern Ohio well water.
Ignition and flame sensor failures on gas and propane units.
Venting and air intake problems that trigger safety shutdowns.
Flow sensor and inlet filter issues that keep the unit from firing.
Undersized units that can't keep up with household demand.
Diagnosis first
We read the fault code, test the ignition, sensors, gas supply and venting, and check for scale, then explain what failed and what it costs.
WEIGHING YOUR OPTIONS
Repair or replace?
Tankless units often last 15 years or more with regular descaling, so most problems are worth repairing. If an older unit needs a heat exchanger or keeps failing, replacement may be the better value. See tankless water heater replacement.
CLEAR SCOPE. INFORMED DECISIONS.
What affects the cost
Cost depends on the part, the unit's age and whether descaling or venting work is needed. We quote before we start. Financing is available for all credit types, including 0% APR for 72 months, with approved credit.
