Tankless Units in Leesburg Homes
Across Leesburg, scale from the hard water is the most common reason a unit loses heat. A descale and a clean filter fix a surprising number of calls.
What we run into in Leesburg
- 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.
- Garage installs. Garage installs are the norm in this area, usually with the vent running straight out the nearest wall.

Error codes & ignition
Code 11, E003, 111 and their cousins traced to the gas supply, igniter, flame rod or venting, then fixed.

Descaling & flushing
A pump circulates descaler through the exchanger until the scale is gone, then the filter is cleaned too.

Flow sensors, filters & leaks
Units that shut off mid-shower or drip from below get the flow sensor, filter, valves and fittings sorted.

Tankless Problems We Fix Around Leesburg
Most requests for tankless water heater repair in Leesburg, FL start with one of the symptoms below, and most end with a single part or a descale.

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.
Error code keeps coming back
A reset only clears the symptom. Repeated ignition or exhaust codes need a visit.
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.
Not as hot as it used to be
Scale on the heat exchanger, a weak gas supply or a thermistor reading wrong.
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 Leesburg
Igniters, flame rods, sensors, fans, gas valves and boards are worth replacing on almost any unit. The hard call is a leaking or cracked heat exchanger on an older unit, because that part can approach the price of new.
Tell us the brand, roughly how old the unit is and what it is doing when you call (380) 273-8196. If a repair is a poor spend, you will be told so.

Why Leesburg Homeowners Call Us
Run hard before we go
The unit is pushed with several taps open and its outlet temperature watched before the visit ends.
The code is a starting point
Error codes name a system, not a part. Gas, flow, venting and sensors are measured before anything is replaced.
Scale treated, not ignored
If scale caused the fault, the exchanger is descaled as well, so the same code doesn't return next month.

Call (380) 273-8196How much does tankless water heater repair in Leesburg, FL 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.
How often should a tankless water heater be flushed?
Once a year for most homes, and twice a year on very hard water. Soft-water homes can stretch it, but never skip it for years.
Is there a reset button on a tankless water heater?
Most units reset by switching power off and on, or through the controller. A reset clears the code, not the cause; ignition and exhaust codes that return need a repair visit.
How long does a tankless water heater last?
Gas units commonly run 20 years or more when they are flushed on schedule. Electric tankless units tend to last closer to 7 to 10 years.
