How a Repair Visit Runs in Key West

These are the checks behind a repair visit. Each one rules a cause in or out before money is spent on parts.

  1. 01

    Gas pressure under load

  3. 03

    Flow and inlet filter

    Venting and condensate

    Intake and exhaust terminations are checked for blockage, and the condensate line for clogs and corrosion.

Why Key West Homeowners Call Us

Scale treated, not ignored

If scale caused the fault, the exchanger is descaled as well, so the same code doesn't return next month.

The cause and the price are written down before work starts, whether the job is a filter or an exchanger.

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.

How much does tankless water heater repair in Key West, 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. Whatever the fix, the price is agreed in writing before work begins.

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.

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 is my tankless water heater not turning on?

First confirm power and gas. If both are there, the usual causes are low flow, a dirty inlet filter, a bad flow sensor or an ignition fault.
