Tankless Water Heater Repair in Fort Myers

45+ Years Diagnosing On-Demand Systems in Lee, Collier & Charlotte Counties

When your tankless water heater stops delivering hot water or flashes an error code, you need a plumber who knows on-demand systems, not someone who primarily services storage tanks and is guessing at unfamiliar components. Southern Plumbing Solutions has been repairing plumbing systems across Fort Myers and Southwest Florida since 1980. Our licensed, insured team works on both gas and electric tankless units every day, and pricing is disclosed before any work begins. No surprises.

Call us any time at (239) 206-4429 to schedule tankless water heater repair in Fort Myers or request a free estimate. We answer 24/7.

What Our Tankless Water Heater Repair Service Covers

Tankless systems fail differently than tank-style heaters. The components that matter are heat exchangers, flow sensors, ignition systems, burners, thermostats, and electronic control boards. Each has distinct failure signatures, and we inspect and test all of them.

Our technicians perform heat exchanger descaling when mineral scale buildup is found. On gas-fired units, we also check gas supply pressure and venting. On electric models, we evaluate electrical capacity and connections. Once we’ve identified the problem, we explain our findings in plain language and walk you through your options before any repair begins.

Common issues we diagnose and repair include:

  • Flow sensor failure causing inconsistent or absent hot water output
  • Ignition and burner malfunctions on gas tankless units
  • Error code faults triggered by scale buildup or component failure
  • Fluctuating output temperatures indicating sensor or scaling problems
  • Electronic control board failures requiring component-level diagnosis
  • Heat exchanger corrosion or scale accumulation reducing system efficiency

Repair or Replace? Honest Guidance for Fort Myers Homeowners

Not every failing tankless unit needs to be replaced, and not every repair is worth the cost. Tankless water heaters can last 15 to 20 years with proper maintenance, so a unit with an isolated component failure and meaningful service life remaining is often a solid repair candidate. Repeated error codes, heat exchanger corrosion, or a cracked unit body typically point toward replacement as the more practical path.

We don’t push a single outcome. Our goal is the most cost-effective solution for your situation. If you’re also considering a switch from a tank system to tankless, we handle the full plumbing scope, including any gas line or electrical capacity upgrades the conversion requires. Free estimates are available for both repair and replacement.
