Signs Your Tankless Water Heater System Needs Repairs
- Low Hot Water Pressure or Reduced Flow
- Loud Clicking, Humming, or Grinding Noises
- Visible Water Leaks From the Unit or Fittings
- Cloudy, Discolored, or Grungy Hot Water
Lukewarm water, temperature swings, a long wait for hot water, or an error code on the display all point to a problem. Mineral scale building up in the heat exchanger is one of the most common causes, and a descaling flush often fixes it. Having an expert look at it early keeps a small problem from turning into a bigger one.

Our Tankless Water Heater Diagnostic and Repair Process
We start with the error code history, then check gas pressure, venting, water flow and the heat exchanger. We explain what failed and give you the price before any work starts. If scale is the problem, we descale the unit and clean the inlet filter. If repair costs are a concern, ask about financing. Regular water heater maintenance, including descaling, helps keep scale from coming back.

Frequently Asked Questions
Temperature swings, error codes, reduced flow, leaks, or a unit that shuts down on its own are the key signs. Getting it looked at early can prevent more serious damage.
Write down the code and call us. Many codes point to scale buildup, a venting or gas supply problem, or a flow sensor, and the code helps our technician find the problem. Avoid opening the unit yourself.
A service call is $110, or $175 after hours, and covers the trip to your home. Diagnostic work and any repairs are added on top, and you approve the price before we start. Members of our ESA maintenance plan pay $0 for service calls. Tankless parts can cost more than tank parts, so we always give you the price before we start.
Tankless water heaters often last 20 years or more with regular maintenance, so repair usually makes sense unless the heat exchanger has failed or repairs keep adding up. We'll give you honest advice and both options.
Yes. Emergency service is available any day and any time for urgent tankless water heater repairs, subject to on-call technician availability. We understand losing hot water is a major inconvenience.
Most manufacturers recommend descaling at least once a year, and more often with hard water. It keeps the heat exchanger clean and the unit running efficiently. See water heater maintenance.
