Why Your Tankless Water Heater Needs Professional Attention
Unlike traditional tank-style heaters, tankless units use complex components like flow sensors, heat exchangers, ignition systems, and sophisticated electronics to heat water on demand. While highly efficient, these systems are sensitive to issues like mineral buildup, voltage fluctuations, and component wear. Attempting DIY repairs can often cause more damage or create safety hazards.
Our certified technicians have specific training in tankless water heater repair. We use advanced diagnostic tools to pinpoint the exact problem quickly and safely, ensuring the repair is done right the first time.

Common Tankless Water Heater Problems We Fix
If your tankless water heater isn't performing as it should, it might be experiencing one of these common issues. We have the expertise to address them all:
- No Hot Water or Insufficient Hot Water: This is often caused by issues like the unit being undersized for your needs, flow rate problems, or issues with the heating element or burner assembly.
- Temperature Fluctuations: Are your showers going from hot to cold unexpectedly? This can be due to cold water crossover issues, flow rate inconsistencies, or problems with the thermostat or temperature sensors.
- Leaks: Leaks can occur from loose fittings, excessive pressure, or damage to the heat exchanger. Ignoring a leak can lead to significant water damage.
- Error Codes: Tankless heaters use digital displays to show error codes when something is wrong. Our technicians can interpret these codes and understand what specific system component is failing or requires attention.
- Strange Noises: Gurgling, banging, or clicking sounds can indicate mineral buildup (scaling), or issues with internal components like the fan or pump.
- Low Water Pressure: Mineral buildup inside the heat exchanger can restrict water flow, leading to reduced hot water pressure. Clogged filters can also be a culprit.
- Ignition Failure: If the unit isn't igniting to heat the water, the problem could lie in the gas supply, the igniter component, or the flame sensor.
Symptoms Your Tankless Heater Needs Repair
Beyond a complete lack of hot water, look out for these signs:
- The unit frequently shuts off unexpectedly.
- The pilot light or igniter is not working.
- You see visible leaks around the unit or pipes.
- The water temperature isn't consistent.
- The unit displays an error code you don't recognize.
- You hear unusual sounds coming from the unit.
- Hot water pressure is lower than cold water pressure.
If you notice any of these symptoms, it's time to call a professional.

Repair vs. Replacement: Which is Right for You?

However, if your tankless water heater is older, requires frequent, expensive repairs, or the needed repair is close to the cost of a new unit, replacement might be the better long-term investment. We can help you assess the situation, considering the unit's age, the cost of the current repair, and its overall condition.
