Tankless water heaters are efficient and reliable—but like any system, they can develop issues over time. Here's what we repair:
No Hot Water or Inconsistent Temperature
If your water runs cold or fluctuates between hot and cold, the issue could be a faulty heating exchanger, sensor, or gas valve. We'll diagnose the root cause and get your system heating properly again.
Error Codes on Display
Modern tankless units display error codes when something's wrong. We know what those codes mean and can quickly address problems like flame failure, ignition issues, or a blocked vent.
Low Water Pressure or Flow Issues
Mineral buildup inside the heat exchanger can restrict water flow and reduce pressure. We flush and descale your system to restore full performance.
Strange Noises or Vibrations
Rumbling, rattling, or humming sounds often signal sediment buildup, a failing fan, or loose components. We'll track down the source and fix it.
Leaks Around the Unit
Water pooling near your tankless heater can indicate a cracked heat exchanger, loose fittings, or valve issues. We'll locate the leak and make the necessary repairs to protect your home.
System Won't Turn On
If your unit won't fire up, the problem could be electrical, a gas supply issue, or a failed igniter. We troubleshoot the entire system to get it running again.
Tankless water heaters are our specialty—it's right in our name. We've installed, maintained, and repaired many tankless systems across the Concord area, so we know these units inside and out.

We'll never push an unnecessary replacement. If your unit can be repaired affordably, we'll fix it. If it's time for a new system, we'll explain why and give you options that fit your needs and budget.
