Tankless Water Heater Repair & Maintenance 

Start with the basics: confirm the thermostat setting, check that the breaker has not tripped, and look for obvious leaks or pooling water. If that does not restore hot water, call us for a full diagnostic; we offer 24/7 service across Durham, Raleigh, and the greater Triangle.

It depends on the issue, the parts involved, and labor. Simpler fixes such as a thermostat replacement or a descaling run less than major work like a heat exchanger or gas control valve replacement. We give you a clear, upfront estimate after an in-person diagnostic.

Watch for water that takes longer than usual to heat, hot water that runs out faster than it used to, strange odors, rumbling or banging noises, or leaking around the unit and its connections. Any of these is a good reason to schedule service before the issue gets worse.

If the unit is past the 12-year mark, needs frequent repairs, or no longer heats efficiently, replacement is often the more cost-effective choice over time. For newer units or a single minor issue, repair usually makes more sense. We walk you through the trade-offs for your specific system rather than defaulting to one answer.

We repair electric tankless units, gas tankless units, and point-of-use models installed at a single fixture. We also perform the flushing and descaling that prevents the mineral buildup behind many of these failures in the first place.
