Water Heater Service in Greater Atlanta

A water heater that won’t heat after you press the reset button usually has a bad thermostat or heating element that keeps tripping the high-limit safety switch (the reset button). The next most common causes are heavy sediment causing overheating in tank models or, on gas units, an igniter or airflow issue that prevents the burner from running. Repeated trips mean the safety is doing its job and the parts need testing with a meter, not more resets. Our technicians handle these problems daily around the greater Atlanta area, Alpharetta, Marietta and Roswell and nearby, including Decatur homes. For urgent situations, we offer same-day service.

Use these quick signals to choose your next step:

• Reset pops again soon after heating starts: schedule repair.
• Electric unit has power but no heat: likely a failed element.
• Burner won’t light or you smell gas: call for emergency service.

Turn off power or gas and the cold-water supply if the reset keeps tripping or you notice burning smells or leaks.

A water heater that has power but no heat is usually caused by failed heating elements or a control/thermostat fault. On electric units, a burned-out upper element or tripped high‑limit safety is most common; on gas or hybrid units, ignition or fuel‑supply faults can stop heating even when the unit has power. Tankless systems may also refuse to heat if flow is too low or a sensor is scaled. Sediment buildup can insulate heat and trigger safety lockouts, and I often see units short-cycle after a recent power event. We service the North Druid Hills area and handle diagnostics on tank, tankless, and heat pump water heaters, with free replacement estimates when needed.

Try these safe checks before calling:

• Confirm the setpoint is 120–130°F and the unit isn’t in vacation mode.
• For gas, verify the gas valve is open and note any error code or failed ignition.
• For tankless, run a full‑flow hot tap to meet the minimum flow rate.
• Look and listen for rumbling or leaks that suggest heavy sediment. The safest next step is to stop using the unit if it trips repeatedly or leaks and schedule a licensed technician. <br/>
