Tankless Water Heater Repair in Sullivan's Island, SC

Is Your Tankless Water Heater Giving You Trouble? We Can Help!

Tankless water heaters, while highly efficient, can encounter a range of issues that impact their performance. Recognizing these signs early and seeking professional assistance is key to preventing further damage and restoring your comfort. Our experienced technicians are proficient in diagnosing and resolving common and complex tankless water heater problems.

No Hot Water or Intermittent Hot Water

One of the most frustrating problems is a complete lack of hot water or inconsistent heating. This often points to issues with the unit's ignition, a faulty flow sensor, or problems with the gas or water supply. For electric models, heating element failure could be the cause. Our diagnostic process includes checking gas pressure and lines, inspecting igniters and flame sensors, verifying water flow rates, and testing electrical components to pinpoint the exact reason for the hot water interruption. Once identified, we proceed with precise repairs to restore a continuous hot water flow.

Error Codes on Your Tankless Unit

Modern tankless water heaters are equipped with advanced diagnostic systems that display error codes when a problem is detected. These codes, while cryptic to the homeowner, provide valuable information to trained technicians. Common error codes might indicate issues like a clogged exhaust vent, restricted water flow, or a pressure switch malfunction. Our technicians are factory-trained to interpret these specific manufacturer error codes from leading brands. We use this information to quickly narrow down the problem, ensuring a more efficient and accurate repair process tailored to the unit's specific needs.

Fluctuating or Lukewarm Temperatures

If your hot water temperature fluctuates wildly or never quite reaches the desired heat, mineral buildup (scaling) within the heat exchanger is a common culprit. Restricted water flow due to debris, a faulty thermistor (temperature sensor), or even improper venting can also contribute to inconsistent temperatures. Our repair solutions often include professional descaling and flushing of the heat exchanger to remove mineral deposits, inspecting and cleaning filters, or replacing malfunctioning sensors. This restores the unit's ability to maintain a consistent and comfortable water temperature.

Leaks Around Your Tankless Water Heater

While less common than with traditional tank models, tankless units can still develop leaks. These leaks often originate from loose connections, worn-out gaskets, or, in more severe cases, a cracked heat exchanger. Water pooling around the unit should never be ignored, as it can lead to significant property damage. Our team employs specialized leak detection techniques to identify the precise source of the leak, whether it's a minor connection issue or a more serious internal component failure. We then perform the necessary repairs, from tightening fittings and replacing seals to more complex heat exchanger repairs or replacements.

Strange Noises (Banging, Squealing, Popping)

Unusual sounds emanating from your tankless water heater can be alarming and indicate underlying issues. A banging or knocking sound often signifies sediment buildup or mineral deposits within the heat exchanger, similar to what causes fluctuating temperatures. A squealing noise might point to a failing pump or fan motor, while a popping sound could indicate pressure issues or air trapped in the lines. Our technicians carefully listen to these sounds, using them as clues to diagnose the root cause. We then address the issue through professional flushing, component replacement, or system adjustments to ensure quiet and efficient operation.

Low Water Pressure from Tankless Heater

If the hot water flow from your fixtures seems weaker than usual, your tankless water heater could be the cause. This often stems from a clogged inlet water filter, mineral buildup restricting flow within the unit, or issues with the water supply line itself. Our service involves inspecting and cleaning or replacing clogged filters, performing a descaling flush to clear internal pathways, and checking water pressure regulators to restore optimal water flow and pressure throughout your home.

Repair vs. Replacement: Making the Right Choice

Sometimes, a repair might not be the most cost-effective or long-term solution. Our technicians provide an honest assessment to help you decide whether to repair your existing tankless water heater or consider a replacement. Factors we evaluate include:

1. Age of the Unit: Tankless water heaters typically have a lifespan of 15-20 years. If your unit is nearing the end of its expected life, frequent repairs might signal it's time for a new installation.
2. Frequency and Severity of Breakdowns: If your unit requires constant repairs or is experiencing a major component failure, replacement might offer greater long-term reliability.
3. Cost of Repair vs. New Installation: We compare the estimated repair cost against the cost of a new, more energy-efficient tankless water heater installation.
4. Energy Efficiency: Newer tankless models often boast improved energy efficiency, which could lead to significant long-term savings on utility bills.

Should a replacement be the more prudent choice, we can guide you through the options for a new Navien Tankless Water Heater or other high-efficiency models.
