Tankless Water Heater Repair in West Ashley, SC

Common Tankless Water Heater Problems We Solve in West Ashley

Tankless water heaters, while highly efficient, can encounter specific issues that disrupt their performance. Our experienced technicians are adept at diagnosing and resolving a wide range of problems, ensuring your system operates reliably.

1. No Hot Water / Insufficient Hot Water: This is perhaps the most frustrating issue. Common culprits include ignition failure in gas models, a clogged flow sensor preventing the unit from recognizing water demand, or a restricted gas or water supply. We meticulously check all components to pinpoint the exact cause.
2. Fluctuating Water Temperature: If your water fluctuates in temperature, it could indicate issues with water flow rates, a malfunctioning temperature sensor, or even minor scaling affecting the heat exchange process. We can calibrate sensors and address flow inconsistencies.
3. Decoding Tankless Water Heater Error Codes: Modern tankless units display error codes to signal specific malfunctions. While these codes (such as E02, E11, E12, 11, 12, 90, 99, A00) vary by brand (Rinnai, Noritz, Rheem, Navien, Bosch, Takagi, and others), they generally point to issues like ignition failure, exhaust blockages, overheating, or water flow errors. Our technicians are trained to interpret these codes and perform the necessary diagnostics to resolve the underlying problem. Relying on professional interpretation ensures the correct and safest repair.
4. Mineral Buildup (Scaling): Hard water is a common issue in many areas, and over time, minerals can accumulate inside the heat exchanger, forming scale. This "silent killer" reduces efficiency, restricts water flow, and can lead to overheating and premature component failure. Our services include thorough descaling to restore your unit's performance.
5. Strange Noises (Banging, Popping, Gurgling): Unusual sounds emanating from your tankless unit often indicate a problem. Banging or popping might suggest significant mineral buildup causing water to boil unevenly, while gurgling could point to air in the system or minor blockages.
6. Leaks from Your Tankless Unit: Any visible leak, whether from connections, the pressure relief valve, or the unit itself, requires immediate attention to prevent water damage and further system degradation. We accurately locate and repair the source of the leak.
7. Ignition & Gas Supply Issues: For gas tankless models, problems with the igniter, flame sensor, or gas valve can prevent the unit from firing up or maintaining a flame, leading to a lack of hot water. We safely inspect and repair these critical components.
8. Low Water Pressure: While low water pressure can stem from various plumbing issues, if it's specific to your hot water supply from the tankless unit, it might be due to significant scale buildup inside the heat exchanger or a failing flow sensor.
9. Ventilation & Exhaust System Problems: Proper ventilation is crucial for the safe operation of gas tankless water heaters. Blockages or damage to the exhaust system can lead to unit shutdowns or, more critically, the accumulation of harmful gases. We ensure your venting is clear and functional.

Clear Signs Your West Ashley Tankless Water Heater Needs Professional Attention

Beyond obvious breakdowns, your tankless water heater often provides subtle clues that it needs professional attention. Being aware of these signs can help you prevent more extensive and costly repairs down the line:

1. Persistent Error Codes: If your unit frequently displays an error code that a simple reset doesn't clear.
2. Sudden Loss of Hot Water: While not always an error code, a complete lack of hot water is a clear sign.
3. Discolored or Rusty Water: Indicates corrosion within the unit or your plumbing system.
4. Unusual or Louder Noises: Any new banging, popping, gurgling, or hissing sounds.
5. Increased Energy Bills for Hot Water: A sudden spike suggests your unit is working harder and less efficiently.
6. Visible Leaks: Even small drips should be investigated immediately.
7. Foul Odors: Especially a rotten egg smell, which indicates a gas leak and requires immediate evacuation and professional assistance.

Repair or Replace? Expert Guidance for West Ashley Homeowners

Deciding whether to repair your existing tankless water heater or invest in a new one can be a complex decision. Holy City Heating & Air, LLC provides honest, unbiased assessments to help West Ashley homeowners make the most cost-effective and beneficial choice for their specific situation. We consider several key factors:

1. Age of Your Unit: While tankless water heaters generally last 20 years or more with a proper maintenance plan, an older unit experiencing frequent breakdowns might be nearing the end of its lifespan.
2. Severity and Frequency of Issues: A minor repair might be cost-effective, but if you're facing a major component failure (like the heat exchanger) or consistent, recurring problems, the cumulative cost of repairs can quickly approach the price of a new unit.
3. Long-Term Energy Savings: Newer tankless models often boast significantly higher energy efficiency ratings. If your current unit is older and consumes more energy, a new, more efficient tankless model could lead to substantial long-term savings on your utility bills, offsetting the initial investment. Our experts can discuss your options for a new, more efficient tankless model as part of our comprehensive plumbing services.
4. Budget Considerations: We understand that unexpected expenses can be challenging. We provide clear comparisons of repair costs versus replacement costs and discuss available financing options to help you make an informed decision that aligns with your financial plan.

What to Do Until Our Tankless Technician Arrives (Safety First!)

If your tankless water heater is malfunctioning, taking a few immediate, safe steps can help prevent further issues or ensure your safety until our technician arrives:

1. Turn Off the Water Supply: Locate the cold water inlet valve near your tankless unit and turn it off to prevent water flow, especially if you notice a leak.
2. Turn Off the Gas Supply (if applicable): For gas models, locate the gas shut-off valve near the unit and turn it to the "off" position.
3. Turn Off the Power: Find the circuit breaker corresponding to your water heater in your electrical panel and switch it off.
4. Avoid DIY Repairs: Unless it's a simple reset procedure outlined in your owner's manual, avoid attempting complex repairs. Tankless water heaters involve high voltage and gas lines, which can be dangerous for untrained individuals.
