When your tankless water heater stops working, it brings your daily routine to an abrupt halt.

For homeowners in Simi Valley, a malfunctioning tankless unit requires a specialized solution from technicians who understand the intricate technology inside these efficient systems. At AirWorks Solutions, we provide comprehensive tankless water heater repair in Simi Valley, CA, designed to accurately identify the root cause of any issue and restore your hot water supply promptly and professionally.

Identifying the Signs of a Failing Tankless Water Heater

Tankless water heaters are sophisticated appliances that often signal problems in specific ways. Recognizing these symptoms early can prevent more significant damage and lead to a faster, more effective repair. If you are experiencing any of the following issues, your unit requires professional attention.

No Hot Water or Lukewarm Water

This is the most obvious and disruptive symptom. It can be caused by a complete ignition failure, a faulty heating element in an electric model, or a malfunctioning gas valve. Sometimes, the issue is a clogged internal filter or a flow sensor that isn't detecting water movement, preventing the unit from activating.

Fluctuating Water Temperatures

If your water temperature swings between hot and cold, it could be a sign of a "cold water sandwich," where the unit struggles to maintain a consistent output. This is often caused by a faulty flow sensor, a malfunctioning thermistor that reads temperatures incorrectly, or mineral buildup that insulates the heat exchanger.

Error Codes Displayed on the Unit

Modern tankless heaters use a digital display to report specific error codes. These codes are invaluable diagnostic tools for a trained technician. Common codes may indicate:

• Ignition Failure (e.g., Code 11): The unit is trying but failing to ignite the burner.
• Flow Sensor Issue: The system cannot detect water flow and therefore won't heat.
• Overheating or Temperature Sensor Failure: A safety sensor has tripped or is providing faulty readings.
• Ventilation Blockage: The exhaust system is compromised, creating a serious safety hazard.

Reduced Water Flow or Pressure

A noticeable drop in hot water pressure often points directly to mineral scale buildup. Simi Valley's water can contain minerals that accumulate inside the narrow pipes of the heat exchanger over time. This limescale restricts water flow, forcing the unit to work harder and eventually leading to system failure if not addressed.

Unusual Noises

While tankless units are generally quiet, new or loud noises are a cause for concern. A rumbling or kettling sound often indicates significant mineral buildup boiling inside the heat exchanger. Clicking or ticking sounds can point to a failing ignition system, while a loud humming might suggest an issue with an internal fan or motor.

Visible Leaks or Water Damage

Any water leaking from the unit itself or its connections is a serious problem. Leaks can originate from a cracked heat exchanger, a corroded valve, or a loose pipe fitting. Ignoring a leak can lead to extensive water damage and potential internal short circuits in the unit's electronics.

Our Comprehensive Diagnostic and Repair Process

A successful tankless water heater repair goes beyond simply fixing the immediate symptom. It involves a meticulous process to ensure the entire system is functioning correctly, safely, and efficiently. Our approach is built on precision and expertise.

First, our technicians perform a thorough diagnostic inspection. This includes checking for error codes, testing the electrical components, measuring gas pressure, and assessing the condition of the ventilation system. We inspect the igniter, flame rod, flow sensors, thermistors, and other critical parts to pinpoint the exact point of failure.

Once the problem is identified, we explain the issue clearly, outlining the necessary steps for repair. Our repair solutions are comprehensive and tailored to the specific needs of your unit. This may involve flushing the system to remove mineral scale, replacing a faulty component with high-quality parts, or recalibrating sensors for accurate performance. We specialize in a wide range of repair services, including system descaling, igniter and sensor replacement, valve repair, and addressing ventilation blockages.

After the repair is complete, we don’t just leave. At AirWorks Solutions, we conduct a full system test, running hot water at multiple fixtures to verify that temperature output is consistent, pressure is restored, and the unit is operating according to manufacturer specifications.

When to Repair vs. Replace Your Tankless Water Heater

A common question for homeowners in Simi Valley is whether to invest in a repair or consider a full replacement. We provide honest, expert guidance to help you make the most cost-effective decision. Several factors influence this choice:

• Age of the Unit: Tankless water heaters have a long lifespan, often 15 to 20 years or more. If your unit is less than 12-15 years old, a repair is almost always the more economical option.
• Cost of the Repair: If the cost of a repair, such as replacing a major component like the heat exchanger, approaches a significant percentage of the cost of a new unit, replacement might be a better long-term investment.
• Frequency of Breakdowns: A unit that requires frequent service calls may be nearing the end of its reliable service life. Investing in a new, more dependable model can provide peace of mind and greater efficiency.
• Performance and Efficiency: Newer tankless models offer improved energy efficiency and enhanced features. If your current unit is an older, less efficient model, upgrading can lead to long-term savings on your utility bills.

Our goal is to provide a lasting solution. We will assess your unit’s condition and present you with all viable options, ensuring you have the information needed to choose the best path forward for your home.
