What's Included in Our Tankless Water Heater Maintenance Service
Our tankless water heater services go beyond a quick inspection. We pay attention to the details, including cleaning critical components, confirming safe operation, and identifying potential issues before they affect your hot water supply.
Below is an overview of what a standard tankless hot water heater maintenance service includes:
Descaling and Flushing the System
Over time, minerals naturally found in water can accumulate inside a tankless water heater. This buildup can restrict heat transfer and lead to corrosion if left untreated.
Descaling and flushing the system helps remove these deposits and keep your heater running smoothly. While flushing, our team will circulate a cleaning solution through the unit to break down mineral buildup inside the heat exchanger.
Cleaning the Inlet Filter and Screen
Tankless water heaters rely on a clean inlet filter to regulate water flow and protect internal parts from debris. If the filter becomes clogged, you may notice less water flow throughout your home.
Keeping this component clean supports efficient operation and reduces strain on the unit. Our maintenance services include removing and cleaning the inlet filter and screen to help ensure steady water flow.
Inspecting Burners and Ignition Components
In gas-powered tankless systems, burners and ignition components play a key role in safely and efficiently heating water. Over time, residue or wear can affect how these parts function.
Identifying signs of wear early can help reduce the risk of unexpected breakdowns. A detailed maintenance service helps catch early warning signs and ensure proper ignition.
Checking Valves, Lines, and Connections
Valves, water lines, and gas connections must remain secure and leak-free for safe operation. During maintenance, our team examines these areas for signs of wear, corrosion, or loose fittings.
This step helps protect against water damage, gas leaks, and performance issues that may not be visible during everyday use.
Testing Temperature and Flow Rates
Proper temperature control and steady flow rates are essential for reliable hot water delivery. Routine tankless water heater maintenance provides peace of mind by addressing both performance and safety. It also allows our trained professionals to recommend next steps if we find early signs of wear or malfunction.
Tankless Water Heater Repair & Replacement Options
Even with regular tankless water heater maintenance, your system can eventually develop issues that require repair or replacement. If routine maintenance reveals worn components or safety concerns, having clear next steps helps prevent extended disruptions to your hot water supply.
Minor issues may be resolved through targeted tankless water heater repairs, such as replacing faulty sensors, valves, or ignition components. Addressing these concerns early can help restore performance and prevent further damage to the system.
In some cases, replacement may be the better long-term solution. Older units, systems with repeated issues, or equipment that no longer meets your household’s hot water demands may benefit from an upgrade.
If you’re unsure whether your system needs maintenance, repairs, or a replacement, our team will inspect your unit and help you find the right solution for your needs and budget.
