Tankless Water Heater Repair Repair Frequently Asked Questions

Why does my tankless water heater produce cold water at times?

Cold water bursts can be caused by several issues, including a flow sensor problem, mineral scale buildup, or a component that isn't heating consistently. This issue can happen more often as the unit ages or when it hasn't received regular maintenance.

Andgar Home Comfort technicians diagnose the real issue before recommending any fix, so you know exactly what's causing the problem. We work on tankless systems from AO Smith, Rinnai, and Navien, among other brands, so most repairs can move forward without delay.

Why is my tankless water heater displaying an error code?

Error codes are built into most tankless systems to flag a specific issue, such as a venting problem, an ignition failure, or a sensor malfunction. The exact meaning of the code can vary by brand and model, so it helps to have a technician confirm what's actually going on.

Andgar Home Comfort technicians are familiar with a wide range of tankless brands and models, so they can accurately interpret what the code is telling you. We identify the specific component causing the issue, so you're not paying to replace parts that don't need it.

Why has my tankless water heater's hot water output decreased?

Reduced hot water output is often caused by mineral scale buildup inside the unit, especially in areas with harder water. Over time, this buildup can restrict flow and reduce how efficiently the system heats water.

Andgar Home Comfort technicians can flush the system to address scale buildup and restore performance. Regular maintenance can help you avoid this issue and keep your unit running efficiently between visits.

How much does it cost to repair a tankless water heater?

The price of a tankless water heater repair may depend on several factors, including the age of the unit, the level of component wear, and the specific brand or model. Every repair is different, so an accurate price can only be given after a proper diagnosis.

Andgar Home Comfort provides upfront pricing, so the price you're quoted is the price you pay. We service tankless systems of many ages and brands, so we can often find a solution even for older units.
