Pilot Light & Ignition Repair in West Des Moines, IA
For gas-fired tankless water heaters, a malfunctioning ignition system can completely stop hot water production.

Timely repair of these components prevents hazardous gas problems and restores your unit's ability to heat water on demand.

Condensing Tankless Repair in West Des Moines, IA
Condensing tankless heaters, such as many Navien models, extract extra heat from exhaust and produce condensate.

PVC venting is also checked for slope and sagging.

Tankless Repair vs Replacement Cost in West Des Moines, IA
Descaling service typically costs $175 to $350, and sensor or igniter repairs run $250 to $600. Heat exchanger replacement can cost $800 to $1,500 or more unless covered by warranty. A new tankless unit installed usually ranges from $3,000 to $5,500. We compare these costs against the age and condition of your unit.
Ignition Failure Repair in West Des Moines, IA
If your tankless unit will not fire, the cause may be a dirty flame rod, a bad igniter, low gas pressure or a blocked intake. We test each component and measure gas pressure at the inlet. Undersized gas lines are a frequent hidden cause when a tankless unit replaced a tank. We correct the issue so the unit lights reliably.
Tankless Descaling and Flushing in West Des Moines
Hard water leaves calcium and magnesium scale inside the heat exchanger, restricting flow and causing overheating. Many units warn of this with scale codes, such as the LC code on Rinnai models. We connect a circulation pump to the service valves and run a descaling solution through the exchanger. Annual descaling is a smart move for most homes on hard water.

Flow Sensor and Thermistor Repair in West Des Moines
Tankless heaters use flow sensors to start and thermistors to regulate temperature. A dirty inlet filter or failed sensor causes no hot water, fluctuating temperature or the unit turning off mid-shower. We clean filters, test sensor readings and replace failed parts. Temperature becomes steady again once readings are accurate.

Frequently Asked Questions About Tankless Water Heater Repair in West Des Moines
The cost of tankless water heater repair in West Des Moines varies a lot depending on the issue, ranging from $150 for minor fixes like sensor replacement to $600 or more for complex repairs involving heat exchanger descaling or major component replacements. We provide a detailed estimate after identifying the specific problem.
Many common tankless water heater repairs can be finished within 1 to 3 hours, especially if parts are readily available. More complex issues, like extensive descaling or ordering specialized parts, might take longer and may require a follow-up visit.
While some basic troubleshooting, like checking the power supply or gas valve, can be done, most tankless water heater repairs require special tools and knowledge. Attempting DIY repairs on gas or electrical components can be dangerous and void your warranty. It is always best to call a professional.
Error codes can be triggered by a variety of issues, such as low water flow, gas supply problems, ignition failures, exhaust blockages or faulty temperature sensors. Each code corresponds to a specific system malfunction.
We stand behind our tankless water heater repairs with a solid warranty on both parts and labor. The exact warranty period will be discussed with you before any work begins, providing you peace of mind.
Fluctuating temperatures can come from low flow rates, a dirty inlet filter, a failing flow sensor or scale on the heat exchanger. Crossed hot and cold lines at a fixture can cause it too.
Some homeowners do with a kit if service valves are installed. Diagnosing error codes and replacing sensors, igniters or gas components should be left to a pro.
Regular maintenance, particularly annual descaling, is important for tankless water heaters in homes with hard water. It prevents mineral buildup, maintains efficiency, extends the lifespan of the unit and helps avoid costly repairs by catching small issues before they grow.
