Tankless Water Heater Descaling Service in Des Moines
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, reducing efficiency and eventually causing breakdowns. Water across much of Iowa comes from groundwater and runs hard to very hard, so scale buildup in water heaters and fixtures is common. Our descaling service in Des Moines involves flushing the unit with a specialized cleaning solution to dissolve these mineral deposits. This preventative maintenance and repair step is key for extending the lifespan of your tankless heater and keeping it at peak performance.

Tankless Water Heater Error Code Diagnostics in Des Moines, IA
Modern tankless water heaters display error codes to flag specific problems, from flow rate issues to combustion errors. Our experts in Des Moines, IA are trained to interpret these codes accurately, using dedicated diagnostic tools to pinpoint the exact component failure. This accuracy allows us to quickly order the correct parts and perform targeted repairs, saving you time and money. We address codes related to burner failures, fan issues and temperature sensor errors, and more.
Ignition Failure Repair in 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.

Recirculation Pump Repair in Des Moines
Many tankless systems use internal or external recirculation to deliver hot water faster. Pump failures, check valve problems or wrong schedule settings can cause long waits or lukewarm water. We test the pump, check valves and controls and set the schedule to match your routine. A properly tuned system saves both water and gas.
Condensing Tankless Repair in Des Moines, IA
Condensing tankless heaters, such as many Navien models, extract extra heat from exhaust and produce condensate. Clogged condensate traps, failed neutralizers and blocked drains can shut the unit down. We clean the trap, replace the neutralizer media and confirm proper drainage. PVC venting is also checked for slope and sagging.

No Hot Water Tankless Repair in Des Moines
When your tankless unit fails to produce hot water, it is often due to issues with the ignition, gas supply or a clogged heat exchanger.
