Tankless Water Heater Descaling Service in Des Plaines
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, reducing efficiency and eventually causing breakdowns. Homes supplied by lake water tend to have moderate water, while most of Illinois relies on groundwater that runs hard to very hard. Our descaling service in Des Plaines 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 Plaines, IL
Modern tankless water heaters display error codes to flag specific problems, from flow rate issues to combustion errors. Our experts in Des Plaines, IL are trained to interpret these codes accurately, using specialized 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, among others.
Tankless Repair vs Replacement Cost in Des Plaines, IL
Descaling service usually 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 typically ranges from $3,000 to $5,500. We compare these costs against the age and condition of your unit.
Recirculation Pump Repair in Des Plaines
Many tankless systems use internal or external recirculation to deliver hot water more quickly. 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.
Navien Tankless Water Heater Repair in Des Plaines
Navien units are known for their advanced condensing technology but can sometimes develop issues with their circulation pump or exhaust systems.

Our team is familiar with Navien's parts and troubleshooting protocols, delivering a precise and effective repair that maintains your unit's high efficiency.
Pilot Light & Ignition Repair in Des Plaines, IL
For gas-fired tankless water heaters, a faulty ignition system can completely stop hot water production. Our team in Des Plaines, IL diagnoses issues with igniters, flame sensors and gas valves. We ensure proper gas pressure and ventilation are maintained for safe and efficient operation. Timely repair of these components prevents dangerous gas problems and restores your unit's ability to heat water on demand.
Tankless Descaling and Flushing in Des Plaines
Hard water leaves calcium and magnesium scale inside the heat exchanger, limiting 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.
No Hot Water Tankless Repair in Des Plaines
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.

We carry common replacement parts for fast fixes, restoring your continuous hot water supply efficiently. We also check for proper venting, which is essential for the safe operation of your unit.
