Ignition Failure Repair in Johns Creek, GA
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 common hidden cause when a tankless unit replaced a tank. We correct the issue so the unit lights every time.
Flow Sensor and Thermistor Repair in Johns Creek
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 faulty parts. Temperature becomes steady again once readings are correct.
Recirculation Pump Repair in Johns Creek
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.
Commercial Tankless Water Heater Repair in Johns Creek
Commercial tankless water heaters in Johns Creek face heavier usage and require robust repair solutions. Whether it is for a restaurant, hotel or office building, we understand the urgency of maintaining hot water availability. Our commercial tankless water heater repair services address larger capacity units, complex manifold systems and often more serious scaling issues. We prioritize fast, efficient service to minimize disruption to your business operations.
Tankless Repair vs Replacement Cost in Johns Creek, GA
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.
Tankless Descaling and Flushing in Johns Creek
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 wise for most homes on hard water.
No Hot Water Tankless Repair in Johns Creek
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. Our technicians in Johns Creek will carefully diagnose the root cause, whether it is a faulty igniter, a pressure sensor fault or mineral buildup. We carry common replacement parts for quick fixes, restoring your continuous hot water supply efficiently. We also check for proper venting, which is essential for the safe operation of your unit.
Pilot Light and Ignition Repair in Johns Creek, GA

Municipal water across much of the northern half of Georgia comes from rivers and reservoirs and tends to run fairly soft, which is gentle on fixtures and water heaters. Tankless heaters scale up when water is hard, so careful repair and regular descaling are what keep these high-efficiency units running for their full lifespan.

Frequently Asked Questions About Tankless Water Heater Repair in Johns Creek
The cost of tankless water heater repair in Johns Creek 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 diagnosing the specific problem.
Minor repairs usually do not require a permit. If the repair involves major changes to the gas or water lines, or if the unit itself is being replaced, a permit from the Johns Creek building department may be necessary. We handle all necessary permitting for you.
Regular professional maintenance, including descaling and checking all connections, is the best prevention. Installing a whole-home water softener can also greatly reduce mineral buildup in areas with very hard water.
This often comes from low gas pressure, a blocked intake or exhaust, a dirty flame rod or overheating from scale. We test each possibility to pinpoint the cause.
Many common tankless water heater repairs can be completed 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 maintenance like filter cleaning can be done by homeowners, complex repairs involving gas lines, high voltage electricity or intricate internal components should always be left to a licensed professional. DIY attempts can be dangerous and cancel warranties.
