Flow Sensor and Thermistor Repair in South Lyon
Tankless heaters rely on 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 accurate.
Noritz Tankless Water Heater Repair in South Lyon, MI
Noritz tankless heaters are known for their sturdy design, but can sometimes face issues such as flow sensor malfunctions or venting problems. We provide dedicated repair services for Noritz units in South Lyon, MI, ensuring proper combustion, water flow and exhaust, which are essential for safe and efficient operation.
Condensing Tankless Repair in South Lyon, MI
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 inspected for slope and sagging.
Tankless Repair vs Replacement Cost in South Lyon, MI
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.
Emergency Tankless Repair in South Lyon
A tankless unit that leaks internally or shows a fault you cannot clear needs prompt attention. We put first no-hot-water calls and arrive with common sensors, igniters and filters. If a major component like a heat exchanger has failed, we check warranty coverage and order the part. We can often restore partial operation in the meantime.
Ignition Failure Repair in South Lyon, MI
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.

Gas tankless water heaters require correct gas pressure and proper ventilation for safe operation. Issues can range from gas valve failures to carbon monoxide sensor errors.

Frequently Asked Questions About Tankless Water Heater Repair in South Lyon
The cost of tankless water heater repair in South Lyon varies widely 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.
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.
Error codes can be caused by a variety of issues, such as low water flow, gas supply problems, ignition failures, exhaust blockages or faulty temperature sensors. Each code points to a specific system malfunction.
We stand behind our tankless water heater repairs with a comprehensive warranty on both parts and labor. The exact warranty period will be discussed with you before any work begins, providing you peace of mind.
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.
In homes with hard water and no softener, once a year is a good rule. Homes with a softener may go longer, but annual inspection is still wise.
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.
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 find the cause.
