Emergency Tankless Repair in Bay City
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.
Flow Sensor and Thermistor Repair in Bay City
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 failed parts. Temperature becomes steady again once readings are accurate.
