Electric Tankless Water Heater Repair in Ann Arbor, MI
Electric tankless units offer a compact solution but can run into problems with heating elements or circuit breakers. CHV Plumbing offers expert electric tankless water heater repair in Ann Arbor, MI, addressing electrical faults, ensuring proper wiring and replacing faulty elements to restore your hot water supply safely and efficiently.
Ignition Failure Repair in Ann Arbor, 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 frequent hidden cause when a tankless unit replaced a tank. We correct the issue so the unit lights reliably.
Flow Sensor and Thermistor Repair in Ann Arbor
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 correct.
Emergency Tankless Water Heater Repair in Ann Arbor, MI
A sudden loss of hot water can be an emergency, especially on a cold morning in Ann Arbor, MI. CHV Plumbing offers emergency tankless water heater repair to address critical failures promptly.

Our rapid response team works quickly to restore your hot water, often on the same day.
Condensing Tankless Repair in Ann Arbor, 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 verify proper drainage. PVC venting is also checked for slope and sagging.
Pilot Light and Ignition Repair in Ann Arbor, MI
For gas-fired tankless water heaters, a faulty ignition system can completely stop hot water production. Our team in Ann Arbor, MI 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 hazardous gas problems and restores your unit's ability to heat water on demand.

Recirculation Pump Repair in Ann Arbor
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 daily routine. A properly tuned system saves both water and gas.
