No Hot Water Tankless Repair in Santa Fe
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 Santa Fe will carefully diagnose the root cause, whether it is a faulty igniter, a pressure sensor malfunction 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 crucial for the safe operation of your unit.

Tankless Descaling and Flushing in Santa Fe
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.
Recirculation Pump Repair in Santa Fe
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.
Tankless Repair vs Replacement Cost in Santa Fe, NM
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 usually ranges from $3,000 to $5,500. We compare these costs against the age and condition of your unit.

A sudden loss of hot water can be an emergency, especially on a cold morning in Santa Fe, NM. GVK Plumbing offers emergency tankless water heater repair to address critical failures promptly. We are available to troubleshoot issues like major leaks, complete system shutdowns or persistent error codes that prevent any hot water production. Our fast response team works quickly to restore your hot water, often on the same day.
Ignition Failure Repair in Santa Fe, NM
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 reliably.
Gas Tankless Water Heater Repair in Santa Fe
Gas tankless water heaters require precise gas pressure and proper ventilation for safe operation. Issues can range from gas valve failures to carbon monoxide sensor errors. Our certified technicians in Santa Fe perform thorough diagnostics on gas lines, igniters and exhaust systems, so your unit is both functional and safe.
