Ignition Failure Repair in Los Lunas, 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.

Emergency Tankless Repair in Los Lunas

Recirculation Pump Repair in Los Lunas

Common causes of failure include mineral buildup from hard water, ignition problems, faulty flow sensors, clogged air filters, exhaust venting issues and electrical component failures. Regular maintenance, including descaling, can prevent most of these problems.

Yes, our technicians are trained and experienced in repairing all major tankless water heater brands, including Rinnai, Navien, Noritz, Rheem, Bosch, A.O. Smith and more. We carry a wide range of common parts for various models.
Fluctuating temperatures can come from low flow rates, a dirty inlet filter, a failing flow sensor or scale on the heat exchanger. Crossed hot and cold lines at a fixture can cause it too.
