Tankless Water Heater Repair in Albuquerque

Tankless brands we service

Every major tankless brand sold in the ABQ metro: Rinnai, Navien, Noritz, Rheem, Bosch, Takagi, Eemax, and Stiebel Eltron. Our techs are factory-trained on Rinnai and Navien specifically — the two units we see most in Northeast Heights and Rio Rancho new construction.

Common tankless issues at altitude

Mineral scale lockout

ABQ's 200 to 400+ ppm tap water turns the heat exchanger into a calcium reef. Code 11 (no ignition), 12 (flame failure), and LC (scale buildup) are the three we clear most. Vinegar descale every 6 to 12 months prevents 90% of these calls.

Flow sensor failure

Sediment fouls the flow sensor turbine. Unit won't fire even though water's running. We pull the sensor, clean the magnet, and reset the fault.

Combustion air starvation

Thinner air at 5,300 feet plus a clogged intake screen leans the air-fuel mix dangerously. Code 14 lights up. We clean intake, check vent run, retune burner.

Igniter and flame rod

Carbon buildup on the igniter or flame-sense rod stops ignition. Cleaning fixes it 80% of the time, replacement the other 20%.

Tankless descaling — why it's not optional in ABQ

Every Albuquerque tankless owner needs a vinegar flush at least once a year. Twice if the home pulls hard from a well, common in Corrales and Placitas. Without it, a $2,800 unit bricks itself in 4 to 6 years instead of running 20.

• Isolate the unit at the service valves
• Pump four gallons of white vinegar through the heat exchanger for 45 minutes
• Flush with fresh water until clear
• Inspect inlet filter, intake, and burner
• Run a combustion check and fault-code clear
