If your Kensington home has a Noritz and it's showing a code like 11, 12, or 90, don't give up on it yet. Most Noritz issues come from ignition, flame sensing, venting, or scale — and those are repairable.
Noritz symptoms we fix
- Water gets hot, then cold, then hot again
- Fan runs but no ignition
- Low flow at the tap
- Unit beeps or displays a maintenance warning
- Visible scale or white residue at the inlet filter
- Error codes (ignition failure, flame loss, or combustion/vent related)
Common Noritz fixes
Cleaning or replacing the flame rod, clearing vent blockages, fixing low gas pressure, cleaning the inlet water filter, and descaling the heat exchanger. On older non-condensing models, we also check the stainless vent for corrosion.
Kensington homes: what we see
Tight mechanical spaces in older Kensington homes are where compact Noritz units shine, but vent routing through old masonry takes planning.
Most Kensington homes are on WSSC Water, which licenses plumbers in its service area and runs the cross-connection (backflow) program. Mineral buildup still happens over time, which is why flushing tanks and descaling tankless units pays off.
Repair vs. replace
A Noritz that's 15+ years old with a failing heat exchanger is usually a replacement candidate. Anything else — sensors, igniters, fans, circuit boards — is typically worth repairing. We'll lay out both options with prices.
New Noritz installs
Current condensing Noritz models (such as the EZ series, designed as a tank replacement) can often use your existing water and gas connections with minimal changes. We still verify gas line size and vent length before recommending one.
