Castle Rock's water leaves mineral scale inside tankless units, which restricts flow and triggers error codes. A unit that worked fine for two years can start shutting off mid-shower.
We descale the heat exchanger with a pump and cleaning solution, flush the inlet filter, and set the customer up on an annual maintenance schedule so the scale never gets that far again.

When groundwater drops into the low 40s, a water heater has to work much harder to raise it to 120 degrees. Tanks that were marginal in summer run out of hot water fast in winter.
We check the unit's recovery rate against the household's actual demand and either repair what's failing or recommend a correctly sized replacement. We also verify the dip tube and heating elements are doing their job.

Terrain and Crystal Valley have a lot of newer homes with tankless and heat pump water heaters. These systems need different diagnostics than a standard tank, and not every plumber stocks the parts.
Our techs are trained on Navien, Rinnai, Noritz, and heat pump units. We carry the sensors, igniters, and control boards these systems need, so we're not making a second trip for parts.
