Navien tankless water heater repair — Boulder, CO
Last updated: September 24, 2026
What affects the price
Replacing a water heater involves several variables that change the final bill. The main factors are the type of unit you choose—like standard tank models versus tankless systems—and the fuel source, whether gas or electric. Installation complexity also plays a role, especially if we need to update venting, gas lines, or electrical wiring to meet current building codes. Relocating a unit or upgrading to a higher capacity will also shift the bottom line.
About this service
Navien tankless units are sophisticated systems that rely on precise electronic sensors and gas flow management. If your unit displays an error code, fails to ignite, or produces lukewarm water, it likely needs professional diagnostic services to check the flame sensor or flow valves. We perform repairs by inspecting the heat exchanger and venting systems to ensure safe operation. Contact us if your system isn't performing as expected so we can restore your consistent flow of hot water.
