Choosing a Navien Tankless Installer in Sacramento: 6 Questions to Ask
A Navien tankless unit is only as good as its installation. Ask these six questions before you hire anyone.

Key takeaways
- Ask how the installer sizes the gas line and the unit.
- Confirm venting, condensate and service valves are included.
- Choose an installer who also services Navien units.
Navien tankless water heaters are excellent, but installation quality decides whether you get years of trouble-free hot water or a string of error codes.
The six questions
- How will you size the unit for my household?
- Will you check and upgrade the gas line if needed?
- What venting will you use, and where will it exit?
- Is a condensate neutralizer included?
- Will you install isolation valves for descaling?
- Do you service and repair Navien units after the install?
