We're excited to share that Stedman's Plumbing is now a certified Navien Service Specialist (NSS) — one of a select group of plumbing companies nationwide to earn this designation directly from Navien, one of the world's leading manufacturers of tankless water heaters and combination boilers.

This isn't a directory listing or a paid badge. The Navien Service Specialist program requires real training, demonstrated competency, and ongoing commitment to the brand's standards. Here's what it means — and why it matters for our customers.

What Is the Navien Service Specialist Program?

The Navien Service Specialist (NSS) program is Navien's official certification for plumbing and HVAC companies who specialize in the installation, service, and repair of Navien products. NSS members are recognized on Navien's website as approved installers and service providers — one of the most trusted signals a Navien customer can look for when choosing a contractor.

To become an NSS, Stedman's Plumbing completed Navien's advanced training program covering:

• Tankless water heater installation — including venting, gas supply sizing, and condensate management for condensing units
• Combination boiler installation and service — space heating and domestic hot water in a single unit
• Diagnostic troubleshooting — interpreting Navien error codes, testing heat exchangers, and resolving common failure modes
• Best practices for efficiency and performance — proper manifolding, recirculation system setup, and optimal temperature settings
• Service, Installation, and Operation Manuals — across Navien's full residential product range

What NSS Members Get — And Why That Helps You

The NSS program isn't just a title. It comes with tangible benefits that translate directly into better service for our customers:

• Priority technical support — Dedicated NSS hotline directly into Navien's service team for faster resolution
• Fast parts access — Streamlined Return Goods Authorization (RGA) process means quicker turnaround on warranty parts
• Discounted parts kit — We stock Navien's most common service parts so we can resolve most issues in a single visit
• Listed on Navien's website — Customers searching Navien's locator tool will find Stedman's as an approved provider in Fresno
• Higher pay rate structure — NSS agents receive a higher compensation rate for warranty work, which means Navien incentivizes quality service

Why Navien?

Navien has built a strong reputation in the tankless water heater market for a reason. Their condensing technology consistently ranks among the most efficient available, and their NPE series tankless units are a favorite of California homeowners due to the state's energy efficiency requirements.

Key reasons we recommend and service Navien products:

• Industry-leading efficiency — up to 0.96 UEF on select models, qualifying for utility rebates in California
• Condensing technology — extracts more heat from combustion gas, lowering operating costs
• ComfortFlow® technology — built-in buffer tank and recirculation pump eliminates the "cold water sandwich" common in tankless units
• Wide product range — residential tankless, commercial tankless, and NHB combination boilers
• NaviLink® Wi-Fi control — remote monitoring and control via smartphone app

Is a Navien Tankless Right for Your Home?

Tankless water heaters aren't for every home — and as NSS-certified specialists, we'll always give you an honest assessment. A Navien unit is generally an excellent fit if:

• Your household has moderate-to-high hot water demand
• You want to reduce energy bills and your water heating carbon footprint
• You have adequate gas supply for a condensing tankless unit (or are willing to upgrade the supply line)
• You have or are willing to install proper condensate drainage
• Your existing vent configuration is compatible or upgradeable

If a tankless isn't the right fit, we'll tell you — and recommend the best alternative for your specific situation. That's the Stedman's way.
