Factory Certification That Makes a Difference
Dees Plumbing & Heating is proud to be listed as an official Navien Certified Installer on Navien’s website at navieninc.com/installers. This certification means our technicians have completed rigorous training directly from Navien, giving us specialized knowledge that typical plumbing contractors simply don’t have.

By choosing a certified installer from the start, homeowners in Collinsville, Kenwood, and throughout Dracut avoid these costly problems entirely.
Our certification provides you with:

Serving New Homebuyers Throughout Middlesex County
Buying your first home near the Merrimack River in Lowell or relocating to a peaceful neighborhood in Tewksbury is exciting. But aging heating systems can quickly turn that excitement into expensive headaches. Many homes in our service area still rely on outdated tank water heaters or inefficient boilers that waste energy and space.
According to Mass Save data, over 40,000 Massachusetts homes upgraded their heating systems in 2024 alone, with many choosing tankless water heaters for their efficiency and reliability. As a Navien service installer, we help new homeowners make smart decisions about their heating infrastructure from day one.
We understand the unique challenges of homes in our region. Whether you’re purchasing a historic colonial in Andover or a modern ranch near Four Oaks Country Club in Dracut, our team evaluates your specific needs and recommends the right Navien model for your household size, water usage patterns, and budget.
Supporting New Businesses Opening in Lowell and Beyond
Commercial property owners and entrepreneurs opening new businesses in Lowell’s growing downtown district, along Route 110 in Dracut, or in Andover’s business corridors need heating systems that won’t let them down. Restaurant owners, retail shop managers, and office building operators all depend on consistent hot water and reliable heating.
Navien’s commercial-grade systems deliver endless hot water without the massive footprint of traditional tank systems. For businesses where space is at a premium, this wall-mounted technology frees up valuable square footage while providing superior performance.
As your local Navien service provider, Dees Plumbing & Heating offers:
- Emergency service calls for unexpected breakdowns
- Scheduled maintenance programs to prevent costly downtime
- Installation consultations for new construction or renovations
- Same-day repairs using our in-stock Navien parts inventory
Understanding Navien Technology: Why Certification Matters
Navien tankless water heaters and condensing boilers represent cutting-edge heating technology. Unlike conventional systems, they use sophisticated electronics, precise gas controls, and specialized venting systems. These advanced features deliver exceptional efficiency ratings of 0.95 to 0.97 EF, qualifying for Energy Star certification and helping homeowners save up to 50 percent on energy costs.
However, this technology requires specialized knowledge to install correctly. A certified Navien installer understands the critical importance of proper gas pressure, condensate drainage, venting materials, and electrical connections. Small installation errors that might seem insignificant can lead to error codes, premature wear on components, or complete system failure months or even years down the road.
The truth is, Navien systems are so well-engineered that they can initially overcome minor installation mistakes. This means problems might not surface immediately, leading homeowners to believe their system is fine when it’s actually working harder than necessary or heading toward an early failure. By choosing Dees Plumbing & Heating as your certified Navien service installer, you eliminate this risk entirely.

The Financial Benefits of Choosing Navien
Massachusetts residents benefit from some of the most generous heating system incentives in the country. Through Mass Save programs, homeowners can access rebates and zero-interest HEAT loans of up to $50,000 to support energy-efficient upgrades. Federal tax credits of up to $2,000 are also available for qualifying systems installed by the end of 2025.
When you combine these incentives with the energy savings Navien systems provide, the financial case becomes compelling. With natural gas being the primary heating fuel for approximately 50 percent of Massachusetts households, and heating costs representing a significant portion of annual home expenses, upgrading to a high-efficiency Navien system can deliver measurable savings month after month.
As your certified Navien service provider, Dees Plumbing & Heating helps you navigate available rebates and incentives, ensuring you maximize your savings on both the purchase and ongoing operation of your new system.
Why Navien Systems Are Perfect for New England Homes
Navien’s engineering specifically addresses the challenges of cold-climate performance. Their systems include features like stainless steel heat exchangers that resist corrosion, advanced diagnostics for easy troubleshooting, and built-in freeze protection for harsh Massachusetts winters.
For homes with hard water common in parts of our service area, Navien’s design minimizes scale buildup and includes easy-access maintenance points. The compact wall-mounted design works perfectly in the smaller mechanical rooms typical of New England homes, and the quiet operation won’t disturb your household or business.
Frequently Asked Questions About Navien Service & Installation
What should I look for in a Navien service provider near me?
Always verify that the contractor is listed as a certified Navien installer on the manufacturer’s website. Certified installers have completed factory training, maintain relationships with Navien technical support, and stock genuine replacement parts. Ask about their experience with your specific model and whether they offer emergency service to your area.
How often should I schedule maintenance for my Navien system in Massachusetts?
We recommend annual professional maintenance for Navien tankless water heaters and boilers. In areas with hard water, which is common throughout the Merrimack Valley, you may benefit from more frequent descaling services. Regular maintenance prevents mineral buildup, ensures efficient operation, and helps identify potential issues before they become expensive repairs.

Yes! As a local Navien certified installer with a comprehensive parts inventory, we complete most repairs the same day we’re dispatched. Our service area includes Dracut, Lowell, Andover, Tewksbury, and surrounding communities throughout Middlesex County. We understand that heating and hot water emergencies can’t wait, which is why we prioritize quick response times.
Are Navien systems good for new construction or business renovations?
Absolutely. Navien systems are ideal for new construction and renovation projects. Their compact size maximizes usable space, and their high efficiency helps new buildings meet modern energy codes. For commercial applications like restaurants, salons, medical offices, or retail spaces, Navien’s endless hot water capability and reliable performance make them an excellent choice.
What makes Dees Plumbing & Heating different from other plumbers in the area?
Our Navien certification sets us apart. While many plumbers can install water heaters, certified Navien installers receive specialized training on these sophisticated systems. We understand the precise gas pressures, venting requirements, and electrical connections that ensure optimal performance. Our certification also gives us direct access to Navien’s senior technical support team and a reliable supply of genuine parts.
Can Navien systems help me save money on energy bills?
Yes. Navien systems typically achieve efficiency ratings of 0.95 to 0.97 EF, which means they convert nearly all the fuel they use into usable heat.

Combined with available rebates and tax credits, the long-term savings are substantial.
