What Feels Minor Can Run Deeper Than You Think
Heating systems tend to give subtle warnings before they fail. A cold spot that should not be there, a system that runs longer than it used to, or an energy bill creeping higher each month are all signs worth paying attention to. At Kenco Plumbing & Drains, we get to the bottom of it rather than patching over the symptom. Whether your boiler is losing efficiency, your furnace is failing to keep up, or your oil burner needs a closer look, we evaluate the actual state of your equipment before recommending anything. From there, we present tiered options so you can weigh a targeted repair against a longer-term solution and decide what makes sense for your home and your budget. The work is carried out by licensed and insured technicians held to proper code standards, with every decision aimed at keeping the problem from returning.
Customer Reviews
Our 5-Star Feedback
Called out again on 4-28-2026, on an “emergency” per tenant Paige and Hayden rushed and addressed the issue within 10 or 24 minutes. They took care of the problem aThey, and everyone I have worked with at Kenco is knowledgeable, efficient and does a great job.

The Price Is Set Before We Pick Up a Tool
Nobody should be left wondering what a heating job is going to cost until after it is done. At Kenco Plumbing & Drains, you get a clear picture of what we found, what your options are, and what each one costs before anything is scheduled. We do not layer in extras or steer you toward a bigger job than what your system actually needs. If you are looking at a larger investment like a full boiler or furnace replacement, we offer financing through Hearth and Wisetack to help spread the cost into payments that work for you. Whether you are paying upfront or financing the work, you will know exactly where things stand before we ever start.
Dover Gets the Same Care We Give Every Home We Work In
Kenco Plumbing & Drains works across the Seacoast NH region every day, and Dover is a community we know well. Homes here run the full range, from older builds still relying on oil heat and aging boiler setups to newer construction with modern high-efficiency systems that need a different kind of attention. Oil burner service is something we specialize in, and it is a skill set that is harder to find than most homeowners realize. Our team has the hands-on experience to handle all of it without cutting corners. When a New Hampshire winter sets in and a heating system gives out, the turnaround matters as much as the repair itself. We take that seriously, and we stand behind every result.
FAQs
Answers You Can Rely On
Can a more efficient system actually lower my energy costs?
Yes, modern systems are designed to use less energy while maintaining consistent temperatures. With proper installation, that efficiency can lead to noticeable savings
How do I know if I need a new heating system or just a repair?
If your system is frequently breaking down, struggling to keep up, or causing higher energy bills, replacement may be the better long-term option. For smaller issues or newer systems, a repair can often restore proper performance.
How often should my heating system be serviced?
Heating systems should typically be serviced once a year to maintain efficiency and catch potential issues early. Routine maintenance helps extend the life of your equipment and reduce the risk of breakdowns.
What types of heating systems do you install?
We install boilers, furnaces, and complete HVAC heating systems. Each option is selected based on your home’s layout, size, and overall comfort goals.
