We Show Up to Solve, Not Just Service
When a heating system starts to slip, the visible sign is rarely the whole story. Rising energy costs without a clear explanation, heat that takes longer to reach the far end of the house, or equipment that runs longer than it once did all point to something worth digging into. At Kenco Plumbing & Drains, we approach every job by identifying the actual source rather than addressing only what is easy to see. We assess your boiler, furnace, or oil burner directly and walk you through the findings before recommending anything. From there, we present tiered options so you can weigh what makes the most sense for your home and your budget, whether that is a repair that gets things back on track or a replacement that removes the risk of the issue returning. Every job is completed by licensed and insured technicians held to code, with durability driving every decision we make.

You Get the Full Picture Up Front
Nobody wants to navigate a heating repair while already dealing with a cold house. At Kenco Plumbing & Drains, we keep the process as straightforward as the work itself. After assessing your system, we share what we found and what each option costs before anything is scheduled or started. We do not add work that is not warranted, and we do not steer you toward a solution that does not fit your situation. For larger projects like a full boiler or furnace installation, Hearth and Wisetack financing is available to spread the cost without putting pressure on your budget. We are a family-owned team, and the way we handle every job in Exeter reflects how seriously we take that.
We Leave Exeter Warmer Than We Found It
Exeter is a community with deep roots and homeowners who know what they want from the people they hire. Kenco Plumbing & Drains works throughout Seacoast NH and the greater Rockingham County area consistently, which means we bring real familiarity with the heating systems and home types common to this region. From older homes running on oil heat to newer builds with high-efficiency equipment, our team has the experience to handle it all without cutting corners. New Hampshire winters make heating reliability less of a preference and more of a necessity, and we treat it that way on every job. We show up ready, work with care, and do not consider the job finished until the result is something we are proud to put our name on.
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.
