Small Heating Problems Usually Signal Bigger Ones
Heating issues rarely announce themselves clearly at first. An uneven room, a system that cycles too often, or a utility bill that keeps climbing can each point to something deeper inside your equipment. At Kenco Plumbing & Drains, we assess your system directly, whether it is a boiler losing pressure, a furnace struggling to distribute heat, or an oil burner that needs calibration or replacement. Once we understand the cause, we recommend a solution based on the actual condition of your system, not a one-size-fits-all approach. That may mean a targeted repair or a full installation depending on what we find. Every job is handled by licensed and insured technicians following proper standards and local code, with a focus on long-term reliability and preventing the same problem from coming back.

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.
