Experience That Goes Beyond Installation

Heating systems in New England are often complex. Many homes rely on boilers, steam systems, radiant floors, or older hot water setups that require real understanding to service properly.

Since 1989, Kevin has worked with these systems in all stages of their life cycle. From restoring older steam systems to designing new hydronic layouts for renovations, the focus has always been the same: understand how the system works before deciding what to change.

In many cases, systems that others recommend replacing can be improved, balanced, or repaired. When replacement is the right decision, it is done with careful planning and long term performance in mind.

A Different Approach to Service

Cochecho Plumbing and Hydronic Heating is built on personal service and long term relationships.

We believe in:

  • Repairing before replacing whenever possible

  • Explaining systems in clear, simple terms

Our goal is not just to complete a job. It is to ensure your home is comfortable, reliable, and understood.

  • "After multiple HVAC companies told us our furnace was beyond repair and needed replacing, Kevin stepped in and proved otherwise. Even though we were outside his service area, he made the trip, found the real issue, and fixed it with a single part. He saved us a huge expense and a lot of stress. We’re incredibly thankful."

  • "Kevin is the best! Quick response time, no nonsense service, and fixes things up very well. Not to mention, saved us a ton! Would recommend and call again for service as needed in the future!"

    K.C.

  • "Kevin is terrific. He was able to diagnose and fix the issues with my boiler, which were due to water quality. Three or four other plumbers tried to fix the problems, but didn't have the understanding of water quality that Kevin does. I highly recommend him for any plumbing project, large or small."
