Expert Boiler Service for Seacoast New Hampshire Homes

If your home is heated by a boiler, you need someone who understands how these systems truly work.

Many New England homes rely on steam or hot water boilers for heat. When something goes wrong, the issue is often more complex than a simple part replacement. Proper diagnosis matters.

At Cochecho Plumbing and Hydronic Heating, we specialize in evaluating, repairing, and when necessary replacing residential boiler systems throughout Dover and the Seacoast region.

Boiler Repair

Before You Replace, Let’s Evaluate

Boilers are often replaced when they could have been repaired or improved.

We frequently work on systems that:

  • Heat unevenly or leave rooms cold

  • Make banging or hissing noises

  • Short cycle or run constantly

  • Have circulation or venting issues

  • Were previously “fixed” but never truly corrected

Our first step is always a careful evaluation. Many problems can be resolved by balancing the system, improving venting, replacing controls, or correcting installation issues.

Our goal is to restore safe, reliable heat whenever possible.

Boiler Replacement

When Replacement Is the Right Choice

There are times when replacement makes sense. Age, efficiency, safety concerns, or major component failure can make a new boiler the better long term solution.

When that time comes, we provide clear options and explain:

  • What type of boiler fits your home

  • Efficiency differences

  • Fuel options including gas and oil

  • How the new system will integrate with your existing piping and radiation

We do not install one size fits all systems. Every home is different, and the installation should reflect that.

Most importantly, we remain available after installation to ensure your system performs the way it should.

Boilers vs Furnaces

Many homeowners refer to any heating equipment as a “furnace.” In reality, furnaces heat air. Boilers heat water or create steam that circulates through radiators, baseboards, or radiant floors.

If you are not sure what type of system you have, we can help you understand it clearly and simply.

  • "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."
