Our Specialized Heating Solutions

We focus exclusively on high-efficiency boiler and radiant systems, ensuring you receive the most advanced and reliable solutions on the market.

Boiler Installation & Annual Service

The boiler is the heart of your hydronic system, and its performance depends on expert installation and care.

Air-to-Water Heat Pumps

Advanced air-to-water heat pumps provide an efficient, all-electric solution for heating your home’s water and powering your radiant system. These systems deliver dependable performance even in cold climates, making them a smart investment for long-term energy savings and year-round comfort.

A Seamless Process for Flawless Results

We’ve refined our process to deliver a smooth, transparent, and professional experience from the first call to the final walkthrough.

1. Expert Consultation & Planning

For new construction, we work directly with your builder, analyzing plans to design a perfectly-sized system. For existing homes, we begin with a thorough on-site diagnostic call to accurately identify issues and propose effective solutions.

2. Meticulous, Specialist Installation

Our founder’s deep industry knowledge guides every installation. We use state-of-the-art tools and techniques to ensure every component, from the boiler to the radiant tubing, is installed for optimal performance and longevity.

3. System Commissioning & Walkthrough

Once installation is complete, we don’t just leave. We perform a comprehensive system commissioning, including a combustion analysis for boilers, to fine-tune performance. We then walk you through your new system, ensuring you’re comfortable with its operation.

4. Proactive Annual Maintenance

We protect your investment with our dedicated annual service plans. This proactive approach, a service most competitors neglect, keeps your luxury system running at peak efficiency and prevents unexpected breakdowns.

Outstanding experience from quote to completion. David installed all the equipment for our radiant floor heat and hot water in our garage. From thoroughly explaining his quote, to an absolutely beautiful install (who knew mechanical could be a work of art) we were very pleased with the result. Highly recommend.

100% recommend I had David out to do a check-up on our Navient tankless water heater and it was a great experience. He was friendly, professional, and super informative. He not only serviced it, but he also explained what he was looking for, why, and what each result meant. When you're looking for someone to work on water system in your house, this is the kind of service you want.

Solid experience all around working with North Sound Boilers & Radiant. We purchased a home 18 month ago and have had boiler issues off and on. I had another highly reputable heating company out twice to try and sort out the issues but they weren’t able to get to the root of the problem. I contacted North Sound on a Sunday evening during one of our cold spells this winter because our boulder went down and my family and I didn’t have heat. David came over that evening. Amazing service! He got us back up and running and after some trial and error David was able to pin point my problem and come up with a solution. All along communicating very well and being a honest guy. I would absolutely recommend giving them a call for your heating needs.

Our 12-year old Triangle Tube boiler died recently and we contacted David at North Sound. Within 7 days he sent us an estimate and came to our Whidbey Island home to do the work. The work took about 7 hours on day1 and 5 hours on day2. He used an IBC boiler and pretty much replaced ~90% of the old boiler stem (pumps, tanks, lines, etc.) Dave seems to have the competence you would need with such a relatively complex system. Definitely not amateur hour with your gas/propane line, ignition and high temperatures and your water line all converging into this system. Potential for a down wind disaster. I did not shop around as we had used David for prior maintenance and his reviews are excellent. It definitely is not inexpensive - more than my used car cost. David came prepared with all the tools and parts he needed. No breaks. On time, cleaned as he goes. We will definitely use him again if needed. See pics.

Our boiler stopped working meaning we had no heat or hot water. David came out the next day and diagnosed the problem. Ours is an old boiler and the part was not available locally. He ordered the part through expedited overnight delivery and installed it Saturday morning. I recommend North Sound Boilers without hesitation. David is a skilled technician but more importantly a man of integrity.
