Historical Restoration of gravity hot water and steam heat in Seattle

This is more than just a slogan, it highlights one of the real strengths of Carlson Mechanical.  We have the skill, knowledge and experience to work on the beautiful Seattle homes that were built from the late 19th into the early 20th centuries

Whether you want us to repair the home’s original steam or hot water system or you’re looking to upgrade your home’s heating system, our technicians are able to do the work. Plus, we have the professionalism to treat you and your home with the care and respect you deserve.

Seattle's older homes are our specialtySteam Radiant Heat

The original gravity hot water or steam heating systems still operating in many of these homes require true craftsmen to maintain and service them; craftsmen that you will find at Carlson Mechanical. 

When the time comes to upgrade to a new boiler or add new heating during a home remodel, these same craftsmen will install the new equipment in a manner that is guaranteed to work and keeps with the character and quality of the home.

Whether it is the former British Consulate, the Rhodes Mansion, or your beautiful Queen Anne 'Turn of the Century' Victorian, we will complete the project to your satisfaction.

Thank you so much for your recent fine work coordinating the removal of our old oil-fired boiler and then installing a new Viessmann gas-fired boiler. Thanks for delivering so well on the promises you made during our initial conversations, for being such a pleasure to work with during the project and for ironing out wrinkles as the new system has begun to heat our home.

The Truck

I just wanted to thank you for all the outstanding service during the last year.  It was a big step for us in buying our new “old house.”  We had a lot of concerns about converting from oil to gas and also moving out the old unit and moving the new one closer to the wall.  Everything went as planned and we had a toasty winter, hassle free.  Cannot thank you enough!

Rhodes Mansion Seattle

Rhodes Mansion in Seattle

Our challenge was to remove the old 1930’s boiler and replace it with a modern, efficient gas-fired boiler while maintaining the character and appearance of a boiler from the 30’s.

Attention to detail is key

As you can imagine, this required additional labor, as all the black steel piping had to be screwed together by hand since copper was not used for heating pipes in the 30’s.

The owner was appreciative of our attention to detail, right down to the push-button switches for the pumps.
