Historical Restorations are our Specialty

Carlson Mechanical is one of the few companies in the Seattle area with the skill and experience to work on the turn-of-the-century equipment in historic homes.  The steam or hot water boilers in these homes require a true craftsman to service and maintain them. 


Whether you need equipment repaired or a whole house renovation, Carlson Mechanical can handle the job. 

Our Mission

Combining new technology with the skill of craftsmen, we provide our customers with efficient, reliable and comfortable heating systems.


Let the skilled craftsmen of Carlson Mechanical work with you to create an elegant system designed to last a lifetime.

Your Comfort Is Our Goal

Hydronic heating (most commonly known as radiant heat) provides the best comfort system in the world with its even, natural heat. 


Radiant heat is one of the most energy efficient ways to heat our home and since you are using hot water or steam for your heat source, the air in your home is cleaner. 


That’s great news for those who suffer from allergies or asthma.
