Our clients say it best...
“Arrived on time. Diagnosed and communicated exactly the service he would provide. Impressed with his professional knowledge, skill, work ethic sense of humor, and clear communication! Fair pricing. Will gladly recommend this company.”
Mimi K.Seattle“We've had on-going, very distressing issues with our heating/hot-water system for over 6 years and have been through 3 companies trying to get it figured out, always with the same results - lots of expensive bills but no real fix - until we found Carlson. The owner Mark was amazing, taking a very logical and scientific approach and even getting the Factory Rep. to come in to try to solve this difficult case.
Long story short, they solved the problem that no one else could, and we now have a reliable and efficient heating system again. Btw, their Techs are fabulous as well - clearly very well trained and highly skilled, and a pleasure to work with.”
Steve G.Seattle“This place was great. They serviced my tankless water heater after it was making super annoying knocking and clicking sounds. Was challenging to find someone to work on the Takagi tankless system. It’s running nice and silent now. And Marissa was super helpful with scheduling too.”
