Best Annual Furnace Maintenance in Portland OR

Ryan and Zach were punctual, polite, and extremely efficient in getting me a very reasonable estimate and then getting the job done. I’m very happy with the service I received. I would definitely recommend this company and will use them again in the future as needed.

We used Greenbox to perform early season maintenance on our central A/C system. Technician Nick did a very thorough job and went above and beyond to examine and ensure our system was operating in fine fashion. Very pleased with this maintenance work. Will use Greenbox in the future. Thank you.
