Best Air Filtration in Portland OR

Jeff went beyond the extra mile in helping us solve our sewer issues. Scheduling and communication was quick and easy. We will definitely continue to use 3 Mountains for our plumbing work.

This is the second time Justin has been out to my home..What a pleasure! He is super efficient and helpful. He explained everything and made sure I didn't need anything else. He is very professional and pleasure to talk to. I will make sure I ask for him again! Thank you again Justin for the great work!!!

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.

Great service and value. Best price I could find for a tankless water heater install.

Terrible experience. Find another company.
