"I would like to extend my sincere thanks to JC and the whole team at Greenbox Mechanical.  Our AC went out on a Friday before one of the hottest weekends of the summer.  We called JC and he had someone onsite Saturday morning at 10 am.  The tech that came out was efficient, personable and did a fantastic job.  In a little less than an hour our AC was up and running and the following day I received a phone call following up to make sure everything was good to go. I would highly recommend Greenbox Mechanical for all of your HVAC needs!"

"As our summers are getting hotter and with the increase in forest fire smoke in the Portland Metro area over the last few years, my wife and I are finally considering installing air conditioning in our home. We have an older heating system into which we weren't sure how we were going to incorporate an AC unit. I discussed my issue with JC and he assured me that we would have options. I scheduled a meeting with Green Box to come out to our house and one of their service techs, Michael came by. His communication prior to our meeting was prompt and professional and he even called me the day of he appointment that he could come early if I was available. Michael assessed our system and thoroughly ran me through the entire installation process, which included an AC unit only option and a whole system replacement option (new furnace and AC). Although we haven't committed to an installation yet, based on the service we have received so far from Green Box, I am confident that we will be happy with the end result. Thanks JC!"
