Best System Upgrades in Portland OR

Fat and efficient.

Green Box Mechanical repaired my electrical panel for my air conditioner. They were efficient and got the job done. They also, did the annual maintenance on my hvac system. They are a great company to work with.

Great service, quick dispatch time. Mike in dispatch was great at working us in. Recently had a large service call and was happy w/ their service and total cost.

We refer these guys a lot, so do insurance companies

First, the receptionist was 100% upfront about the hourly rate and any incremental costs. They were able to book us first thing in the morning. Nick showed up at 7:55AM for our 8:00AM appointment. He was professional, wore a mask, and offered to wear shoe covers as well. He was efficient and didn't waste time and explained everything he was doing as he proceeded. He cleaned up before he left. My wife and I were very pleased with the work and professionalism and will absolutely be using this company for any future plumbing issues. highly recommend.

They figured out the problem with our water fast and efficientjad it repaired in a couple of hours. Thanks Andrew!
Their superintend worked with us on the billing to make work within our budget as well. Thanks Bob!
