I had these guys do a simple water heater install to replace my previous one that lasted at least 20 years and it lasted 2.5 years. They used flex metal inlet and outlet connectors (that I think is what failed) vs copper lines, put on a thermal expansion tank that wasn't in the most stable position and when I called them to replace it they wanted to charge me $1,000 plus more for shut off valves and thermal expansion tank replacement etc.... AND they would not give me ANY warranty on their labor. Well, I can tell you I went with Bernie's Plumbing, got a year labor warranty, got all the bells and whistles - copper inlet and outlet pipes, thermal expansion tank, 2 shut off valves and the best service ever for $850 total. How dare you mess with customers like that.

We've used CO Green a few times for our HVAC and a toilet issue. Everytime CO Green techs are great--kind, smart, and willing to explain the issue and fix, and Guy in particular is above and beyond with customer service. Y'all are the best!

Colorado Green Plumbing is an exceptional choice for all your plumbing needs. From the moment I called to get quotes, the entire process was incredibly smooth, swift, and spotless. Even before I made the payment, they offered me a discount for paying with a check, which was a delightful surprise. I thoroughly enjoyed working with this company and will definitely be returning for any future plumbing requirements!

Colorado Green was great to work with for out HVAC needs. They were available for appointments quickly after the call. They were courteous and thorough in their work.

We recently needed to replace our aging furnace and Colorado Green did an excellent job, both with diagnosing the issues and with helping us understand our options. It was more affordable than expected and the technician was very knowledgeable. They worked us in quickly, even though it was the holidays. Both my hubby and I highly recommend Colorado Green!
