What reviewers praise
Tech chose least-expensive fix first rather than upselling, per 1 reviewer: 'he did not choose the most expensive method to fix the issue, he started small and the fix worked.'
1 cited review
“he did not choose the most expensive method to fix the issue, he started small and the fix worked. This is like the old days were the folks showed up on time, you could trust them and they wanted your business for life, not just for a short term profit!”
Smooth quoting process with check-payment discount offered before work begins, noted in 1 review.

What reviewers report — the concerns
Other directories bury these. We think you should read them before you call. Every concern below comes from the reviews it cites.
Red flag
1-star review reports water heater installed in suboptimal configuration (flex connectors, unstable expansion tank) and no labor warranty offered on repair quote — specific workmanship concern on water heater jobs.
“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”
Water heater installed with flex-metal connectors failed after 2.5 years; company refused labor warranty and quoted $1,000+ for replacement — reviewer switched providers.

The evidence — in reviewers' own words
Positive
“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!”
