Jeremy Romero and Todd Kingsley did a wonderful job and were a pleasure to work with, this was a challenging job to do with the owner’s changes.

Then were very professional and were very efficient doing their work I appreciate all their efforts.

Please tell them I am very pleased to have had them on my job.

Jeff Chavez, Superintendent, Foothills Builders

Happy Holiday, Fernando,

We just concluded our final phase rough HVAC inspection here at Zillow Group and are nearing the end of the tactfully difficult and challenging project. I wanted to send a "Thank You" to you for always having great techs on site that have made this difficult phased project for me and Max Construction Inc. much more tolerable from a logistical point of view and their service and attitude and professionalism has been above reproach and grealty appreciated. I also have had the same great service and attentive care with Osso and Reciardo on my projects this year, Colorado State Bankd and Trust, Berkely Insurance and Caserus Oil and Gas...

Robert Halterman, Misha Campbell, Osso Lopez and Ricardo Gomez have done a wonderful job servicing Max Construction Inc. on this project of close to four months and I wnated to take a moment of your busy day to give you some good feedback about your crews. Besides being professional, knowledgeable, and Dedicated to their craft, they are always helpful, supportive and eager to make our job as superintendent just that more easy by taking charge of the HVAC part of the responsibility and following through with great workmanship to the very end. I am not accustom to sending accolades to the leadership of other service companies, however, if I were you, I would be proud to have them as team members doing the great work that they do on a consistent bases.

PS. Robert Ulrich has also been instrumental with scheduling and supplying them with leadership and guidance along the way on all the projects and should be commended for his behind the scenes' contribution also. Then are all a great team and I look forward to working with them in the future......

Merry Christmas.....


Tim Powers, Superintendent, Max Construction, Inc.

I just wanted to take a minute to tell you that Jeff and his crew did an outstanding job at 1670 Broadway. The Tenant Demising project was anything but straight forward and thanks to his communication skills and positive attitude we got things done in a timely and accurate manner. He’s a great craftsman and a great leader. Treat him well and I look forward to having him on my next job.

As you know our business is very challenging and we are only as good as our weakest Subcontractor, I wanted to take quick minute to let you know I appreciate your Team's efforts on the completion of Columbine on Main.

The project was fraught with many challenges and it was due to the dedication and hard work of your staff tath we finally completed the Project.

A special thanks to your field staff of Tony Anderson, Mikey, Rob Ulrich & Rob and on the office side of Fernando and Jeff Mozzogotte!

Dan Rondinelli


I would like to take this time to let you know how your crews in the field did for us at the new Penske job that we just finished.

Dan did an outstanding job of getting done when he said he would be done and had very few items on call back and punch list. I look forward to working with Dan again on future jobs.

Travis was a big help on getting the controls all worked out for the boilers and fans. Good job Travis.

Steve Moser, Project Superintendent, W · E · O'NEIL


I just want to send a note about the outstanding, remarkable work that Joe [and his co-worker] did on Saturday. They came in to work on Saturday, banged out that project, and did a heck of a job. They are great workers, very professional, and know what they're doing. Ducts Unlimited is an extremely experienced and professional company.

Thank you,

Enrique Trujillo, Brownstein Hyatt Farber Schreck, LLP


I ran Vitol this week and your field guy and his helper were great to work with.

They came ready to work, with a positive attitude every day. I asked for your inspection to take place on Friday and today the job was finaled out.

Robert is self-sufficient on the job and gave me updates on his progress via phone calls. This is relatively unheard of with field guys for all trades.

I would like to have Robert on more MAX jobs!!!!

Brad & Fernando,

The UPS duct work at TIAA is complete and we are very happy with the end product as well as the pride that Gerald had in his work.

To whom it may concern,

Oso was the installer and foreman on our tenant finish project, Triangle Petroleum. I just wanted to take a minute to say how well Oso performed on the project from start to finish. He was courteous, and dealt with issues in an effective and efficient manner.


Ben Brandow, Boots Construction Company


I am writing to express my appreciation of the team effort given by Ducts Unlimited regarding the Encana 13th Floor tenant improvement project. Your office did great in meeting my needs and releasing material and work so that I could meet my aggressive schedule. Your onsite team did a fantastic job coordinating with myself and the other trades and exceeding expectations regarding schedules. The quality was top notch and their willingness to protect other work and materials was much appreciated.

I look forward to working with Ducts Unlimited again in the near future.

Phil Blackford, Provident Construction


I just wanted to say thank you for posting Matt to the USI project: he did a great job. The building engineers were very happy with this abilities and knowledge. The Greenwood Village Building inspectors were also both very impressed.

Matt is always welcome on any of my projects.


Jim Davidson, Project Superintendent

I wanted to thank you for your service department dropping what you were doing to assist Carol and myself on executing the inspection of the South Park Building. I know you were very busy and that I can always count on you guys coming through for me. It is my understanding that Carol and her client are very pleased with your performance and asked me to pass it along to you.

Don, Gallup-Craig Construction


I wanted to say that I will be requesting Matt for all my jobs with Ducts. I had Matt and Steve for the majority of the time on the RBC project and was extremely happy with both of them. They both have a "can do attitude" and communicated great with each other and with me. They look ahead to what is coming up and deliver what they communicate. Ducts is lucky to have guys like this in the company.

Jarrod, HITT Contracting


Usually my emails are to ask for something or address a problem that the field can't solve. This email is to congratulate you on a job WELL DONE!

Joe was my on-site foreman. He handled himself with professionalism and a genuine concern for our project. We always try to have the best people on our projects, but Joe stands out as a true tradesman. When we had a problem in the ceiling (which we always do) Joe made competent suggestions that the Mechanical Engineer agreed with. The Building Engineer and Manager even noticed Joe's quality of work and mentioned his professionalism to me as well.

Just wanted to say thank you and great job!

Best regards,

Richard, Max Construction
