As the following comments reflect, we will be there whenever you need us.


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.

Tom Geissler

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!!!!


Josh Grange, Field Operations Manager, MAX Construction

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.


Michael Musso, TIAA-CREF

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

Rob and Cliff,

I wanted to personally thank you for sending Paul and Cody to evaluate [our] HVAC systems. Paul and Cody are extremely knowledgeable, competent, and embody the best in customer service. I was so impressed by their helpful approach in evaluating the systems and explaining the internal problems. They both took the time to help me clearly understand potential underlying problems. Congratulations on have the best in class technicians. They are a wonderful example of why Ducts Unlimited is the top-tier provider of mechanical systems HVAC expertise. I will be recommending Ducts Unlimited to all my commercial clients.

Best regards,

Andrew Coit, Tower Commercial


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

Check out our complete list to hear more from our satisfied customers.


Just a quick email about SNC. I wanted to say how great the install was at the SNC Hanger 13. Oso did a wonderful job with the trunk lines, the flex, sealing the ducts. It was straight, clean and looked great. He was very responsive to questions and always had an answer when asked.


Mike, Sand Construction of Colorado


I wanted to let you know how much I appreciate the effort you and Oso put in on the CHI project. It was due to the hard work of both of you that helped us finish the project. We really think that Oso went above and beyond at the end of the project to help get the final HVAC with the building department. Thanks for your help!

Dennis "Mike", Kiewit Building Group

I just wanted to let you know that Arturo and Leo did an awesome job for me. This was my second job with you and these tow gave me excellent customer service.

Bret, Mountain States Construction


Just wanted to say thanks to you and your crew on the MEP job. I enjoyed working with Mike in the field and he did a very professional job. Fernando also stepped in and got him all the materials he needed on time. So thanks to you and your staff.

John Johanns, Alcorn Construction Inc.

Cliff and Rob,

I would like to thank you for sending Dan and Gerald out to the Lockton projects. Their performance on a complicated set of projects was exemplary and I would recommend them as an outstanding one two punch to our management team any day. They were able to overcome several challenges and were paramount to the success of my projects.

Darrin C. Hawkins, i2 Construction


I wanted to shoot a quick email to address the experience I had with your on call service tech this past weekend. I only know him as Paul but what a class act. His dinner out with his family was interrupted by us at 6:30 Saturday evening and not only did he react immediately, but he did so with complete professionalism and courtesy. All I can say is OUTSTANDING and know that he represented your company in a manner of which you should be very proud.

Mark Stratton, Coda Construction Group

Cliff and Rob,

I wanted to let you know that both Fernando and Eric Garcia did an excellent job on the Suite 2540 project. We planned on having our inspection on Friday 2/17/2012 and due to the City of Denver having a furlough day we were forced to move up our inspection date. Eric and his helper were still able to make the earlier inspection and Fernando was able to provide additional man power to ensure that we passed our inspections. Ducts did a great job and the property management is extremely pleased as well. I look forward to working on future projects with Ducts Unlimited.

Ben Berry, Superintendent, Max Construction

Mr. Leishman,

I do not believe that any firm working on the AIA Colorado project profited monetarily, (At least not those who volunteered their resources). However, recognition of a job well done is warranted where applicable, and I belive it is applicable on this project.

Until now, I personally was not aware of your Ducts Unlimited existence. However, from here on out I will keep in mind as one to recommend should the opportunity present itself.

My compliments to your team.

Steven E. Inlow, BCER Engineering


Thanks for all the years of service and keeping us up and running. I never had anything to worry about when Ducts was on the job.

Jack, Health Dialog (Denver Site)

Dear Rob,

In a recent job close out meeting we were told by Greg Gruno, our Superintendent, that your company and on-site crew preformed their job above and beyond expectations.

As you may or may not be aware, about 90% of our projects come through repeat clients and referrals. The only way we can maintain this ratio is by consistently delivering a superior product for each of our clients. You continue to be a valuable part of our team and your contributions allow Mendel & Company to pursue our goal of "Building Relationships."

We would like to take this opportunity to say "Thank You" and let you know how much your company's work ethic and dedication are appreciated.


Nathan Mendel


I wanted to take a minute to advise you of the work efforts and hard work that Ducts Unlimited did for me on the WSMT project. Your lead guy Eric, was awesome at always checking with me from day to day on my needs and path of their install. As you know the Modulines came in on many different shipments. Once we had a lot here Fernando Gomez made sure he put more men on the project for Eric. They were able to do the install of the Modulines and all the piping along with the controls that has allowed me to knock off a week from our schedule.

It is very clear we have Ducts Unlimited as a Team Player on our projects. Please Pass this on to Estimating and to all the other office managers.

Congrats to Eric and Fernando and their field team for making this happen.


Mike Thaker, Field Supervisor, i2 Construction

Thanks for your help in locating the mounting kit for the LAN room diffuser. Your efforts certainly saved many hours of searching later on. Also, please pass my thanks to Joel and Ryan for all their hard work as well, particularly for installing the burglar bars and inspection doors. They worked really hard in a difficult place to get the job done.

Thank you,

Paul Gibson, Foreman, Fransen-Pittman

I wanted to let you know that your communication has been great with all the projects at Denver Place. We have not missed a beat and you have been on top of every concern/change order. The 4th floor has been especially difficult because of the starts and stops, but again you have accommodated Max Construction and LBA Realty. Also I appreciate having Arturo as a foreman. He has always been polite, he is thorough, and he makes sure that his job sites are clean every night. Ducts Unlimited is the cleanest contractor that I have right now and I can not remember the last time I had to ask them to clean up after themselves.

Thanks and I look forward to working with your team in the future.

Jeremy McKinnon, Superintendent, Max Construction

I wanted to write and personally thank you for all of your hard work at the Duffy Crane project. I understand It was challenging and difficult project and I appreciate the quick response immediate attention to the issues we had. It’s hard to find great sub contractors like Ducts Unlimited and I wanted you to know your efforts have not gone unnoticed.


You ALWAYS do the best you can. I could do the rest of my HVAC with you. I wish the other contractors I work with would be so good.

Big G, Mendal and Company

...thank you Ducts Unlimited for what you have done at the US BANK OPERATIONS CENTER. Your field foremen Richard and Jerry did a wonderful job for us, as well as the crew that stayed late working on the CRAC Units this week. Hope to work with you again in the future.

Wade Caron, Superintendent, JE DUNN

Allan Fries, President, i2 Construction

Excellent quality & price with a fast turn-around. A pleasure to do business with.

Jesse Trout, Owner, McCormick Mechanical

We enjoy our working relationship with your firm as well. At the moment bidding is a very tough venture. I know we are asking for big sacrifices on the jobs we go after. Rest assured your willingness to support our efforts does not go unnoticed. In good times we let the bids fall as they fall without pushing our base of subcontractors to the extent that is required by such a tough economy. We appreciate your willingness to do all that you can in an effort that we may all stay gainfully employed.

Thanks again for all the good times, friendships and your business professionalism. I am sure we will all work together for many years to come.

Alex, Max Construction Inc

Rick displays a genuine desire to get the project completed with quality and efficiency. He shows that he cares about the way that his crew handles themselves while on site. I have been privileged to have a competent person such as him on my project, and look forward to working with him on future build-outs.

Ryan Nieto continues to do an exceptional job for me from the administrative end. Which has been proven over the last 1.5 years of service at Lockheed.

In general I have been impressed by the way that Ducts Unlimited has been committed, and shown, the commitment to be a premiere HVAC company.

Kudos to all involved at Lockheed Martin Corp.

Thanks again,

Chad Kirkland, Pinkard Construction Company
