I've worked with DEEM in several aspects for several years now. Their service techs, installers, engineers and electricians are what makes the company what it is. John Walters, Steve Cool, Darin Ruling and Dave Hettwer are some of the greatest guys out there to work with. They go above and beyond their required job responsibilities to help you and your company out in ANY situation. You won't be left hung out to dry in a downtime/breakdown situation with these guys. DEEM is not just any typical contractor in my opinion. I have over 16 years of dealing with DEEM to back my statements above.

I recommend Deem, LLC train their employees how to drive. This morning one of their drivers was hanging out in the left lane on I-70 westbound. He almost caused an accident when he purposely slammed on his. brakes to get me off his tail-- dude move over, it's the law. He knew what he did because as soon as he saw me take the attached picture he moved over and glared at me.

I recently took an new position at a facility as the maintenance manager and step into some tricky situations. The technicians at Deem have gone above and beyond to assist with the situations I encountered. Couldn't be happier with the service.

I've delivered here twice now. Both times with a single a/c unit. They only have one person unloading and I guess loading trucks. It takes forever to get 1 a/c unit unloaded.

They quoted me 1600 for a plumbing job 4 days ago. It was a father and son team. The son has posted on his Facebook page that he works for Deem LLC. I put a post up on Facebook saying I needed help with my plumbing so my kids could come home. He told me him and his dad could do the job. They showed up in a Deem plumbing van. I'm thinking great I'm in good hands. They took 450 dollars for materials 4 days ago.
I haven't seen them since. He told me he was here one night when I was at work and cut all the pipes out. I see no evidence of that though. He told me all day yesterday he would be here. Nope. He said he would be here at 8 this morning. I still haven't seen him. I'm getting ready to call Deem and see if I need to sue. The name of the father and son team was Alan and Bryce Troxell
