To Whom It May Concern:

Dear Sir or Madam:

It is my distinct pleasure to write this letter of recommendation for Entis Mechanical Services. I have worked with Entis Mechanical Services for just over a year. It is my opinion that we have saved several thousand dollars during this past year by working with a company who is professional, proactive and honest to provide our HVAC, Mechanical services. Entis Mechanical has proven to be knowledgeable enough to work with some of our older and larger systems and also willing and capable to install new smaller systems for us as needed. They have been the "ONE CALL TO FIX IT ALL" HVAC vendor who we can count on to be timely and honest while remaining competitively priced. I am pleased to recommend Entis Mechanical and I have evry confidence that they will be able to fit the needs of any company or individual with HVAC, Mechanical needs.

Sincerely

To Whom It May Concern:

Entis Mechanical Services recently provided construction services at the Waller facility of FlowChem, Ltd. The project consisted of unique design and installation of pneumatic conveying equipment that operates under cryogenic conditions. The installation timetable was extremely tight and there was no room for delays.

Entis was able to secure and fabricate all of the necessary parts and completed the project within the allotted time. An Entis supervisor was on-site at all times to make sure the deadlines were met.

This is not the first project that Entis has helped us with. All of the previous projects were also completed in a timely fashion, just as Entis had promised. I have every confidence that you will be satisfied with the level of attention and professionalism that Entis delivers.

Sincerely

Flowchem, Ltd.

To Whom It May Concern:

I must say what a first class operation Entis Mechanical Services has been to work with. The people there are kind and courteous. More importantly they do what they say they are going to do. Entis and their staff have gone to great lengths to ensure that our expectations are met each and every time we call on them. They are committed to getting it right, even if that means fixing someone else's mess. From service to new equipment, the folks over at Entis Mechanical Services have done an outstanding job taking care of Schulte Building Systems needs over the past year. Keep up the good work!

Sincerely
