I want to thank you for an excellent training session yesterday. Never have I seen such an organized, well run systems training process. It was evident to me that your subs appreciated your professionalism, as much as we. You truly saw the necessity for the end user to understand the systems, and took the appropriate time and care. Many thanks!

I want to take this opportunity to thank you and your company for the professional, quality workmanship on the many Boiler Room replacement projects that your company has completed for the School District of Philadelphia. GEM Mechanical Services seems to be one of the best contractors that we have used.


I appreciate your hard work and dedication. It is not often that I can walk into a replacement boiler project and have little to say about what is wrong, but you seem to have this work down to a science. Thanks  again for your continued support!
