Dear Gary,

I just wanted to say thank you for installing our new Quantum CO System.

The existing Macurco System we had in our building was not operating properly and as soon as you replaced it with the Quantum CO System everything works great. Using the existing conduit / wiring saved us time and money and is very much appreciated.

I also want to thank you for going the extra mile and paying for some extra work to allow our EMS to interface properly. It was not your responsibility to help us out when we got a surprise bill from our EMS contractor, so it showed me that you really are about our needs.

We also really appreciate that your system does not need any calibration or the associated costs like our other system needed. this is a relief to us since we are already busy enough with many other things in this building.

We look forward to working with you in the future and we are happy to recommend your system to others needing a top-notch installation.

Thank you
