“Just a quick note to let you know how pleased we are with the work your company has done for SDE. As I mentioned recently, the new HVAC system that your company installed for us last fall has performed beautifully. With a full year of heating and cooling behind us, we are more than satisfied with the Panasonic system. The individual controls on the new system make it possible to keep everyone comfortable. Not a small accomplishment in an older building like ours.

I also want to be sure to thank your crew for their professionalism and conscientiousness. The install could not have gone better. The project came in within budget and on time. We are pleased to work with your company and look forward to our continued partnership.”
