HERS Rater

We have worked with PSD in the FirstEnergy New Homes program in Pennsylvania for the past couple of years. It is so refreshing to work with an organization that is easy to work with, supportive and quick to respond to any questions we have. PSD’s process of registering and applying for rebates is such an easy process. Thank you for making this so user friendly!

Energy Contractor

I love to work with PSD on above code and energy efficiency programs.  Their software is easy to understand and convenient to use.  There technical help is both knowledgeable and timely, I just send them an email and I usually hear back within an hour.  They make it easy for me to help my customers maximize their participation in the programs.

HERS Rater

I just wanted to thank you for the feedback, and for the quality of the QA report. Because of the many rebate programs in which we operate, we get a lot of QA done by the implementers of utility funded programs. This is by far the most professional QA report I have received from an incentive program.
