"that needed to be performed, as well as a cost and time estimate to install these improvements. I appreciated being able to ask questions and have a positive and informed discussion about the issues. Dan is a very pleasant and knowledgeable "gentleman" who works very hard at explaining the tasks that needed to be performed. Dan is the one who made me believe in the Mark Group and it's ability to make these changes translate into energy savings.
When the work was scheduled to be performed, the installers were knowledgeable professionals, who showed up on time and worked long hours to get the work complete within the two date estimate.
The work was done with respect for my property and without undue interruptions. The installers were also very pleasant and informative.
Dave Condin was the final person who came to do quality control. He is an amazing and talented person. He is fun to talk with and seems to be the ultimate problem solver.
A week after the installation we are now facing a heat wave, and I can already see the benefits of this program. My house does not heat up because of the attic. The air conditioning runs less frequently, and the house seem far more comfortable.
The best part is that PEPCO agrees to a rebate off the cost of the installation. This makes the process and unbelievable bargain.
