"We had two problems., a hot third floor in summer and a cold room above the garage in winter. We were shocked when Bill and his crew virtually eliminated any temperature differences in BOTH areas. We've never worked with such a detailed contractor and the savings are significant!"

Both of us noticed that the heating blower cycled less frequently than before even though the outside temperature was much colder. I didn't need to wear my fleece in the house to feel comfortable...I walk into all the bedrooms once or twice a day and I don't sense the temperature differential from room to room as we did before. Extend our appreciation to your crew for a job well done.

"Bill Smith spent over 2 hours with me when he came to do the estimate - it was like a home inspection....We had a major temperature difference between floors .... It was also very hot upstairs in summer. ... the radiant barrier is amazing...Overall, Bill Smith and crew at DRO were worth every penny. Just the estimate day alone was so informative - I've recommended him to a ton of people."
