We had problems in the attic with the home we recently bought. Being in the Mechanical trade for 40 years I knew the value that a tight duct system, insulation, and ventilation could have on our home. I started getting priceing and recomendations. Mr Rivera came to my home very promptly and worked an estimate with his recomendations and after review the other quotes we went with EHS. His crews came to our home very professional and courteous. They performed their task in a very prompt manor. The difference the work made has been very significant and noticeable. We are looking forward to seeing our next electric bill. This work was completed on schedule May 11,2012.
