"We had a great experience with Discount Energy Services. They insulated our entire attic and crawl space, and from start to finish they were professional, responsive, and easy to work with. The turnaround time was impressively quick, the quality of the work was excellent, and we felt the value was very good for the scope of the project. The team was efficient, knowledgeable, and clearly took pride in doing the job well. We really appreciated how smoothly the whole process went and would gladly recommend Discount Energy Services to anyone looking for high-quality insulation work."

"Great! Job was complete .... removal of existing 50+ year old insulation, air sealing attic, baffle installation, installed 18 inches new fiberglass blown insulation, and new whole-house fan. Job started and completed as proposed. Crew on-time, quietly performed their work, and left spaces clean when done. Definitely worth the cost as noticeable improvement in second floor temperature and humidity readings."

"My roof issues stem from solar panel installation. The installers damaged several shingles, including roof vent shingles, and upon my complaint did an awful job trying to patch it. I called American Home Contractors for a survey of the damage, and they sent out Isiah, who did a phenomenal job. He wrote up a very excellent report detail all of the damage and repairs needed to bring my roof back to its original condition. He supplied me with clear pictures of everything, and took time to explain everything to me so that I could understand the estimate. I feel much better now knowing exactly what damage was done to my roof, and that I can rely on Isiah and American Home Contractors to restore my roof back to its original condition. Based on this experience, I would strongly recommend AHC for your next roof repair."

"There was a problem initially with the radiant barrier installation - the first crew of two were installing 30" wide rolls lengthwise along the roof end to end instead of from ridge to eave as the manufacturer recommends and made a couple of other minor mistakes which were easily corrected. After talking to the manufacturer, the sales rep offered to take out what had been installed and re-install according to spec or continue as already done with sealing of all seams and a discount on the job. Done this way, the foil would not have the insulation properties per spec but would provide the radiant barrier I desired. I chose the letter option and the barrier work was continued by another crew on the 2nd day. On the 3rd day the crew finished up with the barrier then blew in the installation.
With the exception of the initial problem, the work was done neatly and professionally by courteous workmen who cleaned up completely after the job was done.

"The gentleman who conducted the audit was thorough and professional. The audit itself was informative. I went ahead and bought the service they recommended during the audit which was increasing the insulation in my attic. I was more than happy with the service. They forgot something during the installation of the insulation but the manager was prompt in rectifying the situation."
