"The work was performed to my satisfaction. The Sam and the crew arrived on time and explained what was going to happen. The crew prepared the house to minimize any dust and went to work. The job was completed in two days. There were a couple of issues during the job, which were addressed in a timely manner. Overall, I am very happy with the work and would recommend American Attics."

"Juan and his crew were amazing, they did everything as asked. I wasn't exactly an easy customer as I had a custom layout for my airducts and they knocked it out perfectly within a day when other estimates said 2-3 days and for a fraction of the cost. Started out as a DIY, so I had most of the material and they made it work."

"Excellent experience with this company. They lent us a portable air conditioner while we waited for our new air conditioner to be installed. They helped us with financing the new system. All the service employees were helpful, friendly, and knowledgeable. They even came out to help us after the office was closed. I fully recommend their company."

"We hired Guardian to install our security system at our Washington, DC, business. The service and quality of the work was horrible. We had cameras and an alarm system installed; it was a relatively large system. They outsource most of the work to various vendors. They could not manage their vendors; what was supposed to take a week took two months. The sales rep did not return calls, and you could never get anyone in management on the phone. Random people would show up at unannounced times. The few things that an actual Guardian employee did were they made a huge mess of our newly remodeled office and were rude to our staff. We have offices in five markets across the US and have high security at each; we have never had such a poor experience."
