Just had the Pacco Window films installed today, and the heat was noticeably reduced quite immediately! I chose Pacco because of the high service level from Chris and the quality standards attained by the company for their solar films. He is very knowledgeable about the product, and took the time to explain and address the many questions I had. He is always prompt and this gave me the added confidence. We had a team of two to install the films , which took 6 hours . They worked quickly, quietly and neatly. Chris also came to provide the initial supervision. I am overall very happy with Pacco. Thanks to Chris and his team!
