I was at a home where the owner was struggling to keep their upstairs cool, even with the AC running nonstop. I identified a major source of the problem: their attic pull-down stairs were allowing a huge amount of heat to transfer from the attic into the hallway. I solved this efficiency issue by installing a specialized, insulated attic tent. This device creates an airtight seal over the attic opening, effectively stopping the heat gain and making it much easier for their AC to keep the home comfortable.
