Cooled air has to travel through your attic before it reaches your bedrooms, and that's where a lot of it disappears. Loose connections, gaps at the joints, and crushed flex duct all let conditioned air escape into unconditioned space instead of your living room. Your system ends up cooling the attic more than your house, and the energy bill reflects it. Rooms at the end of the ductwork are usually the ones that feel warmest, even with the thermostat set the same as everywhere else. Sealing those leaks is a quick fix compared to what you lose every month it goes unaddressed. If certain rooms never seem to cool down, this is often why.
