Cool air may be coming through the window a/c unit, but, if hot air is coming through, youre not going to have a really cool home. So make sure those seals are tight. If you can see light, you need brand-new seals. Also, make sure the window a/c unit is sitting in the window properly, as an odd angle could also permit air to escape into your home.
