    The draft test is always the way to go! I replaced my windows after feeling a noticeable difference in coolness in my bedroom. The rest of the house was nice and cozy, but then my bedroom would be really cold and would get colder as the temperatures outside would drop. Not to mention, when it was hot outside, my bedroom was hotter! Anybody that feels a draft should check their windows first thing. It is almost always the cause for a temperature drop. And the thing is, you are losing money every minute you don’t do something about it. The draft test is a sure thing. It only takes a couple of seconds to check and will make all the difference in the world.
