Do you remember your Grandma’s house, or maybe some other old person’s house? Remember how they had those cute long bean bag things that usually looked like animals with long, outstretched paws, lying down at the bottom of the doorways? Sometimes, they were standing on the window sill at the bottom of the window, as well? Well, hardly nobody has those draft busters anymore, because although they may look old fashioned, and I guess they kind of are, they really can help with the costs of running your heating and cooling system.
Because if your gas furnace or a/c has to regularly be working to heat and cool your air that continues to come in through the cracks and crevices around windows and doors, that gas or electric furnace or a/c has to run a lot more frequently.
The more often your a/c engages, the higher your utility bill goes up, of course. In fact, anything at all that you can do to help your heating and cooling system spend more time off, the better off you and your wallet will be. In my case, for example, I do not use the oven in the summer. The extra heat of the oven, combined with the natural heat outside, is going to be too much for my old a/c to deal with. If I ran the oven in summer, I swear my a/c would never shut off. So, I use the microwave or have a salad. I also have blackout curtains on my windows that I put up in the summer. When I close my drapes, the sunlight is completely not heating up my house. It’s like a shaded oasis in my house in the summer, and so my air conditioning doesn’t have to fight the rays of the sunlight streaming in the windows. And in the winter, I open those drapes and let the warmth of the sunlight help my heater heat the house.
