Heating and cooling many times will eat away at your monthly budget. To keep utility expenses down, consider doing things around your house that will keep cool or hot air from escaping. One very important way to do that is to make sure that your attic is well insulated. In the winter months, hot air rises and you will lose heat through a badly insulated attic. In the summer months, the attic gets very hot and that heat will transfer to the rest of your house forcing your air conditioner to work even harder.
Insulating the attic yourself is rather simple and easy and can be done for a few hundred dollars depending on the insulation you choose. I personally like the GreenFiber because it is eco-friendly. It can be found either at Home Depot or Lowes. If you buy 20 bags or more, they will rent you the sprayer for free. Also, remember, before you insulate, to make sure to seal or air leakages in the attic such as areas around recessed lights, vents, etc. All of these little things are inexpensive and will keep
your heating and cooling bills low.
