At home, your best spending is to improve your energy efficiency. Unless you seal up the drafts in your home, you are letting money blow right out the window. Heating and cooling your home account for nearly 50 percent of a typical household utility bill.

Now is the perfect time to take on two very simple projects that will practically pay for themselves in a few short weeks.

We've all heard about the benefits of installing extra insulation and weather stripping around doors and windows, but there are two additional leaky culprits that you should know about. Both allow heat to escape from your home in the winter. Fortunately, both are not expensive to fix.

Warm air rises. If you have a fireplace, it's likely rising right up and out of your home all winter long. Unfortunately, there are very few fireplace flues that offer an airtight seal. Also, many times we forget to close the flue between fires.

There is a simple solution: an inflatable balloon that fits just under the flue, sealing off leaks. It's called a fireplace plug or chimney balloon — and you can install one in less than five minutes.For an investment of roughly $60, you can seal up one of the biggest sources of heat loss in your home during the winter.

The second place to save some serious money is by insulating your attic entryway. Whether you have a pull-down stairway or a vertical door, attic entryways are rarely insulated. This provides the perfect escape route for air you've paid to heat. Conversely, during the summer it's also a source of hot air leaking into your air-conditioned home.

Doing your part to seal up the sneaky leaks in your home is a great return on investment. For about $100 and 30 minutes, you can instantly improve the energy efficiency of your home and lower your monthly heating and cooling costs. This is one smart investment that will yield an instant and long-term return.
