Money Saving Idea - Household

Replace central air conditioning filters every month during the summer to keep air flowing freely through the ducts and reduce strain on the unit. This simple step takes only a few minutes. Try choosing a particular time - for instance, the first Saturday of the month - so you don't forget.

Cost: About $11 for three filters.

Savings: 1% - 2% on cooling costs.

Bonus: New filters keep dust and mold from collecting on condenser coils, extending your AC's life. You also improve the air quality in your home by reducing the spread of allergens, allowing you to breathe easier.
