I could never remember for sure when I changed my A/C furnace filter, so now I write the date I need to replace it on the filter with a permanent marker. Works great! No more trying to remember!

Remember to change your furnace's filter once every month. A dirty filter means your furnace has to work harder than normal and that uses much more energy. Also, if you have allergies, it can alleviate them getting out of control in the winter from the dust in the ductwork building up and being blown into the house.
Editor's Note: Check your furnace manufacturer's instructions for how often your filter needs to be changed. If you don't still have your manual, the manufacturer probably has a website, just type the manufacturer name and "furnace" into Google and you should find the right site.
Be certain your furnace is tuned up and replace filters frequently. These 2 simple precautions could save as much as 10% on your bill. (01/03/2005)
