Before the cold weather sets in, this is a good month to get into the habit of changing the furnace filter, if you have forced-air heat. As simple and as inexpensive as it is to change a furnace filter, many homeowners overlook this task. Believe it or not, furnace filters can get so clogged that the furnace can't push warm air into rooms. Clean filters can greatly cut down on energy consumption and save you money on your energy bills. To change the filter, simply draw it out of its slot next to the furnace.
Some filters needs to be replaced, while a few can be washed and reused.
A filter should be changed simply when needed - that could be monthly or every few months. Don't forget to check them in the summer when the central air conditioning system is running full speed. With a decent number of warm days left, October is a good month in which to reglaze a few of the windows on your home. Reglazing is a process in which you replace the putty that seals a bond between the window and the frame. That helps cut down on a lot of cold air infiltration during the cold winter months.
