If you think you are done using the air conditioner, it is a good idea to turn off its breaker or fuse. If you don’t, the small amount of heat generated in the air conditioner when it’s off makes a perfect home for mice in the winter. Also, now is a good time to install the cover on the A/C. Remember, do not wrap it in plastic. Use a quality custom cover that breathes or even just a piece of plywood on top to help keep out the snow and leaves.
Change the filter in the furnace if it is a throw-away style. If it is a washable style, simply hose it off or use a mild detergent if it has greasy dust.
If you have a humidifier, some styles have a damper in them that should be reset to the winter position. Humidifiers also require cleaning once a year and the replacement of its pad or water panel. If it has a manual humidity control, turn it on and set it for 35 percent humidity.
Make sure the area around the furnace is uncongested and nothing is leaning against the furnace or restricting airflow to it.
If you have an electronic or programmable thermostat, change its batteries and don’t forget the batteries in the smoke or CO detector.
If your furnace has plastic exhaust pipes that exit through the side of the house, make sure they are clear of vegetation and that wasps have not built a nest in them over the summer.
It is highly recommended you have your system professionally serviced at least once per year. This allows the furnace to run at peak efficiency and will ensure it is operating safely. It doesn’t matter when it is inspected, just have it done once a year.
Lastly, go ahead and turn the furnace on now, to make sure it works before you really need it.
