Replace Furnace Filters
Replace the furnace filter monthly to ensure efficiency and keep dust particles from penetrating the clean, heated air. Inspect your furnace for leaks and test for carbon monoxide. If your furnace is older, cracks can form and cause deadly poisonous gas to escape into your home. It is also recommended you invest in carbon monoxide detectors to monitor the air in your home. To keep your home nice and toasty and to help curb high electric bills, install a smart thermostat. Keep your heat settings lower while you are asleep and program it to raise just before you wake.
