1. Insulate and weatherize – if you haven’t done this to your home over the past 50 years since the first energy crisis then you deserve high bills. This is step one in saving energy and being comfortable.
2. Thermostat settings – modern digital and smart thermostat comfort settings – 68 degrees “Home” setting; 55 or OFF “Sleep” setting; and 50 or OFF “Away” setting. A thermostat is not like an accelerator pedal, the higher you set it doesn’t make it get hot faster, it makes it run longer!
3. Keep heating supply registers and doors open if you have a central return – Forced-air or central air heating systems need to circulate the air in your house. If you close doors or block the gap under the door, the system will draw in air from outside (infiltration). Keep registers and doors open in unused rooms to prevent mold from growing and improve air circulation.
4. Wear winter clothes – lower your thermostat or turn it off and wear warm clothing.
5. Let the Sun in – open curtains on the sunny side of your house during the day and let it warm up your house. Close the curtains at night to keep the heat in.
6. Don’t use your dryer’s exhaust or your oven to heat your home. It will put warm moist air into the house which will cause mold to grow. Your gas dryer or oven you can poison your family with carbon monoxide. 
7. Tune-up your heating system to make sure it is operating properly. You don’t need this every year but should be done every 5 – 10 years depending on your heating system’s age. Older units should be checked more often. If anyone in your home gets headaches when the heating system runs call your gas utility company to test your system for carbon monoxide.
8. Heat pump users – heat pumps need to run full time because their temperature output isn’t as hot as a gas furnace. They can be turned down at night but have a long reheat time. 
9. Ceiling fans – if you use a ceiling fan to move warm air off of your ceiling reverse the direction (all ceiling fans are reversable) so that the fan blows upward, not down. Air blowing on you will cool you off even if it is warm air.
10. Take advantage of President Biden’s energy rebates and tax incentives starting in 2023 to upgrade the efficiency of your home. 

Tom’s Bonus Tip: Use other people’s/places heat. There are plenty of places you can go to that are heated and open to the public – coffee shops, restaurants, libraries, indoor malls, etc. Instead of spending your money on heating use the free heat available in these places.
