Don’t forget about your comfort
Whether the lights go out on a balmy summer day or a freezing winter night, without the use of your HVAC, you’ll no doubt be feeling the weather. If it’s hot, dress in lightweight clothing, crack the windows, close blinds to south-facing windows, and avoid hanging out in in sunny spots. If it’s cold, bundle up and do what you can to keep warm air in: Block leaky windows with blankets, and close doors to rooms you’re not using. Warm up with a fireplace, if you have one, but never use a gas oven for heat: It could emit fumes that endanger your family.
