A useful approach does not need to be complicated. It needs to be clear enough to repeat and flexible enough for real life.
Test cooling before the hottest day
Run air conditioning early enough to notice unusual noise, weak airflow, odors, or water where it should not be. Arrange qualified service for electrical or refrigerant problems rather than opening sealed equipment yourself.
Clean safe, accessible filters and keep outdoor equipment clear according to the manufacturer’s instructions. Renters should report problems through the property’s normal maintenance process.
Reduce heat entering the home
Close coverings on sun-facing windows during the hottest hours and reopen when outdoor air is cooler. Fans improve comfort for people but do not cool an empty room, so switch them off when leaving.
Plan several meals that require little oven use and identify a cooler public place you can visit during an outage or extreme heat advisory.
Check on people, not just equipment
Older adults, infants, people with chronic conditions, outdoor workers, and those without reliable cooling may need extra help. Follow local health guidance, know the signs of heat illness, and seek urgent help when symptoms are severe.
