1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsTo cool a room without central air, first keep sunlight and outdoor heat out: shade sunny windows, seal drafts, and limit heat from cooking. Use fans for personal comfort, not as room coolers. Open windows only when outdoor air is cooler and safe; if these measures are not enough, a properly sized room air conditioner is the reliable option. During extreme heat, prioritize safety over fan-only cooling.
Keep heat from getting into the room
Shade sunny windows
Close drapes or shades during hot, sunny periods. Ready.gov also recommends reflective window coverings designed to reflect heat back outdoors. These measures reduce heat gain; they do not produce cooled air.
Seal gaps
Weather-strip gaps around doors and windows to limit hot air entering the room. Sealing is most useful when outdoor air is hotter than indoor air, or when you are running a room air conditioner.
Reduce heat produced indoors
Use the stove and oven less during hot weather. Cooking adds heat to the home, so choose meals that need little or no cooking when practical. The CDC and U.S. Department of Energy both recommend limiting oven use during hot conditions.

Use fans for comfort, not as room cooling
Portable and ceiling fans move air but do not lower the room’s temperature. Moving air helps sweat evaporate from skin, which can make a person feel cooler. Direct airflow toward people when conditions are safe, and turn a fan off when nobody is in the room.
There is an important heat-safety limit: CDC guidance updated July 20, 2026 says to use indoor fans only when the room is below 90°F. Above 90°F, a fan can increase body temperature. CDC also warns that fans do not prevent heat-related illness when temperatures are very hot. Do not rely on a fan alone to protect anyone from dangerous heat.

Ventilate only when outdoor conditions help
When outdoor air is cooler than indoor air, opening suitable windows can flush heat from a room. Natural ventilation is most effective where nights are cool and breezes are regular, according to the U.S. Department of Energy.
- For cross-ventilation: Open windows on different sides of the space if the layout allows. Lower openings can bring cooler air in while higher openings let warmer air escape.
- For exhaust ventilation: A securely installed window exhaust fan can push warm indoor air outside. Provide a separate intake opening elsewhere, ideally on the shaded side, so replacement air can enter.
- Close windows when conditions change: Shut them when outdoor air becomes hotter than indoor air, or when pollution, security, or fall risks make opening them unsafe.
Ventilation moves outdoor air through the room; it is not a substitute for air conditioning when the outside air is hot or humid.

Choose a room air conditioner when you need dependable cooling
A room air conditioner actively cools the space, unlike a fan or open window. Choose its capacity for the room rather than assuming a larger unit is always better. ENERGY STAR’s room-air-conditioner guidance calls for adjustments to the base sizing: reduce capacity by 10% for a heavily shaded room, increase it by 10% for a very sunny room, add 600 BTU for each regular occupant beyond two, and add 4,000 BTU if the unit will be used in a kitchen. The page does not state a publication year for those adjustments.
Follow the unit’s installation instructions and insulate installation gaps; unsealed gaps can undermine comfort and efficiency. ENERGY STAR also recommends setting the thermostat as high as is comfortable and using an extra fan to spread cooled air through the room.

What to do if the room remains dangerously hot
Reduce physical heat exposure and drink water. If home conditions remain unsafe, go to an air-conditioned location; Ready.gov gives libraries and shopping malls as examples. CDC guidance says to seek medical care for heat-illness symptoms including cramps, headache, nausea, or vomiting. People at higher risk from heat should not wait for passive cooling measures to make an overheated room safe.
