7 Tips To Keep House Cool Without AC

Discover energy-efficient strategies to keep your home comfortable during hot summer months without turning on the AC.

1

Night-Flush Ventilation

Open your windows at night for natural night-flush ventilation; close them in the morning to trap cool air.

2

Block Heat with Window Coverings 

Close curtains or blinds during peak sun hours to block solar heat gain—consider reflective window films for extra protection.

3

Insulate & Air Seal

Seal gaps and cracks around windows and doors with caulk or weatherstripping to keep hot air out and cool air in.

4

Cool Down After Dark

Run ovens, dishwashers, and laundry machines in the evening; hang laundry outside to dry and avoid dryer heat.

5

Grill Outdoors

Install awnings, pergolas, or plant shade trees near sun‑exposed windows to block afternoon rays.

6

Smart Fan Use

Position fans to draw in cooler air and exhaust hot air; set ceiling fans to rotate counterclockwise for a downward breeze.
