Cool Your Home Without Air Conditioning

Don’t have air conditioning? Air conditioner not working? Maybe you want to cut your utility bills. Here are some affordable ways to keep your home cool during the summer months.


The early morning air is cooler. Open up doors and windows that allow air to flow in and out. This will create cross ventilation and bring room temperatures down. After 30 minutes or so, close windows and doors to capture cooler air. (Not advised if you or other occupants suffer from organic allergies)

2) Keep drapes and blinds closed during the day

After cooling your rooms in the morning, be sure to close drapes, blinds, and shutters to block sunlight that can quickly heat room temps.

3) Set your ceiling fan for summer rotation

For a maximum cooling effect, make sure ceiling fans spin in the direction that pushes air down (typically counter-clockwise) rather than sucking it upward. Most fans have a winter and summer setting on the housing. Don’t leave fans on when the room is not occupied. Heat can be generated from some fan motors when left running continuously.

4) Reduce heat build-up in your attic

Heat can quickly build up in your attic due to the hot summer sun beating down on the roof. This heats your attic air. The heat from your attic can radiate down to the living spaces below. Use roof vents or an attic fan to exhaust hot air from your attic preventing the hot air from penetrating living spaces. Be sure your attic is adequately insulated. Good insulation will slow heat transfer from your attic down to living spaces. Learn more about attic fans here>

5) A whole house fan is another way to cool your home without air conditioning

To quickly remove hot air from a home that does not have air conditioning, consider installing a whole-house fan. A properly sized whole house fan can quickly replace hot, stagnant air in your home with cooler outside air within minutes. In addition, a whole house fan is a cost-effective alternative to central air conditioning and can dramatically reduce the cooling cost even if you have central air.

Central air conditioning can be a huge expense for existing or older homes. However, a whole-house fan can be installed easily compared to a central system and at a fraction of the cost.

A whole house fan operates best with proper attic exhaust vents. Before activating the fan, open up front, side, and back doors in the early morning and late evening when temperatures are lowest. Then activate the fan. It will pull in the cool air and allow hot air to exhaust through roof vents.
