How to Cool a Room Without AC: 10 Easy Ways

Living in a hot climate is lots of fun, days at the beach, barbecues and days by the pool. But, when bedtime rolls around, rolling around in a hot and sticky bed is no fun and causes detrimental insomnia. In many countries, an electric air conditioner is standard in every home. If an air conditioner is hard to come by where you live, fear not, we have some tricks and tips to cool your bedroom and cool you down for restful sleep.      

Insulated curtains or honeycomb blinds will keep the cool air inside your home in summer and the warm air inside in winter

How to Cool a Room Without AC

1. Switch to CFL/LED Bulbs

Have you ever noticed heat emanating from your table lamp? All light sources emanate heat but CFLs (compact fluorescent lamps) and LEDs (light emitting diodes) could be more energy saving than incandescent bulbs. While they may not make the room significantly cooler, they could put a dent in your electric bill.  

2. Invest in a Misting Fan

A misting fan is an outdoor electric fan that can cool spaces as large as 1,000 sq. ft. Stay cool when working in a garage or having a BBQ on the back porch. It works by blowing air and a light mist of water in your direction. Perfect to keep you cool on a hot day.  

3. Shut Off Computers and Screens When Not in Use

This may seem inconsequential but having electrical devices and chargers switched off when not in use can make a difference. Phone, tablet, desktop, and laptop chargers can get quite hot. Switch them off from the wall when not being used. The same for your devices, if they are plugged in and fully charged, save money on your electric bill by switching off from the wall. You could get a remote controlled extension cable and switch all your devices off with one click of a button.   

4. Switch to Insulated Curtains or Honeycomb Blinds 

Insulated curtains or honeycomb blinds will keep the cool air inside your home in summer and the warm air inside in winter. Reduce summer sunlight in your home by up to 90% with insulated curtains or honeycomb blinds. The drawback is that you will need to have the blinds and curtains closed all day, which may not be ideal, unless you’re a mushroom!

7. Switch to Grilling 

Using your cooker in the summer can turn your kitchen into a sauna. Invest in a BBQ and grill to your heart's content every day. Turn your back garden into the social hub of the neighborhood.    

8. Keep Your Blinds Closed 

Cooling house without ac can be as easy as closing your blinds. If you’re out of the house all day, close all your blinds and curtains before you leave. This blocks the hot sunlight from warming your home. When you return, open the blinds and some windows to let some fresh air circulate. 

9. Consider a Dehumidifier 

To make your room cooler, consider a dehumidifier. Humidity in your bedroom at night can make you feel more hot and sticky. The dehumidifier pulls moisture out of the air creating a more fresh sleep space. The collected water can be used to water your plants or for cleaning your floors or car.
