Keeping Cool Tip #1: Close Blinds and Curtains
Inexpensive mini blinds or curtains can work wonders for reducing the sunlight and heat streaming in through your windows! At my house, installing inexpensive blinds on the south-facing windows completely changed the temperature in that part of the house.
Make sure blinds or curtains are white on the side facing the outside. Solar sun screens and window film are other options that can greatly reduce the heat coming through windows.
CFL light bulbs produce much less heat than incandescent bulbs.
Keeping Cool Tip #2: Install Cool Lighting
Incandescent light bulbs can significantly heat up a room. Replace standard bulbs with high-efficiency, low-heat CFL (compact fluorescent lights) or LED (light emitting diodes) bulbs, and turn off lights when not needed.
Cooking outdoors on a grill, rather than inside on a stove, keeps your house cooler.
Keeping Cool Tip #3: Cook Wisely
Eat cold meals, cook outside on the grill, or use the microwave for cooking when possible to minimize heat indoors.
When you do cook indoors:
- Cover pots to minimize indoor humidity.
- Use range hood or microwave vent fan to vent hot air outside.
- Turn oven off a few minutes before food is cooked to reduce oven heat.
- Check the oven by turning on the light and looking through the glass, rather than opening the oven door.
Keeping Cool Tip #4: Turn Off Electronics
Computers, TVs, and other electronics generate quite a bit of heat when sitting idle or even when turned off, so unplug devices when not in use. An easy way to do this is to plug electronics into a surge protector which has an on/off switch, then turn the switch off when the devices are not in use.
Keeping Cool Tip #5: Repair Windows and Doors
Windows and doors are a major source of heat gain in the house, so keep windows closed and locked and doors tightly closed to prevent cool air from escaping. Older single pane windows and doors without proper weather stripping are the worst culprits.
If you can’t replace your windows and doors with more energy efficient models, repair any gaps in or replace weather stripping around and under windows and doors. Also, don’t open windows at night unless the temperature drops to the mid-70s F or lower.
Keeping Cool Tip #6: Use Fans for Cooling
A paddle ceiling fan or portable fan uses much less energy than an air conditioner, but they’re only effective when you’re in the room to feel the cooling, so turn them off when you leave.
Run ceiling fans in a counterclockwise direction (when looking up) when you’re in the room to help keep you cool through evaporation. This will allow you to set the thermostat on your air conditioner higher and save energy.
Keeping Cool Tip #7: Clean Air Conditioner Filters
While your AC system is cranking away, the filter is getting more use than usual. By changing the AC air filter every month or so during the highest use months allows air to flow easily through your HVAC system, making it run more efficiently and saving energy.
Keeping Cool Tip #8: Put Off Chores
You heard me! Don’t run the dishwasher, clothes washer/dryer, or other appliances during the heat of the day, since these machines generate heat and humidity that will be hard to overcome. Put these chores off until evening when possible.
When cleaning clothes:
- Wash clothes in cold water.
- Run the washer or dryer only if you have a full load.
- Choose the shortest wash cycle that gets the job done.
- Clean dryer vent pipe and lint screen regularly to lower drying time.
- Dry clothes outside on a clothesline when possible.
Keeping Cool Tip #9: Use Less Hot Water
Turn your hot water heater down to a lower temperature setting so it will run less and produce less heat.
Hot showers create a lot of excess heat and humidity in the house, so:
- Take shorter showers to reduce humidity and heat.
- Take cool – rather than hot – showers.
- Run the bathroom exhaust fan when showering or bathing, and keep it running for 20 minutes afterward, to remove excess heat and humidity.
Keeping Cool Tip #10: Plan Ahead
Long term strategies to keep your house cooler include:
- Plant shade trees on the south and west sides of the house.
- Install insulated glass windows with low-E coating or storm windows.
- Add awnings over sunny windows.
- Install additional attic insulation
- Replace existing roof with cool shingles or light-colored roofing
