Tips to cool your home
- Open the windows at night & close them during the day. Average summer evening temperatures in southern Canada can range between 10-20 degrees each night. Use this free cool air to cool the inside of your home, & then close the windows before 8 am each morning to trap the coolness inside.
- Use fans at night to help draw in cool air from the windows on still nights when there isn’t much of a breeze.
- Use ceiling fans in main common rooms such as the kitchen, living room, as well as bedrooms to keep air circulating & remain cool.
- Use the furnace fan to draw the cool air from the basement to cool our house first before resorting to use A/C. The fan uses a lot less power, and the cool air in the basement can bring down the overall temperature of the main floor. Open the basement window each night to re-cool the basement and occasional use an energy star dehumidifier for a short time (in off peak hours) to take out the humidity.
- Run A/C at full speed. Air-conditioning systems are most efficient & better able to dehumidify when run at full speed, rather than being used for shorter periods at a less powerful speed to maintain a constant temperature all day.
- Keep your air conditioner out of the sun. The ideal location for a central air conditioner is on the north side of your home. While this may not be possible in every case, planting a shrub or tree for shade around your air conditioning unit, you can help it cool your home more efficiently.
Most Large Appliances give off a lot of Heat
- A lot of heat comes out of the refrigerator each time it runs. A normal incandescent light bulb in the refrigerator generates a lot of heat each time the door is opened, causing the fridge to warm up quickly & turn on. Try replacing the bulb with a LED light bulb that gives off less heat(note: CF bulbs don’t work as they need time to warm up). Also, try to take multiple items in & out of the fridge at once, rather than opening the door many times. Finally, make sure the coils at the back of your refrigerator are cleaned once a year (always unplug it before cleaning). This will keep it operating efficiently and will turn on less often.
- Cook outside when possible. Adopt the practice of using an outdoor Summer kitchen similar to many Mediterranean countries to keep all cooking heat outdoors. Try using the side-burners of the BBQ to boil vegetables, rice, pasta or even make spaghetti sauce.
- Use small convection oven (available at stores for $59) for cooking & baking when possible. It uses less power & gives off less heat. On hot sunny days try plugging it in the garage or outside to avoid bring the heat into your home all together.
- Boil hot water for cooking in the kettle rather than boiling on the stove. It is more efficient, uses less power, & puts less heat into the house than boiling water on a stove.
- Install a clothesline outside for laundry. Dryers use a lot of power & give off additional heat to your home in the summer.
- Replaced your TV with energy star LED. It uses less power & give off far less heat than other types of TVs.
