Tips to More Efficient Home Cooling
Avoid heat build-up in your home – The best way to keep your home cool is to keep the heat out. This can be done by closing the drapes on windows facing the sun (east-facing windows in the morning and west-facing windows in the afternoon). You should also try to avoid heat-generating activities, such as cooking, on hot days or during the hottest part of the day. If you are cooking, use your range fan to vent the hot air out of your house. By reducing the amount of heat in your home, you will have to use less energy to cool it.
Use ventilation and circulation to cool your home – Instead of automatically turning on the air conditioner on hot days, try cooling your home with window and ceiling fans. Circulating air can make your home feel cool and comfortable in a much more efficient way than air conditioning. There is also the option of a whole house fan (a large ventilating fan installed in you attic that expels hot air out of your home) which can circulate air throughout your entire home.
Keep air conditioning efficient and to a minimum – When you do have to use air conditioning, there are ways to make it more efficient. First of all, turn up the temperature setting on your air conditioner by a couple of degrees. Most people keep the temperature setting lower than it needs to be, hence using more energy than is needed to keep your home cool. It is recommended that you keep the temperature at about 25° C (77° F). Also, remember to turn off your air conditioner once your home has reached a comfortable temperature. By coupling minimum air conditioning with reducing the amount of heat entering your home, you can keep it cool without using excess energy. It isn’t recommended that you leave your air conditioner on when you leave your house, but if you’re going to do so, turn the temperature setting up a few more degrees while you’re gone to about 28° C (82° F). Also, remember to turn off your air conditioner if you’re going to be away from your home for more than a day. It is also important to make sure your cooling vents aren’t blocked so that the energy being used is going towards actually cooling your home and not being wasted. Furthermore, keep rooms that don't need cooling, such as closets, closed off when you're air conditioning.
Make sure your home isn’t losing cool air – By weather-stripping and caulking around windows, doors and electrical outlets on outer walls, you can prevent losing cool air from your home and prevent hot air from getting in. Improve your home’s insulation on outer walls, again to keep cool air in, and hot air out. You should also consider installing storm doors for the same reasons if your home doesn’t already have them. If you have a fireplace, keep the flue closed. These provide an extra barrier against the escape of cool air. All of these options will make cooling your home more efficient and will save you money on your energy bill.
Select energy efficient cooling systems – If you’re in the market for a new cooling system, there are many new technologies that are much more efficient than older versions. As with other appliances, you should look for the Energy Star logo and compare the amount of electricity each uses.
Use the coolest parts of your home – On hot days, parts of your house will naturally stay cooler than others. For example, if you have a basement it will remain cool even during the hottest part of the day (this is because the cool air in your home will sink down to your basement). One way you can reduce the amount of energy used to cool your home is to do more in cooler areas of your home. This way, you won't have to use energy to stay cool.
